Subject: tests: Fix truncation test

data/truncation.xml was corrupted at some point and was not actually valid.
Fix the file and make the test fail if we can't parse truncation.xml at all.

Subject: Do not emit surrounding whitespace for text nodes

Previously we omitted extra whitespace for single PCDATA/CDATA children, but in
mixed content there was extra indentation before/after text nodes.

One of the problems with that is that the text that you saved is not exactly
the same as the parsing result using default flags (parse_trim_pcdata helps).

Another problem is that parse-format cycles do not have a fixed point for mixed
content - the result expands indefinitely. Some XML libraries, like Python
minidom, have the same issue, but this is definitely a problem.

Pretty-printing mixed content is hard. It seems that the only other sensible
choice is to switch mixed content nodes to raw formatting. In a way the code in
this change is a weaker version of that - it removes indentation around text
nodes but still keeps it around element siblings/children.

Thus we can switch to mixed-raw formatting at some point later, which will be
a superset of the current behavior.

To do this we have to either switch at the first text node (.NET XmlDocument
does that), or scan the children of each element for a possible text node and
switch before we output the first child.

The former behavior seems non-intuitive (and a bit broken); unfortunately, the
latter behavior can cost up to 20% of the output time for trees *without* mixed
content.

Fixes #13.

 Maintenance release. Changes:
 
 * Specification changes:
+    # Attribute/text values now use more digits when printing floating point numbers to guarantee round-tripping.
+    # Text nodes no longer get extra surrounding whitespace when pretty-printing nodes with mixed contents
 
 * Bug fixes:
+    # Fixed translate and normalize-space XPath functions to no longer return internal NUL characters
+    # Fixed buffer overrun on malformed comments inside DOCTYPE sections
+    # DOCTYPE parsing can no longer run out of stack space on malformed inputs (XML parsing is now using bounded stack space)
+    # Adjusted processing instruction output to avoid malformed documents if the PI value contains "?>"

+[[overview]]
+== Overview
+
+[[overview.introduction]]
+=== Introduction
+
+http://pugixml.org/[pugixml] is a light-weight C{plus}{plus} XML processing library. It consists of a DOM-like interface with rich traversal/modification capabilities, an extremely fast XML parser which constructs the DOM tree from an XML file/buffer, and an <<xpath,XPath 1.0 implementation>> for complex data-driven tree queries. Full Unicode support is also available, with <<dom.unicode,two Unicode interface variants>> and conversions between different Unicode encodings (which happen automatically during parsing/saving). The library is <<install.portability,extremely portable>> and easy to integrate and use. pugixml is developed and maintained since 2006 and has many users. All code is distributed under the <<overview.license,MIT license>>, making it completely free to use in both open-source and proprietary applications.
+
+pugixml enables very fast, convenient and memory-efficient XML document processing. However, since pugixml has a DOM parser, it can't process XML documents that do not fit in memory; also the parser is a non-validating one, so if you need DTD or XML Schema validation, the library is not for you.
+
+This is the complete manual for pugixml, which describes all features of the library in detail. If you want to start writing code as quickly as possible, you are advised to link:quickstart.html[read the quick start guide first].
+
+NOTE: No documentation is perfect; neither is this one. If you encounter a description that is unclear, a statement that is incorrect or a syntactic error, please file an issue as described in <<overview.feedback>>.
+
+[[overview.feedback]]
+=== Feedback
+
+If you believe you've found a bug in pugixml (bugs include compilation problems (errors/warnings), crashes, performance degradation and incorrect behavior), please file an issue via https://github.com/zeux/pugixml/issues/new[issue submission form]. Be sure to include the relevant information so that the bug can be reproduced: the version of pugixml, compiler version and target architecture, the code that uses pugixml and exhibits the bug, etc.
+
+Feature requests can be reported the same way as bugs, so if you're missing some functionality in pugixml or if the API is rough in some places and you can suggest an improvement, https://github.com/zeux/pugixml/issues/new[file an issue]. However please note that there are many factors when considering API changes (compatibility with previous versions, API redundancy, etc.), so generally features that can be implemented via a small function without pugixml modification are not accepted. However, all rules have exceptions.
+
+If you have a contribution to pugixml, such as build script for some build system/IDE, or a well-designed set of helper functions, or a binding to some language other than C{plus}{plus}, please https://github.com/zeux/pugixml/issues/new[file an issue]. You can include the relevant patches as issue attachments. Your contribution has to be distributed under the terms of a license that's compatible with pugixml license; i.e. GPL/LGPL licensed code is not accepted.
+
+If filing an issue is not possible due to privacy or other concerns, you can contact pugixml author by e-mail directly: arseny.kapoulkine@gmail.com.
+
+[[overview.thanks]]
+=== Acknowledgments
+
+pugixml could not be developed without the help from many people; some of them are listed in this section. If you've played a part in pugixml development and you can not find yourself on this list, I'm truly sorry; please <<email,send me an e-mail>> so I can fix this.

+
+[[install]]
+== Installation
+
+[[install.getting]]
+=== Getting pugixml
+
+pugixml is distributed in source form. You can either download a source distribution or clone the Git repository.
+
+[[install.getting.source]]
+==== Source distributions
+
+You can download the latest source distribution via one of the following links:
+
+* https://github.com/zeux/pugixml/releases/download/v{version}/pugixml-{version}.zip
+* https://github.com/zeux/pugixml/releases/download/v{version}/pugixml-{version}.tar.gz
+
+The distribution contains library source, documentation (the manual you're reading now and the quick start guide) and some code examples. After downloading the distribution, install pugixml by extracting all files from the compressed archive. The files have different line endings depending on the archive format - `.zip` archive has Windows line endings, `.tar.gz` archive has Unix line endings. Otherwise the files in both archives are identical.
+
+If you need an older version, you can download it from the https://github.com/zeux/pugixml/releases[version archive].
+
+[[install.getting.git]]
+==== Git repository
+
+The Git repository is located at https://github.com/zeux/pugixml/. There is a Git tag "v\{version\}" for each version; also there is the "latest" tag, which always points to the latest stable release.
+
+For example, to checkout the current version, you can use this command:
+
+----
+git clone https://github.com/zeux/pugixml
+cd pugixml
+git checkout v{version} TODO
+----
+
+The repository contains library source, documentation, code examples and full unit test suite.
+
+Use `latest` tag if you want to automatically get new versions. Use other tags if you want to switch to new versions only explicitly. Also please note that the master branch contains the work-in-progress version of the code; while this means that you can get new features and bug fixes from master without waiting for a new release, this also means that occasionally the code can be broken in some configurations.
+
+[[install.getting.subversion]]
+===== Subversion repository
+
+You can access the Git repository via Subversion using https://github.com/zeux/pugixml URL. For example, to checkout the current version, you can use this command:
+
+----
+svn checkout https://github.com/zeux/pugixml/tags/v{version} pugixml TODO
+----
+
+[[install.building]]
+=== Building pugixml
+
+pugixml is distributed in source form without any pre-built binaries; you have to build them yourself.
+ 
+The complete pugixml source consists of three files - one source file, `pugixml.cpp`, and two header files, `pugixml.hpp` and `pugiconfig.hpp`. `pugixml.hpp` is the primary header which you need to include in order to use pugixml classes/functions; `pugiconfig.hpp` is a supplementary configuration file (see <<install.building.config>>). The rest of this guide assumes that `pugixml.hpp` is either in the current directory or in one of include directories of your projects, so that `#include "pugixml.hpp"` can find the header; however you can also use relative path (i.e. `#include "../libs/pugixml/src/pugixml.hpp"`) or include directory-relative path (i.e. `#include <xml/thirdparty/pugixml/src/pugixml.hpp>`).
+ 
+[[install.building.embed]]
+==== Building pugixml as a part of another static library/executable
+
+The easiest way to build pugixml is to compile the source file, `pugixml.cpp`, along with the existing library/executable. This process depends on the method of building your application; for example, if you're using Microsoft Visual Studio[ftnt trademarks All trademarks used are properties of their respective owners.], Apple Xcode, Code::Blocks or any other IDE, just add `pugixml.cpp` to one of your projects.
+
+If you're using Microsoft Visual Studio and the project has precompiled headers turned on, you'll see the following error messages:
+
+----
+pugixml.cpp(3477) : fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "stdafx.h"' to your source?
+----
+
+The correct way to resolve this is to disable precompiled headers for `pugixml.cpp`; you have to set "Create/Use Precompiled Header" option (Properties dialog -> C/C{plus}{plus} -> Precompiled Headers -> Create/Use Precompiled Header) to "Not Using Precompiled Headers". You'll have to do it for all project configurations/platforms (you can select Configuration "All Configurations" and Platform "All Platforms" before editing the option):

+[$images/next.png]
+[@images/vs2005_pch4.png [$images/vs2005_pch4_thumb.png]]
+]] ]
+ 
+[[install.building.static]]
+==== Building pugixml as a standalone static library
+ 
+It's possible to compile pugixml as a standalone static library. This process depends on the method of building your application; pugixml distribution comes with project files for several popular IDEs/build systems. There are project files for Apple XCode3, Code::Blocks, Codelite, Microsoft Visual Studio 2005, 2008, 2010, and configuration scripts for CMake and premake4. You're welcome to submit project files/build scripts for other software; see <<overview.feedback>>. 
+
+There are two projects for each version of Microsoft Visual Studio: one for dynamically linked CRT, which has a name like `pugixml_vs2008.vcproj`, and another one for statically linked CRT, which has a name like `pugixml_vs2008_static.vcproj`. You should select the version that matches the CRT used in your application; the default option for new projects created by Microsoft Visual Studio is dynamically linked CRT, so unless you changed the defaults, you should use the version with dynamic CRT (i.e. `pugixml_vs2008.vcproj` for Microsoft Visual Studio 2008).
+
+In addition to adding pugixml project to your workspace, you'll have to make sure that your application links with pugixml library. If you're using Microsoft Visual Studio 2005/2008, you can add a dependency from your application project to pugixml one. If you're using Microsoft Visual Studio 2010, you'll have to add a reference to your application project instead. For other IDEs/systems, consult the relevant documentation.
+
+[table
+[[Microsoft Visual Studio 2005/2008][Microsoft Visual Studio 2010]]

+]] ]
+
+[[install.building.shared]]
+==== Building pugixml as a standalone shared library
+ 
+It's possible to compile pugixml as a standalone shared library. The process is usually similar to the static library approach; however, no preconfigured projects/scripts are included into pugixml distribution, so you'll have to do it yourself. Generally, if you're using GCC-based toolchain, the process does not differ from building any other library as DLL (adding -shared to compilation flags should suffice); if you're using MSVC-based toolchain, you'll have to explicitly mark exported symbols with a declspec attribute. You can do it by defining [link PUGIXML_API] macro, i.e. via `pugiconfig.hpp`:
+
+[source]
+----
+#ifdef _DLL
+#define PUGIXML_API __declspec(dllexport)
+#else
+#define PUGIXML_API __declspec(dllimport)
+#endif
+----
+
+CAUTION: If you're using STL-related functions, you should use the shared runtime library to ensure that a single heap is used for STL allocations in your application and in pugixml; in MSVC, this means selecting the 'Multithreaded DLL' or 'Multithreaded Debug DLL' to 'Runtime library' property (/MD or /MDd linker switch). You should also make sure that your runtime library choice is consistent between different projects.
+
+[#PUGIXML_HEADER_ONLY]
+[[install.building.header]]
+==== Using pugixml in header-only mode
+
+It's possible to use pugixml in header-only mode. This means that all source code for pugixml will be included in every translation unit that includes `pugixml.hpp`. This is how most of Boost and STL libraries work.
+
+Note that there are advantages and drawbacks of this approach. Header mode may improve tree traversal/modification performance (because many simple functions will be inlined), if your compiler toolchain does not support link-time optimization, or if you have it turned off (with link-time optimization the performance should be similar to non-header mode). However, since compiler now has to compile pugixml source once for each translation unit that includes it, compilation times may increase noticeably. If you want to use pugixml in header mode but do not need XPath support, you can consider disabling it by using [link PUGIXML_NO_XPATH] define to improve compilation time.
+
+Enabling header-only mode is a two-step process:
+
+* You have to define `PUGIXML_HEADER_ONLY`
+* You have to include `pugixml.cpp` whenever you include pugixml.hpp
+
+Both of these are best done via `pugiconfig.hpp` like this:
+
+[source]
+----
+#define PUGIXML_HEADER_ONLY
+#include "pugixml.cpp"
+----
+
+Note that it is safe to compile `pugixml.cpp` if `PUGIXML_HEADER_ONLY` is defined - so if you want to i.e. use header-only mode only in Release configuration, you
+can include pugixml.cpp in your project (see <<install.building.embed>>), and conditionally enable header-only mode in `pugiconfig.hpp`, i.e.:
+
+[source]
+----
+#ifndef _DEBUG
+    #define PUGIXML_HEADER_ONLY
+    #include "pugixml.cpp"
+#endif
+----
+
+[[install.building.config]]
+==== Additional configuration options
+
+pugixml uses several defines to control the compilation process. There are two ways to define them: either put the needed definitions to `pugiconfig.hpp` (it has some examples that are commented out) or provide them via compiler command-line. Consistency is important: the definitions should match in all source files that include `pugixml.hpp` (including pugixml sources) throughout the application. Adding defines to `pugiconfig.hpp` lets you guarantee this, unless your macro definition is wrapped in preprocessor `#if`/`#ifdef` directive and this directive is not consistent. `pugiconfig.hpp` will never contain anything but comments, which means that when upgrading to a new version, you can safely leave your modified version intact.
+
+[anchor PUGIXML_WCHAR_MODE] define toggles between UTF-8 style interface (the in-memory text encoding is assumed to be UTF-8, most functions use `char` as character type) and UTF-16/32 style interface (the in-memory text encoding is assumed to be UTF-16/32, depending on `wchar_t` size, most functions use `wchar_t` as character type). See <<dom.unicode>> for more details.
+
+[anchor PUGIXML_NO_XPATH] define disables XPath. Both XPath interfaces and XPath implementation are excluded from compilation. This option is provided in case you do not need XPath functionality and need to save code space.
+
+[anchor PUGIXML_NO_STL] define disables use of STL in pugixml. The functions that operate on STL types are no longer present (i.e. load/save via iostream) if this macro is defined. This option is provided in case your target platform does not have a standard-compliant STL implementation.
+
+[anchor PUGIXML_NO_EXCEPTIONS] define disables use of exceptions in pugixml. This option is provided in case your target platform does not have exception handling capabilities.
+
+[anchor PUGIXML_API], [anchor PUGIXML_CLASS] and [anchor PUGIXML_FUNCTION] defines let you specify custom attributes (i.e. declspec or calling conventions) for pugixml classes and non-member functions. In absence of `PUGIXML_CLASS` or `PUGIXML_FUNCTION` definitions, `PUGIXML_API` definition is used instead. For example, to specify fixed calling convention, you can define `PUGIXML_FUNCTION` to i.e. `__fastcall`. Another example is DLL import/export attributes in MSVC (see <<install.building.shared>>).
+
+NOTE: In that example `PUGIXML_API` is inconsistent between several source files; this is an exception to the consistency rule.
+
+[anchor PUGIXML_MEMORY_PAGE_SIZE], [anchor PUGIXML_MEMORY_OUTPUT_STACK] and [anchor PUGIXML_MEMORY_XPATH_PAGE_SIZE] can be used to customize certain important sizes to optimize memory usage for the application-specific patterns. For details see <<dom.memory.tuning>>.
+
+[anchor PUGIXML_HAS_LONG_LONG] define enables support for `long long` type in pugixml. This define is automatically enabled if your platform is known to have `long long` support (i.e. has C{plus}{plus}-11 support or uses a reasonably modern version of a known compiler); if pugixml does not recognize that your platform supports `long long` but in fact it does, you can enable the define manually.
+ 
+[[install.portability]]
+=== Portability
+
+pugixml is written in standard-compliant C{plus}{plus} with some compiler-specific workarounds where appropriate. pugixml is compatible with the C{plus}{plus}11 standard, but does not require C{plus}{plus}11 support. Each version is tested with a unit test suite (with code coverage about 99%) on the following platforms:
+
+* Microsoft Windows:
+    * Borland C{plus}{plus} Compiler 5.82
+    * Digital Mars C{plus}{plus} Compiler 8.51
+    * Intel C{plus}{plus} Compiler 8.0, 9.0 x86/x64, 10.0 x86/x64, 11.0 x86/x64
+    * Metrowerks CodeWarrior 8.0
+    * Microsoft Visual C{plus}{plus} 6.0, 7.0 (2002), 7.1 (2003), 8.0 (2005) x86/x64, 9.0 (2008) x86/x64, 10.0 (2010) x86/x64, 11.0 (2011) x86/x64/ARM, 12.0 (2013) x86/x64/ARM and some CLR versions
+    * MinGW (GCC) 3.4, 4.4, 4.5, 4.6 x64
+
+* Linux (GCC 4.4.3 x86/x64, GCC 4.8.1 x64, Clang 3.2 x64)
+* FreeBSD (GCC 4.2.1 x86/x64)
+* Apple MacOSX (GCC 4.0.1 x86/x64/PowerPC)
+* Sun Solaris (sunCC x86/x64)
+* Microsoft Xbox 360
+* Nintendo Wii (Metrowerks CodeWarrior 4.1)
+* Sony Playstation Portable (GCC 3.4.2)
+* Sony Playstation 3 (GCC 4.1.1, SNC 310.1)
+* Various portable platforms (Android NDK, BlackBerry NDK, Samsung bada, Windows CE)
+
+[[dom]]
+== Document object model
+
+pugixml stores XML data in DOM-like way: the entire XML document (both document structure and element data) is stored in memory as a tree. The tree can be loaded from a character stream (file, string, C{plus}{plus} I/O stream), then traversed with the special API or XPath expressions. The whole tree is mutable: both node structure and node/attribute data can be changed at any time. Finally, the result of document transformations can be saved to a character stream (file, C{plus}{plus} I/O stream or custom transport).
+
+[[dom.tree]]
+=== Tree structure
+
+The XML document is represented with a tree data structure. The root of the tree is the document itself, which corresponds to C{plus}{plus} type [link xml_document]. Document has one or more child nodes, which correspond to C{plus}{plus} type [link xml_node]. Nodes have different types; depending on a type, a node can have a collection of child nodes, a collection of attributes, which correspond to C{plus}{plus} type [link xml_attribute], and some additional data (i.e. name).
+
+[#xml_node_type]
+The tree nodes can be of one of the following types (which together form the enumeration `xml_node_type`):
+
+* Document node ([anchor node_document]) - this is the root of the tree, which consists of several child nodes. This node corresponds to [link xml_document] class; note that [link xml_document] is a sub-class of [link xml_node], so the entire node interface is also available. However, document node is special in several ways, which are covered below. There can be only one document node in the tree; document node does not have any XML representation.
+[lbr]
+
+* Element/tag node ([anchor node_element]) - this is the most common type of node, which represents XML elements. Element nodes have a name, a collection of attributes and a collection of child nodes (both of which may be empty). The attribute is a simple name/value pair. The example XML representation of element nodes is as follows:
+
+----
+<node attr="value"><child/></node>
+----
+
+[:There are two element nodes here: one has name `"node"`, single attribute `"attr"` and single child `"child"`, another has name `"child"` and does not have any attributes or child nodes.]
+
+* Plain character data nodes ([anchor node_pcdata]) represent plain text in XML. PCDATA nodes have a value, but do not have a name or children/attributes. Note that *plain character data is not a part of the element node but instead has its own node*; an element node can have several child PCDATA nodes. The example XML representation of text nodes is as follows:
+
+----
+<node> text1 <child/> text2 </node>
+----
+
+[:Here `"node"` element has three children, two of which are PCDATA nodes with values `" text1 "` and `" text2 "`.]
+
+* Character data nodes ([anchor node_cdata]) represent text in XML that is quoted in a special way. CDATA nodes do not differ from PCDATA nodes except in XML representation - the above text example looks like this with CDATA:
+
+----
+<node> <![CDATA[[text1]]> <child/> <![CDATA[[text2]]> </node>
+----
+
+[:CDATA nodes make it easy to include non-escaped <, & and > characters in plain text. CDATA value can not contain the character sequence ]]>, since it is used to determine the end of node contents.]
+
+* Comment nodes ([anchor node_comment]) represent comments in XML. Comment nodes have a value, but do not have a name or children/attributes. The example XML representation of a comment node is as follows:
+
+----
+<!-- comment text -->
+----
+
+[:Here the comment node has value `"comment text"`. By default comment nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with [link parse_comments] flag.]
+
+* Processing instruction node ([anchor node_pi]) represent processing instructions (PI) in XML. PI nodes have a name and an optional value, but do not have children/attributes. The example XML representation of a PI node is as follows:
+
+----
+<?name value?>
+----
+
+[:Here the name (also called PI target) is `"name"`, and the value is `"value"`. By default PI nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with [link parse_pi] flag.]
+
+* Declaration node ([anchor node_declaration]) represents document declarations in XML. Declaration nodes have a name (`"xml"`) and an optional collection of attributes, but do not have value or children. There can be only one declaration node in a document; moreover, it should be the topmost node (its parent should be the document). The example XML representation of a declaration node is as follows:
+
+----
+<?xml version="1.0"?>
+----
+
+[:Here the node has name `"xml"` and a single attribute with name `"version"` and value `"1.0"`. By default declaration nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with [link parse_declaration] flag. Also, by default a dummy declaration is output when XML document is saved unless there is already a declaration in the document; you can disable this with [link format_no_declaration] flag.]
+
+* Document type declaration node ([anchor node_doctype]) represents document type declarations in XML. Document type declaration nodes have a value, which corresponds to the entire document type contents; no additional nodes are created for inner elements like `<!ENTITY>`. There can be only one document type declaration node in a document; moreover, it should be the topmost node (its parent should be the document). The example XML representation of a document type declaration node is as follows:
+
+----
+<!DOCTYPE greeting [ <!ELEMENT greeting (#PCDATA)> ]>
+----
+
+[:Here the node has value `"greeting [ <!ELEMENT greeting (#PCDATA)> ]"`. By default document type declaration nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with [link parse_doctype] flag.]
+
+Finally, here is a complete example of XML document and the corresponding tree representation (link:samples/tree.xml[]):

+[[dom.cpp]]
+=== C{plus}{plus} interface
+
+NOTE: All pugixml classes and functions are located in the `pugi` namespace; you have to either use explicit name qualification (i.e. `pugi::xml_node`), or to gain access to relevant symbols via `using` directive (i.e. `using pugi::xml_node;` or `using namespace pugi;`). The namespace will be omitted from all declarations in this documentation hereafter; all code examples will use fully qualified names.
+
+Despite the fact that there are several node types, there are only three C{plus}{plus} classes representing the tree (`xml_document`, `xml_node`, `xml_attribute`); some operations on `xml_node` are only valid for certain node types. The classes are described below.
+
+[#xml_document]
+[#xml_document::document_element]
+`xml_document` is the owner of the entire document structure; it is a non-copyable class. The interface of `xml_document` consists of loading functions (see <<loading>>), saving functions (see <<saving>>) and the entire interface of `xml_node`, which allows for document inspection and/or modification. Note that while `xml_document` is a sub-class of `xml_node`, `xml_node` is not a polymorphic type; the inheritance is present only to simplify usage. Alternatively you can use the `document_element` function to get the element node that's the immediate child of the document.
+
+[#xml_document::ctor]
+[#xml_document::dtor]
+[#xml_document::reset]
+Default constructor of `xml_document` initializes the document to the tree with only a root node (document node). You can then populate it with data using either tree modification functions or loading functions; all loading functions destroy the previous tree with all occupied memory, which puts existing node/attribute handles for this document to invalid state. If you want to destroy the previous tree, you can use the `xml_document::reset` function; it destroys the tree and replaces it with either an empty one or a copy of the specified document. Destructor of `xml_document` also destroys the tree, thus the lifetime of the document object should exceed the lifetimes of any node/attribute handles that point to the tree.
+
+CAUTION: While technically node/attribute handles can be alive when the tree they're referring to is destroyed, calling any member function for these handles results in undefined behavior. Thus it is recommended to make sure that the document is destroyed only after all references to its nodes/attributes are destroyed.
+
+[#xml_node]
+[#xml_node::type]
+`xml_node` is the handle to document node; it can point to any node in the document, including the document node itself. There is a common interface for nodes of all types; the actual [link xml_node_type node type] can be queried via the `xml_node::type()` method. Note that `xml_node` is only a handle to the actual node, not the node itself - you can have several `xml_node` handles pointing to the same underlying object. Destroying `xml_node` handle does not destroy the node and does not remove it from the tree. The size of `xml_node` is equal to that of a pointer, so it is nothing more than a lightweight wrapper around a pointer; you can safely pass or return `xml_node` objects by value without additional overhead.
+
+[#node_null]
+There is a special value of `xml_node` type, known as null node or empty node (such nodes have type `node_null`). It does not correspond to any node in any document, and thus resembles null pointer. However, all operations are defined on empty nodes; generally the operations don't do anything and return empty nodes/attributes or empty strings as their result (see documentation for specific functions for more detailed information). This is useful for chaining calls; i.e. you can get the grandparent of a node like so: `node.parent().parent()`; if a node is a null node or it does not have a parent, the first `parent()` call returns null node; the second `parent()` call then also returns null node, which makes error handling easier.
+
+[#xml_attribute]
+`xml_attribute` is the handle to an XML attribute; it has the same semantics as `xml_node`, i.e. there can be several `xml_attribute` handles pointing to the same underlying object and there is a special null attribute value, which propagates to function results.
+
+[#xml_attribute::ctor]
+[#xml_node::ctor]
+Both `xml_node` and `xml_attribute` have the default constructor which initializes them to null objects.
+
+[#xml_attribute::comparison]
+[#xml_node::comparison]
+`xml_node` and `xml_attribute` try to behave like pointers, that is, they can be compared with other objects of the same type, making it possible to use them as keys in associative containers. All handles to the same underlying object are equal, and any two handles to different underlying objects are not equal. Null handles only compare as equal to themselves. The result of relational comparison can not be reliably determined from the order of nodes in file or in any other way. Do not use relational comparison operators except for search optimization (i.e. associative container keys).
+
+[#xml_attribute::hash_value]
+[#xml_node::hash_value]
+If you want to use `xml_node` or `xml_attribute` objects as keys in hash-based associative containers, you can use the `hash_value` member functions. They return the hash values that are guaranteed to be the same for all handles to the same underlying object. The hash value for null handles is 0.
+
+[#xml_attribute::unspecified_bool_type]
+[#xml_node::unspecified_bool_type]
+[#xml_attribute::empty]
+[#xml_node::empty]
+Finally handles can be implicitly cast to boolean-like objects, so that you can test if the node/attribute is empty with the following code: `if (node) { ... }` or `if (!node) { ... } else { ... }`. Alternatively you can check if a given `xml_node`/`xml_attribute` handle is null by calling the following methods:
+
+[source]
+----
+bool xml_attribute::empty() const;
+bool xml_node::empty() const;
+----
+
+Nodes and attributes do not exist without a document tree, so you can't create them without adding them to some document. Once underlying node/attribute objects are destroyed, the handles to those objects become invalid. While this means that destruction of the entire tree invalidates all node/attribute handles, it also means that destroying a subtree (by calling [link xml_node::remove_child]) or removing an attribute invalidates the corresponding handles. There is no way to check handle validity; you have to ensure correctness through external mechanisms.
+
+[[dom.unicode]]
+=== Unicode interface
+
+There are two choices of interface and internal representation when configuring pugixml: you can either choose the UTF-8 (also called char) interface or UTF-16/32 (also called wchar_t) one. The choice is controlled via [link PUGIXML_WCHAR_MODE] define; you can set it via `pugiconfig.hpp` or via preprocessor options, as discussed in <<install.building.config>>. If this define is set, the wchar_t interface is used; otherwise (by default) the char interface is used. The exact wide character encoding is assumed to be either UTF-16 or UTF-32 and is determined based on the size of `wchar_t` type.
+
+NOTE: If the size of `wchar_t` is 2, pugixml assumes UTF-16 encoding instead of UCS-2, which means that some characters are represented as two code points.
+
+All tree functions that work with strings work with either C-style null terminated strings or STL strings of the selected character type. For example, node name accessors look like this in char mode:
+
+[source]
+----
+const char* xml_node::name() const;
+bool xml_node::set_name(const char* value);
+----
+
+and like this in wchar_t mode:
+
+[source]
+----
+const wchar_t* xml_node::name() const;
+bool xml_node::set_name(const wchar_t* value);
+----
+
+[#char_t]
+[#string_t]
+There is a special type, `pugi::char_t`, that is defined as the character type and depends on the library configuration; it will be also used in the documentation hereafter. There is also a type `pugi::string_t`, which is defined as the STL string of the character type; it corresponds to `std::string` in char mode and to `std::wstring` in wchar_t mode.
+
+In addition to the interface, the internal implementation changes to store XML data as `pugi::char_t`; this means that these two modes have different memory usage characteristics. The conversion to `pugi::char_t` upon document loading and from `pugi::char_t` upon document saving happen automatically, which also carries minor performance penalty. The general advice however is to select the character mode based on usage scenario, i.e. if UTF-8 is inconvenient to process and most of your XML data is non-ASCII, wchar_t mode is probably a better choice.
+
+[#as_utf8]
+[#as_wide]
+There are cases when you'll have to convert string data between UTF-8 and wchar_t encodings; the following helper functions are provided for such purposes:
+
+[source]
+----
+std::string as_utf8(const wchar_t* str);
+std::wstring as_wide(const char* str);
+----
+
+Both functions accept a null-terminated string as an argument `str`, and return the converted string. `as_utf8` performs conversion from UTF-16/32 to UTF-8; `as_wide` performs conversion from UTF-8 to UTF-16/32. Invalid UTF sequences are silently discarded upon conversion. `str` has to be a valid string; passing null pointer results in undefined behavior. There are also two overloads with the same semantics which accept a string as an argument:
+
+[source]
+----
+std::string as_utf8(const std::wstring& str);
+std::wstring as_wide(const std::string& str);
+----
+
+[NOTE]
+====
+Most examples in this documentation assume char interface and therefore will not compile with [link PUGIXML_WCHAR_MODE]. This is done to simplify the documentation; usually the only changes you'll have to make is to pass `wchar_t` string literals, i.e. instead of
+
+`xml_node node = doc.child("bookstore").find_child_by_attribute("book", "id", "12345");`
+
+you'll have to do
+
+`xml_node node = doc.child(L"bookstore").find_child_by_attribute(L"book", L"id", L"12345");`
+====
+ 
+[[dom.thread]]
+=== Thread-safety guarantees
+
+Almost all functions in pugixml have the following thread-safety guarantees:
+
+* it is safe to call free (non-member) functions from multiple threads
+* it is safe to perform concurrent read-only accesses to the same tree (all constant member functions do not modify the tree)
+* it is safe to perform concurrent read/write accesses, if there is only one read or write access to the single tree at a time
+
+Concurrent modification and traversing of a single tree requires synchronization, for example via reader-writer lock. Modification includes altering document structure and altering individual node/attribute data, i.e. changing names/values.
+
+The only exception is [link set_memory_management_functions]; it modifies global variables and as such is not thread-safe. Its usage policy has more restrictions, see <<dom.memory.custom>>.
+
+[[dom.exception]]
+=== Exception guarantees
+
+With the exception of XPath, pugixml itself does not throw any exceptions. Additionally, most pugixml functions have a no-throw exception guarantee.
+
+This is not applicable to functions that operate on STL strings or IOstreams; such functions have either strong guarantee (functions that operate on strings) or basic guarantee (functions that operate on streams). Also functions that call user-defined callbacks (i.e. [link xml_node::traverse] or [link xml_node::find_node]) do not provide any exception guarantees beyond the ones provided by the callback.
+
+If exception handling is not disabled with [link PUGIXML_NO_EXCEPTIONS] define, XPath functions may throw [link xpath_exception] on parsing errors; also, XPath functions may throw `std::bad_alloc` in low memory conditions. Still, XPath functions provide strong exception guarantee.
+
+[[dom.memory]]
+=== Memory management
+
+pugixml requests the memory needed for document storage in big chunks, and allocates document data inside those chunks. This section discusses replacing functions used for chunk allocation and internal memory management implementation.
+
+[[dom.memory.custom]]
+==== Custom memory allocation/deallocation functions
+
+[#allocation_function]
+[#deallocation_function]
+All memory for tree structure, tree data and XPath objects is allocated via globally specified functions, which default to malloc/free. You can set your own allocation functions with set_memory_management function. The function interfaces are the same as that of malloc/free:
+
+[source]
+----
+typedef void* (*allocation_function)(size_t size);
+typedef void (*deallocation_function)(void* ptr);
+----
+
+[#set_memory_management_functions]
+[#get_memory_allocation_function]
+[#get_memory_deallocation_function]
+You can use the following accessor functions to change or get current memory management functions:
+
+[source]
+----
+void set_memory_management_functions(allocation_function allocate, deallocation_function deallocate);
+allocation_function get_memory_allocation_function();
+deallocation_function get_memory_deallocation_function();
+----
+
+Allocation function is called with the size (in bytes) as an argument and should return a pointer to a memory block with alignment that is suitable for storage of primitive types (usually a maximum of `void*` and `double` types alignment is sufficient) and size that is greater than or equal to the requested one. If the allocation fails, the function has to return null pointer (throwing an exception from allocation function results in undefined behavior).
+
+Deallocation function is called with the pointer that was returned by some call to allocation function; it is never called with a null pointer. If memory management functions are not thread-safe, library thread safety is not guaranteed.
+
+This is a simple example of custom memory management (link:samples/custom_memory_management.cpp[]):
+
+[source,indent=0]
+----
+include::samples/custom_memory_management.cpp[tags=decl] 
+----
+[source,indent=0]
+----
+include::samples/custom_memory_management.cpp[tags=call] 
+----
+
+When setting new memory management functions, care must be taken to make sure that there are no live pugixml objects. Otherwise when the objects are destroyed, the new deallocation function will be called with the memory obtained by the old allocation function, resulting in undefined behavior.
+
+[[dom.memory.tuning]]
+==== Memory consumption tuning
+
+There are several important buffering optimizations in pugixml that rely on predefined constants. These constants have default values that were tuned for common usage patterns; for some applications, changing these constants might improve memory consumption or increase performance. Changing these constants is not recommended unless their default values result in visible problems.
+
+These constants can be tuned via configuration defines, as discussed in <<install.building.config>>; it is recommended to set them in `pugiconfig.hpp`.
+
+* `PUGIXML_MEMORY_PAGE_SIZE` controls the page size for document memory allocation. Memory for node/attribute objects is allocated in pages of the specified size. The default size is 32 Kb; for some applications the size is too large (i.e. embedded systems with little heap space or applications that keep lots of XML documents in memory). A minimum size of 1 Kb is recommended.
+[lbr]
+
+* `PUGIXML_MEMORY_OUTPUT_STACK` controls the cumulative stack space required to output the node. Any output operation (i.e. saving a subtree to file) uses an internal buffering scheme for performance reasons. The default size is 10 Kb; if you're using node output from threads with little stack space, decreasing this value can prevent stack overflows. A minimum size of 1 Kb is recommended.
+[lbr]
+
+* `PUGIXML_MEMORY_XPATH_PAGE_SIZE` controls the page size for XPath memory allocation. Memory for XPath query objects as well as internal memory for XPath evaluation is allocated in pages of the specified size. The default size is 4 Kb; if you have a lot of resident XPath query objects, you might need to decrease the size to improve memory consumption. A minimum size of 256 bytes is recommended.
+
+[[dom.memory.internals]]
+==== Document memory management internals
+
+Constructing a document object using the default constructor does not result in any allocations; document node is stored inside the [link xml_document] object.
+
+When the document is loaded from file/buffer, unless an inplace loading function is used (see <<loading.memory>>), a complete copy of character stream is made; all names/values of nodes and attributes are allocated in this buffer. This buffer is allocated via a single large allocation and is only freed when document memory is reclaimed (i.e. if the [link xml_document] object is destroyed or if another document is loaded in the same object). Also when loading from file or stream, an additional large allocation may be performed if encoding conversion is required; a temporary buffer is allocated, and it is freed before load function returns.
+
+All additional memory, such as memory for document structure (node/attribute objects) and memory for node/attribute names/values is allocated in pages on the order of 32 kilobytes; actual objects are allocated inside the pages using a memory management scheme optimized for fast allocation/deallocation of many small objects. Because of the scheme specifics, the pages are only destroyed if all objects inside them are destroyed; also, generally destroying an object does not mean that subsequent object creation will reuse the same memory. This means that it is possible to devise a usage scheme which will lead to higher memory usage than expected; one example is adding a lot of nodes, and them removing all even numbered ones; not a single page is reclaimed in the process. However this is an example specifically crafted to produce unsatisfying behavior; in all practical usage scenarios the memory consumption is less than that of a general-purpose allocator because allocation meta-data is very small in size.
+
+[[loading]]
+== Loading document
+
+pugixml provides several functions for loading XML data from various places - files, C{plus}{plus} iostreams, memory buffers. All functions use an extremely fast non-validating parser. This parser is not fully W3C conformant - it can load any valid XML document, but does not perform some well-formedness checks. While considerable effort is made to reject invalid XML documents, some validation is not performed for performance reasons. Also some XML transformations (i.e. EOL handling or attribute value normalization) can impact parsing speed and thus can be disabled. However for vast majority of XML documents there is no performance difference between different parsing options. Parsing options also control whether certain XML nodes are parsed; see <<loading.options>> for more information.
+
+XML data is always converted to internal character format (see <<dom.unicode>>) before parsing. pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it's a strict subset of UTF-16) and handles all encoding conversions automatically. Unless explicit encoding is specified, loading functions perform automatic encoding detection based on first few characters of XML data, so in almost all cases you do not have to specify document encoding. Encoding conversion is described in more detail in <<loading.encoding>>.
+
+[[loading.file]]
+=== Loading document from file
+
+[#xml_document::load_file]
+[#xml_document::load_file_wide]
+The most common source of XML data is files; pugixml provides dedicated functions for loading an XML document from file:
+
+[source]
+----
+xml_parse_result xml_document::load_file(const char* path, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
+xml_parse_result xml_document::load_file(const wchar_t* path, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
+----
+    
+These functions accept the file path as its first argument, and also two optional arguments, which specify parsing options (see <<loading.options>>) and input data encoding (see <<loading.encoding>>). The path has the target operating system format, so it can be a relative or absolute one, it should have the delimiters of the target system, it should have the exact case if the target file system is case-sensitive, etc.
+
+File path is passed to the system file opening function as is in case of the first function (which accepts `const char* path`); the second function either uses a special file opening function if it is provided by the runtime library or converts the path to UTF-8 and uses the system file opening function.
+
+`load_file` destroys the existing document tree and then tries to load the new tree from the specified file. The result of the operation is returned in an [link xml_parse_result] object; this object contains the operation status and the related information (i.e. last successfully parsed position in the input file, if parsing fails). See <<loading.errors>> for error handling details.
+
+This is an example of loading XML document from file (link:samples/load_file.cpp[]):
+
+[source,indent=0]
+----
+include::samples/load_file.cpp[tags=code] 
+----
+
+[[loading.memory]]
+=== Loading document from memory
+
+[#xml_document::load_buffer]
+[#xml_document::load_buffer_inplace]
+[#xml_document::load_buffer_inplace_own]
+Sometimes XML data should be loaded from some other source than a file, i.e. HTTP URL; also you may want to load XML data from file using non-standard functions, i.e. to use your virtual file system facilities or to load XML from gzip-compressed files. All these scenarios require loading document from memory. First you should prepare a contiguous memory block with all XML data; then you have to invoke one of buffer loading functions. These functions will handle the necessary encoding conversions, if any, and then will parse the data into the corresponding XML tree. There are several buffer loading functions, which differ in the behavior and thus in performance/memory usage:
+
+[source]
+----
+xml_parse_result xml_document::load_buffer(const void* contents, size_t size, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
+xml_parse_result xml_document::load_buffer_inplace(void* contents, size_t size, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
+xml_parse_result xml_document::load_buffer_inplace_own(void* contents, size_t size, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
+----
+
+All functions accept the buffer which is represented by a pointer to XML data, `contents`, and data size in bytes. Also there are two optional arguments, which specify parsing options (see <<loading.options>>) and input data encoding (see <<loading.encoding>>). The buffer does not have to be zero-terminated.
+
+`load_buffer` function works with immutable buffer - it does not ever modify the buffer. Because of this restriction it has to create a private buffer and copy XML data to it before parsing (applying encoding conversions if necessary). This copy operation carries a performance penalty, so inplace functions are provided - `load_buffer_inplace` and `load_buffer_inplace_own` store the document data in the buffer, modifying it in the process. In order for the document to stay valid, you have to make sure that the buffer's lifetime exceeds that of the tree if you're using inplace functions. In addition to that, `load_buffer_inplace` does not assume ownership of the buffer, so you'll have to destroy it yourself; `load_buffer_inplace_own` assumes ownership of the buffer and destroys it once it is not needed. This means that if you're using `load_buffer_inplace_own`, you have to allocate memory with pugixml allocation function (you can get it via [link get_memory_allocation_function]).
+
+The best way from the performance/memory point of view is to load document using `load_buffer_inplace_own`; this function has maximum control of the buffer with XML data so it is able to avoid redundant copies and reduce peak memory usage while parsing. This is the recommended function if you have to load the document from memory and performance is critical.
+
+[#xml_document::load_string]
+There is also a simple helper function for cases when you want to load the XML document from null-terminated character string:
+
+[source]
+----
+xml_parse_result xml_document::load_string(const char_t* contents, unsigned int options = parse_default);
+----
+
+It is equivalent to calling `load_buffer` with `size` being either `strlen(contents)` or `wcslen(contents) * sizeof(wchar_t)`, depending on the character type. This function assumes native encoding for input data, so it does not do any encoding conversion. In general, this function is fine for loading small documents from string literals, but has more overhead and less functionality than the buffer loading functions.
+
+This is an example of loading XML document from memory using different functions (link:samples/load_memory.cpp[]):

+[[loading.stream]]
+=== Loading document from C{plus}{plus} IOstreams
+
+[#xml_document::load_stream]
+To enhance interoperability, pugixml provides functions for loading document from any object which implements C{plus}{plus} `std::istream` interface. This allows you to load documents from any standard C{plus}{plus} stream (i.e. file stream) or any third-party compliant implementation (i.e. Boost Iostreams). There are two functions, one works with narrow character streams, another handles wide character ones:
+
+[source]

+xml_parse_result xml_document::load(std::wistream& stream, unsigned int options = parse_default);
+----
+
+`load` with `std::istream` argument loads the document from stream from the current read position to the end, treating the stream contents as a byte stream of the specified encoding (with encoding autodetection as necessary). Thus calling `xml_document::load` on an opened `std::ifstream` object is equivalent to calling `xml_document::load_file`.
+
+`load` with `std::wstream` argument treats the stream contents as a wide character stream (encoding is always [link encoding_wchar]). Because of this, using `load` with wide character streams requires careful (usually platform-specific) stream setup (i.e. using the `imbue` function). Generally use of wide streams is discouraged, however it provides you the ability to load documents from non-Unicode encodings, i.e. you can load Shift-JIS encoded data if you set the correct locale.
+
+This is a simple example of loading XML document from file using streams (link:samples/load_stream.cpp[]); read the sample code for more complex examples involving wide streams and locales:

+[[loading.errors]]
+=== Handling parsing errors
+
+[#xml_parse_result]
+All document loading functions return the parsing result via `xml_parse_result` object. It contains parsing status, the offset of last successfully parsed character from the beginning of the source stream, and the encoding of the source stream:
+
+[source]
+----
+struct xml_parse_result
+{
+    xml_parse_status status;
+    ptrdiff_t offset;
+    xml_encoding encoding;
+
+    operator bool() const;
+    const char* description() const;
+};
+----
+
+[#xml_parse_status]
+[#xml_parse_result::status]
+Parsing status is represented as the `xml_parse_status` enumeration and can be one of the following:
+
+* [anchor status_ok] means that no error was encountered during parsing; the source stream represents the valid XML document which was fully parsed and converted to a tree.
+[lbr]
+
+* [anchor status_file_not_found] is only returned by `load_file` function and means that file could not be opened.
+* [anchor status_io_error] is returned by `load_file` function and by `load` functions with `std::istream`/`std::wstream` arguments; it means that some I/O error has occurred during reading the file/stream.
+* [anchor status_out_of_memory] means that there was not enough memory during some allocation; any allocation failure during parsing results in this error.
+* [anchor status_internal_error] means that something went horribly wrong; currently this error does not occur
+[lbr]
+
+* [anchor status_unrecognized_tag] means that parsing stopped due to a tag with either an empty name or a name which starts with incorrect character, such as [^#].
+* [anchor status_bad_pi] means that parsing stopped due to incorrect document declaration/processing instruction
+* [anchor status_bad_comment], [anchor status_bad_cdata], [anchor status_bad_doctype] and [anchor status_bad_pcdata] mean that parsing stopped due to the invalid construct of the respective type
+* [anchor status_bad_start_element] means that parsing stopped because starting tag either had no closing `>` symbol or contained some incorrect symbol
+* [anchor status_bad_attribute] means that parsing stopped because there was an incorrect attribute, such as an attribute without value or with value that is not quoted (note that `<node attr=1>` is incorrect in XML)
+* [anchor status_bad_end_element] means that parsing stopped because ending tag had incorrect syntax (i.e. extra non-whitespace symbols between tag name and `>`)
+* [anchor status_end_element_mismatch] means that parsing stopped because the closing tag did not match the opening one (i.e. `<node></nedo>`) or because some tag was not closed at all
+* [anchor status_no_document_element] means that no element nodes were discovered during parsing; this usually indicates an empty or invalid document
+
+[#xml_parse_result::description]
+`description()` member function can be used to convert parsing status to a string; the returned message is always in English, so you'll have to write your own function if you need a localized string. However please note that the exact messages returned by `description()` function may change from version to version, so any complex status handling should be based on `status` value. Note that `description()` returns a `char` string even in `PUGIXML_WCHAR_MODE`; you'll have to call [link as_wide] to get the `wchar_t` string.
+
+If parsing failed because the source data was not a valid XML, the resulting tree is not destroyed - despite the fact that load function returns error, you can use the part of the tree that was successfully parsed. Obviously, the last element may have an unexpected name/value; for example, if the attribute value does not end with the necessary quotation mark, like in [^<node attr="value>some data</node>] example, the value of attribute `attr` will contain the string `value>some data</node>`.
+
+[#xml_parse_result::offset]
+In addition to the status code, parsing result has an `offset` member, which contains the offset of last successfully parsed character if parsing failed because of an error in source data; otherwise `offset` is 0. For parsing efficiency reasons, pugixml does not track the current line during parsing; this offset is in units of [link char_t pugi::char_t] (bytes for character mode, wide characters for wide character mode). Many text editors support 'Go To Position' feature - you can use it to locate the exact error position. Alternatively, if you're loading the document from memory, you can display the error chunk along with the error description (see the example code below).
+
+CAUTION: Offset is calculated in the XML buffer in native encoding; if encoding conversion is performed during parsing, offset can not be used to reliably track the error position.
+
+[#xml_parse_result::encoding]
+Parsing result also has an `encoding` member, which can be used to check that the source data encoding was correctly guessed. It is equal to the exact encoding used during parsing (i.e. with the exact endianness); see <<loading.encoding>> for more information.
+
+[#xml_parse_result::bool]
+Parsing result object can be implicitly converted to `bool`; if you do not want to handle parsing errors thoroughly, you can just check the return value of load functions as if it was a `bool`: `if (doc.load_file("file.xml")) { ... } else { ... }`.
+
+This is an example of handling loading errors (link:samples/load_error_handling.cpp[]):

+include::samples/load_error_handling.cpp[tags=code] 
+----
+
+[[loading.options]]
+=== Parsing options
+
+All document loading functions accept the optional parameter `options`. This is a bitmask that customizes the parsing process: you can select the node types that are parsed and various transformations that are performed with the XML text. Disabling certain transformations can improve parsing performance for some documents; however, the code for all transformations is very well optimized, and thus the majority of documents won't get any performance benefit. As a rule of thumb, only modify parsing flags if you want to get some nodes in the document that are excluded by default (i.e. declaration or comment nodes).
+
+NOTE: You should use the usual bitwise arithmetics to manipulate the bitmask: to enable a flag, use `mask | flag`; to disable a flag, use `mask & ~flag`.
+
+These flags control the resulting tree contents:
+
+* [anchor parse_declaration] determines if XML document declaration (node with type [link node_declaration]) is to be put in DOM tree. If this flag is off, it is not put in the tree, but is still parsed and checked for correctness. This flag is *off* by default.
+[lbr]
+
+* [anchor parse_doctype] determines if XML document type declaration (node with type [link node_doctype]) is to be put in DOM tree. If this flag is off, it is not put in the tree, but is still parsed and checked for correctness. This flag is *off* by default.
+[lbr]
+
+* [anchor parse_pi] determines if processing instructions (nodes with type [link node_pi]) are to be put in DOM tree. If this flag is off, they are not put in the tree, but are still parsed and checked for correctness. Note that `<?xml ...?>` (document declaration) is not considered to be a PI. This flag is *off* by default.
+[lbr]
+
+* [anchor parse_comments] determines if comments (nodes with type [link node_comment]) are to be put in DOM tree. If this flag is off, they are not put in the tree, but are still parsed and checked for correctness. This flag is *off* by default.
+[lbr]
+
+* [anchor parse_cdata] determines if CDATA sections (nodes with type [link node_cdata]) are to be put in DOM tree. If this flag is off, they are not put in the tree, but are still parsed and checked for correctness. This flag is *on* by default.
+[lbr]
+
+* [anchor parse_trim_pcdata] determines if leading and trailing whitespace characters are to be removed from PCDATA nodes. While for some applications leading/trailing whitespace is significant, often the application only cares about the non-whitespace contents so it's easier to trim whitespace from text during parsing. This flag is *off* by default.
+[lbr]
+
+* [anchor parse_ws_pcdata] determines if PCDATA nodes (nodes with type [link node_pcdata]) that consist only of whitespace characters are to be put in DOM tree. Often whitespace-only data is not significant for the application, and the cost of allocating and storing such nodes (both memory and speed-wise) can be significant. For example, after parsing XML string `<node> <a/> </node>`, `<node>` element will have three children when `parse_ws_pcdata` is set (child with type [link node_pcdata] and value `" "`, child with type [link node_element] and name `"a"`, and another child with type [link node_pcdata] and value `" "`), and only one child when `parse_ws_pcdata` is not set. This flag is *off* by default.
+[lbr]
+
+* [anchor parse_ws_pcdata_single] determines if whitespace-only PCDATA nodes that have no sibling nodes are to be put in DOM tree. In some cases application needs to parse the whitespace-only contents of nodes, i.e. `<node>  </node>`, but is not interested in whitespace markup elsewhere. It is possible to use [link parse_ws_pcdata] flag in this case, but it results in excessive allocations and complicates document processing in some cases; this flag is intended to avoid that. As an example, after parsing XML string `<node> <a>  </a> </node>` with `parse_ws_pcdata_single` flag set, `<node>` element will have one child `<a>`, and `<a>` element will have one child with type [link node_pcdata] and value `"  "`. This flag has no effect if [link parse_ws_pcdata] is enabled. This flag is *off* by default.
+[lbr]
+
+* [anchor parse_fragment] determines if document should be treated as a fragment of a valid XML. Parsing document as a fragment leads to top-level PCDATA content (i.e. text that is not located inside a node) to be added to a tree, and additionally treats documents without element nodes as valid. This flag is *off* by default.
+
+CAUTION: Using in-place parsing ([link xml_document::load_buffer_inplace load_buffer_inplace]) with `parse_fragment` flag may result in the loss of the last character of the buffer if it is a part of PCDATA. Since PCDATA values are null-terminated strings, the only way to resolve this is to provide a null-terminated buffer as an input to `load_buffer_inplace` - i.e. `doc.load_buffer_inplace("test\0", 5, pugi::parse_default | pugi::parse_fragment)`.
+
+These flags control the transformation of tree element contents:
+
+* [anchor parse_escapes] determines if character and entity references are to be expanded during the parsing process. Character references have the form [^&#...;] or [^&#x...;] ([^...] is Unicode numeric representation of character in either decimal ([^&#...;]) or hexadecimal ([^&#x...;]) form), entity references are [^&lt;], [^&gt;], [^&amp;], [^&apos;] and [^&quot;] (note that as pugixml does not handle DTD, the only allowed entities are predefined ones). If character/entity reference can not be expanded, it is left as is, so you can do additional processing later. Reference expansion is performed on attribute values and PCDATA content. This flag is *on* by default.
+[lbr]
+
+* [anchor parse_eol] determines if EOL handling (that is, replacing sequences `0x0d 0x0a` by a single `0x0a` character, and replacing all standalone `0x0d` characters by `0x0a`) is to be performed on input data (that is, comments contents, PCDATA/CDATA contents and attribute values). This flag is *on* by default.
+[lbr]
+
+* [anchor parse_wconv_attribute] determines if attribute value normalization should be performed for all attributes. This means, that whitespace characters (new line, tab and space) are replaced with space (`' '`). New line characters are always treated as if [link parse_eol] is set, i.e. `\r\n` is converted to a single space.  This flag is *on* by default.
+[lbr]
+
+* [anchor parse_wnorm_attribute] determines if extended attribute value normalization should be performed for all attributes. This means, that after attribute values are normalized as if [link parse_wconv_attribute] was set, leading and trailing space characters are removed, and all sequences of space characters are replaced by a single space character. [link parse_wconv_attribute] has no effect if this flag is on. This flag is *off* by default.
+
+NOTE: `parse_wconv_attribute` option performs transformations that are required by W3C specification for attributes that are declared as [^CDATA]; [link parse_wnorm_attribute] performs transformations required for [^NMTOKENS] attributes. In the absence of document type declaration all attributes should behave as if they are declared as [^CDATA], thus [link parse_wconv_attribute] is the default option.
+
+Additionally there are three predefined option masks:
+
+* [anchor parse_minimal] has all options turned off. This option mask means that pugixml does not add declaration nodes, document type declaration nodes, PI nodes, CDATA sections and comments to the resulting tree and does not perform any conversion for input data, so theoretically it is the fastest mode. However, as mentioned above, in practice [link parse_default] is usually equally fast.
+[lbr]
+
+* [anchor parse_default] is the default set of flags, i.e. it has all options set to their default values. It includes parsing CDATA sections (comments/PIs are not parsed), performing character and entity reference expansion, replacing whitespace characters with spaces in attribute values and performing EOL handling. Note, that PCDATA sections consisting only of whitespace characters are not parsed (by default) for performance reasons.
+[lbr]
+
+* [anchor parse_full] is the set of flags which adds nodes of all types to the resulting tree and performs default conversions for input data. It includes parsing CDATA sections, comments, PI nodes, document declaration node and document type declaration node, performing character and entity reference expansion, replacing whitespace characters with spaces in attribute values and performing EOL handling. Note, that PCDATA sections consisting only of whitespace characters are not parsed in this mode.
+
+This is an example of using different parsing options (link:samples/load_options.cpp[]):

+
+[[loading.encodings]]
+=== Encodings
+
+[#xml_encoding]
+pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it's a strict subset of UTF-16) and handles all encoding conversions. Most loading functions accept the optional parameter `encoding`. This is a value of enumeration type `xml_encoding`, that can have the following values:
+
+* [anchor encoding_auto] means that pugixml will try to guess the encoding based on source XML data. The algorithm is a modified version of the one presented in Appendix F.1 of XML recommendation; it tries to match the first few bytes of input data with the following patterns in strict order:
+[lbr]
+    * If first four bytes match UTF-32 BOM (Byte Order Mark), encoding is assumed to be UTF-32 with the endianness equal to that of BOM;
+    * If first two bytes match UTF-16 BOM, encoding is assumed to be UTF-16 with the endianness equal to that of BOM;
+    * If first three bytes match UTF-8 BOM, encoding is assumed to be UTF-8;
+    * If first four bytes match UTF-32 representation of [^<], encoding is assumed to be UTF-32 with the corresponding endianness;
+    * If first four bytes match UTF-16 representation of [^<?], encoding is assumed to be UTF-16 with the corresponding endianness;
+    * If first two bytes match UTF-16 representation of [^<], encoding is assumed to be UTF-16 with the corresponding endianness (this guess may yield incorrect result, but it's better than UTF-8);
+    * Otherwise encoding is assumed to be UTF-8.
+    [lbr]
+
+* [anchor encoding_utf8] corresponds to UTF-8 encoding as defined in the Unicode standard; UTF-8 sequences with length equal to 5 or 6 are not standard and are rejected.
+* [anchor encoding_utf16_le] corresponds to little-endian UTF-16 encoding as defined in the Unicode standard; surrogate pairs are supported.
+* [anchor encoding_utf16_be] corresponds to big-endian UTF-16 encoding as defined in the Unicode standard; surrogate pairs are supported.
+* [anchor encoding_utf16] corresponds to UTF-16 encoding as defined in the Unicode standard; the endianness is assumed to be that of the target platform.
+* [anchor encoding_utf32_le] corresponds to little-endian UTF-32 encoding as defined in the Unicode standard.
+* [anchor encoding_utf32_be] corresponds to big-endian UTF-32 encoding as defined in the Unicode standard.
+* [anchor encoding_utf32] corresponds to UTF-32 encoding as defined in the Unicode standard; the endianness is assumed to be that of the target platform.
+* [anchor encoding_wchar] corresponds to the encoding of `wchar_t` type; it has the same meaning as either `encoding_utf16` or `encoding_utf32`, depending on `wchar_t` size.
+* [anchor encoding_latin1] corresponds to ISO-8859-1 encoding (also known as Latin-1).
+
+The algorithm used for `encoding_auto` correctly detects any supported Unicode encoding for all well-formed XML documents (since they start with document declaration) and for all other XML documents that start with [^<]; if your XML document does not start with [^<] and has encoding that is different from UTF-8, use the specific encoding.
+
+NOTE: The current behavior for Unicode conversion is to skip all invalid UTF sequences during conversion. This behavior should not be relied upon; moreover, in case no encoding conversion is performed, the invalid sequences are not removed, so you'll get them as is in node/attribute contents.
+
+[[loading.w3c]]
+=== Conformance to W3C specification
+
+pugixml is not fully W3C conformant - it can load any valid XML document, but does not perform some well-formedness checks. While considerable effort is made to reject invalid XML documents, some validation is not performed because of performance reasons.
+
+There is only one non-conformant behavior when dealing with valid XML documents: pugixml does not use information supplied in document type declaration for parsing. This means that entities declared in DOCTYPE are not expanded, and all attribute/PCDATA values are always processed in a uniform way that depends only on parsing options.
+
+As for rejecting invalid XML documents, there are a number of incompatibilities with W3C specification, including:
+
+* Multiple attributes of the same node can have equal names.
+* All non-ASCII characters are treated in the same way as symbols of English alphabet, so some invalid tag names are not rejected.
+* Attribute values which contain [^<] are not rejected.
+* Invalid entity/character references are not rejected and are instead left as is.
+* Comment values can contain [^--].
+* XML data is not required to begin with document declaration; additionally, document declaration can appear after comments and other nodes.
+* Invalid document type declarations are silently ignored in some cases.
+
+[[access]]
+== Accessing document data
+
+pugixml features an extensive interface for getting various types of data from the document and for traversing the document. This section provides documentation for all such functions that do not modify the tree except for XPath-related functions; see <<xpath>> for XPath reference. As discussed in <<dom.cpp>>, there are two types of handles to tree data - [link xml_node] and [link xml_attribute]. The handles have special null (empty) values which propagate through various functions and thus are useful for writing more concise code; see [link node_null this description] for details. The documentation in this section will explicitly state the results of all function in case of null inputs.
+
+[import samples/traverse_base.cpp]
+
+[[access.basic]]
+=== Basic traversal functions
+
+[#xml_node::parent][#xml_node::first_child][#xml_node::last_child][#xml_node::next_sibling][#xml_node::previous_sibling][#xml_node::first_attribute][#xml_node::last_attribute][#xml_attribute::next_attribute][#xml_attribute::previous_attribute]
+The internal representation of the document is a tree, where each node has a list of child nodes (the order of children corresponds to their order in the XML representation), and additionally element nodes have a list of attributes, which is also ordered. Several functions are provided in order to let you get from one node in the tree to the other. These functions roughly correspond to the internal representation, and thus are usually building blocks for other methods of traversing (i.e. XPath traversals are based on these functions).
+ 
+[source]
+----
+xml_node xml_node::parent() const;
+xml_node xml_node::first_child() const;
+xml_node xml_node::last_child() const;
+xml_node xml_node::next_sibling() const;
+xml_node xml_node::previous_sibling() const;
+
+xml_attribute xml_node::first_attribute() const;
+xml_attribute xml_node::last_attribute() const;
+xml_attribute xml_attribute::next_attribute() const;
+xml_attribute xml_attribute::previous_attribute() const;
+----
+
+`parent` function returns the node's parent; all non-null nodes except the document have non-null parent. `first_child` and `last_child` return the first and last child of the node, respectively; note that only document nodes and element nodes can have non-empty child node list. If node has no children, both functions return null nodes. `next_sibling` and `previous_sibling` return the node that's immediately to the right/left of this node in the children list, respectively - for example, in `<a/><b/><c/>`, calling `next_sibling` for a handle that points to `<b/>` results in a handle pointing to `<c/>`, and calling `previous_sibling` results in handle pointing to `<a/>`. If node does not have next/previous sibling (this happens if it is the last/first node in the list, respectively), the functions return null nodes. `first_attribute`, `last_attribute`, `next_attribute` and `previous_attribute` functions behave similarly to the corresponding child node functions and allow to iterate through attribute list in the same way.
+
+NOTE: Because of memory consumption reasons, attributes do not have a link to their parent nodes. Thus there is no `xml_attribute::parent()` function.
+
+Calling any of the functions above on the null handle results in a null handle - i.e. `node.first_child().next_sibling()` returns the second child of `node`, and null handle if `node` is null, has no children at all or if it has only one child node.
+
+With these functions, you can iterate through all child nodes and display all attributes like this (link:samples/traverse_base.cpp[]):
+
+[source,indent=0]

+include::samples/traverse_base.cpp[tags=basic] 
+----
+
+[[access.nodedata]]
+=== Getting node data
+
+[#xml_node::name][#xml_node::value]
+Apart from structural information (parent, child nodes, attributes), nodes can have name and value, both of which are strings. Depending on node type, name or value may be absent. [link node_document] nodes do not have a name or value, [link node_element] and [link node_declaration] nodes always have a name but never have a value, [link node_pcdata], [link node_cdata], [link node_comment] and [link node_doctype] nodes never have a name but always have a value (it may be empty though), [link node_pi] nodes always have a name and a value (again, value may be empty). In order to get node's name or value, you can use the following functions:
+
+[source]
+----
+const char_t* xml_node::name() const;
+const char_t* xml_node::value() const;
+----
+
+In case node does not have a name or value or if the node handle is null, both functions return empty strings - they never return null pointers.
+
+[#xml_node::child_value]
+It is common to store data as text contents of some node - i.e. `<node><description>This is a node</description></node>`. In this case, `<description>` node does not have a value, but instead has a child of type [link node_pcdata] with value `"This is a node"`. pugixml provides several helper functions to parse such data:
+
+[source]
+----
+const char_t* xml_node::child_value() const;
+const char_t* xml_node::child_value(const char_t* name) const;
+xml_text xml_node::text() const;
+----
+
+`child_value()` returns the value of the first child with type [link node_pcdata] or [link node_cdata]; `child_value(name)` is a simple wrapper for `child(name).child_value()`. For the above example, calling `node.child_value("description")` and `description.child_value()` will both produce string `"This is a node"`. If there is no child with relevant type, or if the handle is null, `child_value` functions return empty string.
+
+`text()` returns a special object that can be used for working with PCDATA contents in more complex cases than just retrieving the value; it is described in <<access.text>> sections.
+
+There is an example of using some of these functions [link code_traverse_base_data at the end of the next section].
+
+[[access.attrdata]]
+=== Getting attribute data
+
+[#xml_attribute::name][#xml_attribute::value]
+All attributes have name and value, both of which are strings (value may be empty). There are two corresponding accessors, like for `xml_node`:
+
+[source]
+----
+const char_t* xml_attribute::name() const;
+const char_t* xml_attribute::value() const;
+----
+
+In case the attribute handle is null, both functions return empty strings - they never return null pointers.
+
+[#xml_attribute::as_string]
+If you need a non-empty string if the attribute handle is null (for example, you need to get the option value from XML attribute, but if it is not specified, you need it to default to `"sorted"` instead of `""`), you can use `as_string` accessor:
+
+[source]
+----
+const char_t* xml_attribute::as_string(const char_t* def = "") const;
+----
+
+It returns `def` argument if the attribute handle is null. If you do not specify the argument, the function is equivalent to `value()`.
+
+[#xml_attribute::as_int][#xml_attribute::as_uint][#xml_attribute::as_double][#xml_attribute::as_float][#xml_attribute::as_bool][#xml_attribute::as_llong][#xml_attribute::as_ullong]
+In many cases attribute values have types that are not strings - i.e. an attribute may always contain values that should be treated as integers, despite the fact that they are represented as strings in XML. pugixml provides several accessors that convert attribute value to some other type:
+ 
+[source]
+----
+int xml_attribute::as_int(int def = 0) const;
+unsigned int xml_attribute::as_uint(unsigned int def = 0) const;
+double xml_attribute::as_double(double def = 0) const;
+float xml_attribute::as_float(float def = 0) const;
+bool xml_attribute::as_bool(bool def = false) const;
+long long xml_attribute::as_llong(long long def = 0) const;
+unsigned long long xml_attribute::as_ullong(unsigned long long def = 0) const;
+----
+
+`as_int`, `as_uint`, `as_llong`, `as_ullong`, `as_double` and `as_float` convert attribute values to numbers. If attribute handle is null or attribute value is empty, `def` argument is returned (which is 0 by default). Otherwise, all leading whitespace characters are truncated, and the remaining string is parsed as an integer number in either decimal or hexadecimal form (applicable to `as_int`, `as_uint`, `as_llong` and `as_ullong`; hexadecimal format is used if the number has `0x` or `0X` prefix) or as a floating point number in either decimal or scientific form (`as_double` or `as_float`). Any extra characters are silently discarded, i.e. `as_int` will return `1` for string `"1abc"`.
+
+In case the input string contains a number that is out of the target numeric range, the result is undefined.
+
+CAUTION: Number conversion functions depend on current C locale as set with `setlocale`, so may return unexpected results if the locale is different from `"C"`.
+
+`as_bool` converts attribute value to boolean as follows: if attribute handle is null, `def` argument is returned (which is `false` by default). If attribute value is empty, `false` is returned. Otherwise, `true` is returned if the first character is one of `'1', 't', 'T', 'y', 'Y'`. This means that strings like `"true"` and `"yes"` are recognized as `true`, while strings like `"false"` and `"no"` are recognized as `false`. For more complex matching you'll have to write your own function.
+
+NOTE: `as_llong` and `as_ullong` are only available if your platform has reliable support for the `long long` type, including string conversions.

+
+[#xml_node::child][#xml_node::attribute][#xml_node::next_sibling_name][#xml_node::previous_sibling_name]
+Since a lot of document traversal consists of finding the node/attribute with the correct name, there are special functions for that purpose:
+
+[source]
+----
+xml_node xml_node::child(const char_t* name) const;
+xml_attribute xml_node::attribute(const char_t* name) const;
+xml_node xml_node::next_sibling(const char_t* name) const;
+xml_node xml_node::previous_sibling(const char_t* name) const;
+----
+
+`child` and `attribute` return the first child/attribute with the specified name; `next_sibling` and `previous_sibling` return the first sibling in the corresponding direction with the specified name. All string comparisons are case-sensitive. In case the node handle is null or there is no node/attribute with the specified name, null handle is returned.
+
+`child` and `next_sibling` functions can be used together to loop through all child nodes with the desired name like this:
+
+[source]
+----
+for (pugi::xml_node tool = tools.child("Tool"); tool; tool = tool.next_sibling("Tool"))
+----
+
+[#xml_node::find_child_by_attribute]
+Occasionally the needed node is specified not by the unique name but instead by the value of some attribute; for example, it is common to have node collections with each node having a unique id: `<group><item id="1"/> <item id="2"/></group>`. There are two functions for finding child nodes based on the attribute values:
+
+[source]
+----
+xml_node xml_node::find_child_by_attribute(const char_t* name, const char_t* attr_name, const char_t* attr_value) const;
+xml_node xml_node::find_child_by_attribute(const char_t* attr_name, const char_t* attr_value) const;
+----
+
+The three-argument function returns the first child node with the specified name which has an attribute with the specified name/value; the two-argument function skips the name test for the node, which can be useful for searching in heterogeneous collections. If the node handle is null or if no node is found, null handle is returned. All string comparisons are case-sensitive.
+
+In all of the above functions, all arguments have to be valid strings; passing null pointers results in undefined behavior.
+
+This is an example of using these functions (link:samples/traverse_base.cpp[]):

+[[access.rangefor]]
+=== Range-based for-loop support
+
+[#xml_node::children][#xml_node::attributes]
+If your C{plus}{plus} compiler supports range-based for-loop (this is a C{plus}{plus}11 feature, at the time of writing it's supported by Microsoft Visual Studio 11 Beta, GCC 4.6 and Clang 3.0), you can use it to enumerate nodes/attributes. Additional helpers are provided to support this; note that they are also compatible with http://www.boost.org/libs/foreach/[Boost Foreach], and possibly other pre-C{plus}{plus}11 foreach facilities.
+
+[source]

+``/implementation-defined type/`` xml_node::children() const;
+``/implementation-defined type/`` xml_node::children(const char_t* name) const;
+``/implementation-defined type/`` xml_node::attributes() const;
+----
+
+`children` function allows you to enumerate all child nodes; `children` function with `name` argument allows you to enumerate all child nodes with a specific name; `attributes` function allows you to enumerate all attributes of the node. Note that you can also use node object itself in a range-based for construct, which is equivalent to using `children()`.

+[[access.iterators]]
+=== Traversing node/attribute lists via iterators
+
+[#xml_node_iterator][#xml_attribute_iterator][#xml_node::begin][#xml_node::end][#xml_node::attributes_begin][#xml_node::attributes_end]
+Child node lists and attribute lists are simply double-linked lists; while you can use `previous_sibling`/`next_sibling` and other such functions for iteration, pugixml additionally provides node and attribute iterators, so that you can treat nodes as containers of other nodes or attributes:
+
+[source]
+----
+class xml_node_iterator;
+class xml_attribute_iterator;
+
+typedef xml_node_iterator xml_node::iterator;
+iterator xml_node::begin() const;
+iterator xml_node::end() const;
+
+typedef xml_attribute_iterator xml_node::attribute_iterator;
+attribute_iterator xml_node::attributes_begin() const;
+attribute_iterator xml_node::attributes_end() const;
+----
+
+`begin` and `attributes_begin` return iterators that point to the first node/attribute, respectively; `end` and `attributes_end` return past-the-end iterator for node/attribute list, respectively - this iterator can't be dereferenced, but decrementing it results in an iterator pointing to the last element in the list (except for empty lists, where decrementing past-the-end iterator results in undefined behavior). Past-the-end iterator is commonly used as a termination value for iteration loops (see sample below). If you want to get an iterator that points to an existing handle, you can construct the iterator with the handle as a single constructor argument, like so: `xml_node_iterator(node)`. For `xml_attribute_iterator`, you'll have to provide both an attribute and its parent node.
+
+`begin` and `end` return equal iterators if called on null node; such iterators can't be dereferenced. `attributes_begin` and `attributes_end` behave the same way. For correct iterator usage this means that child node/attribute collections of null nodes appear to be empty.
+
+Both types of iterators have bidirectional iterator semantics (i.e. they can be incremented and decremented, but efficient random access is not supported) and support all usual iterator operations - comparison, dereference, etc. The iterators are invalidated if the node/attribute objects they're pointing to are removed from the tree; adding nodes/attributes does not invalidate any iterators.
+
+Here is an example of using iterators for document traversal (link:samples/traverse_iter.cpp[]):
+
+[source,indent=0]
+----
+include::samples/traverse_iter.cpp[tags=code] 
+----
+
+CAUTION: Node and attribute iterators are somewhere in the middle between const and non-const iterators. While dereference operation yields a non-constant reference to the object, so that you can use it for tree modification operations, modifying this reference by assignment - i.e. passing iterators to a function like `std::sort` - will not give expected results, as assignment modifies local handle that's stored in the iterator.
+
+[[access.walker]]
+=== Recursive traversal with xml_tree_walker
+
+[#xml_tree_walker]
+The methods described above allow traversal of immediate children of some node; if you want to do a deep tree traversal, you'll have to do it via a recursive function or some equivalent method. However, pugixml provides a helper for depth-first traversal of a subtree. In order to use it, you have to implement `xml_tree_walker` interface and to call `traverse` function:
+
+[source]
+----
+class xml_tree_walker
+{
+public:
+    virtual bool begin(xml_node& node);
+    virtual bool for_each(xml_node& node) = 0;
+    virtual bool end(xml_node& node);
+
+    int depth() const;
+};
+
+bool xml_node::traverse(xml_tree_walker& walker);
+----
+
+[#xml_tree_walker::begin][#xml_tree_walker::for_each][#xml_tree_walker::end][#xml_node::traverse]
+The traversal is launched by calling `traverse` function on traversal root and proceeds as follows:
+
+* First, `begin` function is called with traversal root as its argument.
+* Then, `for_each` function is called for all nodes in the traversal subtree in depth first order, excluding the traversal root. Node is passed as an argument.
+* Finally, `end` function is called with traversal root as its argument.
+
+If `begin`, `end` or any of the `for_each` calls return `false`, the traversal is terminated and `false` is returned as the traversal result; otherwise, the traversal results in `true`. Note that you don't have to override `begin` or `end` functions; their default implementations return `true`.
+
+[#xml_tree_walker::depth]
+You can get the node's depth relative to the traversal root at any point by calling `depth` function. It returns `-1` if called from `begin`/`end`, and returns 0-based depth if called from `for_each` - depth is 0 for all children of the traversal root, 1 for all grandchildren and so on.
+
+This is an example of traversing tree hierarchy with xml_tree_walker (link:samples/traverse_walker.cpp[]):

+[[access.predicate]]
+=== Searching for nodes/attributes with predicates
+
+[#xml_node::find_attribute][#xml_node::find_child][#xml_node::find_node]
+While there are existing functions for getting a node/attribute with known contents, they are often not sufficient for simple queries. As an alternative for manual iteration through nodes/attributes until the needed one is found, you can make a predicate and call one of `find_` functions:
+
+[source]
+----
+template <typename Predicate> xml_attribute xml_node::find_attribute(Predicate pred) const;
+template <typename Predicate> xml_node xml_node::find_child(Predicate pred) const;
+template <typename Predicate> xml_node xml_node::find_node(Predicate pred) const;
+----
+
+The predicate should be either a plain function or a function object which accepts one argument of type `xml_attribute` (for `find_attribute`) or `xml_node` (for `find_child` and `find_node`), and returns `bool`. The predicate is never called with null handle as an argument.
+
+`find_attribute` function iterates through all attributes of the specified node, and returns the first attribute for which the predicate returned `true`. If the predicate returned `false` for all attributes or if there were no attributes (including the case where the node is null), null attribute is returned.
+
+`find_child` function iterates through all child nodes of the specified node, and returns the first node for which the predicate returned `true`. If the predicate returned `false` for all nodes or if there were no child nodes (including the case where the node is null), null node is returned.
+
+`find_node` function performs a depth-first traversal through the subtree of the specified node (excluding the node itself), and returns the first node for which the predicate returned `true`. If the predicate returned `false` for all nodes or if subtree was empty, null node is returned.
+
+This is an example of using predicate-based functions (link:samples/traverse_predicate.cpp[]):

+
+[[access.text]]
+=== Working with text contents
+
+[#xml_text]
+It is common to store data as text contents of some node - i.e. `<node><description>This is a node</description></node>`. In this case, `<description>` node does not have a value, but instead has a child of type [link node_pcdata] with value `"This is a node"`. pugixml provides a special class, `xml_text`, to work with such data. Working with text objects to modify data is described in [link manual.modify.text the documentation for modifying document data]; this section describes the access interface of `xml_text`.
+
+[#xml_node::text]
+You can get the text object from a node by using `text()` method:
+    
+[source]
+----
+xml_text xml_node::text() const;
+----
+
+If the node has a type `node_pcdata` or `node_cdata`, then the node itself is used to return data; otherwise, a first child node of type `node_pcdata` or `node_cdata` is used.
+
+[#xml_text::empty]
+[#xml_text::unspecified_bool_type]
+You can check if the text object is bound to a valid PCDATA/CDATA node by using it as a boolean value, i.e. `if (text) { ... }` or `if (!text) { ... }`. Alternatively you can check it by using the `empty()` method:
+
+[source]
+----
+bool xml_text::empty() const;
+----
+
+[#xml_text::get]
+Given a text object, you can get the contents (i.e. the value of PCDATA/CDATA node) by using the following function:
+
+[source]
+----
+const char_t* xml_text::get() const;
+----
+
+In case text object is empty, the function returns an empty string - it never returns a null pointer.
+
+[#xml_text::as_string][#xml_text::as_int][#xml_text::as_uint][#xml_text::as_double][#xml_text::as_float][#xml_text::as_bool][#xml_text::as_llong][#xml_text::as_ullong]
+If you need a non-empty string if the text object is empty, or if the text contents is actually a number or a boolean that is stored as a string, you can use the following accessors:
+
+[source]
+----
+const char_t* xml_text::as_string(const char_t* def = "") const;
+int xml_text::as_int(int def = 0) const;
+unsigned int xml_text::as_uint(unsigned int def = 0) const;
+double xml_text::as_double(double def = 0) const;
+float xml_text::as_float(float def = 0) const;
+bool xml_text::as_bool(bool def = false) const;
+long long xml_text::as_llong(long long def = 0) const;
+unsigned long long xml_text::as_ullong(unsigned long long def = 0) const;
+----
+
+All of the above functions have the same semantics as similar `xml_attribute` members: they return the default argument if the text object is empty, they convert the text contents to a target type using the same rules and restrictions. You can [link xml_attribute::as_int refer to documentation for the attribute functions] for details.
+
+[#xml_text::data]
+`xml_text` is essentially a helper class that operates on `xml_node` values. It is bound to a node of type [link node_pcdata] or [link node_cdata]. You can use the following function to retrieve this node:
+
+[source]
+----
+xml_node xml_text::data() const;
+----
+
+Essentially, assuming `text` is an `xml_text` object, calling `text.get()` is equivalent to calling `text.data().value()`.
+
+This is an example of using `xml_text` object (link:samples/text.cpp[]):
+
+[source,indent=0]

+include::samples/text.cpp[tags=access]

+
+[[access.misc]]
+=== Miscellaneous functions
+
+[#xml_node::root]
+If you need to get the document root of some node, you can use the following function:
+
+[source]
+----
+xml_node xml_node::root() const;
+----
+
+This function returns the node with type [link node_document], which is the root node of the document the node belongs to (unless the node is null, in which case null node is returned).
+
+[#xml_node::path]
+[#xml_node::first_element_by_path]
+While pugixml supports complex XPath expressions, sometimes a simple path handling facility is needed. There are two functions, for getting node path and for converting path to a node:
+
+[source]
+----
+string_t xml_node::path(char_t delimiter = '/') const;
+xml_node xml_node::first_element_by_path(const char_t* path, char_t delimiter = '/') const;
+----
+
+Node paths consist of node names, separated with a delimiter (which is `/` by default); also paths can contain self (`.`) and parent (`..`) pseudo-names, so that this is a valid path: `"../../foo/./bar"`. `path` returns the path to the node from the document root, `first_element_by_path` looks for a node represented by a given path; a path can be an absolute one (absolute paths start with the delimiter), in which case the rest of the path is treated as document root relative, and relative to the given node. For example, in the following document: `<a><b><c/></b></a>`, node `<c/>` has path `"a/b/c"`; calling `first_element_by_path` for document with path `"a/b"` results in node `<b/>`; calling `first_element_by_path` for node `<a/>` with path `"../a/./b/../."` results in node `<a/>`; calling `first_element_by_path` with path `"/a"` results in node `<a/>` for any node.
+
+In case path component is ambiguous (if there are two nodes with given name), the first one is selected; paths are not guaranteed to uniquely identify nodes in a document. If any component of a path is not found, the result of `first_element_by_path` is null node; also `first_element_by_path` returns null node for null nodes, in which case the path does not matter. `path` returns an empty string for null nodes. 
+
+NOTE: `path` function returns the result as STL string, and thus is not available if [link PUGIXML_NO_STL] is defined.
+
+[#xml_node::offset_debug]
+pugixml does not record row/column information for nodes upon parsing for efficiency reasons. However, if the node has not changed in a significant way since parsing (the name/value are not changed, and the node itself is the original one, i.e. it was not deleted from the tree and re-added later), it is possible to get the offset from the beginning of XML buffer:
+
+[source]
+----
+ptrdiff_t xml_node::offset_debug() const;
+----
+
+If the offset is not available (this happens if the node is null, was not originally parsed from a stream, or has changed in a significant way), the function returns -1. Otherwise it returns the offset to node's data from the beginning of XML buffer in [link char_t pugi::char_t] units. For more information on parsing offsets, see [link xml_parse_result::offset parsing error handling documentation].
+
+[[modify]]
+== Modifying document data
+
+The document in pugixml is fully mutable: you can completely change the document structure and modify the data of nodes/attributes. This section provides documentation for the relevant functions. All functions take care of memory management and structural integrity themselves, so they always result in structurally valid tree - however, it is possible to create an invalid XML tree (for example, by adding two attributes with the same name or by setting attribute/node name to empty/invalid string). Tree modification is optimized for performance and for memory consumption, so if you have enough memory you can create documents from scratch with pugixml and later save them to file/stream instead of relying on error-prone manual text writing and without too much overhead.
+
+All member functions that change node/attribute data or structure are non-constant and thus can not be called on constant handles. However, you can easily convert constant handle to non-constant one by simple assignment: `void foo(const pugi::xml_node& n) { pugi::xml_node nc = n; }`, so const-correctness here mainly provides additional documentation.
+

+
+[[modify.nodedata]]
+=== Setting node data
+
+[#xml_node::set_name][#xml_node::set_value]
+As discussed before, nodes can have name and value, both of which are strings. Depending on node type, name or value may be absent. [link node_document] nodes do not have a name or value, [link node_element] and [link node_declaration] nodes always have a name but never have a value, [link node_pcdata], [link node_cdata], [link node_comment] and [link node_doctype] nodes never have a name but always have a value (it may be empty though), [link node_pi] nodes always have a name and a value (again, value may be empty). In order to set node's name or value, you can use the following functions:
+
+[source]
+----
+bool xml_node::set_name(const char_t* rhs);
+bool xml_node::set_value(const char_t* rhs);
+----
+
+Both functions try to set the name/value to the specified string, and return the operation result. The operation fails if the node can not have name or value (for instance, when trying to call `set_name` on a [link node_pcdata] node), if the node handle is null, or if there is insufficient memory to handle the request. The provided string is copied into document managed memory and can be destroyed after the function returns (for example, you can safely pass stack-allocated buffers to these functions). The name/value content is not verified, so take care to use only valid XML names, or the document may become malformed.
+
+There is no equivalent of [link xml_node::child_value child_value] function for modifying text children of the node.
+
+This is an example of setting node name and value (link:samples/modify_base.cpp[]):
+
+[source,indent=0]
+----
+include::samples/modify_base.cpp[tags=node] 
+----
+
+[[modify.attrdata]]
+=== Setting attribute data
+
+[#xml_attribute::set_name][#xml_attribute::set_value]
+All attributes have name and value, both of which are strings (value may be empty). You can set them with the following functions:
+
+[source]
+----
+bool xml_attribute::set_name(const char_t* rhs);
+bool xml_attribute::set_value(const char_t* rhs);
+----
+
+Both functions try to set the name/value to the specified string, and return the operation result. The operation fails if the attribute handle is null, or if there is insufficient memory to handle the request. The provided string is copied into document managed memory and can be destroyed after the function returns (for example, you can safely pass stack-allocated buffers to these functions). The name/value content is not verified, so take care to use only valid XML names, or the document may become malformed.
+
+In addition to string functions, several functions are provided for handling attributes with numbers and booleans as values:
+
+[source]
+----
+bool xml_attribute::set_value(int rhs);
+bool xml_attribute::set_value(unsigned int rhs);
+bool xml_attribute::set_value(double rhs);
+bool xml_attribute::set_value(float rhs);
+bool xml_attribute::set_value(bool rhs);
+bool xml_attribute::set_value(long long rhs);
+bool xml_attribute::set_value(unsigned long long rhs);
+----
+    
+The above functions convert the argument to string and then call the base `set_value` function. Integers are converted to a decimal form, floating-point numbers are converted to either decimal or scientific form, depending on the number magnitude, boolean values are converted to either `"true"` or `"false"`.
+
+CAUTION: Number conversion functions depend on current C locale as set with `setlocale`, so may generate unexpected results if the locale is different from `"C"`.
+
+NOTE: `set_value` overloads with `long long` type are only available if your platform has reliable support for the type, including string conversions.
+
+[#xml_attribute::assign]
+
+For convenience, all `set_value` functions have the corresponding assignment operators:
+
+[source]
+----
+xml_attribute& xml_attribute::operator=(const char_t* rhs);
+xml_attribute& xml_attribute::operator=(int rhs);
+xml_attribute& xml_attribute::operator=(unsigned int rhs);
+xml_attribute& xml_attribute::operator=(double rhs);
+xml_attribute& xml_attribute::operator=(float rhs);
+xml_attribute& xml_attribute::operator=(bool rhs);
+xml_attribute& xml_attribute::operator=(long long rhs);
+xml_attribute& xml_attribute::operator=(unsigned long long rhs);
+----
+
+These operators simply call the right `set_value` function and return the attribute they're called on; the return value of `set_value` is ignored, so errors are ignored.
+
+This is an example of setting attribute name and value (link:samples/modify_base.cpp[]):

+=== Adding nodes/attributes

+Nodes and attributes do not exist without a document tree, so you can't create them without adding them to some document. A node or attribute can be created at the end of node/attribute list or before/after some other node:
+
+[source]
+----
+xml_attribute xml_node::append_attribute(const char_t* name);
+xml_attribute xml_node::prepend_attribute(const char_t* name);
+xml_attribute xml_node::insert_attribute_after(const char_t* name, const xml_attribute& attr);
+xml_attribute xml_node::insert_attribute_before(const char_t* name, const xml_attribute& attr);
+
+xml_node xml_node::append_child(xml_node_type type = node_element);
+xml_node xml_node::prepend_child(xml_node_type type = node_element);
+xml_node xml_node::insert_child_after(xml_node_type type, const xml_node& node);
+xml_node xml_node::insert_child_before(xml_node_type type, const xml_node& node);
+
+xml_node xml_node::append_child(const char_t* name);
+xml_node xml_node::prepend_child(const char_t* name);
+xml_node xml_node::insert_child_after(const char_t* name, const xml_node& node);
+xml_node xml_node::insert_child_before(const char_t* name, const xml_node& node);
+----
+
+`append_attribute` and `append_child` create a new node/attribute at the end of the corresponding list of the node the method is called on; `prepend_attribute` and `prepend_child` create a new node/attribute at the beginning of the list; `insert_attribute_after`, `insert_attribute_before`, `insert_child_after` and `insert_attribute_before` add the node/attribute before or after the specified node/attribute.
+
+Attribute functions create an attribute with the specified name; you can specify the empty name and change the name later if you want to. Node functions with the `type` argument create the node with the specified type; since node type can't be changed, you have to know the desired type beforehand. Also note that not all types can be added as children; see below for clarification. Node functions with the `name` argument create the element node ([link node_element]) with the specified name.
+
+All functions return the handle to the created object on success, and null handle on failure. There are several reasons for failure:
+
+* Adding fails if the target node is null;
+* Only [link node_element] nodes can contain attributes, so attribute adding fails if node is not an element;
+* Only [link node_document] and [link node_element] nodes can contain children, so child node adding fails if the target node is not an element or a document;
+* [link node_document] and [link node_null] nodes can not be inserted as children, so passing [link node_document] or [link node_null] value as `type` results in operation failure;
+* [link node_declaration] nodes can only be added as children of the document node; attempt to insert declaration node as a child of an element node fails;
+* Adding node/attribute results in memory allocation, which may fail;
+* Insertion functions fail if the specified node or attribute is null or is not in the target node's children/attribute list.
+
+Even if the operation fails, the document remains in consistent state, but the requested node/attribute is not added.
+
+CAUTION: `attribute()` and `child()` functions do not add attributes or nodes to the tree, so code like `node.attribute("id") = 123;` will not do anything if `node` does not have an attribute with name `"id"`. Make sure you're operating with existing attributes/nodes by adding them if necessary.
+
+This is an example of adding new attributes/nodes to the document (link:samples/modify_add.cpp[]):

+
+[[modify.remove]]
+=== Removing nodes/attributes
+
+[#xml_node::remove_attribute][#xml_node::remove_child]
+If you do not want your document to contain some node or attribute, you can remove it with one of the following functions:
+
+[source]
+----
+bool xml_node::remove_attribute(const xml_attribute& a);
+bool xml_node::remove_child(const xml_node& n);
+----
+
+`remove_attribute` removes the attribute from the attribute list of the node, and returns the operation result. `remove_child` removes the child node with the entire subtree (including all descendant nodes and attributes) from the document, and returns the operation result. Removing fails if one of the following is true:
+
+* The node the function is called on is null;
+* The attribute/node to be removed is null;
+* The attribute/node to be removed is not in the node's attribute/child list.
+
+Removing the attribute or node invalidates all handles to the same underlying object, and also invalidates all iterators pointing to the same object. Removing node also invalidates all past-the-end iterators to its attribute or child node list. Be careful to ensure that all such handles and iterators either do not exist or are not used after the attribute/node is removed.
+
+If you want to remove the attribute or child node by its name, two additional helper functions are available:
+
+[source]
+----
+bool xml_node::remove_attribute(const char_t* name);
+bool xml_node::remove_child(const char_t* name);
+----
+
+These functions look for the first attribute or child with the specified name, and then remove it, returning the result. If there is no attribute or child with such name, the function returns `false`; if there are two nodes with the given name, only the first node is deleted. If you want to delete all nodes with the specified name, you can use code like this: `while (node.remove_child("tool")) ;`.
+
+This is an example of removing attributes/nodes from the document (link:samples/modify_remove.cpp[]):

+
+[[modify.text]]
+=== Working with text contents
+
+pugixml provides a special class, `xml_text`, to work with text contents stored as a value of some node, i.e. `<node><description>This is a node</description></node>`. Working with text objects to retrieve data is described in [link manual.access.text the documentation for accessing document data]; this section describes the modification interface of `xml_text`.
+
+[#xml_text::set]
+Once you have an `xml_text` object, you can set the text contents using the following function:
+
+[source]
+----
+bool xml_text::set(const char_t* rhs);
+----
+
+This function tries to set the contents to the specified string, and returns the operation result. The operation fails if the text object was retrieved from a node that can not have a value and is not an element node (i.e. it is a [link node_declaration] node), if the text object is empty, or if there is insufficient memory to handle the request. The provided string is copied into document managed memory and can be destroyed after the function returns (for example, you can safely pass stack-allocated buffers to this function). Note that if the text object was retrieved from an element node, this function creates the PCDATA child node if necessary (i.e. if the element node does not have a PCDATA/CDATA child already).
+
+[#xml_text::set_value]
+In addition to a string function, several functions are provided for handling text with numbers and booleans as contents:
+
+[source]
+----
+bool xml_text::set(int rhs);
+bool xml_text::set(unsigned int rhs);
+bool xml_text::set(double rhs);
+bool xml_text::set(float rhs);
+bool xml_text::set(bool rhs);
+bool xml_text::set(long long rhs);
+bool xml_text::set(unsigned long long rhs);
+----
+    
+The above functions convert the argument to string and then call the base `set` function. These functions have the same semantics as similar `xml_attribute` functions. You can [link xml_attribute::set_value refer to documentation for the attribute functions] for details.
+
+[#xml_text::assign]
+
+For convenience, all `set` functions have the corresponding assignment operators:
+
+[source]
+----
+xml_text& xml_text::operator=(const char_t* rhs);
+xml_text& xml_text::operator=(int rhs);
+xml_text& xml_text::operator=(unsigned int rhs);
+xml_text& xml_text::operator=(double rhs);
+xml_text& xml_text::operator=(float rhs);
+xml_text& xml_text::operator=(bool rhs);
+xml_text& xml_text::operator=(long long rhs);
+xml_text& xml_text::operator=(unsigned long long rhs);
+----
+
+These operators simply call the right `set` function and return the attribute they're called on; the return value of `set` is ignored, so errors are ignored.
+
+This is an example of using `xml_text` object to modify text contents (link:samples/text.cpp[]):

+
+[[modify.clone]]
+=== Cloning nodes/attributes
+
+[#xml_node::prepend_copy][#xml_node::append_copy][#xml_node::insert_copy_after][#xml_node::insert_copy_before]
+With the help of previously described functions, it is possible to create trees with any contents and structure, including cloning the existing data. However since this is an often needed operation, pugixml provides built-in node/attribute cloning facilities. Since nodes and attributes do not exist without a document tree, you can't create a standalone copy - you have to immediately insert it somewhere in the tree. For this, you can use one of the following functions:
+
+[source]
+----
+xml_attribute xml_node::append_copy(const xml_attribute& proto);
+xml_attribute xml_node::prepend_copy(const xml_attribute& proto);
+xml_attribute xml_node::insert_copy_after(const xml_attribute& proto, const xml_attribute& attr);
+xml_attribute xml_node::insert_copy_before(const xml_attribute& proto, const xml_attribute& attr);
+
+xml_node xml_node::append_copy(const xml_node& proto);
+xml_node xml_node::prepend_copy(const xml_node& proto);
+xml_node xml_node::insert_copy_after(const xml_node& proto, const xml_node& node);
+xml_node xml_node::insert_copy_before(const xml_node& proto, const xml_node& node);
+----
+
+These functions mirror the structure of `append_child`, `prepend_child`, `insert_child_before` and related functions - they take the handle to the prototype object, which is to be cloned, insert a new attribute/node at the appropriate place, and then copy the attribute data or the whole node subtree to the new object. The functions return the handle to the resulting duplicate object, or null handle on failure.
+
+The attribute is copied along with the name and value; the node is copied along with its type, name and value; additionally attribute list and all children are recursively cloned, resulting in the deep subtree clone. The prototype object can be a part of the same document, or a part of any other document.
+
+The failure conditions resemble those of `append_child`, `insert_child_before` and related functions, [link xml_node::append_child consult their documentation for more information]. There are additional caveats specific to cloning functions:
+
+* Cloning null handles results in operation failure;
+* Node cloning starts with insertion of the node of the same type as that of the prototype; for this reason, cloning functions can not be directly used to clone entire documents, since [link node_document] is not a valid insertion type. The example below provides a workaround.
+* It is possible to copy a subtree as a child of some node inside this subtree, i.e. `node.append_copy(node.parent().parent());`. This is a valid operation, and it results in a clone of the subtree in the state before cloning started, i.e. no infinite recursion takes place.
+
+This is an example with one possible implementation of include tags in XML (link:samples/include.cpp[]). It illustrates node cloning and usage of other document modification functions:
+
+[source,indent=0]
+----
+include::samples/include.cpp[tags=code] 
+----
+
+[[modify.move]]
+=== Moving nodes
+
+[#xml_node::prepend_move][#xml_node::append_move][#xml_node::insert_move_after][#xml_node::insert_move_before]
+Sometimes instead of cloning a node you need to move an existing node to a different position in a tree. This can be accomplished by copying the node and removing the original; however, this is expensive since it results in a lot of extra operations. For moving nodes within the same document tree, you can use of the following functions instead:
+
+[source]
+----
+xml_node xml_node::append_move(const xml_node& moved);
+xml_node xml_node::prepend_move(const xml_node& moved);
+xml_node xml_node::insert_move_after(const xml_node& moved, const xml_node& node);
+xml_node xml_node::insert_move_before(const xml_node& moved, const xml_node& node);
+----
+
+These functions mirror the structure of `append_copy`, `prepend_copy`, `insert_copy_before` and `insert_copy_after` - they take the handle to the moved object and move it to the appropriate place with all attributes and/or child nodes. The functions return the handle to the resulting object (which is the same as the moved object), or null handle on failure.
+
+The failure conditions resemble those of `append_child`, `insert_child_before` and related functions, [link xml_node::append_child consult their documentation for more information]. There are additional caveats specific to moving functions:
+
+* Moving null handles results in operation failure;
+* Moving is only possible for nodes that belong to the same document; attempting to move nodes between documents will fail.
+* `insert_move_after` and `insert_move_before` functions fail if the moved node is the same as the `node` argument (this operation would be a no-op otherwise).
+* It is impossible to move a subtree to a child of some node inside this subtree, i.e. `node.append_move(node.parent().parent());` will fail.
+
+[[modify.fragments]]
+=== Assembling document from fragments
+
+[#xml_node::append_buffer]
+pugixml provides several ways to assemble an XML document from other XML documents. Assuming there is a set of document fragments, represented as in-memory buffers, the implementation choices are as follows:
+
+* Use a temporary document to parse the data from a string, then clone the nodes to a destination node. For example:
+
+[source]
+----
+bool append_fragment(pugi::xml_node target, const char* buffer, size_t size)
+{
+    pugi::xml_document doc;
+    if (!doc.load_buffer(buffer, size)) return false;
+
+    for (pugi::xml_node child = doc.first_child(); child; child = child.next_sibling())
+        target.append_copy(child);
+}
+----
+
+* Cache the parsing step - instead of keeping in-memory buffers, keep document objects that already contain the parsed fragment:
+
+[source]
+----
+bool append_fragment(pugi::xml_node target, const pugi::xml_document& cached_fragment)
+{
+    for (pugi::xml_node child = cached_fragment.first_child(); child; child = child.next_sibling())
+        target.append_copy(child);
+}
+----
+
+* Use `xml_node::append_buffer` directly:
+
+[source]
+----
+xml_parse_result xml_node::append_buffer(const void* contents, size_t size, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
+----
+
+The first method is more convenient, but slower than the other two. The relative performance of `append_copy` and `append_buffer` depends on the buffer format - usually `append_buffer` is faster if the buffer is in native encoding (UTF-8 or wchar_t, depending on `PUGIXML_WCHAR_MODE`). At the same time it might be less efficient in terms of memory usage - the implementation makes a copy of the provided buffer, and the copy has the same lifetime as the document - the memory used by that copy will be reclaimed after the document is destroyed, but no sooner. Even deleting all nodes in the document, including the appended ones, won't reclaim the memory.
+
+`append_buffer` behaves in the same way as [link xml_document::load_buffer] - the input buffer is a byte buffer, with size in bytes; the buffer is not modified and can be freed after the function returns.
+
+[#status_append_invalid_root]
+Since `append_buffer` needs to append child nodes to the current node, it only works if the current node is either document or element node. Calling `append_buffer` on a node with any other type results in an error with `status_append_invalid_root` status.
+
+[[saving]]
+== Saving document
+
+Often after creating a new document or loading the existing one and processing it, it is necessary to save the result back to file. Also it is occasionally useful to output the whole document or a subtree to some stream; use cases include debug printing, serialization via network or other text-oriented medium, etc. pugixml provides several functions to output any subtree of the document to a file, stream or another generic transport interface; these functions allow to customize the output format (see <<saving.options>>), and also perform necessary encoding conversions (see <<saving.encoding>>). This section documents the relevant functionality.
+
+Before writing to the destination the node/attribute data is properly formatted according to the node type; all special XML symbols, such as < and &, are properly escaped (unless [link format_no_escapes] flag is set). In order to guard against forgotten node/attribute names, empty node/attribute names are printed as `":anonymous"`. For well-formed output, make sure all node and attribute names are set to meaningful values.
+
+CDATA sections with values that contain `"]]>"` are split into several sections as follows: section with value `"pre]]>post"` is written as `<![CDATA[pre]]]]><![CDATA[>post]]>`. While this alters the structure of the document (if you load the document after saving it, there will be two CDATA sections instead of one), this is the only way to escape CDATA contents.
+
+[[saving.file]]
+=== Saving document to a file
+
+[#xml_document::save_file]
+[#xml_document::save_file_wide]
+If you want to save the whole document to a file, you can use one of the following functions:
+
+[source]
+----
+bool xml_document::save_file(const char* path, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto) const;
+bool xml_document::save_file(const wchar_t* path, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto) const;
+----
+
+These functions accept file path as its first argument, and also three optional arguments, which specify indentation and other output options (see <<saving.options>>) and output data encoding (see <<saving.encoding>>). The path has the target operating system format, so it can be a relative or absolute one, it should have the delimiters of the target system, it should have the exact case if the target file system is case-sensitive, etc.
+
+File path is passed to the system file opening function as is in case of the first function (which accepts `const char* path`); the second function either uses a special file opening function if it is provided by the runtime library or converts the path to UTF-8 and uses the system file opening function.
+
+[#xml_writer_file]
+`save_file` opens the target file for writing, outputs the requested header (by default a document declaration is output, unless the document already has one), and then saves the document contents. If the file could not be opened, the function returns `false`. Calling `save_file` is equivalent to creating an `xml_writer_file` object with `FILE*` handle as the only constructor argument and then calling `save`; see <<saving.writer>> for writer interface details.
+
+This is a simple example of saving XML document to file (link:samples/save_file.cpp[]):
+
+[source,indent=0]
+----
+include::samples/save_file.cpp[tags=code] 
+----
+
+[[saving.stream]]
+=== Saving document to C{plus}{plus} IOstreams
+
+[#xml_document::save_stream]
+To enhance interoperability pugixml provides functions for saving document to any object which implements C{plus}{plus} `std::ostream` interface. This allows you to save documents to any standard C{plus}{plus} stream (i.e. file stream) or any third-party compliant implementation (i.e. Boost Iostreams). Most notably, this allows for easy debug output, since you can use `std::cout` stream as saving target. There are two functions, one works with narrow character streams, another handles wide character ones:
+
+[source]
+----
+void xml_document::save(std::ostream& stream, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto) const;
+void xml_document::save(std::wostream& stream, const char_t* indent = "\t", unsigned int flags = format_default) const;
+----
+
+`save` with `std::ostream` argument saves the document to the stream in the same way as `save_file` (i.e. with requested header and with encoding conversions). On the other hand, `save` with `std::wstream` argument saves the document to the wide stream with [link encoding_wchar] encoding.  Because of this, using `save` with wide character streams requires careful (usually platform-specific) stream setup (i.e. using the `imbue` function). Generally use of wide streams is discouraged, however it provides you with the ability to save documents to non-Unicode encodings, i.e. you can save Shift-JIS encoded data if you set the correct locale.
+
+[#xml_writer_stream]
+Calling `save` with stream target is equivalent to creating an `xml_writer_stream` object with stream as the only constructor argument and then calling `save`; see <<saving.writer>> for writer interface details.
+
+This is a simple example of saving XML document to standard output (link:samples/save_stream.cpp[]):
+
+[source,indent=0]
+----
+include::samples/save_stream.cpp[tags=code] 
+----
+
+[[saving.writer]]
+=== Saving document via writer interface
+
+[#xml_document::save][#xml_writer][#xml_writer::write]
+All of the above saving functions are implemented in terms of writer interface. This is a simple interface with a single function, which is called several times during output process with chunks of document data as input:
+
+[source]
+----
+class xml_writer
+{
+public:
+    virtual void write(const void* data, size_t size) = 0;
+};
+
+void xml_document::save(xml_writer& writer, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto) const;
+----
+
+In order to output the document via some custom transport, for example sockets, you should create an object which implements `xml_writer` interface and pass it to `save` function. `xml_writer::write` function is called with a buffer as an input, where `data` points to buffer start, and `size` is equal to the buffer size in bytes. `write` implementation must write the buffer to the transport; it can not save the passed buffer pointer, as the buffer contents will change after `write` returns. The buffer contains the chunk of document data in the desired encoding.
+
+`write` function is called with relatively large blocks (size is usually several kilobytes, except for the last block that may be small), so there is often no need for additional buffering in the implementation.
+
+This is a simple example of custom writer for saving document data to STL string (link:samples/save_custom_writer.cpp[]); read the sample code for more complex examples:
+
+[source,indent=0]
+----
+include::samples/save_custom_writer.cpp[tags=code] 
+----
+
+[[saving.subtree]]
+=== Saving a single subtree
+
+[#xml_node::print][#xml_node::print_stream]
+While the previously described functions save the whole document to the destination, it is easy to save a single subtree. The following functions are provided:
+
+[source]
+----
+void xml_node::print(std::ostream& os, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto, unsigned int depth = 0) const;
+void xml_node::print(std::wostream& os, const char_t* indent = "\t", unsigned int flags = format_default, unsigned int depth = 0) const;
+void xml_node::print(xml_writer& writer, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto, unsigned int depth = 0) const;
+----
+
+These functions have the same arguments with the same meaning as the corresponding `xml_document::save` functions, and allow you to save the subtree to either a C{plus}{plus} IOstream or to any object that implements `xml_writer` interface.
+
+Saving a subtree differs from saving the whole document: the process behaves as if [link format_write_bom] is off, and [link format_no_declaration] is on, even if actual values of the flags are different. This means that BOM is not written to the destination, and document declaration is only written if it is the node itself or is one of node's children. Note that this also holds if you're saving a document; this example (link:samples/save_subtree.cpp[]) illustrates the difference:
+
+[source,indent=0]
+----
+include::samples/save_subtree.cpp[tags=code] 
+----
+
+[[saving.options]]
+=== Output options
+
+All saving functions accept the optional parameter `flags`. This is a bitmask that customizes the output format; you can select the way the document nodes are printed and select the needed additional information that is output before the document contents.
+
+NOTE: You should use the usual bitwise arithmetics to manipulate the bitmask: to enable a flag, use `mask | flag`; to disable a flag, use `mask & ~flag`.
+
+These flags control the resulting tree contents:
+
+* [anchor format_indent] determines if all nodes should be indented with the indentation string (this is an additional parameter for all saving functions, and is `"\t"` by default). If this flag is on, before every node the indentation string is output several times, where the amount of indentation depends on the node's depth relative to the output subtree. This flag has no effect if [link format_raw] is enabled. This flag is *on* by default.
+[lbr]
+
+* [anchor format_raw] switches between formatted and raw output. If this flag is on, the nodes are not indented in any way, and also no newlines that are not part of document text are printed. Raw mode can be used for serialization where the result is not intended to be read by humans; also it can be useful if the document was parsed with [link parse_ws_pcdata] flag, to preserve the original document formatting as much as possible. This flag is *off* by default.
+[lbr]
+
+* [anchor format_no_escapes] disables output escaping for attribute values and PCDATA contents. If this flag is off, special symbols (', &, <, >) and all non-printable characters (those with codepoint values less than 32) are converted to XML escape sequences (i.e. &amp;) during output. If this flag is on, no text processing is performed; therefore, output XML can be malformed if output contents contains invalid symbols (i.e. having a stray < in the PCDATA will make the output malformed). This flag is *off* by default.
+
+These flags control the additional output information:
+
+* [anchor format_no_declaration] disables default node declaration output. By default, if the document is saved via `save` or `save_file` function, and it does not have any document declaration, a default declaration is output before the document contents. Enabling this flag disables this declaration. This flag has no effect in `xml_node::print` functions: they never output the default declaration. This flag is *off* by default.
+[lbr]
+
+* [anchor format_write_bom] enables Byte Order Mark (BOM) output. By default, no BOM is output, so in case of non UTF-8 encodings the resulting document's encoding may not be recognized by some parsers and text editors, if they do not implement sophisticated encoding detection. Enabling this flag adds an encoding-specific BOM to the output. This flag has no effect in `xml_node::print` functions: they never output the BOM. This flag is *off* by default.
+
+* [anchor format_save_file_text] changes the file mode when using `save_file` function. By default, file is opened in binary mode, which means that the output file will
+contain platform-independent newline \n (ASCII 10). If this flag is on, file is opened in text mode, which on some systems changes the newline format (i.e. on Windows you can use this flag to output XML documents with \r\n (ASCII 13 10) newlines. This flag is *off* by default.
+
+Additionally, there is one predefined option mask:
+
+* [anchor format_default] is the default set of flags, i.e. it has all options set to their default values. It sets formatted output with indentation, without BOM and with default node declaration, if necessary.
+
+This is an example that shows the outputs of different output options (link:samples/save_options.cpp[]):
+
+[source,indent=0]
+----
+include::samples/save_options.cpp[tags=code] 
+----
+
+[[saving.encoding]]
+=== Encodings
+
+pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it's a strict subset of UTF-16) and handles all encoding conversions during output. The output encoding is set via the `encoding` parameter of saving functions, which is of type `xml_encoding`. The possible values for the encoding are documented in <<loading.encoding>>; the only flag that has a different meaning is `encoding_auto`.
+
+While all other flags set the exact encoding, `encoding_auto` is meant for automatic encoding detection. The automatic detection does not make sense for output encoding, since there is usually nothing to infer the actual encoding from, so here `encoding_auto` means UTF-8 encoding, which is the most popular encoding for XML data storage. This is also the default value of output encoding; specify another value if you do not want UTF-8 encoded output.
+
+Also note that wide stream saving functions do not have `encoding` argument and always assume [link encoding_wchar] encoding.
+
+NOTE: The current behavior for Unicode conversion is to skip all invalid UTF sequences during conversion. This behavior should not be relied upon; if your node/attribute names do not contain any valid UTF sequences, they may be output as if they are empty, which will result in malformed XML document.
+
+[[saving.declaration]]
+=== Customizing document declaration
+
+When you are saving the document using `xml_document::save()` or `xml_document::save_file()`, a default XML document declaration is output, if `format_no_declaration` is not specified and if the document does not have a declaration node. However, the default declaration is not customizable. If you want to customize the declaration output, you need to create the declaration node yourself.
+
+NOTE: By default the declaration node is not added to the document during parsing. If you just need to preserve the original declaration node, you have to add the flag [link parse_declaration] to the parsing flags; the resulting document will contain the original declaration node, which will be output during saving.
+
+Declaration node is a node with type [link node_declaration]; it behaves like an element node in that it has attributes with values (but it does not have child nodes). Therefore setting custom version, encoding or standalone declaration involves adding attributes and setting attribute values.
+
+This is an example that shows how to create a custom declaration node (link:samples/save_declaration.cpp[]):

+
+[[xpath]]
+== XPath
+
+If the task at hand is to select a subset of document nodes that match some criteria, it is possible to code a function using the existing traversal functionality for any practical criteria. However, often either a data-driven approach is desirable, in case the criteria are not predefined and come from a file, or it is inconvenient to use traversal interfaces and a higher-level DSL is required. There is a standard language for XML processing, XPath, that can be useful for these cases. pugixml implements an almost complete subset of XPath 1.0. Because of differences in document object model and some performance implications, there are minor violations of the official specifications, which can be found in <<xpath.w3c>>. The rest of this section describes the interface for XPath functionality. Please note that if you wish to learn to use XPath language, you have to look for other tutorials or manuals; for example, you can read http://www.w3schools.com/xpath/[W3Schools XPath tutorial], http://www.tizag.com/xmlTutorial/xpathtutorial.php[XPath tutorial at tizag.com], and http://www.w3.org/TR/xpath/[the XPath 1.0 specification].
+
+[[xpath.types]]
+=== XPath types
+
+[#xpath_value_type][#xpath_type_number][#xpath_type_string][#xpath_type_boolean][#xpath_type_node_set][#xpath_type_none]
+Each XPath expression can have one of the following types: boolean, number, string or node set. Boolean type corresponds to `bool` type, number type corresponds to `double` type, string type corresponds to either `std::string` or `std::wstring`, depending on whether [link manual.dom.unicode wide character interface is enabled], and node set corresponds to [link xpath_node_set] type. There is an enumeration, `xpath_value_type`, which can take the values `xpath_type_boolean`, `xpath_type_number`, `xpath_type_string` or `xpath_type_node_set`, accordingly.
+
+[#xpath_node][#xpath_node::node][#xpath_node::attribute][#xpath_node::parent]
+Because an XPath node can be either a node or an attribute, there is a special type, `xpath_node`, which is a discriminated union of these types. A value of this type contains two node handles, one of `xml_node` type, and another one of `xml_attribute` type; at most one of them can be non-null. The accessors to get these handles are available:
+
+[source]
+----
+xml_node xpath_node::node() const;
+xml_attribute xpath_node::attribute() const;
+----
+
+XPath nodes can be null, in which case both accessors return null handles.
+
+Note that as per XPath specification, each XPath node has a parent, which can be retrieved via this function:
+
+[source]
+----
+xml_node xpath_node::parent() const;
+----
+
+`parent` function returns the node's parent if the XPath node corresponds to `xml_node` handle (equivalent to `node().parent()`), or the node to which the attribute belongs to, if the XPath node corresponds to `xml_attribute` handle. For null nodes, `parent` returns null handle.
+
+[#xpath_node::unspecified_bool_type][#xpath_node::comparison]
+Like node and attribute handles, XPath node handles can be implicitly cast to boolean-like object to check if it is a null node, and also can be compared for equality with each other.
+
+[#xpath_node::ctor]
+You can also create XPath nodes with one of the three constructors: the default constructor, the constructor that takes node argument, and the constructor that takes attribute and node arguments (in which case the attribute must belong to the attribute list of the node). The constructor from `xml_node` is implicit, so you can usually pass `xml_node` to functions that expect `xpath_node`. Apart from that you usually don't need to create your own XPath node objects, since they are returned to you via selection functions.
+
+[#xpath_node_set]
+XPath expressions operate not on single nodes, but instead on node sets. A node set is a collection of nodes, which can be optionally ordered in either a forward document order or a reverse one. Document order is defined in XPath specification; an XPath node is before another node in document order if it appears before it in XML representation of the corresponding document.
+
+[#xpath_node_set::const_iterator][#xpath_node_set::begin][#xpath_node_set::end]
+Node sets are represented by `xpath_node_set` object, which has an interface that resembles one of sequential random-access containers. It has an iterator type along with usual begin/past-the-end iterator accessors:
+
+[source]
+----
+typedef const xpath_node* xpath_node_set::const_iterator;
+const_iterator xpath_node_set::begin() const;
+const_iterator xpath_node_set::end() const;
+----
+
+[#xpath_node_set::index][#xpath_node_set::size][#xpath_node_set::empty]
+And it also can be iterated via indices, just like `std::vector`:
+
+[source]
+----
+const xpath_node& xpath_node_set::operator[](size_t index) const;
+size_t xpath_node_set::size() const;
+bool xpath_node_set::empty() const;
+----
+
+All of the above operations have the same semantics as that of `std::vector`: the iterators are random-access, all of the above operations are constant time, and accessing the element at index that is greater or equal than the set size results in undefined behavior. You can use both iterator-based and index-based access for iteration, however the iterator-based one can be faster.
+
+[#xpath_node_set::type][#xpath_node_set::type_unsorted][#xpath_node_set::type_sorted][#xpath_node_set::type_sorted_reverse][#xpath_node_set::sort]
+The order of iteration depends on the order of nodes inside the set; the order can be queried via the following function:
+
+[source]
+----
+enum xpath_node_set::type_t {type_unsorted, type_sorted, type_sorted_reverse};
+type_t xpath_node_set::type() const;
+----
+
+`type` function returns the current order of nodes; `type_sorted` means that the nodes are in forward document order, `type_sorted_reverse` means that the nodes are in reverse document order, and `type_unsorted` means that neither order is guaranteed (nodes can accidentally be in a sorted order even if `type()` returns `type_unsorted`). If you require a specific order of iteration, you can change it via `sort` function:
+
+[source]
+----
+void xpath_node_set::sort(bool reverse = false);
+----
+
+Calling `sort` sorts the nodes in either forward or reverse document order, depending on the argument; after this call `type()` will return `type_sorted` or `type_sorted_reverse`.
+
+[#xpath_node_set::first]
+Often the actual iteration is not needed; instead, only the first element in document order is required. For this, a special accessor is provided:
+
+[source]
+----
+xpath_node xpath_node_set::first() const;
+----
+
+This function returns the first node in forward document order from the set, or null node if the set is empty. Note that while the result of the node does not depend on the order of nodes in the set (i.e. on the result of `type()`), the complexity does - if the set is sorted, the complexity is constant, otherwise it is linear in the number of elements or worse.
+
+[#xpath_node_set::ctor]
+While in the majority of cases the node set is returned by XPath functions, sometimes there is a need to manually construct a node set. For such cases, a constructor is provided which takes an iterator range (`const_iterator` is a typedef for `const xpath_node*`), and an optional type:
+
+[source]
+----
+xpath_node_set::xpath_node_set(const_iterator begin, const_iterator end, type_t type = type_unsorted);
+----
+
+The constructor copies the specified range and sets the specified type. The objects in the range are not checked in any way; you'll have to ensure that the range contains no duplicates, and that the objects are sorted according to the `type` parameter. Otherwise XPath operations with this set may produce unexpected results.
+
+[[xpath.select]]
+=== Selecting nodes via XPath expression
+
+[#xml_node::select_node][#xml_node::select_nodes]
+If you want to select nodes that match some XPath expression, you can do it with the following functions:
+
+[source]
+----
+xpath_node xml_node::select_node(const char_t* query, xpath_variable_set* variables = 0) const;
+xpath_node_set xml_node::select_nodes(const char_t* query, xpath_variable_set* variables = 0) const;
+----
+
+`select_nodes` function compiles the expression and then executes it with the node as a context node, and returns the resulting node set. `select_node` returns only the first node in document order from the result, and is equivalent to calling `select_nodes(query).first()`. If the XPath expression does not match anything, or the node handle is null, `select_nodes` returns an empty set, and `select_node` returns null XPath node.
+
+If exception handling is not disabled, both functions throw [link xpath_exception] if the query can not be compiled or if it returns a value with type other than node set; see <<xpath.errors>> for details.
+
+[#xml_node::select_node_precomp][#xml_node::select_nodes_precomp]
+While compiling expressions is fast, the compilation time can introduce a significant overhead if the same expression is used many times on small subtrees. If you're doing many similar queries, consider compiling them into query objects (see <<xpath.query>> for further reference). Once you get a compiled query object, you can pass it to select functions instead of an expression string:
+
+[source]
+----
+xpath_node xml_node::select_node(const xpath_query& query) const;
+xpath_node_set xml_node::select_nodes(const xpath_query& query) const;
+----
+
+If exception handling is not disabled, both functions throw [link xpath_exception] if the query returns a value with type other than node set.
+
+This is an example of selecting nodes using XPath expressions (link:samples/xpath_select.cpp[]):
+
+[source,indent=0]
+----
+include::samples/xpath_select.cpp[tags=code] 
+----
+
+[[xpath.query]]
+=== Using query objects
+
+[#xpath_query]
+When you call `select_nodes` with an expression string as an argument, a query object is created behind the scenes. A query object represents a compiled XPath expression. Query objects can be needed in the following circumstances:
+
+* You can precompile expressions to query objects to save compilation time if it becomes an issue;
+* You can use query objects to evaluate XPath expressions which result in booleans, numbers or strings;
+* You can get the type of expression value via query object.
+
+Query objects correspond to `xpath_query` type. They are immutable and non-copyable: they are bound to the expression at creation time and can not be cloned. If you want to put query objects in a container, allocate them on heap via `new` operator and store pointers to `xpath_query` in the container.
+
+[#xpath_query::ctor]
+You can create a query object with the constructor that takes XPath expression as an argument:
+
+[source]
+----
+explicit xpath_query::xpath_query(const char_t* query, xpath_variable_set* variables = 0);
+----
+
+[#xpath_query::return_type]
+The expression is compiled and the compiled representation is stored in the new query object. If compilation fails, [link xpath_exception] is thrown if exception handling is not disabled (see <<xpath.errors>> for details). After the query is created, you can query the type of the evaluation result using the following function:
+
+[source]
+----
+xpath_value_type xpath_query::return_type() const;
+----
+
+[#xpath_query::evaluate_boolean][#xpath_query::evaluate_number][#xpath_query::evaluate_string][#xpath_query::evaluate_node_set][#xpath_query::evaluate_node]
+You can evaluate the query using one of the following functions:
+
+[source]
+----
+bool xpath_query::evaluate_boolean(const xpath_node& n) const;
+double xpath_query::evaluate_number(const xpath_node& n) const;
+string_t xpath_query::evaluate_string(const xpath_node& n) const;
+xpath_node_set xpath_query::evaluate_node_set(const xpath_node& n) const;
+xpath_node xpath_query::evaluate_node(const xpath_node& n) const;
+----
+
+All functions take the context node as an argument, compute the expression and return the result, converted to the requested type. According to XPath specification, value of any type can be converted to boolean, number or string value, but no type other than node set can be converted to node set. Because of this, `evaluate_boolean`, `evaluate_number` and `evaluate_string` always return a result, but `evaluate_node_set` and `evaluate_node` result in an error if the return type is not node set (see <<xpath.errors>>).
+
+NOTE: Calling `node.select_nodes("query")` is equivalent to calling `xpath_query("query").evaluate_node_set(node)`. Calling `node.select_node("query")` is equivalent to calling `xpath_query("query").evaluate_node(node)`.
+
+[#xpath_query::evaluate_string_buffer]
+Note that `evaluate_string` function returns the STL string; as such, it's not available in [link PUGIXML_NO_STL] mode and also usually allocates memory. There is another string evaluation function:
+
+[source]
+----
+size_t xpath_query::evaluate_string(char_t* buffer, size_t capacity, const xpath_node& n) const;
+----
+
+This function evaluates the string, and then writes the result to `buffer` (but at most `capacity` characters); then it returns the full size of the result in characters, including the terminating zero. If `capacity` is not 0, the resulting buffer is always zero-terminated. You can use this function as follows: 
+
+* First call the function with `buffer = 0` and `capacity = 0`; then allocate the returned amount of characters, and call the function again, passing the allocated storage and the amount of characters;
+* First call the function with small buffer and buffer capacity; then, if the result is larger than the capacity, the output has been trimmed, so allocate a larger buffer and call the function again.
+
+This is an example of using query objects (link:samples/xpath_query.cpp[]):
+
+[source,indent=0]
+----
+include::samples/xpath_query.cpp[tags=code] 
+----
+
+[[xpath.variables]]
+=== Using variables
+
+XPath queries may contain references to variables; this is useful if you want to use queries that depend on some dynamic parameter without manually preparing the complete query string, or if you want to reuse the same query object for similar queries.
+
+Variable references have the form '''<code><phrase role="identifier">$name</phrase></code>'''; in order to use them, you have to provide a variable set, which includes all variables present in the query with correct types. This set is passed to `xpath_query` constructor or to `select_nodes`/`select_node` functions:
+
+[source]
+----
+explicit xpath_query::xpath_query(const char_t* query, xpath_variable_set* variables = 0);
+xpath_node xml_node::select_node(const char_t* query, xpath_variable_set* variables = 0) const;
+xpath_node_set xml_node::select_nodes(const char_t* query, xpath_variable_set* variables = 0) const;
+----
+
+If you're using query objects, you can change the variable values before `evaluate`/`select` calls to change the query behavior.
+
+NOTE: The variable set pointer is stored in the query object; you have to ensure that the lifetime of the set exceeds that of query object.
+
+[#xpath_variable_set]
+Variable sets correspond to `xpath_variable_set` type, which is essentially a variable container.
+
+[#xpath_variable_set::add]
+You can add new variables with the following function:
+
+[source]
+----
+xpath_variable* xpath_variable_set::add(const char_t* name, xpath_value_type type);
+----
+
+The function tries to add a new variable with the specified name and type; if the variable with such name does not exist in the set, the function adds a new variable and returns the variable handle; if there is already a variable with the specified name, the function returns the variable handle if variable has the specified type. Otherwise the function returns null pointer; it also returns null pointer on allocation failure.
+
+New variables are assigned the default value which depends on the type: `0` for numbers, `false` for booleans, empty string for strings and empty set for node sets.
+
+[#xpath_variable_set::get]
+You can get the existing variables with the following functions:
+
+[source]
+----
+xpath_variable* xpath_variable_set::get(const char_t* name);
+const xpath_variable* xpath_variable_set::get(const char_t* name) const;
+----
+
+The functions return the variable handle, or null pointer if the variable with the specified name is not found.
+
+[#xpath_variable_set::set]
+Additionally, there are the helper functions for setting the variable value by name; they try to add the variable with the corresponding type, if it does not exist, and to set the value. If the variable with the same name but with different type is already present, they return `false`; they also return `false` on allocation failure. Note that these functions do not perform any type conversions.
+
+[source]
+----
+bool xpath_variable_set::set(const char_t* name, bool value);
+bool xpath_variable_set::set(const char_t* name, double value);
+bool xpath_variable_set::set(const char_t* name, const char_t* value);
+bool xpath_variable_set::set(const char_t* name, const xpath_node_set& value);
+----
+
+The variable values are copied to the internal variable storage, so you can modify or destroy them after the functions return.
+
+[#xpath_variable]
+If setting variables by name is not efficient enough, or if you have to inspect variable information or get variable values, you can use variable handles. A variable corresponds to the `xpath_variable` type, and a variable handle is simply a pointer to `xpath_variable`.
+
+[#xpath_variable::type][#xpath_variable::name]
+In order to get variable information, you can use one of the following functions:
+
+[source]
+----
+const char_t* xpath_variable::name() const;
+xpath_value_type xpath_variable::type() const;
+----
+
+Note that each variable has a distinct type which is specified upon variable creation and can not be changed later.
+
+[#xpath_variable::get_boolean][#xpath_variable::get_number][#xpath_variable::get_string][#xpath_variable::get_node_set]
+In order to get variable value, you should use one of the following functions, depending on the variable type:
+
+[source]
+----
+bool xpath_variable::get_boolean() const;
+double xpath_variable::get_number() const;
+const char_t* xpath_variable::get_string() const;
+const xpath_node_set& xpath_variable::get_node_set() const;
+----
+
+These functions return the value of the variable. Note that no type conversions are performed; if the type mismatch occurs, a dummy value is returned (`false` for booleans, `NaN` for numbers, empty string for strings and empty set for node sets).
+
+[#xpath_variable::set]
+In order to set variable value, you should use one of the following functions, depending on the variable type:
+
+[source]
+----
+bool xpath_variable::set(bool value);
+bool xpath_variable::set(double value);
+bool xpath_variable::set(const char_t* value);
+bool xpath_variable::set(const xpath_node_set& value);
+----
+
+These functions modify the variable value. Note that no type conversions are performed; if the type mismatch occurs, the functions return `false`; they also return `false` on allocation failure. The variable values are copied to the internal variable storage, so you can modify or destroy them after the functions return.
+
+This is an example of using variables in XPath queries (link:samples/xpath_variables.cpp[]):

+
+[[xpath.errors]]
+=== Error handling
+
+There are two different mechanisms for error handling in XPath implementation; the mechanism used depends on whether exception support is disabled (this is controlled with [link PUGIXML_NO_EXCEPTIONS] define).
+
+[#xpath_exception]
+[#xpath_exception::result]
+[#xpath_exception::what]
+By default, XPath functions throw `xpath_exception` object in case of errors; additionally, in the event any memory allocation fails, an `std::bad_alloc` exception is thrown. Also `xpath_exception` is thrown if the query is evaluated to a node set, but the return type is not node set. If the query constructor succeeds (i.e. no exception is thrown), the query object is valid. Otherwise you can get the error details via one of the following functions:
+
+[source]
+----
+virtual const char* xpath_exception::what() const throw();
+const xpath_parse_result& xpath_exception::result() const;
+----
+
+[#xpath_query::unspecified_bool_type]
+[#xpath_query::result]
+If exceptions are disabled, then in the event of parsing failure the query is initialized to invalid state; you can test if the query object is valid by using it in a boolean expression: `if (query) { ... }`. Additionally, you can get parsing result via the result() accessor:
+
+[source]
+----
+const xpath_parse_result& xpath_query::result() const;
+----
+    
+Without exceptions, evaluating invalid query results in `false`, empty string, NaN or an empty node set, depending on the type; evaluating a query as a node set results in an empty node set if the return type is not node set.
+
+[#xpath_parse_result]
+The information about parsing result is returned via `xpath_parse_result` object. It contains parsing status and the offset of last successfully parsed character from the beginning of the source stream:
+
+[source]
+----
+struct xpath_parse_result
+{
+    const char* error;
+    ptrdiff_t offset;
+
+    operator bool() const;
+    const char* description() const;
+};
+----
+
+[#xpath_parse_result::error]
+Parsing result is represented as the error message; it is either a null pointer, in case there is no error, or the error message in the form of ASCII zero-terminated string.
+
+[#xpath_parse_result::description]
+`description()` member function can be used to get the error message; it never returns the null pointer, so you can safely use `description()` even if query parsing succeeded. Note that `description()` returns a `char` string even in `PUGIXML_WCHAR_MODE`; you'll have to call [link as_wide] to get the `wchar_t` string.
+
+[#xpath_parse_result::offset]
+In addition to the error message, parsing result has an `offset` member, which contains the offset of last successfully parsed character. This offset is in units of [link char_t pugi::char_t] (bytes for character mode, wide characters for wide character mode).
+
+[#xpath_parse_result::bool]
+Parsing result object can be implicitly converted to `bool` like this: `if (result) { ... } else { ... }`.
+
+This is an example of XPath error handling (link:samples/xpath_error.cpp[]):
+
+[source,indent=0]
+----
+include::samples/xpath_error.cpp[tags=code] 
+----
+
+[[xpath.w3c]]
+=== Conformance to W3C specification
+
+Because of the differences in document object models, performance considerations and implementation complexity, pugixml does not provide a fully conformant XPath 1.0 implementation. This is the current list of incompatibilities:
+
+* Consecutive text nodes sharing the same parent are not merged, i.e. in `<node>text1 <![CDATA[data]]> text2</node>` node should have one text node child, but instead has three.
+* Since the document type declaration is not used for parsing, `id()` function always returns an empty node set.
+* Namespace nodes are not supported (affects namespace:: axis).
+* Name tests are performed on QNames in XML document instead of expanded names; for `<foo xmlns:ns1='uri' xmlns:ns2='uri'><ns1:child/><ns2:child/></foo>`, query `foo/ns1:*` will return only the first child, not both of them. Compliant XPath implementations can return both nodes if the user provides appropriate namespace declarations.
+* String functions consider a character to be either a single `char` value or a single `wchar_t` value, depending on the library configuration; this means that some string functions are not fully Unicode-aware. This affects `substring()`, `string-length()` and `translate()` functions.

+    # Memory allocation errors during parsing now preserve last parsed offset (to give an idea about parsing progress)
+    # If an element node has the only child, and it is of CDATA type, then the extra indentation is omitted (previously this behavior only held for PCDATA children)
+
+* Additional functionality:
+    # Added xml_parse_result default constructor
+    # Added xml_document::load_file and xml_document::save_file with wide character paths
+    # Added as_utf8 and as_wide overloads for std::wstring/std::string arguments
+    # Added DOCTYPE node type (node_doctype) and a special parse flag, parse_doctype, to add such nodes to the document during parsing
+    # Added parse_full parse flag mask, which extends parse_default with all node type parsing flags except parse_ws_pcdata
+    # Added xml_node::hash_value() and xml_attribute::hash_value() functions for use in hash-based containers
+    # Added internal_object() and additional constructor for both xml_node and xml_attribute for easier marshalling (useful for language bindings)
+    # Added xml_document::document_element() function
+    # Added xml_node::prepend_attribute, xml_node::prepend_child and xml_node::prepend_copy functions
+    # Added xml_node::append_child, xml_node::prepend_child, xml_node::insert_child_before and xml_node::insert_child_after overloads for element nodes (with name instead of type)
+    # Added xml_document::reset() function
+
+* Performance improvements:
+    # xml_node::root() and xml_node::offset_debug() are now O(1) instead of O(logN)
+    # Minor parsing optimizations
+    # Minor memory optimization for strings in DOM tree (set_name/set_value)
+    # Memory optimization for string memory reclaiming in DOM tree (set_name/set_value now reallocate the buffer if memory waste is too big)
+    # XPath: optimized document order sorting
+    # XPath: optimized child/attribute axis step
+    # XPath: optimized number-to-string conversions in MSVC
+    # XPath: optimized concat for many arguments
+    # XPath: optimized evaluation allocation mechanism: constant and document strings are not heap-allocated
+    # XPath: optimized evaluation allocation mechanism: all temporaries' allocations use fast stack-like allocator
+
+* Compatibility:
+    # Removed wildcard functions (xml_node::child_w, xml_node::attribute_w, etc.)
+    # Removed xml_node::all_elements_by_name
+    # Removed xpath_type_t enumeration; use xpath_value_type instead
+    # Removed format_write_bom_utf8 enumeration; use format_write_bom instead
+    # Removed xml_document::precompute_document_order, xml_attribute::document_order and xml_node::document_order functions; document order sort optimization is now automatic
+    # Removed xml_document::parse functions and transfer_ownership struct; use xml_document::load_buffer_inplace and xml_document::load_buffer_inplace_own instead
+    # Removed as_utf16 function; use as_wide instead
+
+[h5 1.07.2010 - version 0.9]
+
+Major release, featuring extended and improved Unicode support, miscellaneous performance improvements, bug fixes and more.
+
+* Major Unicode improvements:
+    # Introduced encoding support (automatic/manual encoding detection on load, manual encoding selection on save, conversion from/to UTF8, UTF16 LE/BE, UTF32 LE/BE)
+    # Introduced wchar_t mode (you can set PUGIXML_WCHAR_MODE define to switch pugixml internal encoding from UTF8 to wchar_t; all functions are switched to their Unicode variants)
+    # Load/save functions now support wide streams
+
+* Bug fixes:
+    # Fixed document corruption on failed parsing bug
+    # XPath string <-> number conversion improvements (increased precision, fixed crash for huge numbers)
+    # Improved DOCTYPE parsing: now parser recognizes all well-formed DOCTYPE declarations
+    # Fixed xml_attribute::as_uint() for large numbers (i.e. 2^32-1)
+    # Fixed xml_node::first_element_by_path for path components that are prefixes of node names, but are not exactly equal to them.
+
+* Specification changes:
+    # parse() API changed to load_buffer/load_buffer_inplace/load_buffer_inplace_own; load_buffer APIs do not require zero-terminated strings.
+    # Renamed as_utf16 to as_wide
+    # Changed xml_node::offset_debug return type and xml_parse_result::offset type to ptrdiff_t
+    # Nodes/attributes with empty names are now printed as :anonymous
+
+* Performance improvements:
+    # Optimized document parsing and saving
+    # Changed internal memory management: internal allocator is used for both metadata and name/value data; allocated pages are deleted if all allocations from them are deleted
+    # Optimized memory consumption: sizeof(xml_node_struct) reduced from 40 bytes to 32 bytes on x86
+    # Optimized debug mode parsing/saving by order of magnitude
+
+* Miscellaneous:
+    # All STL includes except <exception> in pugixml.hpp are replaced with forward declarations
+    # xml_node::remove_child and xml_node::remove_attribute now return the operation result
+
+* Compatibility:
+    # parse() and as_utf16 are left for compatibility (these functions are deprecated and will be removed in version 1.0)
+    # Wildcard functions, document_order/precompute_document_order functions, all_elements_by_name function and format_write_bom_utf8 flag are deprecated and will be removed in version 1.0
+    # xpath_type_t enumeration was renamed to xpath_value_type; xpath_type_t is deprecated and will be removed in version 1.0
+
+[h5 8.11.2009 - version 0.5]
+
+Major bugfix release. Changes:
+
+* XPath bugfixes:
+    # Fixed translate(), lang() and concat() functions (infinite loops/crashes)
+    # Fixed compilation of queries with empty literal strings ("")
+    # Fixed axis tests: they never add empty nodes/attributes to the resulting node set now
+    # Fixed string-value evaluation for node-set (the result excluded some text descendants)
+    # Fixed self:: axis (it behaved like ancestor-or-self::)
+    # Fixed following:: and preceding:: axes (they included descendent and ancestor nodes, respectively)
+    # Minor fix for namespace-uri() function (namespace declaration scope includes the parent element of namespace declaration attribute)
+    # Some incorrect queries are no longer parsed now (i.e. foo: *)
+    # Fixed text()/etc. node test parsing bug (i.e. foo[text()] failed to compile)
+    # Fixed root step (/) - it now selects empty node set if query is evaluated on empty node
+    # Fixed string to number conversion ("123 " converted to NaN, "123 .456" converted to 123.456 - now the results are 123 and NaN, respectively)
+    # Node set copying now preserves sorted type; leads to better performance on some queries
+
+* Miscellaneous bugfixes:
+    # Fixed xml_node::offset_debug for PI nodes
+    # Added empty attribute checks to xml_node::remove_attribute
+    # Fixed node_pi and node_declaration copying
+    # Const-correctness fixes
+
+* Specification changes:
+    # xpath_node::select_nodes() and related functions now throw exception if expression return type is not node set (instead of assertion)
+    # xml_node::traverse() now sets depth to -1 for both begin() and end() callbacks (was 0 at begin() and -1 at end())
+    # In case of non-raw node printing a newline is output after PCDATA inside nodes if the PCDATA has siblings
+    # UTF8 -> wchar_t conversion now considers 5-byte UTF8-like sequences as invalid
+
+* New features:
+    # Added xpath_node_set::operator[] for index-based iteration
+    # Added xpath_query::return_type()
+    # Added getter accessors for memory-management functions
+
+[h5 17.09.2009 - version 0.42]
+
+Maintenance release. Changes:
+
+* Bug fixes:
+    # Fixed deallocation in case of custom allocation functions or if delete[] / free are incompatible
+    # XPath parser fixed for incorrect queries (i.e. incorrect XPath queries should now always fail to compile)
+    # Const-correctness fixes for find_child_by_attribute
+    # Improved compatibility (miscellaneous warning fixes, fixed cstring include dependency for GCC)
+    # Fixed iterator begin/end and print function to work correctly for empty nodes
+
+* New features:
+    # Added PUGIXML_API/PUGIXML_CLASS/PUGIXML_FUNCTION configuration macros to control class/function attributes
+    # Added xml_attribute::set_value overloads for different types
+
+[h5 8.02.2009 - version 0.41]
+
+Maintenance release. Changes:
+
+* Bug fixes:
+    # Fixed bug with node printing (occasionally some content was not written to output stream)
+
+[h5 18.01.2009 - version 0.4]
+
+Changes:
+
+* Bug fixes:
+    # Documentation fix in samples for parse() with manual lifetime control
+    # Fixed document order sorting in XPath (it caused wrong order of nodes after xpath_node_set::sort and wrong results of some XPath queries)
+
+* Node printing changes:
+    # Single quotes are no longer escaped when printing nodes
+    # Symbols in second half of ASCII table are no longer escaped when printing nodes; because of this, format_utf8 flag is deleted as it's no longer needed and format_write_bom is renamed to format_write_bom_utf8.
+    # Reworked node printing - now it works via xml_writer interface; implementations for FILE* and std::ostream are available. As a side-effect, xml_document::save_file now works without STL.
+
+* New features:
+    # Added unsigned integer support for attributes (xml_attribute::as_uint, xml_attribute::operator=)
+    # Now document declaration (<?xml ...?>) is parsed as node with type node_declaration when parse_declaration flag is specified (access to encoding/version is performed as if they were attributes, i.e. doc.child("xml").attribute("version").as_float()); corresponding flags for node printing were also added
+    # Added support for custom memory management (see set_memory_management_functions for details)
+    # Implemented node/attribute copying (see xml_node::insert_copy_* and xml_node::append_copy for details)
+    # Added find_child_by_attribute and find_child_by_attribute_w to simplify parsing code in some cases (i.e. COLLADA files)
+    # Added file offset information querying for debugging purposes (now you're able to determine exact location of any xml_node in parsed file, see xml_node::offset_debug for details)
+    # Improved error handling for parsing - now load(), load_file() and parse() return xml_parse_result, which contains error code and last parsed offset; this does not break old interface as xml_parse_result can be implicitly casted to bool.
+
+[h5 31.10.2007 - version 0.34]
+
+Maintenance release. Changes:
+
+* Bug fixes:
+    # Fixed bug with loading from text-mode iostreams
+    # Fixed leak when transfer_ownership is true and parsing is failing
+    # Fixed bug in saving (\r and \n are now escaped in attribute values)
+    # Renamed free() to destroy() - some macro conflicts were reported
+
+* New features:
+    # Improved compatibility (supported Digital Mars C{plus}{plus}, MSVC 6, CodeWarrior 8, PGI C{plus}{plus}, Comeau, supported PS3 and XBox360)
+    # PUGIXML_NO_EXCEPTION flag for platforms without exception handling
+
+[h5 21.02.2007 - version 0.3]
+
+Refactored, reworked and improved version. Changes:
+
+* Interface:
+    # Added XPath
+    # Added tree modification functions
+    # Added no STL compilation mode
+    # Added saving document to file
+    # Refactored parsing flags
+    # Removed xml_parser class in favor of xml_document
+    # Added transfer ownership parsing mode
+    # Modified the way xml_tree_walker works
+    # Iterators are now non-constant
+
+* Implementation:
+    # Support of several compilers and platforms
+    # Refactored and sped up parsing core
+    # Improved standard compliancy
+    # Added XPath implementation
+    # Fixed several bugs
+
+[h5 6.11.2006 - version 0.2]
+
+First public release. Changes:
+
+* Bug fixes:
+    # Fixed child_value() (for empty nodes)
+    # Fixed xml_parser_impl warning at W4
+
+* New features:
+    # Introduced child_value(name) and child_value_w(name)
+    # parse_eol_pcdata and parse_eol_attribute flags + parse_minimal optimizations
+    # Optimizations of strconv_t
+

+= pugixml {version} quick start guide

+
+[[introduction]]
+== Introduction
+
+http://pugixml.org/[pugixml] is a light-weight C{plus}{plus} XML processing library. It consists of a DOM-like interface with rich traversal/modification capabilities, an extremely fast XML parser which constructs the DOM tree from an XML file/buffer, and an XPath 1.0 implementation for complex data-driven tree queries. Full Unicode support is also available, with two Unicode interface variants and conversions between different Unicode encodings (which happen automatically during parsing/saving). The library is extremely portable and easy to integrate and use. pugixml is developed and maintained since 2006 and has many users. All code is distributed under the <<license,MIT license>>, making it completely free to use in both open-source and proprietary applications.
+
+pugixml enables very fast, convenient and memory-efficient XML document processing. However, since pugixml has a DOM parser, it can't process XML documents that do not fit in memory; also the parser is a non-validating one, so if you need DTD/Schema validation, the library is not for you.
+
+This is the quick start guide for pugixml, which purpose is to enable you to start using the library quickly. Many important library features are either not described at all or only mentioned briefly; for more complete information you link:manual.html[should read the complete manual].
+
+NOTE: No documentation is perfect; neither is this one. If you encounter a description that is unclear, a statement that is incorrect or a syntactic error, please file an issue as described in <<feedback>>.
+
+[[install]]
+== Installation
+
+pugixml is distributed in source form. You can download a source distribution via one of the following links:
+
+* https://github.com/zeux/pugixml/releases/download/v{version}/pugixml-{version}.zip
+* https://github.com/zeux/pugixml/releases/download/v{version}/pugixml-{version}.tar.gz
+
+The distribution contains library source, documentation (the guide you're reading now and the manual) and some code examples. After downloading the distribution, install pugixml by extracting all files from the compressed archive. The files have different line endings depending on the archive format - `.zip` archive has Windows line endings, `.tar.gz` archive has Unix line endings. Otherwise the files in both archives are identical.
+
+The complete pugixml source consists of three files - one source file, `pugixml.cpp`, and two header files, `pugixml.hpp` and `pugiconfig.hpp`. `pugixml.hpp` is the primary header which you need to include in order to use pugixml classes/functions. The rest of this guide assumes that `pugixml.hpp` is either in the current directory or in one of include directories of your projects, so that `#include "pugixml.hpp"` can find the header; however you can also use relative path (i.e. `#include "../libs/pugixml/src/pugixml.hpp"`) or include directory-relative path (i.e. `#include <xml/thirdparty/pugixml/src/pugixml.hpp>`).
+ 
+The easiest way to build pugixml is to compile the source file, `pugixml.cpp`, along with the existing library/executable. This process depends on the method of building your application; for example, if you're using Microsoft Visual Studio footnote:[All trademarks used are properties of their respective owners.], Apple Xcode, Code::Blocks or any other IDE, just add `pugixml.cpp` to one of your projects. There are other building methods available, including building pugixml as a standalone static/shared library; link:manual/install.html#install.building[read the manual] for further information.
+
+[[dom]]
+== Document object model
+
+pugixml stores XML data in DOM-like way: the entire XML document (both document structure and element data) is stored in memory as a tree. The tree can be loaded from character stream (file, string, C{plus}{plus} I/O stream), then traversed via special API or XPath expressions. The whole tree is mutable: both node structure and node/attribute data can be changed at any time. Finally, the result of document transformations can be saved to a character stream (file, C{plus}{plus} I/O stream or custom transport).
+
+The root of the tree is the document itself, which corresponds to C{plus}{plus} type `xml_document`. Document has one or more child nodes, which correspond to C{plus}{plus} type `xml_node`. Nodes have different types; depending on a type, a node can have a collection of child nodes, a collection of attributes, which correspond to C{plus}{plus} type `xml_attribute`, and some additional data (i.e. name).
+
+The most common node types are:
+
+* Document node (`node_document`) - this is the root of the tree, which consists of several child nodes. This node corresponds to `xml_document` class; note that `xml_document` is a sub-class of `xml_node`, so the entire node interface is also available.
+
+* Element/tag node (`node_element`) - this is the most common type of node, which represents XML elements. Element nodes have a name, a collection of attributes and a collection of child nodes (both of which may be empty). The attribute is a simple name/value pair.
+
+* Plain character data nodes (`node_pcdata`) represent plain text in XML. PCDATA nodes have a value, but do not have name or children/attributes. Note that *plain character data is not a part of the element node but instead has its own node*; for example, an element node can have several child PCDATA nodes.
+
+Despite the fact that there are several node types, there are only three C{plus}{plus} types representing the tree (`xml_document`, `xml_node`, `xml_attribute`); some operations on `xml_node` are only valid for certain node types. They are described below.
+
+NOTE: All pugixml classes and functions are located in `pugi` namespace; you have to either use explicit name qualification (i.e. `pugi::xml_node`), or to gain access to relevant symbols via `using` directive (i.e. `using pugi::xml_node;` or `using namespace pugi;`).
+
+`xml_document` is the owner of the entire document structure; destroying the document destroys the whole tree. The interface of `xml_document` consists of loading functions, saving functions and the entire interface of `xml_node`, which allows for document inspection and/or modification. Note that while `xml_document` is a sub-class of `xml_node`, `xml_node` is not a polymorphic type; the inheritance is present only to simplify usage.
+
+`xml_node` is the handle to document node; it can point to any node in the document, including document itself. There is a common interface for nodes of all types. Note that `xml_node` is only a handle to the actual node, not the node itself - you can have several `xml_node` handles pointing to the same underlying object. Destroying `xml_node` handle does not destroy the node and does not remove it from the tree.
+
+There is a special value of `xml_node` type, known as null node or empty node. It does not correspond to any node in any document, and thus resembles null pointer. However, all operations are defined on empty nodes; generally the operations don't do anything and return empty nodes/attributes or empty strings as their result. This is useful for chaining calls; i.e. you can get the grandparent of a node like so: `node.parent().parent()`; if a node is a null node or it does not have a parent, the first `parent()` call returns null node; the second `parent()` call then also returns null node, so you don't have to check for errors twice. You can test if a handle is null via implicit boolean cast: `if (node) { ... }` or `if (!node) { ... }`.
+
+`xml_attribute` is the handle to an XML attribute; it has the same semantics as `xml_node`, i.e. there can be several `xml_attribute` handles pointing to the same underlying object and there is a special null attribute value, which propagates to function results.
+
+There are two choices of interface and internal representation when configuring pugixml: you can either choose the UTF-8 (also called char) interface or UTF-16/32 (also called wchar_t) one. The choice is controlled via `PUGIXML_WCHAR_MODE` define; you can set it via `pugiconfig.hpp` or via preprocessor options. All tree functions that work with strings work with either C-style null terminated strings or STL strings of the selected character type. link:manual/dom.html#dom.unicode[Read the manual] for additional information on Unicode interface.
+
+[[loading]]
+== Loading document
+
+pugixml provides several functions for loading XML data from various places - files, C{plus}{plus} iostreams, memory buffers. All functions use an extremely fast non-validating parser. This parser is not fully W3C conformant - it can load any valid XML document, but does not perform some well-formedness checks. While considerable effort is made to reject invalid XML documents, some validation is not performed because of performance reasons. XML data is always converted to internal character format before parsing. pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it's a strict subset of UTF-16) and handles all encoding conversions automatically.
+
+The most common source of XML data is files; pugixml provides a separate function for loading XML document from file. This function accepts file path as its first argument, and also two optional arguments, which specify parsing options and input data encoding, which are described in the manual.
+
+This is an example of loading XML document from file (link:samples/load_file.cpp[]):
+
+[source,indent=0]
+----
+include::samples/load_file.cpp[tags=code] 
+----
+
+`load_file`, as well as other loading functions, destroys the existing document tree and then tries to load the new tree from the specified file. The result of the operation is returned in an `xml_parse_result` object; this object contains the operation status, and the related information (i.e. last successfully parsed position in the input file, if parsing fails).
+
+Parsing result object can be implicitly converted to `bool`; if you do not want to handle parsing errors thoroughly, you can just check the return value of load functions as if it was a `bool`: `if (doc.load_file("file.xml")) { ... } else { ... }`. Otherwise you can use the `status` member to get parsing status, or the `description()` member function to get the status in a string form.
+
+This is an example of handling loading errors (link:samples/load_error_handling.cpp[]):
+
+[source,indent=0]
+----
+include::samples/load_error_handling.cpp[tags=code] 
+----
+
+Sometimes XML data should be loaded from some other source than file, i.e. HTTP URL; also you may want to load XML data from file using non-standard functions, i.e. to use your virtual file system facilities or to load XML from gzip-compressed files. These scenarios either require loading document from memory, in which case you should prepare a contiguous memory block with all XML data and to pass it to one of buffer loading functions, or loading document from C{plus}{plus} IOstream, in which case you should provide an object which implements `std::istream` or `std::wistream` interface.
+
+There are different functions for loading document from memory; they treat the passed buffer as either an immutable one (`load_buffer`), a mutable buffer which is owned by the caller (`load_buffer_inplace`), or a mutable buffer which ownership belongs to pugixml (`load_buffer_inplace_own`). There is also a simple helper function, `xml_document::load`, for cases when you want to load the XML document from null-terminated character string.
+
+This is an example of loading XML document from memory using one of these functions (link:samples/load_memory.cpp[]); read the sample code for more examples:
+
+[source,indent=0]
+----
+include::samples/load_memory.cpp[tags=decl]

+----
+include::samples/load_memory.cpp[tags=load_buffer_inplace_begin]
+
+include::samples/load_memory.cpp[tags=load_buffer_inplace_end]
+----
+
+This is a simple example of loading XML document from file using streams (link:samples/load_stream.cpp[]); read the sample code for more complex examples involving wide streams and locales:
+
+[source,indent=0]
+----
+include::samples/load_stream.cpp[tags=code]
+----
+
+[[access]]
+== Accessing document data
+
+pugixml features an extensive interface for getting various types of data from the document and for traversing the document. You can use various accessors to get node/attribute data, you can traverse the child node/attribute lists via accessors or iterators, you can do depth-first traversals with `xml_tree_walker` objects, and you can use XPath for complex data-driven queries.
+
+You can get node or attribute name via `name()` accessor, and value via `value()` accessor. Note that both functions never return null pointers - they either return a string with the relevant content, or an empty string if name/value is absent or if the handle is null. Also there are two notable things for reading values:
+
+* It is common to store data as text contents of some node - i.e. `<node><description>This is a node</description></node>`. In this case, `<description>` node does not have a value, but instead has a child of type `node_pcdata` with value `"This is a node"`. pugixml provides `child_value()` and `text()` helper functions to parse such data.
+
+* In many cases attribute values have types that are not strings - i.e. an attribute may always contain values that should be treated as integers, despite the fact that they are represented as strings in XML. pugixml provides several accessors that convert attribute value to some other type.
+
+This is an example of using these functions (link:samples/traverse_base.cpp[]):
+
+[source,indent=0]
+----
+include::samples/traverse_base.cpp[tags=data]
+----
+
+Since a lot of document traversal consists of finding the node/attribute with the correct name, there are special functions for that purpose. For example, `child("Tool")` returns the first node which has the name `"Tool"`, or null handle if there is no such node. This is an example of using such functions (link:samples/traverse_base.cpp[]):
+
+[source,indent=0]
+----
+include::samples/traverse_base.cpp[tags=contents]
+----
+
+Child node lists and attribute lists are simply double-linked lists; while you can use `previous_sibling`/`next_sibling` and other such functions for iteration, pugixml additionally provides node and attribute iterators, so that you can treat nodes as containers of other nodes or attributes. All iterators are bidirectional and support all usual iterator operations. The iterators are invalidated if the node/attribute objects they're pointing to are removed from the tree; adding nodes/attributes does not invalidate any iterators.
+
+Here is an example of using iterators for document traversal (link:samples/traverse_iter.cpp[]):
+
+[source,indent=0]
+----
+include::samples/traverse_iter.cpp[tags=code]
+----
+
+If your C{plus}{plus} compiler supports range-based for-loop (this is a C{plus}{plus}11 feature, at the time of writing it's supported by Microsoft Visual Studio 11 Beta, GCC 4.6 and Clang 3.0), you can use it to enumerate nodes/attributes. Additional helpers are provided to support this; note that they are also compatible with http://www.boost.org/libs/foreach/[Boost Foreach], and possibly other pre-C{plus}{plus}11 foreach facilities.
+
+Here is an example of using C{plus}{plus}11 range-based for loop for document traversal (link:samples/traverse_rangefor.cpp[]):
+
+[source,indent=0]
+----
+include::samples/traverse_rangefor.cpp[tags=code]
+----
+
+The methods described above allow traversal of immediate children of some node; if you want to do a deep tree traversal, you'll have to do it via a recursive function or some equivalent method. However, pugixml provides a helper for depth-first traversal of a subtree. In order to use it, you have to implement `xml_tree_walker` interface and to call `traverse` function.
+
+This is an example of traversing tree hierarchy with xml_tree_walker (link:samples/traverse_walker.cpp[]):
+
+[source,indent=0]
+----
+include::samples/traverse_walker.cpp[tags=impl]
+----
+[source,indent=0]
+----
+include::samples/traverse_walker.cpp[tags=traverse]
+----
+
+Finally, for complex queries often a higher-level DSL is needed. pugixml provides an implementation of XPath 1.0 language for such queries. The complete description of XPath usage can be found in the manual, but here are some examples:
+
+[source,indent=0]
+----
+include::samples/xpath_select.cpp[tags=code]
+----
+
+CAUTION: XPath functions throw `xpath_exception` objects on error; the sample above does not catch these exceptions.
+
+[[modify]]
+== Modifying document data
+
+The document in pugixml is fully mutable: you can completely change the document structure and modify the data of nodes/attributes. All functions take care of memory management and structural integrity themselves, so they always result in structurally valid tree - however, it is possible to create an invalid XML tree (for example, by adding two attributes with the same name or by setting attribute/node name to empty/invalid string). Tree modification is optimized for performance and for memory consumption, so if you have enough memory you can create documents from scratch with pugixml and later save them to file/stream instead of relying on error-prone manual text writing and without too much overhead.
+
+All member functions that change node/attribute data or structure are non-constant and thus can not be called on constant handles. However, you can easily convert constant handle to non-constant one by simple assignment: `void foo(const pugi::xml_node& n) { pugi::xml_node nc = n; }`, so const-correctness here mainly provides additional documentation.
+
+As discussed before, nodes can have name and value, both of which are strings. Depending on node type, name or value may be absent. You can use `set_name` and `set_value` member functions to set them. Similar functions are available for attributes; however, the `set_value` function is overloaded for some other types except strings, like floating-point numbers. Also, attribute value can be set using an assignment operator. This is an example of setting node/attribute name and value (link:samples/modify_base.cpp[]):
+
+[source,indent=0]
+----
+include::samples/modify_base.cpp[tags=node]
+----
+[source,indent=0]
+----
+include::samples/modify_base.cpp[tags=attr]
+----
+
+Nodes and attributes do not exist without a document tree, so you can't create them without adding them to some document. A node or attribute can be created at the end of node/attribute list or before/after some other node. All insertion functions return the handle to newly created object on success, and null handle on failure. Even if the operation fails (for example, if you're trying to add a child node to PCDATA node), the document remains in consistent state, but the requested node/attribute is not added.
+
+CAUTION: `attribute()` and `child()` functions do not add attributes or nodes to the tree, so code like `node.attribute("id") = 123;` will not do anything if `node` does not have an attribute with name `"id"`. Make sure you're operating with existing attributes/nodes by adding them if necessary.
+
+This is an example of adding new attributes/nodes to the document (link:samples/modify_add.cpp[]):
+
+[source,indent=0]
+----
+include::samples/modify_add.cpp[tags=code]
+----
+
+If you do not want your document to contain some node or attribute, you can remove it with `remove_attribute` and `remove_child` functions. Removing the attribute or node invalidates all handles to the same underlying object, and also invalidates all iterators pointing to the same object. Removing node also invalidates all past-the-end iterators to its attribute or child node list. Be careful to ensure that all such handles and iterators either do not exist or are not used after the attribute/node is removed.
+
+This is an example of removing attributes/nodes from the document (link:samples/modify_remove.cpp[]):
+
+[source,indent=0]
+----
+include::samples/modify_remove.cpp[tags=code]
+----
+
+[[saving]]
+== Saving document
+
+Often after creating a new document or loading the existing one and processing it, it is necessary to save the result back to file. Also it is occasionally useful to output the whole document or a subtree to some stream; use cases include debug printing, serialization via network or other text-oriented medium, etc. pugixml provides several functions to output any subtree of the document to a file, stream or another generic transport interface; these functions allow to customize the output format, and also perform necessary encoding conversions.
+
+Before writing to the destination the node/attribute data is properly formatted according to the node type; all special XML symbols, such as < and &, are properly escaped. In order to guard against forgotten node/attribute names, empty node/attribute names are printed as `":anonymous"`. For well-formed output, make sure all node and attribute names are set to meaningful values.
+
+If you want to save the whole document to a file, you can use the `save_file` function, which returns `true` on success. This is a simple example of saving XML document to file (link:samples/save_file.cpp[]):
+
+[source,indent=0]
+----
+include::samples/save_file.cpp[tags=code]
+----
+
+To enhance interoperability pugixml provides functions for saving document to any object which implements C{plus}{plus} `std::ostream` interface. This allows you to save documents to any standard C{plus}{plus} stream (i.e. file stream) or any third-party compliant implementation (i.e. Boost Iostreams). Most notably, this allows for easy debug output, since you can use `std::cout` stream as saving target. There are two functions, one works with narrow character streams, another handles wide character ones.
+
+This is a simple example of saving XML document to standard output (link:samples/save_stream.cpp[]):
+
+[source,indent=0]
+----
+include::samples/save_stream.cpp[tags=code]
+----
+
+All of the above saving functions are implemented in terms of writer interface. This is a simple interface with a single function, which is called several times during output process with chunks of document data as input. In order to output the document via some custom transport, for example sockets, you should create an object which implements `xml_writer_file` interface and pass it to `xml_document::save` function.
+
+This is a simple example of custom writer for saving document data to STL string (link:samples/save_custom_writer.cpp[]); read the sample code for more complex examples:
+
+[source,indent=0]
+----
+include::samples/save_custom_writer.cpp[tags=code]
+----
+
+While the previously described functions save the whole document to the destination, it is easy to save a single subtree. Instead of calling `xml_document::save`, just call `xml_node::print` function on the target node. You can save node contents to C{plus}{plus} IOstream object or custom writer in this way. Saving a subtree slightly differs from saving the whole document; link:manual/saving.html#saving.subtree[read the manual] for more information.

-        <a href="http://pugixml.org/" target="_top">pugixml</a> is a light-weight C++ XML
-        processing library. It consists of a DOM-like interface with rich traversal/modification
-        capabilities, an extremely fast XML parser which constructs the DOM tree
-        from an XML file/buffer, and an <a class="link" href="manual/xpath.html" title="XPath">XPath 1.0 implementation</a>
-        for complex data-driven tree queries. Full Unicode support is also available,
-        with <a class="link" href="manual/dom.html#manual.dom.unicode" title="Unicode interface">two Unicode interface variants</a>
-        and conversions between different Unicode encodings (which happen automatically
-        during parsing/saving). The library is <a class="link" href="manual/install.html#manual.install.portability" title="Portability">extremely
-        portable</a> and easy to integrate and use. pugixml is developed and maintained
-        since 2006 and has many users. All code is distributed under the <a class="link" href="manual.html#manual.overview.license" title="License">MIT
-        license</a>, making it completely free to use in both open-source and
-        proprietary applications.
-      </p>
-<p>
-        pugixml enables very fast, convenient and memory-efficient XML document processing.
-        However, since pugixml has a DOM parser, it can't process XML documents that
-        do not fit in memory; also the parser is a non-validating one, so if you
-        need DTD or XML Schema validation, the library is not for you.
-      </p>
-<p>
-        This is the complete manual for pugixml, which describes all features of
-        the library in detail. If you want to start writing code as quickly as possible,
-        you are advised to <a href="quickstart.html" target="_top">read the quick start guide
-        first</a>.

-        If you believe you've found a bug in pugixml (bugs include compilation problems
-        (errors/warnings), crashes, performance degradation and incorrect behavior),
-        please file an issue via <a href="https://github.com/zeux/pugixml/issues/new" target="_top">issue
-        submission form</a>. Be sure to include the relevant information so that
-        the bug can be reproduced: the version of pugixml, compiler version and target
-        architecture, the code that uses pugixml and exhibits the bug, etc.
-      </p>
-<p>
-        Feature requests can be reported the same way as bugs, so if you're missing
-        some functionality in pugixml or if the API is rough in some places and you
-        can suggest an improvement, <a href="https://github.com/zeux/pugixml/issues/new" target="_top">file
-        an issue</a>. However please note that there are many factors when considering
-        API changes (compatibility with previous versions, API redundancy, etc.),
-        so generally features that can be implemented via a small function without
-        pugixml modification are not accepted. However, all rules have exceptions.
-      </p>
-<p>
-        If you have a contribution to pugixml, such as build script for some build
-        system/IDE, or a well-designed set of helper functions, or a binding to some
-        language other than C++, please <a href="https://github.com/zeux/pugixml/issues/new" target="_top">file
-        an issue</a>. You can include the relevant patches as issue attachments.

-      pugixml features an extensive interface for getting various types of data from
-      the document and for traversing the document. This section provides documentation
-      for all such functions that do not modify the tree except for XPath-related
-      functions; see <a class="xref" href="xpath.html" title="XPath"> XPath</a> for XPath reference. As discussed in <a class="xref" href="dom.html#manual.dom.cpp" title="C++ interface"> C++ interface</a>,
-      there are two types of handles to tree data - <a class="link" href="dom.html#xml_node">xml_node</a>
-      and <a class="link" href="dom.html#xml_attribute">xml_attribute</a>. The handles have special
-      null (empty) values which propagate through various functions and thus are
-      useful for writing more concise code; see <a class="link" href="dom.html#node_null">this description</a>
-      for details. The documentation in this section will explicitly state the results
-      of all function in case of null inputs.

-        The internal representation of the document is a tree, where each node has
-        a list of child nodes (the order of children corresponds to their order in
-        the XML representation), and additionally element nodes have a list of attributes,
-        which is also ordered. Several functions are provided in order to let you
-        get from one node in the tree to the other. These functions roughly correspond
-        to the internal representation, and thus are usually building blocks for
-        other methods of traversing (i.e. XPath traversals are based on these functions).

-        If node does not have next/previous sibling (this happens if it is the last/first

-        Apart from structural information (parent, child nodes, attributes), nodes
-        can have name and value, both of which are strings. Depending on node type,
-        name or value may be absent. <a class="link" href="dom.html#node_document">node_document</a>
-        nodes do not have a name or value, <a class="link" href="dom.html#node_element">node_element</a>
-        and <a class="link" href="dom.html#node_declaration">node_declaration</a> nodes always

-        and <a class="link" href="dom.html#node_doctype">node_doctype</a> nodes never have a name
-        but always have a value (it may be empty though), <a class="link" href="dom.html#node_pi">node_pi</a>
-        nodes always have a name and a value (again, value may be empty). In order
-        to get node's name or value, you can use the following functions:
-      </p>
-<pre class="programlisting"><span class="keyword">const</span> <span class="identifier">char_t</span><span class="special">*</span> <span class="identifier">xml_node</span><span class="special">::</span><span class="identifier">name</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>

-</pre>
-<p>
-        In case node does not have a name or value or if the node handle is null,
-        both functions return empty strings - they never return null pointers.
-      </p>
-<a name="xml_node::child_value"></a><p>
-        It is common to store data as text contents of some node - i.e. <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">node</span><span class="special">&gt;&lt;</span><span class="identifier">description</span><span class="special">&gt;</span><span class="identifier">This</span> <span class="identifier">is</span> <span class="identifier">a</span> <span class="identifier">node</span><span class="special">&lt;/</span><span class="identifier">description</span><span class="special">&gt;&lt;/</span><span class="identifier">node</span><span class="special">&gt;</span></code>.
-        In this case, <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">description</span><span class="special">&gt;</span></code> node does not have a value, but instead
-        has a child of type <a class="link" href="dom.html#node_pcdata">node_pcdata</a> with value
-        <code class="computeroutput"><span class="string">"This is a node"</span></code>. pugixml

-        For the above example, calling <code class="computeroutput"><span class="identifier">node</span><span class="special">.</span><span class="identifier">child_value</span><span class="special">(</span><span class="string">"description"</span><span class="special">)</span></code> and <code class="computeroutput"><span class="identifier">description</span><span class="special">.</span><span class="identifier">child_value</span><span class="special">()</span></code> will both produce string <code class="computeroutput"><span class="string">"This is a node"</span></code>. If there is no
-        child with relevant type, or if the handle is null, <code class="computeroutput"><span class="identifier">child_value</span></code>
-        functions return empty string.
-      </p>
-<p>
-        <code class="computeroutput"><span class="identifier">text</span><span class="special">()</span></code>
-        returns a special object that can be used for working with PCDATA contents

-<p>
-        It returns <code class="computeroutput"><span class="identifier">def</span></code> argument if
-        the attribute handle is null. If you do not specify the argument, the function

-        Occasionally the needed node is specified not by the unique name but instead
-        by the value of some attribute; for example, it is common to have node collections
-        with each node having a unique id: <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">group</span><span class="special">&gt;&lt;</span><span class="identifier">item</span> <span class="identifier">id</span><span class="special">=</span><span class="string">"1"</span><span class="special">/&gt;</span> <span class="special">&lt;</span><span class="identifier">item</span> <span class="identifier">id</span><span class="special">=</span><span class="string">"2"</span><span class="special">/&gt;&lt;/</span><span class="identifier">group</span><span class="special">&gt;</span></code>.

-<p>
-        The three-argument function returns the first child node with the specified
-        name which has an attribute with the specified name/value; the two-argument
-        function skips the name test for the node, which can be useful for searching
-        in heterogeneous collections. If the node handle is null or if no node is
-        found, null handle is returned. All string comparisons are case-sensitive.
-      </p>

-        In all of the above functions, all arguments have to be valid strings; passing
-        null pointers results in undefined behavior.

-        <code class="computeroutput"><span class="identifier">begin</span></code> and <code class="computeroutput"><span class="identifier">attributes_begin</span></code>
-        return iterators that point to the first node/attribute, respectively; <code class="computeroutput"><span class="identifier">end</span></code> and <code class="computeroutput"><span class="identifier">attributes_end</span></code>
-        return past-the-end iterator for node/attribute list, respectively - this
-        iterator can't be dereferenced, but decrementing it results in an iterator
-        pointing to the last element in the list (except for empty lists, where decrementing
-        past-the-end iterator results in undefined behavior). Past-the-end iterator
-        is commonly used as a termination value for iteration loops (see sample below).
-        If you want to get an iterator that points to an existing handle, you can
-        construct the iterator with the handle as a single constructor argument,
-        like so: <code class="computeroutput"><span class="identifier">xml_node_iterator</span><span class="special">(</span><span class="identifier">node</span><span class="special">)</span></code>.
-        For <code class="computeroutput"><span class="identifier">xml_attribute_iterator</span></code>,
-        you'll have to provide both an attribute and its parent node.

-<p>
-        <code class="computeroutput"><span class="identifier">begin</span></code> and <code class="computeroutput"><span class="identifier">end</span></code>
-        return equal iterators if called on null node; such iterators can't be dereferenced.
-        <code class="computeroutput"><span class="identifier">attributes_begin</span></code> and <code class="computeroutput"><span class="identifier">attributes_end</span></code> behave the same way. For
-        correct iterator usage this means that child node/attribute collections of
-        null nodes appear to be empty.
-      </p>
-<p>
-        Both types of iterators have bidirectional iterator semantics (i.e. they
-        can be incremented and decremented, but efficient random access is not supported)
-        and support all usual iterator operations - comparison, dereference, etc.
-        The iterators are invalidated if the node/attribute objects they're pointing
-        to are removed from the tree; adding nodes/attributes does not invalidate
-        any iterators.

-<a name="xml_text::get"></a><p>
-        Given a text object, you can get the contents (i.e. the value of PCDATA/CDATA

-        All of the above functions have the same semantics as similar <code class="computeroutput"><span class="identifier">xml_attribute</span></code> members: they return the
-        default argument if the text object is empty, they convert the text contents
-        to a target type using the same rules and restrictions. You can <a class="link" href="access.html#xml_attribute::as_int">refer
-        to documentation for the attribute functions</a> for details.

-<a name="xml_text::data"></a><p>
-        <code class="computeroutput"><span class="identifier">xml_text</span></code> is essentially a
-        helper class that operates on <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        values. It is bound to a node of type <a class="link" href="dom.html#node_pcdata">node_pcdata</a>
-        or <a class="link" href="dom.html#node_cdata">node_cdata</a>. You can use the following
-        function to retrieve this node:

-<p>
-        Essentially, assuming <code class="computeroutput"><span class="identifier">text</span></code>
-        is an <code class="computeroutput"><span class="identifier">xml_text</span></code> object, calling
-        <code class="computeroutput"><span class="identifier">text</span><span class="special">.</span><span class="identifier">get</span><span class="special">()</span></code> is

-        If you need to get the document root of some node, you can use the following
-        function:
-      </p>
-<pre class="programlisting"><span class="identifier">xml_node</span> <span class="identifier">xml_node</span><span class="special">::</span><span class="identifier">root</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>
-</pre>
-<p>
-        This function returns the node with type <a class="link" href="dom.html#node_document">node_document</a>,
-        which is the root node of the document the node belongs to (unless the node
-        is null, in which case null node is returned).
-      </p>
-<a name="xml_node::path"></a><a name="xml_node::first_element_by_path"></a><p>
-        While pugixml supports complex XPath expressions, sometimes a simple path
-        handling facility is needed. There are two functions, for getting node path
-        and for converting path to a node:
-      </p>
-<pre class="programlisting"><span class="identifier">string_t</span> <span class="identifier">xml_node</span><span class="special">::</span><span class="identifier">path</span><span class="special">(</span><span class="identifier">char_t</span> <span class="identifier">delimiter</span> <span class="special">=</span> <span class="char">'/'</span><span class="special">)</span> <span class="keyword">const</span><span class="special">;</span>
-<span class="identifier">xml_node</span> <span class="identifier">xml_node</span><span class="special">::</span><span class="identifier">first_element_by_path</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">char_t</span><span class="special">*</span> <span class="identifier">path</span><span class="special">,</span> <span class="identifier">char_t</span> <span class="identifier">delimiter</span> <span class="special">=</span> <span class="char">'/'</span><span class="special">)</span> <span class="keyword">const</span><span class="special">;</span>
-</pre>
-<p>
-        Node paths consist of node names, separated with a delimiter (which is <code class="computeroutput"><span class="special">/</span></code> by default); also paths can contain self
-        (<code class="computeroutput"><span class="special">.</span></code>) and parent (<code class="computeroutput"><span class="special">..</span></code>) pseudo-names, so that this is a valid
-        path: <code class="computeroutput"><span class="string">"../../foo/./bar"</span></code>.
-        <code class="computeroutput"><span class="identifier">path</span></code> returns the path to
-        the node from the document root, <code class="computeroutput"><span class="identifier">first_element_by_path</span></code>
-        looks for a node represented by a given path; a path can be an absolute one
-        (absolute paths start with the delimiter), in which case the rest of the
-        path is treated as document root relative, and relative to the given node.
-        For example, in the following document: <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">a</span><span class="special">&gt;&lt;</span><span class="identifier">b</span><span class="special">&gt;&lt;</span><span class="identifier">c</span><span class="special">/&gt;&lt;/</span><span class="identifier">b</span><span class="special">&gt;&lt;/</span><span class="identifier">a</span><span class="special">&gt;</span></code>,
-        node <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">c</span><span class="special">/&gt;</span></code> has path <code class="computeroutput"><span class="string">"a/b/c"</span></code>;
-        calling <code class="computeroutput"><span class="identifier">first_element_by_path</span></code>
-        for document with path <code class="computeroutput"><span class="string">"a/b"</span></code>
-        results in node <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">b</span><span class="special">/&gt;</span></code>; calling <code class="computeroutput"><span class="identifier">first_element_by_path</span></code>
-        for node <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">a</span><span class="special">/&gt;</span></code> with path <code class="computeroutput"><span class="string">"../a/./b/../."</span></code>
-        results in node <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">a</span><span class="special">/&gt;</span></code>; calling <code class="computeroutput"><span class="identifier">first_element_by_path</span></code>
-        with path <code class="computeroutput"><span class="string">"/a"</span></code> results
-        in node <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">a</span><span class="special">/&gt;</span></code> for any node.
-      </p>
-<p>
-        In case path component is ambiguous (if there are two nodes with given name),
-        the first one is selected; paths are not guaranteed to uniquely identify
-        nodes in a document. If any component of a path is not found, the result
-        of <code class="computeroutput"><span class="identifier">first_element_by_path</span></code>
-        is null node; also <code class="computeroutput"><span class="identifier">first_element_by_path</span></code>
-        returns null node for null nodes, in which case the path does not matter.
-        <code class="computeroutput"><span class="identifier">path</span></code> returns an empty string
-        for null nodes.

-<a name="xml_node::offset_debug"></a><p>
-        pugixml does not record row/column information for nodes upon parsing for
-        efficiency reasons. However, if the node has not changed in a significant
-        way since parsing (the name/value are not changed, and the node itself is
-        the original one, i.e. it was not deleted from the tree and re-added later),
-        it is possible to get the offset from the beginning of XML buffer:
-      </p>
-<pre class="programlisting"><span class="identifier">ptrdiff_t</span> <span class="identifier">xml_node</span><span class="special">::</span><span class="identifier">offset_debug</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>
-</pre>
-<p>
-        If the offset is not available (this happens if the node is null, was not
-        originally parsed from a stream, or has changed in a significant way), the
-        function returns -1. Otherwise it returns the offset to node's data from
-        the beginning of XML buffer in <a class="link" href="dom.html#char_t">pugi::char_t</a>
-        units. For more information on parsing offsets, see <a class="link" href="loading.html#xml_parse_result::offset">parsing

-      pugixml stores XML data in DOM-like way: the entire XML document (both document
-      structure and element data) is stored in memory as a tree. The tree can be
-      loaded from a character stream (file, string, C++ I/O stream), then traversed
-      with the special API or XPath expressions. The whole tree is mutable: both
-      node structure and node/attribute data can be changed at any time. Finally,
-      the result of document transformations can be saved to a character stream (file,
-      C++ I/O stream or custom transport).

-<p>
-        The XML document is represented with a tree data structure. The root of the
-        tree is the document itself, which corresponds to C++ type <a class="link" href="dom.html#xml_document">xml_document</a>.
-        Document has one or more child nodes, which correspond to C++ type <a class="link" href="dom.html#xml_node">xml_node</a>. Nodes have different types; depending
-        on a type, a node can have a collection of child nodes, a collection of attributes,
-        which correspond to C++ type <a class="link" href="dom.html#xml_attribute">xml_attribute</a>,
-        and some additional data (i.e. name).
-      </p>
-<a name="xml_node_type"></a><p>
-        The tree nodes can be of one of the following types (which together form
-        the enumeration <code class="computeroutput"><span class="identifier">xml_node_type</span></code>):

-            node corresponds to <a class="link" href="dom.html#xml_document">xml_document</a>

-        Despite the fact that there are several node types, there are only three

-        <code class="computeroutput"><span class="identifier">xml_node</span></code>, <code class="computeroutput"><span class="identifier">xml_attribute</span></code>);
-        some operations on <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        are only valid for certain node types. The classes are described below.

-        <code class="computeroutput"><span class="identifier">xml_document</span></code> is the owner
-        of the entire document structure; it is a non-copyable class. The interface

-        of loading functions (see <a class="xref" href="loading.html" title="Loading document"> Loading document</a>), saving functions (see <a class="xref" href="saving.html" title="Saving document"> Saving document</a>)
-        and the entire interface of <code class="computeroutput"><span class="identifier">xml_node</span></code>,
-        which allows for document inspection and/or modification. Note that while
-        <code class="computeroutput"><span class="identifier">xml_document</span></code> is a sub-class
-        of <code class="computeroutput"><span class="identifier">xml_node</span></code>, <code class="computeroutput"><span class="identifier">xml_node</span></code> is not a polymorphic type; the
-        inheritance is present only to simplify usage. Alternatively you can use
-        the <code class="computeroutput"><span class="identifier">document_element</span></code> function

-        You can then populate it with data using either tree modification functions
-        or loading functions; all loading functions destroy the previous tree with
-        all occupied memory, which puts existing node/attribute handles for this
-        document to invalid state. If you want to destroy the previous tree, you

-        function; it destroys the tree and replaces it with either an empty one or
-        a copy of the specified document. Destructor of <code class="computeroutput"><span class="identifier">xml_document</span></code>
-        also destroys the tree, thus the lifetime of the document object should exceed

-        <code class="computeroutput"><span class="identifier">xml_node</span></code> is the handle to
-        document node; it can point to any node in the document, including the document
-        node itself. There is a common interface for nodes of all types; the actual
-        <a class="link" href="dom.html#xml_node_type">node type</a> can be queried via the <code class="computeroutput"><span class="identifier">xml_node</span><span class="special">::</span><span class="identifier">type</span><span class="special">()</span></code>
-        method. Note that <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        is only a handle to the actual node, not the node itself - you can have several
-        <code class="computeroutput"><span class="identifier">xml_node</span></code> handles pointing
-        to the same underlying object. Destroying <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        handle does not destroy the node and does not remove it from the tree. The
-        size of <code class="computeroutput"><span class="identifier">xml_node</span></code> is equal
-        to that of a pointer, so it is nothing more than a lightweight wrapper around
-        a pointer; you can safely pass or return <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        objects by value without additional overhead.
-      </p>
-<a name="node_null"></a><p>
-        There is a special value of <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        type, known as null node or empty node (such nodes have type <code class="computeroutput"><span class="identifier">node_null</span></code>). It does not correspond to any
-        node in any document, and thus resembles null pointer. However, all operations
-        are defined on empty nodes; generally the operations don't do anything and
-        return empty nodes/attributes or empty strings as their result (see documentation
-        for specific functions for more detailed information). This is useful for
-        chaining calls; i.e. you can get the grandparent of a node like so: <code class="computeroutput"><span class="identifier">node</span><span class="special">.</span><span class="identifier">parent</span><span class="special">().</span><span class="identifier">parent</span><span class="special">()</span></code>; if a node is a null node or it does not
-        have a parent, the first <code class="computeroutput"><span class="identifier">parent</span><span class="special">()</span></code> call returns null node; the second <code class="computeroutput"><span class="identifier">parent</span><span class="special">()</span></code>
-        call then also returns null node, which makes error handling easier.
-      </p>
-<a name="xml_attribute"></a><p>
-        <code class="computeroutput"><span class="identifier">xml_attribute</span></code> is the handle
-        to an XML attribute; it has the same semantics as <code class="computeroutput"><span class="identifier">xml_node</span></code>,
-        i.e. there can be several <code class="computeroutput"><span class="identifier">xml_attribute</span></code>
-        handles pointing to the same underlying object and there is a special null
-        attribute value, which propagates to function results.
-      </p>
-<a name="xml_attribute::ctor"></a><a name="xml_node::ctor"></a><p>
-        Both <code class="computeroutput"><span class="identifier">xml_node</span></code> and <code class="computeroutput"><span class="identifier">xml_attribute</span></code> have the default constructor
-        which initializes them to null objects.
-      </p>
-<a name="xml_attribute::comparison"></a><a name="xml_node::comparison"></a><p>
-        <code class="computeroutput"><span class="identifier">xml_node</span></code> and <code class="computeroutput"><span class="identifier">xml_attribute</span></code> try to behave like pointers,
-        that is, they can be compared with other objects of the same type, making
-        it possible to use them as keys in associative containers. All handles to
-        the same underlying object are equal, and any two handles to different underlying
-        objects are not equal. Null handles only compare as equal to themselves.
-        The result of relational comparison can not be reliably determined from the
-        order of nodes in file or in any other way. Do not use relational comparison
-        operators except for search optimization (i.e. associative container keys).
-      </p>

-        or <code class="computeroutput"><span class="identifier">xml_attribute</span></code> objects
-        as keys in hash-based associative containers, you can use the <code class="computeroutput"><span class="identifier">hash_value</span></code> member functions. They return
-        the hash values that are guaranteed to be the same for all handles to the
-        same underlying object. The hash value for null handles is 0.

-<a name="xml_attribute::unspecified_bool_type"></a><a name="xml_node::unspecified_bool_type"></a><a name="xml_attribute::empty"></a><a name="xml_node::empty"></a><p>
-        Finally handles can be implicitly cast to boolean-like objects, so that you
-        can test if the node/attribute is empty with the following code: <code class="computeroutput"><span class="keyword">if</span> <span class="special">(</span><span class="identifier">node</span><span class="special">)</span> <span class="special">{</span> <span class="special">...</span>
-        <span class="special">}</span></code> or <code class="computeroutput"><span class="keyword">if</span>
-        <span class="special">(!</span><span class="identifier">node</span><span class="special">)</span> <span class="special">{</span> <span class="special">...</span>
-        <span class="special">}</span> <span class="keyword">else</span> <span class="special">{</span> <span class="special">...</span> <span class="special">}</span></code>.
-        Alternatively you can check if a given <code class="computeroutput"><span class="identifier">xml_node</span></code>/<code class="computeroutput"><span class="identifier">xml_attribute</span></code> handle is null by calling
-        the following methods:
-      </p>
-<pre class="programlisting"><span class="keyword">bool</span> <span class="identifier">xml_attribute</span><span class="special">::</span><span class="identifier">empty</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>

-        Nodes and attributes do not exist without a document tree, so you can't create
-        them without adding them to some document. Once underlying node/attribute
-        objects are destroyed, the handles to those objects become invalid. While
-        this means that destruction of the entire tree invalidates all node/attribute
-        handles, it also means that destroying a subtree (by calling <a class="link" href="modify.html#xml_node::remove_child">xml_node::remove_child</a>)
-        or removing an attribute invalidates the corresponding handles. There is
-        no way to check handle validity; you have to ensure correctness through external
-        mechanisms.

-        that is defined as the character type and depends on the library configuration;
-        it will be also used in the documentation hereafter. There is also a type
-        <code class="computeroutput"><span class="identifier">pugi</span><span class="special">::</span><span class="identifier">string_t</span></code>, which is defined as the STL string
-        of the character type; it corresponds to <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>
-        in char mode and to <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">wstring</span></code> in wchar_t mode.
-      </p>
-<p>
-        In addition to the interface, the internal implementation changes to store
-        XML data as <code class="computeroutput"><span class="identifier">pugi</span><span class="special">::</span><span class="identifier">char_t</span></code>; this means that these two modes
-        have different memory usage characteristics. The conversion to <code class="computeroutput"><span class="identifier">pugi</span><span class="special">::</span><span class="identifier">char_t</span></code> upon document loading and from
-        <code class="computeroutput"><span class="identifier">pugi</span><span class="special">::</span><span class="identifier">char_t</span></code> upon document saving happen automatically,
-        which also carries minor performance penalty. The general advice however
-        is to select the character mode based on usage scenario, i.e. if UTF-8 is
-        inconvenient to process and most of your XML data is non-ASCII, wchar_t mode
-        is probably a better choice.

-        Both functions accept a null-terminated string as an argument <code class="computeroutput"><span class="identifier">str</span></code>, and return the converted string.
-        <code class="computeroutput"><span class="identifier">as_utf8</span></code> performs conversion
-        from UTF-16/32 to UTF-8; <code class="computeroutput"><span class="identifier">as_wide</span></code>
-        performs conversion from UTF-8 to UTF-16/32. Invalid UTF sequences are silently
-        discarded upon conversion. <code class="computeroutput"><span class="identifier">str</span></code>
-        has to be a valid string; passing null pointer results in undefined behavior.

-        </p>
-<p>
-          When the document is loaded from file/buffer, unless an inplace loading
-          function is used (see <a class="xref" href="loading.html#manual.loading.memory" title="Loading document from memory"> Loading document from memory</a>), a complete copy of character
-          stream is made; all names/values of nodes and attributes are allocated
-          in this buffer. This buffer is allocated via a single large allocation
-          and is only freed when document memory is reclaimed (i.e. if the <a class="link" href="dom.html#xml_document">xml_document</a> object is destroyed or if another
-          document is loaded in the same object). Also when loading from file or
-          stream, an additional large allocation may be performed if encoding conversion
-          is required; a temporary buffer is allocated, and it is freed before load
-          function returns.

-          All additional memory, such as memory for document structure (node/attribute
-          objects) and memory for node/attribute names/values is allocated in pages
-          on the order of 32 kilobytes; actual objects are allocated inside the pages
-          using a memory management scheme optimized for fast allocation/deallocation
-          of many small objects. Because of the scheme specifics, the pages are only
-          destroyed if all objects inside them are destroyed; also, generally destroying
-          an object does not mean that subsequent object creation will reuse the
-          same memory. This means that it is possible to devise a usage scheme which
-          will lead to higher memory usage than expected; one example is adding a
-          lot of nodes, and them removing all even numbered ones; not a single page
-          is reclaimed in the process. However this is an example specifically crafted
-          to produce unsatisfying behavior; in all practical usage scenarios the
-          memory consumption is less than that of a general-purpose allocator because
-          allocation meta-data is very small in size.

-<p>
-          You can download the latest source distribution via one of the following
-          links:
-        </p>
-<pre class="programlisting"><a href="https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.zip" target="_top">https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.zip</a>

-</pre>
-<p>
-          The distribution contains library source, documentation (the manual you're
-          reading now and the quick start guide) and some code examples. After downloading
-          the distribution, install pugixml by extracting all files from the compressed
-          archive. The files have different line endings depending on the archive
-          format - <code class="filename">.zip</code> archive has Windows line endings, <code class="filename">.tar.gz</code> archive has Unix
-          line endings. Otherwise the files in both archives are identical.
-        </p>

-          The Git repository is located at <a href="https://github.com/zeux/pugixml/" target="_top">https://github.com/zeux/pugixml/</a>.
-          There is a Git tag "v{version}" for each version; also there
-          is the "latest" tag, which always points to the latest stable
-          release.
-        </p>
-<p>
-          For example, to checkout the current version, you can use this command:
-        </p>
-<pre class="programlisting">git clone https://github.com/zeux/pugixml
-cd pugixml
-git checkout v1.6
-</pre>
-<p>
-          The repository contains library source, documentation, code examples and
-          full unit test suite.
-        </p>
-<p>
-          Use latest version tag if you want to automatically get new versions. Use
-          other tags if you want to switch to new versions only explicitly. Also
-          please note that the master branch contains the work-in-progress version
-          of the code; while this means that you can get new features and bug fixes
-          from master without waiting for a new release, this also means that occasionally
-          the code can be broken in some configurations.

-        pugixml is distributed in source form without any pre-built binaries; you
-        have to build them yourself.
-      </p>
-<p>
-        The complete pugixml source consists of three files - one source file, <code class="filename">pugixml.cpp</code>,
-        and two header files, <code class="filename">pugixml.hpp</code> and <code class="filename">pugiconfig.hpp</code>. <code class="filename">pugixml.hpp</code> is the primary
-        header which you need to include in order to use pugixml classes/functions;
-        <code class="filename">pugiconfig.hpp</code> is a supplementary configuration file (see <a class="xref" href="install.html#manual.install.building.config" title="Additional configuration options"> Additional configuration
-        options</a>).
-        The rest of this guide assumes that <code class="filename">pugixml.hpp</code> is either in the current directory
-        or in one of include directories of your projects, so that <code class="computeroutput"><span class="preprocessor">#include</span> <span class="string">"pugixml.hpp"</span></code>
-        can find the header; however you can also use relative path (i.e. <code class="computeroutput"><span class="preprocessor">#include</span> <span class="string">"../libs/pugixml/src/pugixml.hpp"</span></code>)
-        or include directory-relative path (i.e. <code class="computeroutput"><span class="preprocessor">#include</span>
-        <span class="special">&lt;</span><span class="identifier">xml</span><span class="special">/</span><span class="identifier">thirdparty</span><span class="special">/</span><span class="identifier">pugixml</span><span class="special">/</span><span class="identifier">src</span><span class="special">/</span><span class="identifier">pugixml</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">&gt;</span></code>).

-          The easiest way to build pugixml is to compile the source file, <code class="filename">pugixml.cpp</code>,
-          along with the existing library/executable. This process depends on the
-          method of building your application; for example, if you're using Microsoft
-          Visual Studio<a href="#ftn.trademarks" class="footnote" name="trademarks"><sup class="footnote">[1]</sup></a>, Apple Xcode, Code::Blocks or any other IDE, just add <code class="filename">pugixml.cpp</code> to
-          one of your projects.
-        </p>
-<p>
-          If you're using Microsoft Visual Studio and the project has precompiled
-          headers turned on, you'll see the following error messages:
-        </p>
-<pre class="programlisting">pugixml.cpp(3477) : fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "stdafx.h"' to your source?</pre>
-<p>
-          The correct way to resolve this is to disable precompiled headers for <code class="filename">pugixml.cpp</code>;
-          you have to set "Create/Use Precompiled Header" option (Properties
-          dialog -&gt; C/C++ -&gt; Precompiled Headers -&gt; Create/Use Precompiled
-          Header) to "Not Using Precompiled Headers". You'll have to do
-          it for all project configurations/platforms (you can select Configuration
-          "All Configurations" and Platform "All Platforms" before
-          editing the option):

-<p>
-          It's possible to compile pugixml as a standalone static library. This process
-          depends on the method of building your application; pugixml distribution
-          comes with project files for several popular IDEs/build systems. There
-          are project files for Apple XCode3, Code::Blocks, Codelite, Microsoft Visual
-          Studio 2005, 2008, 2010, and configuration scripts for CMake and premake4.
-          You're welcome to submit project files/build scripts for other software;
-          see <a class="xref" href="../manual.html#manual.overview.feedback" title="Feedback"> Feedback</a>.
-        </p>
-<p>
-          There are two projects for each version of Microsoft Visual Studio: one
-          for dynamically linked CRT, which has a name like <code class="filename">pugixml_vs2008.vcproj</code>,
-          and another one for statically linked CRT, which has a name like <code class="filename">pugixml_vs2008_static.vcproj</code>.
-          You should select the version that matches the CRT used in your application;
-          the default option for new projects created by Microsoft Visual Studio
-          is dynamically linked CRT, so unless you changed the defaults, you should
-          use the version with dynamic CRT (i.e. <code class="filename">pugixml_vs2008.vcproj</code> for Microsoft
-          Visual Studio 2008).
-        </p>
-<p>
-          In addition to adding pugixml project to your workspace, you'll have to
-          make sure that your application links with pugixml library. If you're using
-          Microsoft Visual Studio 2005/2008, you can add a dependency from your application
-          project to pugixml one. If you're using Microsoft Visual Studio 2010, you'll
-          have to add a reference to your application project instead. For other
-          IDEs/systems, consult the relevant documentation.

-<p>
-          It's possible to compile pugixml as a standalone shared library. The process
-          is usually similar to the static library approach; however, no preconfigured
-          projects/scripts are included into pugixml distribution, so you'll have
-          to do it yourself. Generally, if you're using GCC-based toolchain, the
-          process does not differ from building any other library as DLL (adding
-          -shared to compilation flags should suffice); if you're using MSVC-based
-          toolchain, you'll have to explicitly mark exported symbols with a declspec
-          attribute. You can do it by defining <a class="link" href="install.html#PUGIXML_API">PUGIXML_API</a>
-          macro, i.e. via <code class="filename">pugiconfig.hpp</code>:

-            If you're using STL-related functions, you should use the shared runtime

-            DLL' or 'Multithreaded Debug DLL' to 'Runtime library' property (/MD
-            or /MDd linker switch). You should also make sure that your runtime library

-        mode</a>
-</h4></div></div></div>
-<p>
-          It's possible to use pugixml in header-only mode. This means that all source
-          code for pugixml will be included in every translation unit that includes
-          <code class="filename">pugixml.hpp</code>. This is how most of Boost and STL libraries work.
-        </p>
-<p>
-          Note that there are advantages and drawbacks of this approach. Header mode
-          may improve tree traversal/modification performance (because many simple
-          functions will be inlined), if your compiler toolchain does not support
-          link-time optimization, or if you have it turned off (with link-time optimization
-          the performance should be similar to non-header mode). However, since compiler
-          now has to compile pugixml source once for each translation unit that includes
-          it, compilation times may increase noticeably. If you want to use pugixml
-          in header mode but do not need XPath support, you can consider disabling
-          it by using <a class="link" href="install.html#PUGIXML_NO_XPATH">PUGIXML_NO_XPATH</a> define
-          to improve compilation time.
-        </p>
-<p>
-          Enabling header-only mode is a two-step process:
-        </p>
-<div class="orderedlist"><ol class="orderedlist" type="1">
-<li class="listitem">
-              You have to define <code class="computeroutput"><span class="identifier">PUGIXML_HEADER_ONLY</span></code>
-            </li>
-<li class="listitem">
-              You have to include <code class="filename">pugixml.cpp</code> whenever you include pugixml.hpp
-            </li>
-</ol></div>
-<p>
-          Both of these are best done via <code class="filename">pugiconfig.hpp</code> like this:
-        </p>
-<pre class="programlisting"><span class="preprocessor">#define</span> <span class="identifier">PUGIXML_HEADER_ONLY</span>
-<span class="preprocessor">#include</span> <span class="string">"pugixml.cpp"</span>
-</pre>
-<p>
-          Note that it is safe to compile <code class="filename">pugixml.cpp</code> if <code class="computeroutput"><span class="identifier">PUGIXML_HEADER_ONLY</span></code>
-          is defined - so if you want to i.e. use header-only mode only in Release
-          configuration, you can include pugixml.cpp in your project (see <a class="xref" href="install.html#manual.install.building.embed" title="Building pugixml as a part of another static library/executable"> Building pugixml as
-        a part of another static library/executable</a>),

-          pugixml uses several defines to control the compilation process. There
-          are two ways to define them: either put the needed definitions to <code class="filename">pugiconfig.hpp</code> (it
-          has some examples that are commented out) or provide them via compiler
-          command-line. Consistency is important: the definitions should match in
-          all source files that include <code class="filename">pugixml.hpp</code> (including pugixml sources) throughout
-          the application. Adding defines to <code class="filename">pugiconfig.hpp</code> lets you guarantee this,
-          unless your macro definition is wrapped in preprocessor <code class="computeroutput"><span class="preprocessor">#if</span></code>/<code class="computeroutput"><span class="preprocessor">#ifdef</span></code> directive and this directive
-          is not consistent. <code class="filename">pugiconfig.hpp</code> will never contain anything but comments,
-          which means that when upgrading to a new version, you can safely leave
-          your modified version intact.

-          as character type) and UTF-16/32 style interface (the in-memory text encoding

-      pugixml provides several functions for loading XML data from various places
-      - files, C++ iostreams, memory buffers. All functions use an extremely fast
-      non-validating parser. This parser is not fully W3C conformant - it can load
-      any valid XML document, but does not perform some well-formedness checks. While
-      considerable effort is made to reject invalid XML documents, some validation
-      is not performed for performance reasons. Also some XML transformations (i.e.
-      EOL handling or attribute value normalization) can impact parsing speed and
-      thus can be disabled. However for vast majority of XML documents there is no
-      performance difference between different parsing options. Parsing options also
-      control whether certain XML nodes are parsed; see <a class="xref" href="loading.html#manual.loading.options" title="Parsing options"> Parsing options</a> for
-      more information.
-    </p>
-<p>
-      XML data is always converted to internal character format (see <a class="xref" href="dom.html#manual.dom.unicode" title="Unicode interface"> Unicode interface</a>)
-      before parsing. pugixml supports all popular Unicode encodings (UTF-8, UTF-16
-      (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally
-      supported since it's a strict subset of UTF-16) and handles all encoding conversions
-      automatically. Unless explicit encoding is specified, loading functions perform
-      automatic encoding detection based on first few characters of XML data, so
-      in almost all cases you do not have to specify document encoding. Encoding
-      conversion is described in more detail in <a class="xref" href="loading.html#manual.loading.encoding" title="Encodings"> Encodings</a>.

-        These functions accept the file path as its first argument, and also two
-        optional arguments, which specify parsing options (see <a class="xref" href="loading.html#manual.loading.options" title="Parsing options"> Parsing options</a>)
-        and input data encoding (see <a class="xref" href="loading.html#manual.loading.encoding" title="Encodings"> Encodings</a>). The path has the target
-        operating system format, so it can be a relative or absolute one, it should
-        have the delimiters of the target system, it should have the exact case if
-        the target file system is case-sensitive, etc.
-      </p>
-<p>
-        File path is passed to the system file opening function as is in case of
-        the first function (which accepts <code class="computeroutput"><span class="keyword">const</span>
-        <span class="keyword">char</span><span class="special">*</span> <span class="identifier">path</span></code>); the second function either uses
-        a special file opening function if it is provided by the runtime library
-        or converts the path to UTF-8 and uses the system file opening function.
-      </p>
-<p>
-        <code class="computeroutput"><span class="identifier">load_file</span></code> destroys the existing
-        document tree and then tries to load the new tree from the specified file.
-        The result of the operation is returned in an <a class="link" href="loading.html#xml_parse_result">xml_parse_result</a>
-        object; this object contains the operation status and the related information

-        Sometimes XML data should be loaded from some other source than a file, i.e.
-        HTTP URL; also you may want to load XML data from file using non-standard
-        functions, i.e. to use your virtual file system facilities or to load XML
-        from gzip-compressed files. All these scenarios require loading document

-        All functions accept the buffer which is represented by a pointer to XML
-        data, <code class="computeroutput"><span class="identifier">contents</span></code>, and data
-        size in bytes. Also there are two optional arguments, which specify parsing
-        options (see <a class="xref" href="loading.html#manual.loading.options" title="Parsing options"> Parsing options</a>) and input data encoding (see <a class="xref" href="loading.html#manual.loading.encoding" title="Encodings"> Encodings</a>).
-        The buffer does not have to be zero-terminated.
-      </p>
-<p>
-        <code class="computeroutput"><span class="identifier">load_buffer</span></code> function works
-        with immutable buffer - it does not ever modify the buffer. Because of this
-        restriction it has to create a private buffer and copy XML data to it before
-        parsing (applying encoding conversions if necessary). This copy operation
-        carries a performance penalty, so inplace functions are provided - <code class="computeroutput"><span class="identifier">load_buffer_inplace</span></code> and <code class="computeroutput"><span class="identifier">load_buffer_inplace_own</span></code>
-        store the document data in the buffer, modifying it in the process. In order
-        for the document to stay valid, you have to make sure that the buffer's lifetime
-        exceeds that of the tree if you're using inplace functions. In addition to
-        that, <code class="computeroutput"><span class="identifier">load_buffer_inplace</span></code>
-        does not assume ownership of the buffer, so you'll have to destroy it yourself;
-        <code class="computeroutput"><span class="identifier">load_buffer_inplace_own</span></code> assumes
-        ownership of the buffer and destroys it once it is not needed. This means
-        that if you're using <code class="computeroutput"><span class="identifier">load_buffer_inplace_own</span></code>,
-        you have to allocate memory with pugixml allocation function (you can get
-        it via <a class="link" href="dom.html#get_memory_allocation_function">get_memory_allocation_function</a>).
-      </p>
-<p>
-        The best way from the performance/memory point of view is to load document
-        using <code class="computeroutput"><span class="identifier">load_buffer_inplace_own</span></code>;
-        this function has maximum control of the buffer with XML data so it is able
-        to avoid redundant copies and reduce peak memory usage while parsing. This
-        is the recommended function if you have to load the document from memory
-        and performance is critical.
-      </p>
-<a name="xml_document::load_string"></a><p>
-        There is also a simple helper function for cases when you want to load the
-        XML document from null-terminated character string:

-</pre>
-<p>
-        It is equivalent to calling <code class="computeroutput"><span class="identifier">load_buffer</span></code>
-        with <code class="computeroutput"><span class="identifier">size</span></code> being either <code class="computeroutput"><span class="identifier">strlen</span><span class="special">(</span><span class="identifier">contents</span><span class="special">)</span></code>
-        or <code class="computeroutput"><span class="identifier">wcslen</span><span class="special">(</span><span class="identifier">contents</span><span class="special">)</span> <span class="special">*</span> <span class="keyword">sizeof</span><span class="special">(</span><span class="keyword">wchar_t</span><span class="special">)</span></code>,
-        depending on the character type. This function assumes native encoding for
-        input data, so it does not do any encoding conversion. In general, this function
-        is fine for loading small documents from string literals, but has more overhead
-        and less functionality than the buffer loading functions.

-        (i.e. file stream) or any third-party compliant implementation (i.e. Boost

-        member function can be used to convert parsing status to a string; the returned

-        you need a localized string. However please note that the exact messages
-        returned by <code class="computeroutput"><span class="identifier">description</span><span class="special">()</span></code>

-        the last element may have an unexpected name/value; for example, if the attribute
-        value does not end with the necessary quotation mark, like in <code class="literal">&lt;node
-        attr="value&gt;some data&lt;/node&gt;</code> example, the value of

-        pugixml does not track the current line during parsing; this offset is in
-        units of <a class="link" href="dom.html#char_t">pugi::char_t</a> (bytes for character
-        mode, wide characters for wide character mode). Many text editors support
-        'Go To Position' feature - you can use it to locate the exact error position.
-        Alternatively, if you're loading the document from memory, you can display
-        the error chunk along with the error description (see the example code below).

-        All document loading functions accept the optional parameter <code class="computeroutput"><span class="identifier">options</span></code>. This is a bitmask that customizes
-        the parsing process: you can select the node types that are parsed and various
-        transformations that are performed with the XML text. Disabling certain transformations
-        can improve parsing performance for some documents; however, the code for
-        all transformations is very well optimized, and thus the majority of documents
-        won't get any performance benefit. As a rule of thumb, only modify parsing
-        flags if you want to get some nodes in the document that are excluded by
-        default (i.e. declaration or comment nodes).

-        pugixml is not fully W3C conformant - it can load any valid XML document,
-        but does not perform some well-formedness checks. While considerable effort
-        is made to reject invalid XML documents, some validation is not performed
-        because of performance reasons.
-      </p>
-<p>
-        There is only one non-conformant behavior when dealing with valid XML documents:
-        pugixml does not use information supplied in document type declaration for
-        parsing. This means that entities declared in DOCTYPE are not expanded, and
-        all attribute/PCDATA values are always processed in a uniform way that depends
-        only on parsing options.

-      The document in pugixml is fully mutable: you can completely change the document
-      structure and modify the data of nodes/attributes. This section provides documentation
-      for the relevant functions. All functions take care of memory management and
-      structural integrity themselves, so they always result in structurally valid
-      tree - however, it is possible to create an invalid XML tree (for example,
-      by adding two attributes with the same name or by setting attribute/node name
-      to empty/invalid string). Tree modification is optimized for performance and
-      for memory consumption, so if you have enough memory you can create documents
-      from scratch with pugixml and later save them to file/stream instead of relying
-      on error-prone manual text writing and without too much overhead.
-    </p>
-<p>
-      All member functions that change node/attribute data or structure are non-constant
-      and thus can not be called on constant handles. However, you can easily convert
-      constant handle to non-constant one by simple assignment: <code class="computeroutput"><span class="keyword">void</span>
-      <span class="identifier">foo</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">pugi</span><span class="special">::</span><span class="identifier">xml_node</span><span class="special">&amp;</span> <span class="identifier">n</span><span class="special">)</span>
-      <span class="special">{</span> <span class="identifier">pugi</span><span class="special">::</span><span class="identifier">xml_node</span> <span class="identifier">nc</span> <span class="special">=</span> <span class="identifier">n</span><span class="special">;</span> <span class="special">}</span></code>, so const-correctness
-      here mainly provides additional documentation.

-        As discussed before, nodes can have name and value, both of which are strings.
-        Depending on node type, name or value may be absent. <a class="link" href="dom.html#node_document">node_document</a>
-        nodes do not have a name or value, <a class="link" href="dom.html#node_element">node_element</a>
-        and <a class="link" href="dom.html#node_declaration">node_declaration</a> nodes always
-        have a name but never have a value, <a class="link" href="dom.html#node_pcdata">node_pcdata</a>,
-        <a class="link" href="dom.html#node_cdata">node_cdata</a>, <a class="link" href="dom.html#node_comment">node_comment</a>
-        and <a class="link" href="dom.html#node_doctype">node_doctype</a> nodes never have a name
-        but always have a value (it may be empty though), <a class="link" href="dom.html#node_pi">node_pi</a>
-        nodes always have a name and a value (again, value may be empty). In order
-        to set node's name or value, you can use the following functions:
-      </p>
-<pre class="programlisting"><span class="keyword">bool</span> <span class="identifier">xml_node</span><span class="special">::</span><span class="identifier">set_name</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">char_t</span><span class="special">*</span> <span class="identifier">rhs</span><span class="special">);</span>

-</pre>
-<p>
-        Both functions try to set the name/value to the specified string, and return
-        the operation result. The operation fails if the node can not have name or
-        value (for instance, when trying to call <code class="computeroutput"><span class="identifier">set_name</span></code>
-        on a <a class="link" href="dom.html#node_pcdata">node_pcdata</a> node), if the node handle
-        is null, or if there is insufficient memory to handle the request. The provided
-        string is copied into document managed memory and can be destroyed after
-        the function returns (for example, you can safely pass stack-allocated buffers
-        to these functions). The name/value content is not verified, so take care
-        to use only valid XML names, or the document may become malformed.

-        If you do not want your document to contain some node or attribute, you can
-        remove it with one of the following functions:
-      </p>
-<pre class="programlisting"><span class="keyword">bool</span> <span class="identifier">xml_node</span><span class="special">::</span><span class="identifier">remove_attribute</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">xml_attribute</span><span class="special">&amp;</span> <span class="identifier">a</span><span class="special">);</span>

-</pre>
-<p>
-        <code class="computeroutput"><span class="identifier">remove_attribute</span></code> removes
-        the attribute from the attribute list of the node, and returns the operation
-        result. <code class="computeroutput"><span class="identifier">remove_child</span></code> removes
-        the child node with the entire subtree (including all descendant nodes and
-        attributes) from the document, and returns the operation result. Removing
-        fails if one of the following is true:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
-<li class="listitem">
-            The node the function is called on is null;

-            list.
-          </li>
-</ul></div>
-<p>
-        Removing the attribute or node invalidates all handles to the same underlying
-        object, and also invalidates all iterators pointing to the same object. Removing
-        node also invalidates all past-the-end iterators to its attribute or child
-        node list. Be careful to ensure that all such handles and iterators either
-        do not exist or are not used after the attribute/node is removed.
-      </p>
-<p>
-        If you want to remove the attribute or child node by its name, two additional
-        helper functions are available:

-</pre>
-<p>
-        These functions look for the first attribute or child with the specified
-        name, and then remove it, returning the result. If there is no attribute
-        or child with such name, the function returns <code class="computeroutput"><span class="keyword">false</span></code>;
-        if there are two nodes with the given name, only the first node is deleted.
-        If you want to delete all nodes with the specified name, you can use code
-        like this: <code class="computeroutput"><span class="keyword">while</span> <span class="special">(</span><span class="identifier">node</span><span class="special">.</span><span class="identifier">remove_child</span><span class="special">(</span><span class="string">"tool"</span><span class="special">))</span> <span class="special">;</span></code>.

-        This function tries to set the contents to the specified string, and returns
-        the operation result. The operation fails if the text object was retrieved
-        from a node that can not have a value and is not an element node (i.e. it
-        is a <a class="link" href="dom.html#node_declaration">node_declaration</a> node), if the
-        text object is empty, or if there is insufficient memory to handle the request.
-        The provided string is copied into document managed memory and can be destroyed
-        after the function returns (for example, you can safely pass stack-allocated
-        buffers to this function). Note that if the text object was retrieved from
-        an element node, this function creates the PCDATA child node if necessary
-        (i.e. if the element node does not have a PCDATA/CDATA child already).

-        With the help of previously described functions, it is possible to create
-        trees with any contents and structure, including cloning the existing data.
-        However since this is an often needed operation, pugixml provides built-in
-        node/attribute cloning facilities. Since nodes and attributes do not exist
-        without a document tree, you can't create a standalone copy - you have to
-        immediately insert it somewhere in the tree. For this, you can use one of

-        The first method is more convenient, but slower than the other two. The relative
-        performance of <code class="computeroutput"><span class="identifier">append_copy</span></code>
-        and <code class="computeroutput"><span class="identifier">append_buffer</span></code> depends
-        on the buffer format - usually <code class="computeroutput"><span class="identifier">append_buffer</span></code>
-        is faster if the buffer is in native encoding (UTF-8 or wchar_t, depending
-        on <code class="computeroutput"><span class="identifier">PUGIXML_WCHAR_MODE</span></code>). At
-        the same time it might be less efficient in terms of memory usage - the implementation
-        makes a copy of the provided buffer, and the copy has the same lifetime as
-        the document - the memory used by that copy will be reclaimed after the document
-        is destroyed, but no sooner. Even deleting all nodes in the document, including
-        the appended ones, won't reclaim the memory.
-      </p>
-<p>
-        <code class="computeroutput"><span class="identifier">append_buffer</span></code> behaves in
-        the same way as <a class="link" href="loading.html#xml_document::load_buffer">xml_document::load_buffer</a>
-        - the input buffer is a byte buffer, with size in bytes; the buffer is not
-        modified and can be freed after the function returns.
-      </p>
-<a name="status_append_invalid_root"></a><p>
-        Since <code class="computeroutput"><span class="identifier">append_buffer</span></code> needs
-        to append child nodes to the current node, it only works if the current node
-        is either document or element node. Calling <code class="computeroutput"><span class="identifier">append_buffer</span></code>
-        on a node with any other type results in an error with <code class="computeroutput"><span class="identifier">status_append_invalid_root</span></code>
-        status.

-<p>
-      Often after creating a new document or loading the existing one and processing
-      it, it is necessary to save the result back to file. Also it is occasionally
-      useful to output the whole document or a subtree to some stream; use cases
-      include debug printing, serialization via network or other text-oriented medium,
-      etc. pugixml provides several functions to output any subtree of the document
-      to a file, stream or another generic transport interface; these functions allow
-      to customize the output format (see <a class="xref" href="saving.html#manual.saving.options" title="Output options"> Output options</a>), and also perform
-      necessary encoding conversions (see <a class="xref" href="saving.html#manual.saving.encoding" title="Encodings"> Encodings</a>). This section documents
-      the relevant functionality.
-    </p>
-<p>
-      Before writing to the destination the node/attribute data is properly formatted
-      according to the node type; all special XML symbols, such as &lt; and &amp;,
-      are properly escaped (unless <a class="link" href="saving.html#format_no_escapes">format_no_escapes</a>
-      flag is set). In order to guard against forgotten node/attribute names, empty
-      node/attribute names are printed as <code class="computeroutput"><span class="string">":anonymous"</span></code>.
-      For well-formed output, make sure all node and attribute names are set to meaningful
-      values.
-    </p>
-<p>
-      CDATA sections with values that contain <code class="computeroutput"><span class="string">"]]&gt;"</span></code>
-      are split into several sections as follows: section with value <code class="computeroutput"><span class="string">"pre]]&gt;post"</span></code> is written as <code class="computeroutput"><span class="special">&lt;![</span><span class="identifier">CDATA</span><span class="special">[</span><span class="identifier">pre</span><span class="special">]]]]&gt;&lt;![</span><span class="identifier">CDATA</span><span class="special">[&gt;</span><span class="identifier">post</span><span class="special">]]&gt;</span></code>.
-      While this alters the structure of the document (if you load the document after
-      saving it, there will be two CDATA sections instead of one), this is the only
-      way to escape CDATA contents.

-        These functions accept file path as its first argument, and also three optional
-        arguments, which specify indentation and other output options (see <a class="xref" href="saving.html#manual.saving.options" title="Output options"> Output options</a>)
-        and output data encoding (see <a class="xref" href="saving.html#manual.saving.encoding" title="Encodings"> Encodings</a>). The path has the target
-        operating system format, so it can be a relative or absolute one, it should
-        have the delimiters of the target system, it should have the exact case if
-        the target file system is case-sensitive, etc.
-      </p>
-<p>
-        File path is passed to the system file opening function as is in case of
-        the first function (which accepts <code class="computeroutput"><span class="keyword">const</span>
-        <span class="keyword">char</span><span class="special">*</span> <span class="identifier">path</span></code>); the second function either uses
-        a special file opening function if it is provided by the runtime library
-        or converts the path to UTF-8 and uses the system file opening function.
-      </p>
-<a name="xml_writer_file"></a><p>
-        <code class="computeroutput"><span class="identifier">save_file</span></code> opens the target
-        file for writing, outputs the requested header (by default a document declaration
-        is output, unless the document already has one), and then saves the document
-        contents. If the file could not be opened, the function returns <code class="computeroutput"><span class="keyword">false</span></code>. Calling <code class="computeroutput"><span class="identifier">save_file</span></code>
-        is equivalent to creating an <code class="computeroutput"><span class="identifier">xml_writer_file</span></code>

-        To enhance interoperability pugixml provides functions for saving document
-        to any object which implements C++ <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">ostream</span></code>
-        interface. This allows you to save documents to any standard C++ stream (i.e.
-        file stream) or any third-party compliant implementation (i.e. Boost Iostreams).
-        Most notably, this allows for easy debug output, since you can use <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">cout</span></code>
-        stream as saving target. There are two functions, one works with narrow character
-        streams, another handles wide character ones:

-        argument saves the document to the stream in the same way as <code class="computeroutput"><span class="identifier">save_file</span></code> (i.e. with requested header and
-        with encoding conversions). On the other hand, <code class="computeroutput"><span class="identifier">save</span></code>
-        with <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">wstream</span></code> argument saves the document to
-        the wide stream with <a class="link" href="loading.html#encoding_wchar">encoding_wchar</a>
-        encoding. Because of this, using <code class="computeroutput"><span class="identifier">save</span></code>
-        with wide character streams requires careful (usually platform-specific)
-        stream setup (i.e. using the <code class="computeroutput"><span class="identifier">imbue</span></code>
-        function). Generally use of wide streams is discouraged, however it provides
-        you with the ability to save documents to non-Unicode encodings, i.e. you
-        can save Shift-JIS encoded data if you set the correct locale.

-        In order to output the document via some custom transport, for example sockets,
-        you should create an object which implements <code class="computeroutput"><span class="identifier">xml_writer</span></code>
-        interface and pass it to <code class="computeroutput"><span class="identifier">save</span></code>
-        function. <code class="computeroutput"><span class="identifier">xml_writer</span><span class="special">::</span><span class="identifier">write</span></code> function is called with a buffer
-        as an input, where <code class="computeroutput"><span class="identifier">data</span></code> points
-        to buffer start, and <code class="computeroutput"><span class="identifier">size</span></code>
-        is equal to the buffer size in bytes. <code class="computeroutput"><span class="identifier">write</span></code>
-        implementation must write the buffer to the transport; it can not save the
-        passed buffer pointer, as the buffer contents will change after <code class="computeroutput"><span class="identifier">write</span></code> returns. The buffer contains the
-        chunk of document data in the desired encoding.
-      </p>
-<p>
-        <code class="computeroutput"><span class="identifier">write</span></code> function is called
-        with relatively large blocks (size is usually several kilobytes, except for
-        the last block that may be small), so there is often no need for additional
-        buffering in the implementation.
-      </p>
-<p>
-        This is a simple example of custom writer for saving document data to STL
-        string (<a href="../samples/save_custom_writer.cpp" target="_top">samples/save_custom_writer.cpp</a>);

-        These functions have the same arguments with the same meaning as the corresponding
-        <code class="computeroutput"><span class="identifier">xml_document</span><span class="special">::</span><span class="identifier">save</span></code> functions, and allow you to save the
-        subtree to either a C++ IOstream or to any object that implements <code class="computeroutput"><span class="identifier">xml_writer</span></code> interface.
-      </p>
-<p>
-        Saving a subtree differs from saving the whole document: the process behaves
-        as if <a class="link" href="saving.html#format_write_bom">format_write_bom</a> is off, and
-        <a class="link" href="saving.html#format_no_declaration">format_no_declaration</a> is on,
-        even if actual values of the flags are different. This means that BOM is
-        not written to the destination, and document declaration is only written
-        if it is the node itself or is one of node's children. Note that this also
-        holds if you're saving a document; this example (<a href="../samples/save_subtree.cpp" target="_top">samples/save_subtree.cpp</a>)
-        illustrates the difference:

-        pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little
-        endian), UTF-32 (big and little endian); UCS-2 is naturally supported since
-        it's a strict subset of UTF-16) and handles all encoding conversions during
-        output. The output encoding is set via the <code class="computeroutput"><span class="identifier">encoding</span></code>
-        parameter of saving functions, which is of type <code class="computeroutput"><span class="identifier">xml_encoding</span></code>.
-        The possible values for the encoding are documented in <a class="xref" href="loading.html#manual.loading.encoding" title="Encodings"> Encodings</a>;
-        the only flag that has a different meaning is <code class="computeroutput"><span class="identifier">encoding_auto</span></code>.
-      </p>
-<p>
-        While all other flags set the exact encoding, <code class="computeroutput"><span class="identifier">encoding_auto</span></code>
-        is meant for automatic encoding detection. The automatic detection does not
-        make sense for output encoding, since there is usually nothing to infer the
-        actual encoding from, so here <code class="computeroutput"><span class="identifier">encoding_auto</span></code>
-        means UTF-8 encoding, which is the most popular encoding for XML data storage.
-        This is also the default value of output encoding; specify another value
-        if you do not want UTF-8 encoded output.
-      </p>
-<p>
-        Also note that wide stream saving functions do not have <code class="computeroutput"><span class="identifier">encoding</span></code>
-        argument and always assume <a class="link" href="loading.html#encoding_wchar">encoding_wchar</a>
-        encoding.

-          The current behavior for Unicode conversion is to skip all invalid UTF
-          sequences during conversion. This behavior should not be relied upon; if
-          your node/attribute names do not contain any valid UTF sequences, they
-          may be output as if they are empty, which will result in malformed XML
-          document.

-        output, if <code class="computeroutput"><span class="identifier">format_no_declaration</span></code>
-        is not specified and if the document does not have a declaration node. However,
-        the default declaration is not customizable. If you want to customize the
-        declaration output, you need to create the declaration node yourself.

-          By default the declaration node is not added to the document during parsing.
-          If you just need to preserve the original declaration node, you have to
-          add the flag <a class="link" href="loading.html#parse_declaration">parse_declaration</a>
-          to the parsing flags; the resulting document will contain the original
-          declaration node, which will be output during saving.

-<p>
-        Declaration node is a node with type <a class="link" href="dom.html#node_declaration">node_declaration</a>;
-        it behaves like an element node in that it has attributes with values (but
-        it does not have child nodes). Therefore setting custom version, encoding
-        or standalone declaration involves adding attributes and setting attribute
-        values.
-      </p>
-<p>
-        This is an example that shows how to create a custom declaration node (<a href="../samples/save_declaration.cpp" target="_top">samples/save_declaration.cpp</a>):

-<p>
-      If the task at hand is to select a subset of document nodes that match some
-      criteria, it is possible to code a function using the existing traversal functionality
-      for any practical criteria. However, often either a data-driven approach is
-      desirable, in case the criteria are not predefined and come from a file, or
-      it is inconvenient to use traversal interfaces and a higher-level DSL is required.
-      There is a standard language for XML processing, XPath, that can be useful
-      for these cases. pugixml implements an almost complete subset of XPath 1.0.
-      Because of differences in document object model and some performance implications,
-      there are minor violations of the official specifications, which can be found
-      in <a class="xref" href="xpath.html#manual.xpath.w3c" title="Conformance to W3C specification"> Conformance to W3C specification</a>. The rest of this section describes the interface for XPath
-      functionality. Please note that if you wish to learn to use XPath language,
-      you have to look for other tutorials or manuals; for example, you can read
-      <a href="http://www.w3schools.com/xpath/" target="_top">W3Schools XPath tutorial</a>,

-        Each XPath expression can have one of the following types: boolean, number,
-        string or node set. Boolean type corresponds to <code class="computeroutput"><span class="keyword">bool</span></code>
-        type, number type corresponds to <code class="computeroutput"><span class="keyword">double</span></code>
-        type, string type corresponds to either <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>
-        or <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">wstring</span></code>, depending on whether <a class="link" href="dom.html#manual.dom.unicode" title="Unicode interface">wide
-        character interface is enabled</a>, and node set corresponds to <a class="link" href="xpath.html#xpath_node_set">xpath_node_set</a> type. There is an enumeration,
-        <code class="computeroutput"><span class="identifier">xpath_value_type</span></code>, which can
-        take the values <code class="computeroutput"><span class="identifier">xpath_type_boolean</span></code>,
-        <code class="computeroutput"><span class="identifier">xpath_type_number</span></code>, <code class="computeroutput"><span class="identifier">xpath_type_string</span></code> or <code class="computeroutput"><span class="identifier">xpath_type_node_set</span></code>,

-        Because an XPath node can be either a node or an attribute, there is a special
-        type, <code class="computeroutput"><span class="identifier">xpath_node</span></code>, which is
-        a discriminated union of these types. A value of this type contains two node
-        handles, one of <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        type, and another one of <code class="computeroutput"><span class="identifier">xml_attribute</span></code>
-        type; at most one of them can be non-null. The accessors to get these handles
-        are available:
-      </p>
-<pre class="programlisting"><span class="identifier">xml_node</span> <span class="identifier">xpath_node</span><span class="special">::</span><span class="identifier">node</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>
-<span class="identifier">xml_attribute</span> <span class="identifier">xpath_node</span><span class="special">::</span><span class="identifier">attribute</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>
-</pre>
-<p>
-        XPath nodes can be null, in which case both accessors return null handles.
-      </p>
-<p>
-        Note that as per XPath specification, each XPath node has a parent, which
-        can be retrieved via this function:
-      </p>
-<pre class="programlisting"><span class="identifier">xml_node</span> <span class="identifier">xpath_node</span><span class="special">::</span><span class="identifier">parent</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>
-</pre>
-<p>
-        <code class="computeroutput"><span class="identifier">parent</span></code> function returns the
-        node's parent if the XPath node corresponds to <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        handle (equivalent to <code class="computeroutput"><span class="identifier">node</span><span class="special">().</span><span class="identifier">parent</span><span class="special">()</span></code>), or the node to which the attribute belongs
-        to, if the XPath node corresponds to <code class="computeroutput"><span class="identifier">xml_attribute</span></code>
-        handle. For null nodes, <code class="computeroutput"><span class="identifier">parent</span></code>
-        returns null handle.
-      </p>
-<a name="xpath_node::unspecified_bool_type"></a><a name="xpath_node::comparison"></a><p>
-        Like node and attribute handles, XPath node handles can be implicitly cast
-        to boolean-like object to check if it is a null node, and also can be compared
-        for equality with each other.
-      </p>
-<a name="xpath_node::ctor"></a><p>
-        You can also create XPath nodes with one of the three constructors: the default
-        constructor, the constructor that takes node argument, and the constructor
-        that takes attribute and node arguments (in which case the attribute must
-        belong to the attribute list of the node). The constructor from <code class="computeroutput"><span class="identifier">xml_node</span></code> is implicit, so you can usually
-        pass <code class="computeroutput"><span class="identifier">xml_node</span></code> to functions
-        that expect <code class="computeroutput"><span class="identifier">xpath_node</span></code>. Apart
-        from that you usually don't need to create your own XPath node objects, since
-        they are returned to you via selection functions.
-      </p>
-<a name="xpath_node_set"></a><p>
-        XPath expressions operate not on single nodes, but instead on node sets.
-        A node set is a collection of nodes, which can be optionally ordered in either
-        a forward document order or a reverse one. Document order is defined in XPath
-        specification; an XPath node is before another node in document order if
-        it appears before it in XML representation of the corresponding document.
-      </p>
-<a name="xpath_node_set::const_iterator"></a><a name="xpath_node_set::begin"></a><a name="xpath_node_set::end"></a><p>
-        Node sets are represented by <code class="computeroutput"><span class="identifier">xpath_node_set</span></code>
-        object, which has an interface that resembles one of sequential random-access
-        containers. It has an iterator type along with usual begin/past-the-end iterator
-        accessors:
-      </p>
-<pre class="programlisting"><span class="keyword">typedef</span> <span class="keyword">const</span> <span class="identifier">xpath_node</span><span class="special">*</span> <span class="identifier">xpath_node_set</span><span class="special">::</span><span class="identifier">const_iterator</span><span class="special">;</span>
-<span class="identifier">const_iterator</span> <span class="identifier">xpath_node_set</span><span class="special">::</span><span class="identifier">begin</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>

-</pre>
-<a name="xpath_node_set::index"></a><a name="xpath_node_set::size"></a><a name="xpath_node_set::empty"></a><p>
-        And it also can be iterated via indices, just like <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span></code>:
-      </p>
-<pre class="programlisting"><span class="keyword">const</span> <span class="identifier">xpath_node</span><span class="special">&amp;</span> <span class="identifier">xpath_node_set</span><span class="special">::</span><span class="keyword">operator</span><span class="special">[](</span><span class="identifier">size_t</span> <span class="identifier">index</span><span class="special">)</span> <span class="keyword">const</span><span class="special">;</span>
-<span class="identifier">size_t</span> <span class="identifier">xpath_node_set</span><span class="special">::</span><span class="identifier">size</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>

-</pre>
-<p>
-        All of the above operations have the same semantics as that of <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span></code>:
-        the iterators are random-access, all of the above operations are constant
-        time, and accessing the element at index that is greater or equal than the
-        set size results in undefined behavior. You can use both iterator-based and
-        index-based access for iteration, however the iterator-based one can be faster.

-        The order of iteration depends on the order of nodes inside the set; the
-        order can be queried via the following function:
-      </p>
-<pre class="programlisting"><span class="keyword">enum</span> <span class="identifier">xpath_node_set</span><span class="special">::</span><span class="identifier">type_t</span> <span class="special">{</span><span class="identifier">type_unsorted</span><span class="special">,</span> <span class="identifier">type_sorted</span><span class="special">,</span> <span class="identifier">type_sorted_reverse</span><span class="special">};</span>
-<span class="identifier">type_t</span> <span class="identifier">xpath_node_set</span><span class="special">::</span><span class="identifier">type</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>
-</pre>
-<p>
-        <code class="computeroutput"><span class="identifier">type</span></code> function returns the
-        current order of nodes; <code class="computeroutput"><span class="identifier">type_sorted</span></code>
-        means that the nodes are in forward document order, <code class="computeroutput"><span class="identifier">type_sorted_reverse</span></code>
-        means that the nodes are in reverse document order, and <code class="computeroutput"><span class="identifier">type_unsorted</span></code>
-        means that neither order is guaranteed (nodes can accidentally be in a sorted
-        order even if <code class="computeroutput"><span class="identifier">type</span><span class="special">()</span></code>
-        returns <code class="computeroutput"><span class="identifier">type_unsorted</span></code>). If
-        you require a specific order of iteration, you can change it via <code class="computeroutput"><span class="identifier">sort</span></code> function:
-      </p>
-<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">xpath_node_set</span><span class="special">::</span><span class="identifier">sort</span><span class="special">(</span><span class="keyword">bool</span> <span class="identifier">reverse</span> <span class="special">=</span> <span class="keyword">false</span><span class="special">);</span>
-</pre>
-<p>
-        Calling <code class="computeroutput"><span class="identifier">sort</span></code> sorts the nodes
-        in either forward or reverse document order, depending on the argument; after
-        this call <code class="computeroutput"><span class="identifier">type</span><span class="special">()</span></code>
-        will return <code class="computeroutput"><span class="identifier">type_sorted</span></code> or
-        <code class="computeroutput"><span class="identifier">type_sorted_reverse</span></code>.
-      </p>
-<a name="xpath_node_set::first"></a><p>
-        Often the actual iteration is not needed; instead, only the first element
-        in document order is required. For this, a special accessor is provided:
-      </p>
-<pre class="programlisting"><span class="identifier">xpath_node</span> <span class="identifier">xpath_node_set</span><span class="special">::</span><span class="identifier">first</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>
-</pre>
-<p>
-        This function returns the first node in forward document order from the set,
-        or null node if the set is empty. Note that while the result of the node
-        does not depend on the order of nodes in the set (i.e. on the result of
-        <code class="computeroutput"><span class="identifier">type</span><span class="special">()</span></code>),
-        the complexity does - if the set is sorted, the complexity is constant, otherwise
-        it is linear in the number of elements or worse.
-      </p>
-<a name="xpath_node_set::ctor"></a><p>
-        While in the majority of cases the node set is returned by XPath functions,
-        sometimes there is a need to manually construct a node set. For such cases,
-        a constructor is provided which takes an iterator range (<code class="computeroutput"><span class="identifier">const_iterator</span></code>
-        is a typedef for <code class="computeroutput"><span class="keyword">const</span> <span class="identifier">xpath_node</span><span class="special">*</span></code>), and an optional type:
-      </p>
-<pre class="programlisting"><span class="identifier">xpath_node_set</span><span class="special">::</span><span class="identifier">xpath_node_set</span><span class="special">(</span><span class="identifier">const_iterator</span> <span class="identifier">begin</span><span class="special">,</span> <span class="identifier">const_iterator</span> <span class="identifier">end</span><span class="special">,</span> <span class="identifier">type_t</span> <span class="identifier">type</span> <span class="special">=</span> <span class="identifier">type_unsorted</span><span class="special">);</span>
-</pre>
-<p>
-        The constructor copies the specified range and sets the specified type. The
-        objects in the range are not checked in any way; you'll have to ensure that
-        the range contains no duplicates, and that the objects are sorted according
-        to the <code class="computeroutput"><span class="identifier">type</span></code> parameter. Otherwise
-        XPath operations with this set may produce unexpected results.

-        When you call <code class="computeroutput"><span class="identifier">select_nodes</span></code>
-        with an expression string as an argument, a query object is created behind
-        the scenes. A query object represents a compiled XPath expression. Query
-        objects can be needed in the following circumstances:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">

-        Query objects correspond to <code class="computeroutput"><span class="identifier">xpath_query</span></code>
-        type. They are immutable and non-copyable: they are bound to the expression
-        at creation time and can not be cloned. If you want to put query objects
-        in a container, allocate them on heap via <code class="computeroutput"><span class="keyword">new</span></code>

-        in the container.

-        All functions take the context node as an argument, compute the expression
-        and return the result, converted to the requested type. According to XPath
-        specification, value of any type can be converted to boolean, number or string
-        value, but no type other than node set can be converted to node set. Because
-        of this, <code class="computeroutput"><span class="identifier">evaluate_boolean</span></code>,
-        <code class="computeroutput"><span class="identifier">evaluate_number</span></code> and <code class="computeroutput"><span class="identifier">evaluate_string</span></code> always return a result,

-        XPath queries may contain references to variables; this is useful if you
-        want to use queries that depend on some dynamic parameter without manually
-        preparing the complete query string, or if you want to reuse the same query
-        object for similar queries.
-      </p>
-<p>
-        Variable references have the form <code class="computeroutput"><span class="identifier">$name</span></code>; in order to use them, you have to provide
-        a variable set, which includes all variables present in the query with correct
-        types. This set is passed to <code class="computeroutput"><span class="identifier">xpath_query</span></code>

-        A variable corresponds to the <code class="computeroutput"><span class="identifier">xpath_variable</span></code>
-        type, and a variable handle is simply a pointer to <code class="computeroutput"><span class="identifier">xpath_variable</span></code>.
-      </p>
-<a name="xpath_variable::type"></a><a name="xpath_variable::name"></a><p>
-        In order to get variable information, you can use one of the following functions:

-        Note that each variable has a distinct type which is specified upon variable
-        creation and can not be changed later.

-        In order to get variable value, you should use one of the following functions,

-        These functions return the value of the variable. Note that no type conversions
-        are performed; if the type mismatch occurs, a dummy value is returned (<code class="computeroutput"><span class="keyword">false</span></code> for booleans, <code class="computeroutput"><span class="identifier">NaN</span></code>
-        for numbers, empty string for strings and empty set for node sets).

-</pre>
-<p>
-        These functions modify the variable value. Note that no type conversions
-        are performed; if the type mismatch occurs, the functions return <code class="computeroutput"><span class="keyword">false</span></code>; they also return <code class="computeroutput"><span class="keyword">false</span></code>
-        on allocation failure. The variable values are copied to the internal variable
-        storage, so you can modify or destroy them after the functions return.

-<a name="manual.xpath.errors"></a><a class="link" href="xpath.html#manual.xpath.errors" title="Error handling"> Error handling</a>
-</h3></div></div></div>
-<p>
-        There are two different mechanisms for error handling in XPath implementation;
-        the mechanism used depends on whether exception support is disabled (this
-        is controlled with <a class="link" href="install.html#PUGIXML_NO_EXCEPTIONS">PUGIXML_NO_EXCEPTIONS</a>
-        define).
-      </p>
-<a name="xpath_exception"></a><a name="xpath_exception::result"></a><a name="xpath_exception::what"></a><p>
-        By default, XPath functions throw <code class="computeroutput"><span class="identifier">xpath_exception</span></code>
-        object in case of errors; additionally, in the event any memory allocation
-        fails, an <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">bad_alloc</span></code> exception is thrown. Also <code class="computeroutput"><span class="identifier">xpath_exception</span></code> is thrown if the query
-        is evaluated to a node set, but the return type is not node set. If the query
-        constructor succeeds (i.e. no exception is thrown), the query object is valid.
-        Otherwise you can get the error details via one of the following functions:
-      </p>
-<pre class="programlisting"><span class="keyword">virtual</span> <span class="keyword">const</span> <span class="keyword">char</span><span class="special">*</span> <span class="identifier">xpath_exception</span><span class="special">::</span><span class="identifier">what</span><span class="special">()</span> <span class="keyword">const</span> <span class="keyword">throw</span><span class="special">();</span>
-<span class="keyword">const</span> <span class="identifier">xpath_parse_result</span><span class="special">&amp;</span> <span class="identifier">xpath_exception</span><span class="special">::</span><span class="identifier">result</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>
-</pre>
-<a name="xpath_query::unspecified_bool_type"></a><a name="xpath_query::result"></a><p>
-        If exceptions are disabled, then in the event of parsing failure the query
-        is initialized to invalid state; you can test if the query object is valid
-        by using it in a boolean expression: <code class="computeroutput"><span class="keyword">if</span>
-        <span class="special">(</span><span class="identifier">query</span><span class="special">)</span> <span class="special">{</span> <span class="special">...</span>
-        <span class="special">}</span></code>. Additionally, you can get parsing
-        result via the result() accessor:
-      </p>
-<pre class="programlisting"><span class="keyword">const</span> <span class="identifier">xpath_parse_result</span><span class="special">&amp;</span> <span class="identifier">xpath_query</span><span class="special">::</span><span class="identifier">result</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>
-</pre>
-<p>
-        Without exceptions, evaluating invalid query results in <code class="computeroutput"><span class="keyword">false</span></code>,
-        empty string, NaN or an empty node set, depending on the type; evaluating
-        a query as a node set results in an empty node set if the return type is
-        not node set.
-      </p>
-<a name="xpath_parse_result"></a><p>
-        The information about parsing result is returned via <code class="computeroutput"><span class="identifier">xpath_parse_result</span></code>
-        object. It contains parsing status and the offset of last successfully parsed
-        character from the beginning of the source stream:
-      </p>
-<pre class="programlisting"><span class="keyword">struct</span> <span class="identifier">xpath_parse_result</span>

-<span class="special">};</span>
-</pre>
-<a name="xpath_parse_result::error"></a><p>
-        Parsing result is represented as the error message; it is either a null pointer,
-        in case there is no error, or the error message in the form of ASCII zero-terminated
-        string.
-      </p>
-<a name="xpath_parse_result::description"></a><p>
-        <code class="computeroutput"><span class="identifier">description</span><span class="special">()</span></code>
-        member function can be used to get the error message; it never returns the
-        null pointer, so you can safely use <code class="computeroutput"><span class="identifier">description</span><span class="special">()</span></code> even if query parsing succeeded. Note that
-        <code class="computeroutput"><span class="identifier">description</span><span class="special">()</span></code>
-        returns a <code class="computeroutput"><span class="keyword">char</span></code> string even in
-        <code class="computeroutput"><span class="identifier">PUGIXML_WCHAR_MODE</span></code>; you'll
-        have to call <a class="link" href="dom.html#as_wide">as_wide</a> to get the <code class="computeroutput"><span class="keyword">wchar_t</span></code> string.
-      </p>
-<a name="xpath_parse_result::offset"></a><p>
-        In addition to the error message, parsing result has an <code class="computeroutput"><span class="identifier">offset</span></code>
-        member, which contains the offset of last successfully parsed character.
-        This offset is in units of <a class="link" href="dom.html#char_t">pugi::char_t</a> (bytes
-        for character mode, wide characters for wide character mode).
-      </p>
-<a name="xpath_parse_result::bool"></a><p>
-        Parsing result object can be implicitly converted to <code class="computeroutput"><span class="keyword">bool</span></code>
-        like this: <code class="computeroutput"><span class="keyword">if</span> <span class="special">(</span><span class="identifier">result</span><span class="special">)</span> <span class="special">{</span> <span class="special">...</span> <span class="special">}</span>

-        <a href="http://pugixml.org/" target="_top">pugixml</a> is a light-weight C++ XML
-        processing library. It consists of a DOM-like interface with rich traversal/modification
-        capabilities, an extremely fast XML parser which constructs the DOM tree
-        from an XML file/buffer, and an XPath 1.0 implementation for complex data-driven
-        tree queries. Full Unicode support is also available, with Unicode interface
-        variants and conversions between different Unicode encodings (which happen
-        automatically during parsing/saving). The library is extremely portable and
-        easy to integrate and use. pugixml is developed and maintained since 2006
-        and has many users. All code is distributed under the <a class="link" href="quickstart.html#quickstart.main.license" title="License">MIT
-        license</a>, making it completely free to use in both open-source and
-        proprietary applications.
-      </p>
-<p>
-        pugixml enables very fast, convenient and memory-efficient XML document processing.
-        However, since pugixml has a DOM parser, it can't process XML documents that
-        do not fit in memory; also the parser is a non-validating one, so if you
-        need DTD/Schema validation, the library is not for you.
-      </p>
-<p>
-        This is the quick start guide for pugixml, which purpose is to enable you
-        to start using the library quickly. Many important library features are either
-        not described at all or only mentioned briefly; for more complete information
-        you <a href="manual.html" target="_top">should read the complete manual</a>.

-        pugixml is distributed in source form. You can download a source distribution
-        via one of the following links:
-      </p>
-<pre class="programlisting"><a href="https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.zip" target="_top">https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.zip</a>

-</pre>
-<p>
-        The distribution contains library source, documentation (the guide you're
-        reading now and the manual) and some code examples. After downloading the
-        distribution, install pugixml by extracting all files from the compressed
-        archive. The files have different line endings depending on the archive format
-        - <code class="filename">.zip</code> archive has Windows line endings, <code class="filename">.tar.gz</code> archive has Unix line endings.
-        Otherwise the files in both archives are identical.
-      </p>
-<p>
-        The complete pugixml source consists of three files - one source file, <code class="filename">pugixml.cpp</code>,
-        and two header files, <code class="filename">pugixml.hpp</code> and <code class="filename">pugiconfig.hpp</code>. <code class="filename">pugixml.hpp</code> is the primary
-        header which you need to include in order to use pugixml classes/functions.
-        The rest of this guide assumes that <code class="filename">pugixml.hpp</code> is either in the current directory
-        or in one of include directories of your projects, so that <code class="computeroutput"><span class="preprocessor">#include</span> <span class="string">"pugixml.hpp"</span></code>
-        can find the header; however you can also use relative path (i.e. <code class="computeroutput"><span class="preprocessor">#include</span> <span class="string">"../libs/pugixml/src/pugixml.hpp"</span></code>)
-        or include directory-relative path (i.e. <code class="computeroutput"><span class="preprocessor">#include</span>
-        <span class="special">&lt;</span><span class="identifier">xml</span><span class="special">/</span><span class="identifier">thirdparty</span><span class="special">/</span><span class="identifier">pugixml</span><span class="special">/</span><span class="identifier">src</span><span class="special">/</span><span class="identifier">pugixml</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">&gt;</span></code>).
-      </p>
-<p>
-        The easiest way to build pugixml is to compile the source file, <code class="filename">pugixml.cpp</code>,
-        along with the existing library/executable. This process depends on the method
-        of building your application; for example, if you're using Microsoft Visual
-        Studio<a href="#ftn.trademarks" class="footnote" name="trademarks"><sup class="footnote">[1]</sup></a>,
-        Apple Xcode, Code::Blocks or any other IDE, just add <code class="filename">pugixml.cpp</code> to one of
-        your projects. There are other building methods available, including building
-        pugixml as a standalone static/shared library; <a href="manual/install.html#manual.install.building" target="_top">read
-        the manual</a> for further information.

-<p>
-        pugixml stores XML data in DOM-like way: the entire XML document (both document
-        structure and element data) is stored in memory as a tree. The tree can be
-        loaded from character stream (file, string, C++ I/O stream), then traversed
-        via special API or XPath expressions. The whole tree is mutable: both node
-        structure and node/attribute data can be changed at any time. Finally, the
-        result of document transformations can be saved to a character stream (file,
-        C++ I/O stream or custom transport).
-      </p>
-<p>
-        The root of the tree is the document itself, which corresponds to C++ type
-        <code class="computeroutput"><span class="identifier">xml_document</span></code>. Document has
-        one or more child nodes, which correspond to C++ type <code class="computeroutput"><span class="identifier">xml_node</span></code>.
-        Nodes have different types; depending on a type, a node can have a collection
-        of child nodes, a collection of attributes, which correspond to C++ type
-        <code class="computeroutput"><span class="identifier">xml_attribute</span></code>, and some additional
-        data (i.e. name).
-      </p>
-<p>
-        The most common node types are:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
-<li class="listitem">
-            Document node (<code class="computeroutput"><span class="identifier">node_document</span></code>)
-            - this is the root of the tree, which consists of several child nodes.
-            This node corresponds to <code class="computeroutput"><span class="identifier">xml_document</span></code>
-            class; note that <code class="computeroutput"><span class="identifier">xml_document</span></code>
-            is a sub-class of <code class="computeroutput"><span class="identifier">xml_node</span></code>,
-            so the entire node interface is also available.
-          </li>
-<li class="listitem">
-            Element/tag node (<code class="computeroutput"><span class="identifier">node_element</span></code>)
-            - this is the most common type of node, which represents XML elements.
-            Element nodes have a name, a collection of attributes and a collection
-            of child nodes (both of which may be empty). The attribute is a simple
-            name/value pair.
-          </li>
-<li class="listitem">
-            Plain character data nodes (<code class="computeroutput"><span class="identifier">node_pcdata</span></code>)
-            represent plain text in XML. PCDATA nodes have a value, but do not have
-            name or children/attributes. Note that <span class="bold"><strong>plain character
-            data is not a part of the element node but instead has its own node</strong></span>;
-            for example, an element node can have several child PCDATA nodes.
-          </li>
-</ul></div>
-<p>
-        Despite the fact that there are several node types, there are only three
-        C++ types representing the tree (<code class="computeroutput"><span class="identifier">xml_document</span></code>,
-        <code class="computeroutput"><span class="identifier">xml_node</span></code>, <code class="computeroutput"><span class="identifier">xml_attribute</span></code>);
-        some operations on <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        are only valid for certain node types. They are described below.

-        <code class="computeroutput"><span class="identifier">xml_document</span></code> is the owner
-        of the entire document structure; destroying the document destroys the whole
-        tree. The interface of <code class="computeroutput"><span class="identifier">xml_document</span></code>
-        consists of loading functions, saving functions and the entire interface
-        of <code class="computeroutput"><span class="identifier">xml_node</span></code>, which allows
-        for document inspection and/or modification. Note that while <code class="computeroutput"><span class="identifier">xml_document</span></code> is a sub-class of <code class="computeroutput"><span class="identifier">xml_node</span></code>, <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        is not a polymorphic type; the inheritance is present only to simplify usage.
-      </p>
-<p>
-        <code class="computeroutput"><span class="identifier">xml_node</span></code> is the handle to
-        document node; it can point to any node in the document, including document
-        itself. There is a common interface for nodes of all types. Note that <code class="computeroutput"><span class="identifier">xml_node</span></code> is only a handle to the actual
-        node, not the node itself - you can have several <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        handles pointing to the same underlying object. Destroying <code class="computeroutput"><span class="identifier">xml_node</span></code> handle does not destroy the node
-        and does not remove it from the tree.
-      </p>
-<p>
-        There is a special value of <code class="computeroutput"><span class="identifier">xml_node</span></code>
-        type, known as null node or empty node. It does not correspond to any node
-        in any document, and thus resembles null pointer. However, all operations
-        are defined on empty nodes; generally the operations don't do anything and
-        return empty nodes/attributes or empty strings as their result. This is useful
-        for chaining calls; i.e. you can get the grandparent of a node like so:
-        <code class="computeroutput"><span class="identifier">node</span><span class="special">.</span><span class="identifier">parent</span><span class="special">().</span><span class="identifier">parent</span><span class="special">()</span></code>;
-        if a node is a null node or it does not have a parent, the first <code class="computeroutput"><span class="identifier">parent</span><span class="special">()</span></code>
-        call returns null node; the second <code class="computeroutput"><span class="identifier">parent</span><span class="special">()</span></code> call then also returns null node, so you
-        don't have to check for errors twice. You can test if a handle is null via
-        implicit boolean cast: <code class="computeroutput"><span class="keyword">if</span> <span class="special">(</span><span class="identifier">node</span><span class="special">)</span> <span class="special">{</span> <span class="special">...</span> <span class="special">}</span></code>
-        or <code class="computeroutput"><span class="keyword">if</span> <span class="special">(!</span><span class="identifier">node</span><span class="special">)</span> <span class="special">{</span> <span class="special">...</span> <span class="special">}</span></code>.
-      </p>
-<p>
-        <code class="computeroutput"><span class="identifier">xml_attribute</span></code> is the handle
-        to an XML attribute; it has the same semantics as <code class="computeroutput"><span class="identifier">xml_node</span></code>,
-        i.e. there can be several <code class="computeroutput"><span class="identifier">xml_attribute</span></code>
-        handles pointing to the same underlying object and there is a special null
-        attribute value, which propagates to function results.
-      </p>
-<p>
-        There are two choices of interface and internal representation when configuring
-        pugixml: you can either choose the UTF-8 (also called char) interface or
-        UTF-16/32 (also called wchar_t) one. The choice is controlled via <code class="computeroutput"><span class="identifier">PUGIXML_WCHAR_MODE</span></code> define; you can set
-        it via <code class="filename">pugiconfig.hpp</code> or via preprocessor options. All tree functions that
-        work with strings work with either C-style null terminated strings or STL
-        strings of the selected character type. <a href="manual/dom.html#manual.dom.unicode" target="_top">Read

-        pugixml provides several functions for loading XML data from various places
-        - files, C++ iostreams, memory buffers. All functions use an extremely fast
-        non-validating parser. This parser is not fully W3C conformant - it can load
-        any valid XML document, but does not perform some well-formedness checks.
-        While considerable effort is made to reject invalid XML documents, some validation
-        is not performed because of performance reasons. XML data is always converted
-        to internal character format before parsing. pugixml supports all popular
-        Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and
-        little endian); UCS-2 is naturally supported since it's a strict subset of
-        UTF-16) and handles all encoding conversions automatically.
-      </p>
-<p>
-        The most common source of XML data is files; pugixml provides a separate
-        function for loading XML document from file. This function accepts file path
-        as its first argument, and also two optional arguments, which specify parsing
-        options and input data encoding, which are described in the manual.

-        returned in an <code class="computeroutput"><span class="identifier">xml_parse_result</span></code>

-        Sometimes XML data should be loaded from some other source than file, i.e.
-        HTTP URL; also you may want to load XML data from file using non-standard
-        functions, i.e. to use your virtual file system facilities or to load XML
-        from gzip-compressed files. These scenarios either require loading document
-        from memory, in which case you should prepare a contiguous memory block with
-        all XML data and to pass it to one of buffer loading functions, or loading
-        document from C++ IOstream, in which case you should provide an object which
-        implements <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">istream</span></code> or <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">wistream</span></code>
-        interface.
-      </p>
-<p>
-        There are different functions for loading document from memory; they treat
-        the passed buffer as either an immutable one (<code class="computeroutput"><span class="identifier">load_buffer</span></code>),
-        a mutable buffer which is owned by the caller (<code class="computeroutput"><span class="identifier">load_buffer_inplace</span></code>),
-        or a mutable buffer which ownership belongs to pugixml (<code class="computeroutput"><span class="identifier">load_buffer_inplace_own</span></code>).
-        There is also a simple helper function, <code class="computeroutput"><span class="identifier">xml_document</span><span class="special">::</span><span class="identifier">load</span></code>,
-        for cases when you want to load the XML document from null-terminated character
-        string.
-      </p>

-        pugixml features an extensive interface for getting various types of data
-        from the document and for traversing the document. You can use various accessors
-        to get node/attribute data, you can traverse the child node/attribute lists
-        via accessors or iterators, you can do depth-first traversals with <code class="computeroutput"><span class="identifier">xml_tree_walker</span></code> objects, and you can use
-        XPath for complex data-driven queries.
-      </p>
-<p>
-        You can get node or attribute name via <code class="computeroutput"><span class="identifier">name</span><span class="special">()</span></code> accessor, and value via <code class="computeroutput"><span class="identifier">value</span><span class="special">()</span></code> accessor. Note that both functions never
-        return null pointers - they either return a string with the relevant content,
-        or an empty string if name/value is absent or if the handle is null. Also
-        there are two notable things for reading values:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
-<li class="listitem">
-            It is common to store data as text contents of some node - i.e. <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">node</span><span class="special">&gt;&lt;</span><span class="identifier">description</span><span class="special">&gt;</span><span class="identifier">This</span>
-            <span class="identifier">is</span> <span class="identifier">a</span>

-            In this case, <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">description</span><span class="special">&gt;</span></code> node does not have a value, but instead
-            has a child of type <code class="computeroutput"><span class="identifier">node_pcdata</span></code>
-            with value <code class="computeroutput"><span class="string">"This is a node"</span></code>.
-            pugixml provides <code class="computeroutput"><span class="identifier">child_value</span><span class="special">()</span></code> and <code class="computeroutput"><span class="identifier">text</span><span class="special">()</span></code> helper functions to parse such data.
-          </li>
-<li class="listitem">
-            In many cases attribute values have types that are not strings - i.e.
-            an attribute may always contain values that should be treated as integers,
-            despite the fact that they are represented as strings in XML. pugixml
-            provides several accessors that convert attribute value to some other

-        The document in pugixml is fully mutable: you can completely change the document
-        structure and modify the data of nodes/attributes. All functions take care
-        of memory management and structural integrity themselves, so they always
-        result in structurally valid tree - however, it is possible to create an
-        invalid XML tree (for example, by adding two attributes with the same name
-        or by setting attribute/node name to empty/invalid string). Tree modification
-        is optimized for performance and for memory consumption, so if you have enough
-        memory you can create documents from scratch with pugixml and later save
-        them to file/stream instead of relying on error-prone manual text writing
-        and without too much overhead.
-      </p>
-<p>
-        All member functions that change node/attribute data or structure are non-constant
-        and thus can not be called on constant handles. However, you can easily convert
-        constant handle to non-constant one by simple assignment: <code class="computeroutput"><span class="keyword">void</span>
-        <span class="identifier">foo</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">pugi</span><span class="special">::</span><span class="identifier">xml_node</span><span class="special">&amp;</span> <span class="identifier">n</span><span class="special">)</span> <span class="special">{</span> <span class="identifier">pugi</span><span class="special">::</span><span class="identifier">xml_node</span> <span class="identifier">nc</span> <span class="special">=</span> <span class="identifier">n</span><span class="special">;</span> <span class="special">}</span></code>, so const-correctness
-        here mainly provides additional documentation.
-      </p>
-<p>
-        As discussed before, nodes can have name and value, both of which are strings.
-        Depending on node type, name or value may be absent. You can use <code class="computeroutput"><span class="identifier">set_name</span></code> and <code class="computeroutput"><span class="identifier">set_value</span></code>
-        member functions to set them. Similar functions are available for attributes;
-        however, the <code class="computeroutput"><span class="identifier">set_value</span></code> function
-        is overloaded for some other types except strings, like floating-point numbers.
-        Also, attribute value can be set using an assignment operator. This is an
-        example of setting node/attribute name and value (<a href="samples/modify_base.cpp" target="_top">samples/modify_base.cpp</a>):

-        Nodes and attributes do not exist without a document tree, so you can't create
-        them without adding them to some document. A node or attribute can be created
-        at the end of node/attribute list or before/after some other node. All insertion
-        functions return the handle to newly created object on success, and null
-        handle on failure. Even if the operation fails (for example, if you're trying
-        to add a child node to PCDATA node), the document remains in consistent state,
-        but the requested node/attribute is not added.

-        Often after creating a new document or loading the existing one and processing
-        it, it is necessary to save the result back to file. Also it is occasionally
-        useful to output the whole document or a subtree to some stream; use cases
-        include debug printing, serialization via network or other text-oriented
-        medium, etc. pugixml provides several functions to output any subtree of
-        the document to a file, stream or another generic transport interface; these
-        functions allow to customize the output format, and also perform necessary
-        encoding conversions.

-        Before writing to the destination the node/attribute data is properly formatted
-        according to the node type; all special XML symbols, such as &lt; and &amp;,
-        are properly escaped. In order to guard against forgotten node/attribute
-        names, empty node/attribute names are printed as <code class="computeroutput"><span class="string">":anonymous"</span></code>.
-        For well-formed output, make sure all node and attribute names are set to
-        meaningful values.
-      </p>
-<p>
-        If you want to save the whole document to a file, you can use the <code class="computeroutput"><span class="identifier">save_file</span></code> function, which returns <code class="computeroutput"><span class="keyword">true</span></code> on success. This is a simple example
-        of saving XML document to file (<a href="samples/save_file.cpp" target="_top">samples/save_file.cpp</a>):
-      </p>

-        To enhance interoperability pugixml provides functions for saving document
-        to any object which implements C++ <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">ostream</span></code>
-        interface. This allows you to save documents to any standard C++ stream (i.e.
-        file stream) or any third-party compliant implementation (i.e. Boost Iostreams).
-        Most notably, this allows for easy debug output, since you can use <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">cout</span></code>
-        stream as saving target. There are two functions, one works with narrow character
-        streams, another handles wide character ones.
-      </p>
-<p>
-        This is a simple example of saving XML document to standard output (<a href="samples/save_stream.cpp" target="_top">samples/save_stream.cpp</a>):
-      </p>
-<p>
-        
-</p>
-<pre class="programlisting"><span class="comment">// save document to standard output
-</span><span class="identifier">std</span><span class="special">::</span><span class="identifier">cout</span> <span class="special">&lt;&lt;</span> <span class="string">"Document:\n"</span><span class="special">;</span>
-<span class="identifier">doc</span><span class="special">.</span><span class="identifier">save</span><span class="special">(</span><span class="identifier">std</span><span class="special">::</span><span class="identifier">cout</span><span class="special">);</span>
-</pre>
-<p>
-      </p>
-<p>
-        All of the above saving functions are implemented in terms of writer interface.
-        This is a simple interface with a single function, which is called several
-        times during output process with chunks of document data as input. In order
-        to output the document via some custom transport, for example sockets, you
-        should create an object which implements <code class="computeroutput"><span class="identifier">xml_writer_file</span></code>
-        interface and pass it to <code class="computeroutput"><span class="identifier">xml_document</span><span class="special">::</span><span class="identifier">save</span></code>
-        function.
-      </p>
-<p>
-        This is a simple example of custom writer for saving document data to STL
-        string (<a href="samples/save_custom_writer.cpp" target="_top">samples/save_custom_writer.cpp</a>);
-        read the sample code for more complex examples:
-      </p>
-<p>
-        
-</p>
-<pre class="programlisting"><span class="keyword">struct</span> <span class="identifier">xml_string_writer</span><span class="special">:</span> <span class="identifier">pugi</span><span class="special">::</span><span class="identifier">xml_writer</span>
-<span class="special">{</span>
-    <span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span> <span class="identifier">result</span><span class="special">;</span>
-
-    <span class="keyword">virtual</span> <span class="keyword">void</span> <span class="identifier">write</span><span class="special">(</span><span class="keyword">const</span> <span class="keyword">void</span><span class="special">*</span> <span class="identifier">data</span><span class="special">,</span> <span class="identifier">size_t</span> <span class="identifier">size</span><span class="special">)</span>
-    <span class="special">{</span>
-        <span class="identifier">result</span><span class="special">.</span><span class="identifier">append</span><span class="special">(</span><span class="keyword">static_cast</span><span class="special">&lt;</span><span class="keyword">const</span> <span class="keyword">char</span><span class="special">*&gt;(</span><span class="identifier">data</span><span class="special">),</span> <span class="identifier">size</span><span class="special">);</span>
-    <span class="special">}</span>
-<span class="special">};</span>
-</pre>
-<p>
-      </p>
-<p>
-        While the previously described functions save the whole document to the destination,
-        it is easy to save a single subtree. Instead of calling <code class="computeroutput"><span class="identifier">xml_document</span><span class="special">::</span><span class="identifier">save</span></code>,
-        just call <code class="computeroutput"><span class="identifier">xml_node</span><span class="special">::</span><span class="identifier">print</span></code> function on the target node. You
-        can save node contents to C++ IOstream object or custom writer in this way.
-        Saving a subtree slightly differs from saving the whole document; <a href="manual/saving.html#manual.saving.subtree" target="_top">read the manual</a> for
-        more information.

 The tree nodes can be of one of the following types (which together form the enumeration `xml_node_type`):
 
 * Document node ([anchor node_document]) - this is the root of the tree, which consists of several child nodes. This node corresponds to [link xml_document] class; note that [link xml_document] is a sub-class of [link xml_node], so the entire node interface is also available. However, document node is special in several ways, which are covered below. There can be only one document node in the tree; document node does not have any XML representation.
-[lbr]
 
 * Element/tag node ([anchor node_element]) - this is the most common type of node, which represents XML elements. Element nodes have a name, a collection of attributes and a collection of child nodes (both of which may be empty). The attribute is a simple name/value pair. The example XML representation of element nodes is as follows:
-
++
 ----
 <node attr="value"><child/></node>
 ----

-[:There are two element nodes here: one has name `"node"`, single attribute `"attr"` and single child `"child"`, another has name `"child"` and does not have any attributes or child nodes.]

+There are two element nodes here: one has name `"node"`, single attribute `"attr"` and single child `"child"`, another has name `"child"` and does not have any attributes or child nodes.
 
 * Plain character data nodes ([anchor node_pcdata]) represent plain text in XML. PCDATA nodes have a value, but do not have a name or children/attributes. Note that *plain character data is not a part of the element node but instead has its own node*; an element node can have several child PCDATA nodes. The example XML representation of text nodes is as follows:
-
++
 ----
 <node> text1 <child/> text2 </node>

++
+Here `"node"` element has three children, two of which are PCDATA nodes with values `" text1 "` and `" text2 "`.
 
 * Character data nodes ([anchor node_cdata]) represent text in XML that is quoted in a special way. CDATA nodes do not differ from PCDATA nodes except in XML representation - the above text example looks like this with CDATA:
-

 * `PUGIXML_MEMORY_PAGE_SIZE` controls the page size for document memory allocation. Memory for node/attribute objects is allocated in pages of the specified size. The default size is 32 Kb; for some applications the size is too large (i.e. embedded systems with little heap space or applications that keep lots of XML documents in memory). A minimum size of 1 Kb is recommended.
-[lbr]
 
 * `PUGIXML_MEMORY_OUTPUT_STACK` controls the cumulative stack space required to output the node. Any output operation (i.e. saving a subtree to file) uses an internal buffering scheme for performance reasons. The default size is 10 Kb; if you're using node output from threads with little stack space, decreasing this value can prevent stack overflows. A minimum size of 1 Kb is recommended.

 * `PUGIXML_MEMORY_XPATH_PAGE_SIZE` controls the page size for XPath memory allocation. Memory for XPath query objects as well as internal memory for XPath evaluation is allocated in pages of the specified size.

 * [anchor parse_trim_pcdata] determines if leading and trailing whitespace characters are to be removed from PCDATA nodes.

 * [anchor parse_ws_pcdata] determines if PCDATA nodes (nodes with type [link node_pcdata]) that consist only of whitespace characters are to be put in DOM tree. Often whitespace-only data is not significant for the application, and the cost of allocating and storing such nodes (both memory and speed-wise) can be significant. For example, after parsing XML string `<node> <a/> </node>`, `<node>` element will have three children when `parse_ws_pcdata` is set (child with type [link node_pcdata] and value `" "`, child with type [link node_element] and name `"a"`, and another child with type [link node_pcdata] and value `" "`), and only one child when `parse_ws_pcdata` is not set.

In some cases application needs to parse the whitespace-only contents of nodes, i.e. `<node>  </node>`, but is not interested in whitespace markup elsewhere. It is possible to use [link parse_ws_pcdata] flag in this case, but it results in excessive allocations and complicates document processing in some cases; this flag is intended to avoid that. As an example, after parsing XML string `<node> <a>  </a> </node>` with `parse_ws_pcdata_single` flag set, `<node>` element will have one child `<a>`, and `<a>` element will have one child with type [link node_pcdata] and value `"  "`.

 [#xml_encoding]
 pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it's a strict subset of UTF-16) and handles all encoding conversions. Most loading functions accept the optional parameter `encoding`. This is a value of enumeration type `xml_encoding`, that can have the following values:
 
-* [anchor encoding_auto] means that pugixml will try to guess the encoding based on source XML data. The algorithm is a modified version of the one presented in Appendix F.1 of XML recommendation; it tries to match the first few bytes of input data with the following patterns in strict order:
-    * If first four bytes match UTF-32 BOM (Byte Order Mark), encoding is assumed to be UTF-32 with the endianness equal to that of BOM;
-    * If first two bytes match UTF-16 BOM, encoding is assumed to be UTF-16 with the endianness equal to that of BOM;
-    * If first three bytes match UTF-8 BOM, encoding is assumed to be UTF-8;
-    * If first four bytes match UTF-32 representation of [^<], encoding is assumed to be UTF-32 with the corresponding endianness;
-    * If first four bytes match UTF-16 representation of [^<?], encoding is assumed to be UTF-16 with the corresponding endianness;
-    * If first two bytes match UTF-16 representation of [^<], encoding is assumed to be UTF-16 with the corresponding endianness (this guess may yield incorrect result, but it's better than UTF-8);
-    * Otherwise encoding is assumed to be UTF-8.

 [#xml_parse_result::description]
 `description()` member function can be used to convert parsing status to a string; the returned message is always in English, so you'll have to write your own function if you need a localized string. However please note that the exact messages returned by `description()` function may change from version to version, so any complex status handling should be based on `status` value. Note that `description()` returns a `char` string even in `PUGIXML_WCHAR_MODE`; you'll have to call [link as_wide] to get the `wchar_t` string.
 
-If parsing failed because the source data was not a valid XML, the resulting tree is not destroyed - despite the fact that load function returns error, you can use the part of the tree that was successfully parsed. Obviously, the last element may have an unexpected name/value; for example, if the attribute value does not end with the necessary quotation mark, like in [^<node attr="value>some data</node>] example, the value of attribute `attr` will contain the string `value>some data</node>`.

 [#xml_parse_result::offset]
 In addition to the status code, parsing result has an `offset` member, which contains the offset of last successfully parsed character if parsing failed because of an error in source data; otherwise `offset` is 0. For parsing efficiency reasons, pugixml does not track the current line during parsing; this offset is in units of [link char_t pugi::char_t] (bytes for character mode, wide characters for wide character mode). Many text editors support 'Go To Position' feature - you can use it to locate the exact error position. Alternatively, if you're loading the document from memory, you can display the error chunk along with the error description (see the example code below).

 If your C{plus}{plus} compiler supports range-based for-loop (this is a C{plus}{plus}11 feature, at the time of writing it's supported by Microsoft Visual Studio 11 Beta, GCC 4.6 and Clang 3.0), you can use it to enumerate nodes/attributes. Additional helpers are provided to support this; note that they are also compatible with http://www.boost.org/libs/foreach/[Boost Foreach], and possibly other pre-C{plus}{plus}11 foreach facilities.

Note that you can also use node object itself in a range-based for construct, which is equivalent to using `children()`.

Subject: docs: Set up cross-referencing and anchors

This is mostly done using regex replaces of original Quickbook markup, plus a
bit of manual fixup for multiple references to the single point from different
lines that AsciiDoc does not seem to handle.

 CAUTION: If you're using STL-related functions, you should use the shared runtime library to ensure that a single heap is used for STL allocations in your application and in pugixml; in MSVC, this means selecting the 'Multithreaded DLL' or 'Multithreaded Debug DLL' to 'Runtime library' property (/MD or /MDd linker switch). You should also make sure that your runtime library choice is consistent between different projects.

 ==== Using pugixml in header-only mode
 
+[[PUGIXML_HEADER_ONLY]]
 It's possible to use pugixml in header-only mode. This means that all source code for pugixml will be included in every translation unit that includes `pugixml.hpp`. This is how most of Boost and STL libraries work.
 
-Note that there are advantages and drawbacks of this approach. Header mode may improve tree traversal/modification performance (because many simple functions will be inlined), if your compiler toolchain does not support link-time optimization, or if you have it turned off (with link-time optimization the performance should be similar to non-header mode). However, since compiler now has to compile pugixml source once for each translation unit that includes it, compilation times may increase noticeably. If you want to use pugixml in header mode but do not need XPath support, you can consider disabling it by using [link PUGIXML_NO_XPATH] define to improve compilation time.

 pugixml uses several defines to control the compilation process. There are two ways to define them: either put the needed definitions to `pugiconfig.hpp` (it has some examples that are commented out) or provide them via compiler command-line. Consistency is important: the definitions should match in all source files that include `pugixml.hpp` (including pugixml sources) throughout the application. Adding defines to `pugiconfig.hpp` lets you guarantee this, unless your macro definition is wrapped in preprocessor `#if`/`#ifdef` directive and this directive is not consistent. `pugiconfig.hpp` will never contain anything but comments, which means that when upgrading to a new version, you can safely leave your modified version intact.

 Despite the fact that there are several node types, there are only three C{plus}{plus} classes representing the tree (`xml_document`, `xml_node`, `xml_attribute`); some operations on `xml_node` are only valid for certain node types. The classes are described below.
 
-[#xml_document]
-[#xml_document::document_element]
+[[xml_document]][[xml_document::document_element]]
 `xml_document` is the owner of the entire document structure; it is a non-copyable class. The interface of `xml_document` consists of loading functions (see <<loading>>), saving functions (see <<saving>>) and the entire interface of `xml_node`, which allows for document inspection and/or modification. Note that while `xml_document` is a sub-class of `xml_node`, `xml_node` is not a polymorphic type; the inheritance is present only to simplify usage. Alternatively you can use the `document_element` function to get the element node that's the immediate child of the document.
 
-[#xml_document::ctor]
-[#xml_document::dtor]
-[#xml_document::reset]
+[[xml_document::ctor]][[xml_document::dtor]][[xml_document::reset]]
 Default constructor of `xml_document` initializes the document to the tree with only a root node (document node). You can then populate it with data using either tree modification functions or loading functions; all loading functions destroy the previous tree with all occupied memory, which puts existing node/attribute handles for this document to invalid state. If you want to destroy the previous tree, you can use the `xml_document::reset` function; it destroys the tree and replaces it with either an empty one or a copy of the specified document. Destructor of `xml_document` also destroys the tree, thus the lifetime of the document object should exceed the lifetimes of any node/attribute handles that point to the tree.
 
 CAUTION: While technically node/attribute handles can be alive when the tree they're referring to is destroyed, calling any member function for these handles results in undefined behavior. Thus it is recommended to make sure that the document is destroyed only after all references to its nodes/attributes are destroyed.
 
-[#xml_node]
-[#xml_node::type]
-`xml_node` is the handle to document node; it can point to any node in the document, including the document node itself. There is a common interface for nodes of all types; the actual [link xml_node_type node type] can be queried via the `xml_node::type()` method. Note that `xml_node` is only a handle to the actual node, not the node itself - you can have several `xml_node` handles pointing to the same underlying object. Destroying `xml_node` handle does not destroy the node and does not remove it from the tree. The size of `xml_node` is equal to that of a pointer, so it is nothing more than a lightweight wrapper around a pointer; you can safely pass or return `xml_node` objects by value without additional overhead.

-[#node_null]
+[[node_null]]
 There is a special value of `xml_node` type, known as null node or empty node (such nodes have type `node_null`). It does not correspond to any node in any document, and thus resembles null pointer. However, all operations are defined on empty nodes; generally the operations don't do anything and return empty nodes/attributes or empty strings as their result (see documentation for specific functions for more detailed information). This is useful for chaining calls; i.e. you can get the grandparent of a node like so: `node.parent().parent()`; if a node is a null node or it does not have a parent, the first `parent()` call returns null node; the second `parent()` call then also returns null node, which makes error handling easier.
 
-[#xml_attribute]
+[[xml_attribute]]
 `xml_attribute` is the handle to an XML attribute; it has the same semantics as `xml_node`, i.e. there can be several `xml_attribute` handles pointing to the same underlying object and there is a special null attribute value, which propagates to function results.
 
-[#xml_attribute::ctor]
-[#xml_node::ctor]
+[[xml_attribute::ctor]][[xml_node::ctor]]
 Both `xml_node` and `xml_attribute` have the default constructor which initializes them to null objects.
 
-[#xml_attribute::comparison]
-[#xml_node::comparison]
+[[xml_attribute::comparison]][[xml_node::comparison]]
 `xml_node` and `xml_attribute` try to behave like pointers, that is, they can be compared with other objects of the same type, making it possible to use them as keys in associative containers. All handles to the same underlying object are equal, and any two handles to different underlying objects are not equal. Null handles only compare as equal to themselves. The result of relational comparison can not be reliably determined from the order of nodes in file or in any other way. Do not use relational comparison operators except for search optimization (i.e. associative container keys).
 
-[#xml_attribute::hash_value]
-[#xml_node::hash_value]
+[[xml_attribute::hash_value]][[xml_node::hash_value]]
 If you want to use `xml_node` or `xml_attribute` objects as keys in hash-based associative containers, you can use the `hash_value` member functions. They return the hash values that are guaranteed to be the same for all handles to the same underlying object. The hash value for null handles is 0.

-[#xml_attribute::empty]
-[#xml_node::empty]
+[[xml_attribute::unspecified_bool_type]][[xml_node::unspecified_bool_type]][[xml_attribute::empty]][[xml_node::empty]]
 Finally handles can be implicitly cast to boolean-like objects, so that you can test if the node/attribute is empty with the following code: `if (node) { ... }` or `if (!node) { ... } else { ... }`. Alternatively you can check if a given `xml_node`/`xml_attribute` handle is null by calling the following methods:

 There is a special type, `pugi::char_t`, that is defined as the character type and depends on the library configuration; it will be also used in the documentation hereafter. There is also a type `pugi::string_t`, which is defined as the STL string of the character type; it corresponds to `std::string` in char mode and to `std::wstring` in wchar_t mode.
 
 In addition to the interface, the internal implementation changes to store XML data as `pugi::char_t`; this means that these two modes have different memory usage characteristics. The conversion to `pugi::char_t` upon document loading and from `pugi::char_t` upon document saving happen automatically, which also carries minor performance penalty. The general advice however is to select the character mode based on usage scenario, i.e. if UTF-8 is inconvenient to process and most of your XML data is non-ASCII, wchar_t mode is probably a better choice.

 All additional memory, such as memory for document structure (node/attribute objects) and memory for node/attribute names/values is allocated in pages on the order of 32 kilobytes; actual objects are allocated inside the pages using a memory management scheme optimized for fast allocation/deallocation of many small objects. Because of the scheme specifics, the pages are only destroyed if all objects inside them are destroyed; also, generally destroying an object does not mean that subsequent object creation will reuse the same memory. This means that it is possible to devise a usage scheme which will lead to higher memory usage than expected; one example is adding a lot of nodes, and them removing all even numbered ones; not a single page is reclaimed in the process. However this is an example specifically crafted to produce unsatisfying behavior; in all practical usage scenarios the memory consumption is less than that of a general-purpose allocator because allocation meta-data is very small in size.

All these scenarios require loading document from memory. First you should prepare a contiguous memory block with all XML data; then you have to invoke one of buffer loading functions.

This copy operation carries a performance penalty, so inplace functions are provided - `load_buffer_inplace` and `load_buffer_inplace_own` store the document data in the buffer, modifying it in the process. In order for the document to stay valid, you have to make sure that the buffer's lifetime exceeds that of the tree if you're using inplace functions. In addition to that, `load_buffer_inplace` does not assume ownership of the buffer, so you'll have to destroy it yourself; `load_buffer_inplace_own` assumes ownership of the buffer and destroys it once it is not needed. This means that if you're using `load_buffer_inplace_own`, you have to allocate memory with pugixml allocation function (you can get it via [link get_memory_allocation_function]).

-[#xml_parse_result::description]
-`description()` member function can be used to convert parsing status to a string; the returned message is always in English, so you'll have to write your own function if you need a localized string. However please note that the exact messages returned by `description()` function may change from version to version, so any complex status handling should be based on `status` value. Note that `description()` returns a `char` string even in `PUGIXML_WCHAR_MODE`; you'll have to call [link as_wide] to get the `wchar_t` string.

 If parsing failed because the source data was not a valid XML, the resulting tree is not destroyed - despite the fact that load function returns error, you can use the part of the tree that was successfully parsed. Obviously, the last element may have an unexpected name/value; for example, if the attribute value does not end with the necessary quotation mark, like in `<node attr="value>some data</node>` example, the value of attribute `attr` will contain the string `value>some data</node>`.
 
-[#xml_parse_result::offset]
-In addition to the status code, parsing result has an `offset` member, which contains the offset of last successfully parsed character if parsing failed because of an error in source data; otherwise `offset` is 0. For parsing efficiency reasons, pugixml does not track the current line during parsing; this offset is in units of [link char_t pugi::char_t] (bytes for character mode, wide characters for wide character mode). Many text editors support 'Go To Position' feature - you can use it to locate the exact error position. Alternatively, if you're loading the document from memory, you can display the error chunk along with the error description (see the example code below).

 Parsing result also has an `encoding` member, which can be used to check that the source data encoding was correctly guessed. It is equal to the exact encoding used during parsing (i.e. with the exact endianness); see <<loading.encoding>> for more information.
 
-[#xml_parse_result::bool]

 Parsing result object can be implicitly converted to `bool`; if you do not want to handle parsing errors thoroughly, you can just check the return value of load functions as if it was a `bool`: `if (doc.load_file("file.xml")) { ... } else { ... }`.

In some cases application needs to parse the whitespace-only contents of nodes, i.e. `<node>  </node>`, but is not interested in whitespace markup elsewhere. It is possible to use [link parse_ws_pcdata] flag in this case, but it results in excessive allocations and complicates document processing in some cases; this flag is intended to avoid that. As an example, after parsing XML string `<node> <a>  </a> </node>` with `parse_ws_pcdata_single` flag set, `<node>` element will have one child `<a>`, and `<a>` element will have one child with type [link node_pcdata] and value `"  "`.

If character/entity reference can not be expanded, it is left as is, so you can do additional processing later. Reference expansion is performed on attribute values and PCDATA content.

This means, that whitespace characters (new line, tab and space) are replaced with space (`' '`).

-* [anchor parse_wnorm_attribute] determines if extended attribute value normalization should be performed for all attributes. This means, that after attribute values are normalized as if [link parse_wconv_attribute] was set, leading and trailing space characters are removed, and all sequences of space characters are replaced by a single space character.

 Additionally there are three predefined option masks:
 
-* [anchor parse_minimal] has all options turned off. This option mask means that pugixml does not add declaration nodes, document type declaration nodes, PI nodes, CDATA sections and comments to the resulting tree and does not perform any conversion for input data, so theoretically it is the fastest mode.

 The internal representation of the document is a tree, where each node has a list of child nodes (the order of children corresponds to their order in the XML representation), and additionally element nodes have a list of attributes, which is also ordered. Several functions are provided in order to let you get from one node in the tree to the other. These functions roughly correspond to the internal representation, and thus are usually building blocks for other methods of traversing (i.e. XPath traversals are based on these functions).

 The first method is more convenient, but slower than the other two. The relative performance of `append_copy` and `append_buffer` depends on the buffer format - usually `append_buffer` is faster if the buffer is in native encoding (UTF-8 or wchar_t, depending on `PUGIXML_WCHAR_MODE`). At the same time it might be less efficient in terms of memory usage - the implementation makes a copy of the provided buffer, and the copy has the same lifetime as the document - the memory used by that copy will be reclaimed after the document is destroyed, but no sooner. Even deleting all nodes in the document, including the appended ones, won't reclaim the memory.

 Often after creating a new document or loading the existing one and processing it, it is necessary to save the result back to file. Also it is occasionally useful to output the whole document or a subtree to some stream; use cases include debug printing, serialization via network or other text-oriented medium, etc. pugixml provides several functions to output any subtree of the document to a file, stream or another generic transport interface; these functions allow to customize the output format (see <<saving.options>>), and also perform necessary encoding conversions (see <<saving.encoding>>).

 Note that there are advantages and drawbacks of this approach. Header mode may improve tree traversal/modification performance (because many simple functions will be inlined), if your compiler toolchain does not support link-time optimization, or if you have it turned off (with link-time optimization the performance should be similar to non-header mode). However, since compiler now has to compile pugixml source once for each translation unit that includes it, compilation times may increase noticeably. If you want to use pugixml in header mode but do not need XPath support, you can consider disabling it by using <<PUGIXML_NO_XPATH,PUGIXML_NO_XPATH>> define to improve compilation time.
 
-Enabling header-only mode is a two-step process:
-
-* You have to define `PUGIXML_HEADER_ONLY`
-* You have to include `pugixml.cpp` whenever you include pugixml.hpp

-[section:overview Overview]
-
-[section:introduction Introduction]
-
-[@http://pugixml.org/ pugixml] is a light-weight C++ XML processing library. It consists of a DOM-like interface with rich traversal/modification capabilities, an extremely fast XML parser which constructs the DOM tree from an XML file/buffer, and an [link manual.xpath XPath 1.0 implementation] for complex data-driven tree queries. Full Unicode support is also available, with [link manual.dom.unicode two Unicode interface variants] and conversions between different Unicode encodings (which happen automatically during parsing/saving). The library is [link manual.install.portability extremely portable] and easy to integrate and use. pugixml is developed and maintained since 2006 and has many users. All code is distributed under the [link manual.overview.license MIT license], making it completely free to use in both open-source and proprietary applications.
-
-pugixml enables very fast, convenient and memory-efficient XML document processing. However, since pugixml has a DOM parser, it can't process XML documents that do not fit in memory; also the parser is a non-validating one, so if you need DTD or XML Schema validation, the library is not for you.
-
-This is the complete manual for pugixml, which describes all features of the library in detail. If you want to start writing code as quickly as possible, you are advised to [@quickstart.html read the quick start guide first].
-
-[note No documentation is perfect, neither is this one. If you encounter a description that is unclear, please file an issue as described in [sref manual.overview.feedback]. Also if you can spare the time for a full proof-reading, including spelling and grammar, that would be great! Please [link email send me an e-mail]; as a token of appreciation, your name will be included into the [link manual.overview.thanks corresponding section] of this documentation.]

-[section:feedback Feedback]
-
-If you believe you've found a bug in pugixml (bugs include compilation problems (errors/warnings), crashes, performance degradation and incorrect behavior), please file an issue via [@https://github.com/zeux/pugixml/issues/new issue submission form]. Be sure to include the relevant information so that the bug can be reproduced: the version of pugixml, compiler version and target architecture, the code that uses pugixml and exhibits the bug, etc.
-
-Feature requests can be reported the same way as bugs, so if you're missing some functionality in pugixml or if the API is rough in some places and you can suggest an improvement, [@https://github.com/zeux/pugixml/issues/new file an issue]. However please note that there are many factors when considering API changes (compatibility with previous versions, API redundancy, etc.), so generally features that can be implemented via a small function without pugixml modification are not accepted. However, all rules have exceptions.
-
-If you have a contribution to pugixml, such as build script for some build system/IDE, or a well-designed set of helper functions, or a binding to some language other than C++, please [@https://github.com/zeux/pugixml/issues/new file an issue]. You can include the relevant patches as issue attachments. Your contribution has to be distributed under the terms of a license that's compatible with pugixml license; i.e. GPL/LGPL licensed code is not accepted.
-
-[#email]
-If filing an issue is not possible due to privacy or other concerns, you can contact pugixml author by e-mail directly: [@mailto:arseny.kapoulkine@gmail.com arseny.kapoulkine@gmail.com].

-[section:install Installation]
-
-[section:getting Getting pugixml]
-
-pugixml is distributed in source form. You can either download a source distribution or clone the Git repository.
-
-[section:source Source distributions]
-
-You can download the latest source distribution via one of the following links:
-
-[pre
-[@https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.zip]
-[@https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.tar.gz]
-]
-
-The distribution contains library source, documentation (the manual you're reading now and the quick start guide) and some code examples. After downloading the distribution, install pugixml by extracting all files from the compressed archive. The files have different line endings depending on the archive format - [file .zip] archive has Windows line endings, [file .tar.gz] archive has Unix line endings. Otherwise the files in both archives are identical.
-
-If you need an older version, you can download it from the [@https://github.com/zeux/pugixml/releases version archive].
-
-[endsect] [/source]
-
-[section:git Git repository]
-
-The Git repository is located at [@https://github.com/zeux/pugixml/]. There is a Git tag "v{version}" for each version; also there is the "latest" tag, which always points to the latest stable release.
-
-For example, to checkout the current version, you can use this command:
-
-[pre
-git clone https://github.com/zeux/pugixml
-cd pugixml
-git checkout v1.6
-]
-
-The repository contains library source, documentation, code examples and full unit test suite.
-
-Use latest version tag if you want to automatically get new versions. Use other tags if you want to switch to new versions only explicitly. Also please note that the master branch contains the work-in-progress version of the code; while this means that you can get new features and bug fixes from master without waiting for a new release, this also means that occasionally the code can be broken in some configurations.
-
-[endsect] [/git]
-
-[section:subversion Subversion repository]
-
-You can access the Git repository via Subversion using [@https://github.com/zeux/pugixml] URL. For example, to checkout the current version, you can use this command:
-
-[pre svn checkout https://github.com/zeux/pugixml/tags/v1.6 pugixml]
-
-[endsect] [/subversion]
-
-[endsect] [/getting]
-
-[section:building Building pugixml]
-
-pugixml is distributed in source form without any pre-built binaries; you have to build them yourself.
- 
-The complete pugixml source consists of three files - one source file, [file pugixml.cpp], and two header files, [file pugixml.hpp] and [file pugiconfig.hpp]. [file pugixml.hpp] is the primary header which you need to include in order to use pugixml classes/functions; [file pugiconfig.hpp] is a supplementary configuration file (see [sref manual.install.building.config]). The rest of this guide assumes that [file pugixml.hpp] is either in the current directory or in one of include directories of your projects, so that `#include "pugixml.hpp"` can find the header; however you can also use relative path (i.e. `#include "../libs/pugixml/src/pugixml.hpp"`) or include directory-relative path (i.e. `#include <xml/thirdparty/pugixml/src/pugixml.hpp>`).
- 
-[section:embed Building pugixml as a part of another static library/executable]
- 
-The easiest way to build pugixml is to compile the source file, [file pugixml.cpp], along with the existing library/executable. This process depends on the method of building your application; for example, if you're using Microsoft Visual Studio[ftnt trademarks All trademarks used are properties of their respective owners.], Apple Xcode, Code::Blocks or any other IDE, just add [file pugixml.cpp] to one of your projects.
-
-If you're using Microsoft Visual Studio and the project has precompiled headers turned on, you'll see the following error messages:
-
-[pre pugixml.cpp(3477) : fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "stdafx.h"' to your source?]
-
-The correct way to resolve this is to disable precompiled headers for [file pugixml.cpp]; you have to set "Create/Use Precompiled Header" option (Properties dialog -> C/C++ -> Precompiled Headers -> Create/Use Precompiled Header) to "Not Using Precompiled Headers". You'll have to do it for all project configurations/platforms (you can select Configuration "All Configurations" and Platform "All Platforms" before editing the option):

-[section:static Building pugixml as a standalone static library]
- 
-It's possible to compile pugixml as a standalone static library. This process depends on the method of building your application; pugixml distribution comes with project files for several popular IDEs/build systems. There are project files for Apple XCode3, Code::Blocks, Codelite, Microsoft Visual Studio 2005, 2008, 2010, and configuration scripts for CMake and premake4.

-There are two projects for each version of Microsoft Visual Studio: one for dynamically linked CRT, which has a name like [file pugixml_vs2008.vcproj], and another one for statically linked CRT, which has a name like [file pugixml_vs2008_static.vcproj]. You should select the version that matches the CRT used in your application; the default option for new projects created by Microsoft Visual Studio is dynamically linked CRT, so unless you changed the defaults, you should use the version with dynamic CRT (i.e. [file pugixml_vs2008.vcproj] for Microsoft Visual Studio 2008).
-
-In addition to adding pugixml project to your workspace, you'll have to make sure that your application links with pugixml library. If you're using Microsoft Visual Studio 2005/2008, you can add a dependency from your application project to pugixml one. If you're using Microsoft Visual Studio 2010, you'll have to add a reference to your application project instead. For other IDEs/systems, consult the relevant documentation.

-[section:shared Building pugixml as a standalone shared library]
- 
-It's possible to compile pugixml as a standalone shared library. The process is usually similar to the static library approach; however, no preconfigured projects/scripts are included into pugixml distribution, so you'll have to do it yourself. Generally, if you're using GCC-based toolchain, the process does not differ from building any other library as DLL (adding -shared to compilation flags should suffice); if you're using MSVC-based toolchain, you'll have to explicitly mark exported symbols with a declspec attribute. You can do it by defining [link PUGIXML_API] macro, i.e. via [file pugiconfig.hpp]:
-
-    #ifdef _DLL
-    #define PUGIXML_API __declspec(dllexport)
-    #else
-    #define PUGIXML_API __declspec(dllimport)
-    #endif
-
-[caution If you're using STL-related functions, you should use the shared runtime library to ensure that a single heap is used for STL allocations in your application and in pugixml; in MSVC, this means selecting the 'Multithreaded DLL' or 'Multithreaded Debug DLL' to 'Runtime library' property (/MD or /MDd linker switch). You should also make sure that your runtime library choice is consistent between different projects.]

-[#PUGIXML_HEADER_ONLY]
-[section:header Using pugixml in header-only mode]
-
-It's possible to use pugixml in header-only mode. This means that all source code for pugixml will be included in every translation unit that includes [file pugixml.hpp]. This is how most of Boost and STL libraries work.
-
-Note that there are advantages and drawbacks of this approach. Header mode may improve tree traversal/modification performance (because many simple functions will be inlined), if your compiler toolchain does not support link-time optimization, or if you have it turned off (with link-time optimization the performance should be similar to non-header mode). However, since compiler now has to compile pugixml source once for each translation unit that includes it, compilation times may increase noticeably. If you want to use pugixml in header mode but do not need XPath support, you can consider disabling it by using [link PUGIXML_NO_XPATH] define to improve compilation time.
-
-Enabling header-only mode is a two-step process:
-
-# You have to define `PUGIXML_HEADER_ONLY`
-# You have to include [file pugixml.cpp] whenever you include pugixml.hpp
-
-Both of these are best done via [file pugiconfig.hpp] like this:
-
-    #define PUGIXML_HEADER_ONLY
-    #include "pugixml.cpp"
-
-Note that it is safe to compile [file pugixml.cpp] if `PUGIXML_HEADER_ONLY` is defined - so if you want to i.e. use header-only mode only in Release configuration, you
-can include pugixml.cpp in your project (see [sref manual.install.building.embed]), and conditionally enable header-only mode in [file pugiconfig.hpp], i.e.:
-
-    #ifndef _DEBUG
-        #define PUGIXML_HEADER_ONLY
-        #include "pugixml.cpp"
-    #endif
-
-[endsect] [/header]
- 
-[section:config Additional configuration options]
-
-pugixml uses several defines to control the compilation process. There are two ways to define them: either put the needed definitions to [file pugiconfig.hpp] (it has some examples that are commented out) or provide them via compiler command-line. Consistency is important: the definitions should match in all source files that include [file pugixml.hpp] (including pugixml sources) throughout the application. Adding defines to [file pugiconfig.hpp] lets you guarantee this, unless your macro definition is wrapped in preprocessor `#if`/`#ifdef` directive and this directive is not consistent. [file pugiconfig.hpp] will never contain anything but comments, which means that when upgrading to a new version, you can safely leave your modified version intact.
-
-[anchor PUGIXML_WCHAR_MODE] define toggles between UTF-8 style interface (the in-memory text encoding is assumed to be UTF-8, most functions use `char` as character type) and UTF-16/32 style interface (the in-memory text encoding is assumed to be UTF-16/32, depending on `wchar_t` size, most functions use `wchar_t` as character type). See [sref manual.dom.unicode] for more details.
-
-[anchor PUGIXML_NO_XPATH] define disables XPath. Both XPath interfaces and XPath implementation are excluded from compilation. This option is provided in case you do not need XPath functionality and need to save code space.
-
-[anchor PUGIXML_NO_STL] define disables use of STL in pugixml. The functions that operate on STL types are no longer present (i.e. load/save via iostream) if this macro is defined. This option is provided in case your target platform does not have a standard-compliant STL implementation.
-
-[anchor PUGIXML_NO_EXCEPTIONS] define disables use of exceptions in pugixml. This option is provided in case your target platform does not have exception handling capabilities.
-
-[anchor PUGIXML_API], [anchor PUGIXML_CLASS] and [anchor PUGIXML_FUNCTION] defines let you specify custom attributes (i.e. declspec or calling conventions) for pugixml classes and non-member functions. In absence of `PUGIXML_CLASS` or `PUGIXML_FUNCTION` definitions, `PUGIXML_API` definition is used instead. For example, to specify fixed calling convention, you can define `PUGIXML_FUNCTION` to i.e. `__fastcall`. Another example is DLL import/export attributes in MSVC (see [sref manual.install.building.shared]).
-
-[note In that example `PUGIXML_API` is inconsistent between several source files; this is an exception to the consistency rule.]
-
-[anchor PUGIXML_MEMORY_PAGE_SIZE], [anchor PUGIXML_MEMORY_OUTPUT_STACK] and [anchor PUGIXML_MEMORY_XPATH_PAGE_SIZE] can be used to customize certain important sizes to optimize memory usage for the application-specific patterns. For details see [sref manual.dom.memory.tuning].
-
-[anchor PUGIXML_HAS_LONG_LONG] define enables support for `long long` type in pugixml. This define is automatically enabled if your platform is known to have `long long` support (i.e. has C++-11 support or uses a reasonably modern version of a known compiler); if pugixml does not recognize that your platform supports `long long` but in fact it does, you can enable the define manually.

-[section:dom Document object model]
-
-pugixml stores XML data in DOM-like way: the entire XML document (both document structure and element data) is stored in memory as a tree. The tree can be loaded from a character stream (file, string, C++ I/O stream), then traversed with the special API or XPath expressions. The whole tree is mutable: both node structure and node/attribute data can be changed at any time. Finally, the result of document transformations can be saved to a character stream (file, C++ I/O stream or custom transport).
-
-[section:tree Tree structure]
-
-The XML document is represented with a tree data structure. The root of the tree is the document itself, which corresponds to C++ type [link xml_document]. Document has one or more child nodes, which correspond to C++ type [link xml_node]. Nodes have different types; depending on a type, a node can have a collection of child nodes, a collection of attributes, which correspond to C++ type [link xml_attribute], and some additional data (i.e. name).
-
-[#xml_node_type]
-The tree nodes can be of one of the following types (which together form the enumeration `xml_node_type`):
-
-* Document node ([anchor node_document]) - this is the root of the tree, which consists of several child nodes. This node corresponds to [link xml_document] class; note that [link xml_document] is a sub-class of [link xml_node], so the entire node interface is also available. However, document node is special in several ways, which are covered below. There can be only one document node in the tree; document node does not have any XML representation.
-[lbr]
-
-* Element/tag node ([anchor node_element]) - this is the most common type of node, which represents XML elements. Element nodes have a name, a collection of attributes and a collection of child nodes (both of which may be empty). The attribute is a simple name/value pair. The example XML representation of element nodes is as follows:
-
-    <node attr="value"><child/></node>
-
-[:There are two element nodes here: one has name `"node"`, single attribute `"attr"` and single child `"child"`, another has name `"child"` and does not have any attributes or child nodes.]
-
-* Plain character data nodes ([anchor node_pcdata]) represent plain text in XML. PCDATA nodes have a value, but do not have a name or children/attributes. Note that *plain character data is not a part of the element node but instead has its own node*; an element node can have several child PCDATA nodes. The example XML representation of text nodes is as follows:
-
-    <node> text1 <child/> text2 </node>
-
-[:Here `"node"` element has three children, two of which are PCDATA nodes with values `" text1 "` and `" text2 "`.]
-
-* Character data nodes ([anchor node_cdata]) represent text in XML that is quoted in a special way. CDATA nodes do not differ from PCDATA nodes except in XML representation - the above text example looks like this with CDATA:
-
-    <node> <![CDATA[[text1]]> <child/> <![CDATA[[text2]]> </node>
-
-[:CDATA nodes make it easy to include non-escaped <, & and > characters in plain text. CDATA value can not contain the character sequence \]\]>, since it is used to determine the end of node contents.]
-
-* Comment nodes ([anchor node_comment]) represent comments in XML. Comment nodes have a value, but do not have a name or children/attributes. The example XML representation of a comment node is as follows:
-
-    <!-- comment text -->
-
-[:Here the comment node has value `"comment text"`. By default comment nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with [link parse_comments] flag.]
-
-* Processing instruction node ([anchor node_pi]) represent processing instructions (PI) in XML. PI nodes have a name and an optional value, but do not have children/attributes. The example XML representation of a PI node is as follows:
-
-    <?name value?>
-
-[:Here the name (also called PI target) is `"name"`, and the value is `"value"`. By default PI nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with [link parse_pi] flag.]
-
-* Declaration node ([anchor node_declaration]) represents document declarations in XML. Declaration nodes have a name (`"xml"`) and an optional collection of attributes, but do not have value or children. There can be only one declaration node in a document; moreover, it should be the topmost node (its parent should be the document). The example XML representation of a declaration node is as follows:
-
-    <?xml version="1.0"?>
-
-[:Here the node has name `"xml"` and a single attribute with name `"version"` and value `"1.0"`. By default declaration nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with [link parse_declaration] flag. Also, by default a dummy declaration is output when XML document is saved unless there is already a declaration in the document; you can disable this with [link format_no_declaration] flag.]
-
-* Document type declaration node ([anchor node_doctype]) represents document type declarations in XML. Document type declaration nodes have a value, which corresponds to the entire document type contents; no additional nodes are created for inner elements like `<!ENTITY>`. There can be only one document type declaration node in a document; moreover, it should be the topmost node (its parent should be the document). The example XML representation of a document type declaration node is as follows:
-
-	<!DOCTYPE greeting [ <!ELEMENT greeting (#PCDATA)> ]>
-
-[:Here the node has value `"greeting [ <!ELEMENT greeting (#PCDATA)> ]"`. By default document type declaration nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with [link parse_doctype] flag.]
-

-[section:cpp C++ interface]
-
-[note All pugixml classes and functions are located in the `pugi` namespace; you have to either use explicit name qualification (i.e. `pugi::xml_node`), or to gain access to relevant symbols via `using` directive (i.e. `using pugi::xml_node;` or `using namespace pugi;`). The namespace will be omitted from all declarations in this documentation hereafter; all code examples will use fully qualified names.]
-
-Despite the fact that there are several node types, there are only three C++ classes representing the tree (`xml_document`, `xml_node`, `xml_attribute`); some operations on `xml_node` are only valid for certain node types. The classes are described below.
-
-[#xml_document]
-[#xml_document::document_element]
-`xml_document` is the owner of the entire document structure; it is a non-copyable class. The interface of `xml_document` consists of loading functions (see [sref manual.loading]), saving functions (see [sref manual.saving]) and the entire interface of `xml_node`, which allows for document inspection and/or modification. Note that while `xml_document` is a sub-class of `xml_node`, `xml_node` is not a polymorphic type; the inheritance is present only to simplify usage. Alternatively you can use the `document_element` function to get the element node that's the immediate child of the document.
-
-[#xml_document::ctor]
-[#xml_document::dtor]
-[#xml_document::reset]
-Default constructor of `xml_document` initializes the document to the tree with only a root node (document node). You can then populate it with data using either tree modification functions or loading functions; all loading functions destroy the previous tree with all occupied memory, which puts existing node/attribute handles for this document to invalid state. If you want to destroy the previous tree, you can use the `xml_document::reset` function; it destroys the tree and replaces it with either an empty one or a copy of the specified document. Destructor of `xml_document` also destroys the tree, thus the lifetime of the document object should exceed the lifetimes of any node/attribute handles that point to the tree.
-
-[caution While technically node/attribute handles can be alive when the tree they're referring to is destroyed, calling any member function for these handles results in undefined behavior. Thus it is recommended to make sure that the document is destroyed only after all references to its nodes/attributes are destroyed.]
-
-[#xml_node]
-[#xml_node::type]
-`xml_node` is the handle to document node; it can point to any node in the document, including the document node itself. There is a common interface for nodes of all types; the actual [link xml_node_type node type] can be queried via the `xml_node::type()` method. Note that `xml_node` is only a handle to the actual node, not the node itself - you can have several `xml_node` handles pointing to the same underlying object. Destroying `xml_node` handle does not destroy the node and does not remove it from the tree. The size of `xml_node` is equal to that of a pointer, so it is nothing more than a lightweight wrapper around a pointer; you can safely pass or return `xml_node` objects by value without additional overhead.
-
-[#node_null]
-There is a special value of `xml_node` type, known as null node or empty node (such nodes have type `node_null`). It does not correspond to any node in any document, and thus resembles null pointer. However, all operations are defined on empty nodes; generally the operations don't do anything and return empty nodes/attributes or empty strings as their result (see documentation for specific functions for more detailed information). This is useful for chaining calls; i.e. you can get the grandparent of a node like so: `node.parent().parent()`; if a node is a null node or it does not have a parent, the first `parent()` call returns null node; the second `parent()` call then also returns null node, which makes error handling easier.
-
-[#xml_attribute]
-`xml_attribute` is the handle to an XML attribute; it has the same semantics as `xml_node`, i.e. there can be several `xml_attribute` handles pointing to the same underlying object and there is a special null attribute value, which propagates to function results.
-
-[#xml_attribute::ctor]
-[#xml_node::ctor]
-Both `xml_node` and `xml_attribute` have the default constructor which initializes them to null objects.
-
-[#xml_attribute::comparison]
-[#xml_node::comparison]
-`xml_node` and `xml_attribute` try to behave like pointers, that is, they can be compared with other objects of the same type, making it possible to use them as keys in associative containers. All handles to the same underlying object are equal, and any two handles to different underlying objects are not equal. Null handles only compare as equal to themselves. The result of relational comparison can not be reliably determined from the order of nodes in file or in any other way. Do not use relational comparison operators except for search optimization (i.e. associative container keys).
-
-[#xml_attribute::hash_value]
-[#xml_node::hash_value]
-If you want to use `xml_node` or `xml_attribute` objects as keys in hash-based associative containers, you can use the `hash_value` member functions. They return the hash values that are guaranteed to be the same for all handles to the same underlying object. The hash value for null handles is 0.
-
-[#xml_attribute::unspecified_bool_type]
-[#xml_node::unspecified_bool_type]
-[#xml_attribute::empty]
-[#xml_node::empty]
-Finally handles can be implicitly cast to boolean-like objects, so that you can test if the node\/attribute is empty with the following code: `if (node) { ... }` or `if (!node) { ... } else { ... }`. Alternatively you can check if a given `xml_node`/`xml_attribute` handle is null by calling the following methods:
-
-    bool xml_attribute::empty() const;
-    bool xml_node::empty() const;
-
-Nodes and attributes do not exist without a document tree, so you can't create them without adding them to some document. Once underlying node/attribute objects are destroyed, the handles to those objects become invalid. While this means that destruction of the entire tree invalidates all node/attribute handles, it also means that destroying a subtree (by calling [link xml_node::remove_child]) or removing an attribute invalidates the corresponding handles. There is no way to check handle validity; you have to ensure correctness through external mechanisms.
-

-
-[section:unicode Unicode interface]
-
-There are two choices of interface and internal representation when configuring pugixml: you can either choose the UTF-8 (also called char) interface or UTF-16/32 (also called wchar_t) one. The choice is controlled via [link PUGIXML_WCHAR_MODE] define; you can set it via [file pugiconfig.hpp] or via preprocessor options, as discussed in [sref manual.install.building.config]. If this define is set, the wchar_t interface is used; otherwise (by default) the char interface is used. The exact wide character encoding is assumed to be either UTF-16 or UTF-32 and is determined based on the size of `wchar_t` type.
-
-[note If the size of `wchar_t` is 2, pugixml assumes UTF-16 encoding instead of UCS-2, which means that some characters are represented as two code points.]
-
-All tree functions that work with strings work with either C-style null terminated strings or STL strings of the selected character type. For example, node name accessors look like this in char mode:
-
-    const char* xml_node::name() const;
-    bool xml_node::set_name(const char* value);
-
-and like this in wchar_t mode:
-
-    const wchar_t* xml_node::name() const;
-    bool xml_node::set_name(const wchar_t* value);
-
-[#char_t]
-[#string_t]
-There is a special type, `pugi::char_t`, that is defined as the character type and depends on the library configuration; it will be also used in the documentation hereafter. There is also a type `pugi::string_t`, which is defined as the STL string of the character type; it corresponds to `std::string` in char mode and to `std::wstring` in wchar_t mode.
-
-In addition to the interface, the internal implementation changes to store XML data as `pugi::char_t`; this means that these two modes have different memory usage characteristics. The conversion to `pugi::char_t` upon document loading and from `pugi::char_t` upon document saving happen automatically, which also carries minor performance penalty. The general advice however is to select the character mode based on usage scenario, i.e. if UTF-8 is inconvenient to process and most of your XML data is non-ASCII, wchar_t mode is probably a better choice.
-
-[#as_utf8]
-[#as_wide]
-There are cases when you'll have to convert string data between UTF-8 and wchar_t encodings; the following helper functions are provided for such purposes:
-
-    std::string as_utf8(const wchar_t* str);
-    std::wstring as_wide(const char* str);
-
-Both functions accept a null-terminated string as an argument `str`, and return the converted string. `as_utf8` performs conversion from UTF-16/32 to UTF-8; `as_wide` performs conversion from UTF-8 to UTF-16/32. Invalid UTF sequences are silently discarded upon conversion. `str` has to be a valid string; passing null pointer results in undefined behavior. There are also two overloads with the same semantics which accept a string as an argument:
-
-    std::string as_utf8(const std::wstring& str);
-    std::wstring as_wide(const std::string& str);
-
-[note Most examples in this documentation assume char interface and therefore will not compile with [link PUGIXML_WCHAR_MODE]. This is done to simplify the documentation; usually the only changes you'll have to make is to pass `wchar_t` string literals, i.e. instead of
-
-`pugi::xml_node node = doc.child("bookstore").find_child_by_attribute("book", "id", "12345");`
-
-you'll have to do
-
-`pugi::xml_node node = doc.child(L"bookstore").find_child_by_attribute(L"book", L"id", L"12345");`]
- 
-[endsect] [/unicode]
-
-[section:thread Thread-safety guarantees]
-
-Almost all functions in pugixml have the following thread-safety guarantees:
-
-* it is safe to call free (non-member) functions from multiple threads
-* it is safe to perform concurrent read-only accesses to the same tree (all constant member functions do not modify the tree)
-* it is safe to perform concurrent read/write accesses, if there is only one read or write access to the single tree at a time
-
-Concurrent modification and traversing of a single tree requires synchronization, for example via reader-writer lock. Modification includes altering document structure and altering individual node/attribute data, i.e. changing names/values.
-
-The only exception is [link set_memory_management_functions]; it modifies global variables and as such is not thread-safe. Its usage policy has more restrictions, see [sref manual.dom.memory.custom].
-
-[endsect] [/thread]
-
-[section:exception Exception guarantees]
-
-With the exception of XPath, pugixml itself does not throw any exceptions. Additionally, most pugixml functions have a no-throw exception guarantee.
-
-This is not applicable to functions that operate on STL strings or IOstreams; such functions have either strong guarantee (functions that operate on strings) or basic guarantee (functions that operate on streams). Also functions that call user-defined callbacks (i.e. [link xml_node::traverse] or [link xml_node::find_node]) do not provide any exception guarantees beyond the ones provided by the callback.
-
-If exception handling is not disabled with [link PUGIXML_NO_EXCEPTIONS] define, XPath functions may throw [link xpath_exception] on parsing errors; also, XPath functions may throw `std::bad_alloc` in low memory conditions. Still, XPath functions provide strong exception guarantee.
-
-[endsect] [/exception]
-
-[section:memory Memory management]
-
-pugixml requests the memory needed for document storage in big chunks, and allocates document data inside those chunks. This section discusses replacing functions used for chunk allocation and internal memory management implementation.
-
-[section:custom Custom memory allocation/deallocation functions]
-
-[#allocation_function]
-[#deallocation_function]
-All memory for tree structure, tree data and XPath objects is allocated via globally specified functions, which default to malloc/free. You can set your own allocation functions with set_memory_management function. The function interfaces are the same as that of malloc/free:
-
-    typedef void* (*allocation_function)(size_t size);
-    typedef void (*deallocation_function)(void* ptr);
-
-[#set_memory_management_functions]
-[#get_memory_allocation_function]
-[#get_memory_deallocation_function]
-You can use the following accessor functions to change or get current memory management functions:
-
-    void set_memory_management_functions(allocation_function allocate, deallocation_function deallocate);
-    allocation_function get_memory_allocation_function();
-    deallocation_function get_memory_deallocation_function();
-
-Allocation function is called with the size (in bytes) as an argument and should return a pointer to a memory block with alignment that is suitable for storage of primitive types (usually a maximum of `void*` and `double` types alignment is sufficient) and size that is greater than or equal to the requested one. If the allocation fails, the function has to return null pointer (throwing an exception from allocation function results in undefined behavior).
-
-Deallocation function is called with the pointer that was returned by some call to allocation function; it is never called with a null pointer. If memory management functions are not thread-safe, library thread safety is not guaranteed.
-
-This is a simple example of custom memory management ([@samples/custom_memory_management.cpp]):
-
-[import samples/custom_memory_management.cpp]
-[code_custom_memory_management_decl]
-[code_custom_memory_management_call]
-
-When setting new memory management functions, care must be taken to make sure that there are no live pugixml objects. Otherwise when the objects are destroyed, the new deallocation function will be called with the memory obtained by the old allocation function, resulting in undefined behavior.

-[section:tuning Memory consumption tuning]
-
-There are several important buffering optimizations in pugixml that rely on predefined constants. These constants have default values that were tuned for common usage patterns; for some applications, changing these constants might improve memory consumption or increase performance. Changing these constants is not recommended unless their default values result in visible problems.
-
-These constants can be tuned via configuration defines, as discussed in [sref manual.install.building.config]; it is recommended to set them in [file pugiconfig.hpp].
-
-* `PUGIXML_MEMORY_PAGE_SIZE` controls the page size for document memory allocation. Memory for node/attribute objects is allocated in pages of the specified size. The default size is 32 Kb; for some applications the size is too large (i.e. embedded systems with little heap space or applications that keep lots of XML documents in memory). A minimum size of 1 Kb is recommended.
-[lbr]
-
-* `PUGIXML_MEMORY_OUTPUT_STACK` controls the cumulative stack space required to output the node. Any output operation (i.e. saving a subtree to file) uses an internal buffering scheme for performance reasons. The default size is 10 Kb; if you're using node output from threads with little stack space, decreasing this value can prevent stack overflows. A minimum size of 1 Kb is recommended.
-[lbr]
-
-* `PUGIXML_MEMORY_XPATH_PAGE_SIZE` controls the page size for XPath memory allocation. Memory for XPath query objects as well as internal memory for XPath evaluation is allocated in pages of the specified size. The default size is 4 Kb; if you have a lot of resident XPath query objects, you might need to decrease the size to improve memory consumption. A minimum size of 256 bytes is recommended.
-
-[endsect] [/tuning]
-
-[section:internals Document memory management internals]
-
-Constructing a document object using the default constructor does not result in any allocations; document node is stored inside the [link xml_document] object.
-
-When the document is loaded from file/buffer, unless an inplace loading function is used (see [sref manual.loading.memory]), a complete copy of character stream is made; all names/values of nodes and attributes are allocated in this buffer. This buffer is allocated via a single large allocation and is only freed when document memory is reclaimed (i.e. if the [link xml_document] object is destroyed or if another document is loaded in the same object). Also when loading from file or stream, an additional large allocation may be performed if encoding conversion is required; a temporary buffer is allocated, and it is freed before load function returns.
-
-All additional memory, such as memory for document structure (node/attribute objects) and memory for node/attribute names/values is allocated in pages on the order of 32 kilobytes; actual objects are allocated inside the pages using a memory management scheme optimized for fast allocation/deallocation of many small objects. Because of the scheme specifics, the pages are only destroyed if all objects inside them are destroyed; also, generally destroying an object does not mean that subsequent object creation will reuse the same memory. This means that it is possible to devise a usage scheme which will lead to higher memory usage than expected; one example is adding a lot of nodes, and them removing all even numbered ones; not a single page is reclaimed in the process. However this is an example specifically crafted to produce unsatisfying behavior; in all practical usage scenarios the memory consumption is less than that of a general-purpose allocator because allocation meta-data is very small in size.

-[section:loading Loading document]
-
-pugixml provides several functions for loading XML data from various places - files, C++ iostreams, memory buffers. All functions use an extremely fast non-validating parser. This parser is not fully W3C conformant - it can load any valid XML document, but does not perform some well-formedness checks. While considerable effort is made to reject invalid XML documents, some validation is not performed for performance reasons. Also some XML transformations (i.e. EOL handling or attribute value normalization) can impact parsing speed and thus can be disabled. However for vast majority of XML documents there is no performance difference between different parsing options. Parsing options also control whether certain XML nodes are parsed; see [sref manual.loading.options] for more information.
-
-XML data is always converted to internal character format (see [sref manual.dom.unicode]) before parsing. pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it's a strict subset of UTF-16) and handles all encoding conversions automatically. Unless explicit encoding is specified, loading functions perform automatic encoding detection based on first few characters of XML data, so in almost all cases you do not have to specify document encoding. Encoding conversion is described in more detail in [sref manual.loading.encoding].
-
-[section:file Loading document from file]
-
-[#xml_document::load_file]
-[#xml_document::load_file_wide]
-The most common source of XML data is files; pugixml provides dedicated functions for loading an XML document from file:
-
-    xml_parse_result xml_document::load_file(const char* path, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
-    xml_parse_result xml_document::load_file(const wchar_t* path, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
-    
-These functions accept the file path as its first argument, and also two optional arguments, which specify parsing options (see [sref manual.loading.options]) and input data encoding (see [sref manual.loading.encoding]). The path has the target operating system format, so it can be a relative or absolute one, it should have the delimiters of the target system, it should have the exact case if the target file system is case-sensitive, etc.
-
-File path is passed to the system file opening function as is in case of the first function (which accepts `const char* path`); the second function either uses a special file opening function if it is provided by the runtime library or converts the path to UTF-8 and uses the system file opening function.
-
-`load_file` destroys the existing document tree and then tries to load the new tree from the specified file. The result of the operation is returned in an [link xml_parse_result] object; this object contains the operation status and the related information (i.e. last successfully parsed position in the input file, if parsing fails). See [sref manual.loading.errors] for error handling details.
-
-This is an example of loading XML document from file ([@samples/load_file.cpp]):
-
-[import samples/load_file.cpp]

-
-[section:memory Loading document from memory]
-
-[#xml_document::load_buffer]
-[#xml_document::load_buffer_inplace]
-[#xml_document::load_buffer_inplace_own]
-Sometimes XML data should be loaded from some other source than a file, i.e. HTTP URL; also you may want to load XML data from file using non-standard functions, i.e. to use your virtual file system facilities or to load XML from gzip-compressed files. All these scenarios require loading document from memory. First you should prepare a contiguous memory block with all XML data; then you have to invoke one of buffer loading functions. These functions will handle the necessary encoding conversions, if any, and then will parse the data into the corresponding XML tree. There are several buffer loading functions, which differ in the behavior and thus in performance/memory usage:
-
-    xml_parse_result xml_document::load_buffer(const void* contents, size_t size, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
-    xml_parse_result xml_document::load_buffer_inplace(void* contents, size_t size, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
-    xml_parse_result xml_document::load_buffer_inplace_own(void* contents, size_t size, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
-
-All functions accept the buffer which is represented by a pointer to XML data, `contents`, and data size in bytes. Also there are two optional arguments, which specify parsing options (see [sref manual.loading.options]) and input data encoding (see [sref manual.loading.encoding]). The buffer does not have to be zero-terminated.
-
-`load_buffer` function works with immutable buffer - it does not ever modify the buffer. Because of this restriction it has to create a private buffer and copy XML data to it before parsing (applying encoding conversions if necessary). This copy operation carries a performance penalty, so inplace functions are provided - `load_buffer_inplace` and `load_buffer_inplace_own` store the document data in the buffer, modifying it in the process. In order for the document to stay valid, you have to make sure that the buffer's lifetime exceeds that of the tree if you're using inplace functions. In addition to that, `load_buffer_inplace` does not assume ownership of the buffer, so you'll have to destroy it yourself; `load_buffer_inplace_own` assumes ownership of the buffer and destroys it once it is not needed. This means that if you're using `load_buffer_inplace_own`, you have to allocate memory with pugixml allocation function (you can get it via [link get_memory_allocation_function]).
-
-The best way from the performance/memory point of view is to load document using `load_buffer_inplace_own`; this function has maximum control of the buffer with XML data so it is able to avoid redundant copies and reduce peak memory usage while parsing. This is the recommended function if you have to load the document from memory and performance is critical.
-
-[#xml_document::load_string]
-There is also a simple helper function for cases when you want to load the XML document from null-terminated character string:
-
-    xml_parse_result xml_document::load_string(const char_t* contents, unsigned int options = parse_default);
-
-It is equivalent to calling `load_buffer` with `size` being either `strlen(contents)` or `wcslen(contents) * sizeof(wchar_t)`, depending on the character type. This function assumes native encoding for input data, so it does not do any encoding conversion. In general, this function is fine for loading small documents from string literals, but has more overhead and less functionality than the buffer loading functions.
-
-This is an example of loading XML document from memory using different functions ([@samples/load_memory.cpp]):

-[code_load_memory_decl]
-[code_load_memory_buffer]
-[code_load_memory_buffer_inplace]

-
-[section:stream Loading document from C++ IOstreams]
-
-[#xml_document::load_stream]
-To enhance interoperability, pugixml provides functions for loading document from any object which implements C++ `std::istream` interface. This allows you to load documents from any standard C++ stream (i.e. file stream) or any third-party compliant implementation (i.e. Boost Iostreams). There are two functions, one works with narrow character streams, another handles wide character ones:
-
-    xml_parse_result xml_document::load(std::istream& stream, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
-    xml_parse_result xml_document::load(std::wistream& stream, unsigned int options = parse_default);
-
-`load` with `std::istream` argument loads the document from stream from the current read position to the end, treating the stream contents as a byte stream of the specified encoding (with encoding autodetection as necessary). Thus calling `xml_document::load` on an opened `std::ifstream` object is equivalent to calling `xml_document::load_file`.
-
-`load` with `std::wstream` argument treats the stream contents as a wide character stream (encoding is always [link encoding_wchar]). Because of this, using `load` with wide character streams requires careful (usually platform-specific) stream setup (i.e. using the `imbue` function). Generally use of wide streams is discouraged, however it provides you the ability to load documents from non-Unicode encodings, i.e. you can load Shift-JIS encoded data if you set the correct locale.
-
-This is a simple example of loading XML document from file using streams ([@samples/load_stream.cpp]); read the sample code for more complex examples involving wide streams and locales:
-
-[import samples/load_stream.cpp]
-[code_load_stream]
-
-[endsect] [/stream]
-
-[section:errors Handling parsing errors]
-
-[#xml_parse_result]
-All document loading functions return the parsing result via `xml_parse_result` object. It contains parsing status, the offset of last successfully parsed character from the beginning of the source stream, and the encoding of the source stream:
-
-    struct xml_parse_result
-    {
-        xml_parse_status status;
-        ptrdiff_t offset;
-        xml_encoding encoding;
-
-        operator bool() const;
-        const char* description() const;
-    };
-
-[#xml_parse_status]
-[#xml_parse_result::status]
-Parsing status is represented as the `xml_parse_status` enumeration and can be one of the following:
-
-* [anchor status_ok] means that no error was encountered during parsing; the source stream represents the valid XML document which was fully parsed and converted to a tree.
-[lbr]
-
-* [anchor status_file_not_found] is only returned by `load_file` function and means that file could not be opened.
-* [anchor status_io_error] is returned by `load_file` function and by `load` functions with `std::istream`/`std::wstream` arguments; it means that some I/O error has occurred during reading the file/stream.
-* [anchor status_out_of_memory] means that there was not enough memory during some allocation; any allocation failure during parsing results in this error.
-* [anchor status_internal_error] means that something went horribly wrong; currently this error does not occur
-[lbr]
-
-* [anchor status_unrecognized_tag] means that parsing stopped due to a tag with either an empty name or a name which starts with incorrect character, such as [^#].
-* [anchor status_bad_pi] means that parsing stopped due to incorrect document declaration/processing instruction
-* [anchor status_bad_comment], [anchor status_bad_cdata], [anchor status_bad_doctype] and [anchor status_bad_pcdata] mean that parsing stopped due to the invalid construct of the respective type
-* [anchor status_bad_start_element] means that parsing stopped because starting tag either had no closing `>` symbol or contained some incorrect symbol
-* [anchor status_bad_attribute] means that parsing stopped because there was an incorrect attribute, such as an attribute without value or with value that is not quoted (note that `<node attr=1>` is incorrect in XML)
-* [anchor status_bad_end_element] means that parsing stopped because ending tag had incorrect syntax (i.e. extra non-whitespace symbols between tag name and `>`)
-* [anchor status_end_element_mismatch] means that parsing stopped because the closing tag did not match the opening one (i.e. `<node></nedo>`) or because some tag was not closed at all
-* [anchor status_no_document_element] means that no element nodes were discovered during parsing; this usually indicates an empty or invalid document
-
-[#xml_parse_result::description]
-`description()` member function can be used to convert parsing status to a string; the returned message is always in English, so you'll have to write your own function if you need a localized string. However please note that the exact messages returned by `description()` function may change from version to version, so any complex status handling should be based on `status` value. Note that `description()` returns a `char` string even in `PUGIXML_WCHAR_MODE`; you'll have to call [link as_wide] to get the `wchar_t` string.
-
-If parsing failed because the source data was not a valid XML, the resulting tree is not destroyed - despite the fact that load function returns error, you can use the part of the tree that was successfully parsed. Obviously, the last element may have an unexpected name/value; for example, if the attribute value does not end with the necessary quotation mark, like in [^<node attr="value>some data</node>] example, the value of attribute `attr` will contain the string `value>some data</node>`.
-
-[#xml_parse_result::offset]
-In addition to the status code, parsing result has an `offset` member, which contains the offset of last successfully parsed character if parsing failed because of an error in source data; otherwise `offset` is 0. For parsing efficiency reasons, pugixml does not track the current line during parsing; this offset is in units of [link char_t pugi::char_t] (bytes for character mode, wide characters for wide character mode). Many text editors support 'Go To Position' feature - you can use it to locate the exact error position. Alternatively, if you're loading the document from memory, you can display the error chunk along with the error description (see the example code below).
-
-[caution Offset is calculated in the XML buffer in native encoding; if encoding conversion is performed during parsing, offset can not be used to reliably track the error position.]
-
-[#xml_parse_result::encoding]
-Parsing result also has an `encoding` member, which can be used to check that the source data encoding was correctly guessed. It is equal to the exact encoding used during parsing (i.e. with the exact endianness); see [sref manual.loading.encoding] for more information.
-
-[#xml_parse_result::bool]
-Parsing result object can be implicitly converted to `bool`; if you do not want to handle parsing errors thoroughly, you can just check the return value of load functions as if it was a `bool`: `if (doc.load_file("file.xml")) { ... } else { ... }`.

-[endsect] [/errors]
-
-[section:options Parsing options]
-
-All document loading functions accept the optional parameter `options`. This is a bitmask that customizes the parsing process: you can select the node types that are parsed and various transformations that are performed with the XML text. Disabling certain transformations can improve parsing performance for some documents; however, the code for all transformations is very well optimized, and thus the majority of documents won't get any performance benefit. As a rule of thumb, only modify parsing flags if you want to get some nodes in the document that are excluded by default (i.e. declaration or comment nodes).
-
-[note You should use the usual bitwise arithmetics to manipulate the bitmask: to enable a flag, use `mask | flag`; to disable a flag, use `mask & ~flag`.]
-
-These flags control the resulting tree contents:
-
-* [anchor parse_declaration] determines if XML document declaration (node with type [link node_declaration]) is to be put in DOM tree. If this flag is off, it is not put in the tree, but is still parsed and checked for correctness. This flag is *off* by default.
-[lbr]
-
-* [anchor parse_doctype] determines if XML document type declaration (node with type [link node_doctype]) is to be put in DOM tree. If this flag is off, it is not put in the tree, but is still parsed and checked for correctness. This flag is *off* by default.
-[lbr]
-
-* [anchor parse_pi] determines if processing instructions (nodes with type [link node_pi]) are to be put in DOM tree. If this flag is off, they are not put in the tree, but are still parsed and checked for correctness. Note that `<?xml ...?>` (document declaration) is not considered to be a PI. This flag is *off* by default.
-[lbr]
-
-* [anchor parse_comments] determines if comments (nodes with type [link node_comment]) are to be put in DOM tree. If this flag is off, they are not put in the tree, but are still parsed and checked for correctness. This flag is *off* by default.
-[lbr]
-
-* [anchor parse_cdata] determines if CDATA sections (nodes with type [link node_cdata]) are to be put in DOM tree. If this flag is off, they are not put in the tree, but are still parsed and checked for correctness. This flag is *on* by default.
-[lbr]
-
-* [anchor parse_trim_pcdata] determines if leading and trailing whitespace characters are to be removed from PCDATA nodes. While for some applications leading/trailing whitespace is significant, often the application only cares about the non-whitespace contents so it's easier to trim whitespace from text during parsing. This flag is *off* by default.
-[lbr]
-
-* [anchor parse_ws_pcdata] determines if PCDATA nodes (nodes with type [link node_pcdata]) that consist only of whitespace characters are to be put in DOM tree. Often whitespace-only data is not significant for the application, and the cost of allocating and storing such nodes (both memory and speed-wise) can be significant. For example, after parsing XML string `<node> <a/> </node>`, `<node>` element will have three children when `parse_ws_pcdata` is set (child with type [link node_pcdata] and value `" "`, child with type [link node_element] and name `"a"`, and another child with type [link node_pcdata] and value `" "`), and only one child when `parse_ws_pcdata` is not set. This flag is *off* by default.
-[lbr]
-
-* [anchor parse_ws_pcdata_single] determines if whitespace-only PCDATA nodes that have no sibling nodes are to be put in DOM tree. In some cases application needs to parse the whitespace-only contents of nodes, i.e. `<node>  </node>`, but is not interested in whitespace markup elsewhere. It is possible to use [link parse_ws_pcdata] flag in this case, but it results in excessive allocations and complicates document processing in some cases; this flag is intended to avoid that. As an example, after parsing XML string `<node> <a>  </a> </node>` with `parse_ws_pcdata_single` flag set, `<node>` element will have one child `<a>`, and `<a>` element will have one child with type [link node_pcdata] and value `"  "`. This flag has no effect if [link parse_ws_pcdata] is enabled. This flag is *off* by default.
-[lbr]
-
-* [anchor parse_fragment] determines if document should be treated as a fragment of a valid XML. Parsing document as a fragment leads to top-level PCDATA content (i.e. text that is not located inside a node) to be added to a tree, and additionally treats documents without element nodes as valid. This flag is *off* by default.
-
-[caution Using in-place parsing ([link xml_document::load_buffer_inplace load_buffer_inplace]) with `parse_fragment` flag may result in the loss of the last character of the buffer if it is a part of PCDATA. Since PCDATA values are null-terminated strings, the only way to resolve this is to provide a null-terminated buffer as an input to `load_buffer_inplace` - i.e. `doc.load_buffer_inplace("test\0", 5, pugi::parse_default | pugi::parse_fragment)`.]
-
-These flags control the transformation of tree element contents:
-
-* [anchor parse_escapes] determines if character and entity references are to be expanded during the parsing process. Character references have the form [^&#...;] or [^&#x...;] ([^...] is Unicode numeric representation of character in either decimal ([^&#...;]) or hexadecimal ([^&#x...;]) form), entity references are [^&lt;], [^&gt;], [^&amp;], [^&apos;] and [^&quot;] (note that as pugixml does not handle DTD, the only allowed entities are predefined ones). If character/entity reference can not be expanded, it is left as is, so you can do additional processing later. Reference expansion is performed on attribute values and PCDATA content. This flag is *on* by default.
-[lbr]
-
-* [anchor parse_eol] determines if EOL handling (that is, replacing sequences `0x0d 0x0a` by a single `0x0a` character, and replacing all standalone `0x0d` characters by `0x0a`) is to be performed on input data (that is, comments contents, PCDATA/CDATA contents and attribute values). This flag is *on* by default.
-[lbr]
-
-* [anchor parse_wconv_attribute] determines if attribute value normalization should be performed for all attributes. This means, that whitespace characters (new line, tab and space) are replaced with space (`' '`). New line characters are always treated as if [link parse_eol] is set, i.e. `\r\n` is converted to a single space.  This flag is *on* by default.
-[lbr]
-
-* [anchor parse_wnorm_attribute] determines if extended attribute value normalization should be performed for all attributes. This means, that after attribute values are normalized as if [link parse_wconv_attribute] was set, leading and trailing space characters are removed, and all sequences of space characters are replaced by a single space character. [link parse_wconv_attribute] has no effect if this flag is on. This flag is *off* by default.
-
-[note `parse_wconv_attribute` option performs transformations that are required by W3C specification for attributes that are declared as [^CDATA]; [link parse_wnorm_attribute] performs transformations required for [^NMTOKENS] attributes. In the absence of document type declaration all attributes should behave as if they are declared as [^CDATA], thus [link parse_wconv_attribute] is the default option.]
-
-Additionally there are three predefined option masks:
-
-* [anchor parse_minimal] has all options turned off. This option mask means that pugixml does not add declaration nodes, document type declaration nodes, PI nodes, CDATA sections and comments to the resulting tree and does not perform any conversion for input data, so theoretically it is the fastest mode. However, as mentioned above, in practice [link parse_default] is usually equally fast.
-[lbr]
-
-* [anchor parse_default] is the default set of flags, i.e. it has all options set to their default values. It includes parsing CDATA sections (comments/PIs are not parsed), performing character and entity reference expansion, replacing whitespace characters with spaces in attribute values and performing EOL handling. Note, that PCDATA sections consisting only of whitespace characters are not parsed (by default) for performance reasons.
-[lbr]
-
-* [anchor parse_full] is the set of flags which adds nodes of all types to the resulting tree and performs default conversions for input data. It includes parsing CDATA sections, comments, PI nodes, document declaration node and document type declaration node, performing character and entity reference expansion, replacing whitespace characters with spaces in attribute values and performing EOL handling. Note, that PCDATA sections consisting only of whitespace characters are not parsed in this mode.

-[section:encoding Encodings]
-
-[#xml_encoding]
-pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it's a strict subset of UTF-16) and handles all encoding conversions. Most loading functions accept the optional parameter `encoding`. This is a value of enumeration type `xml_encoding`, that can have the following values:
-
-* [anchor encoding_auto] means that pugixml will try to guess the encoding based on source XML data. The algorithm is a modified version of the one presented in Appendix F.1 of XML recommendation; it tries to match the first few bytes of input data with the following patterns in strict order:
-[lbr]
-    * If first four bytes match UTF-32 BOM (Byte Order Mark), encoding is assumed to be UTF-32 with the endianness equal to that of BOM;
-    * If first two bytes match UTF-16 BOM, encoding is assumed to be UTF-16 with the endianness equal to that of BOM;
-    * If first three bytes match UTF-8 BOM, encoding is assumed to be UTF-8;
-    * If first four bytes match UTF-32 representation of [^<], encoding is assumed to be UTF-32 with the corresponding endianness;
-    * If first four bytes match UTF-16 representation of [^<?], encoding is assumed to be UTF-16 with the corresponding endianness;
-    * If first two bytes match UTF-16 representation of [^<], encoding is assumed to be UTF-16 with the corresponding endianness (this guess may yield incorrect result, but it's better than UTF-8);
-    * Otherwise encoding is assumed to be UTF-8.
-    [lbr]
-
-* [anchor encoding_utf8] corresponds to UTF-8 encoding as defined in the Unicode standard; UTF-8 sequences with length equal to 5 or 6 are not standard and are rejected.
-* [anchor encoding_utf16_le] corresponds to little-endian UTF-16 encoding as defined in the Unicode standard; surrogate pairs are supported.
-* [anchor encoding_utf16_be] corresponds to big-endian UTF-16 encoding as defined in the Unicode standard; surrogate pairs are supported.
-* [anchor encoding_utf16] corresponds to UTF-16 encoding as defined in the Unicode standard; the endianness is assumed to be that of the target platform.
-* [anchor encoding_utf32_le] corresponds to little-endian UTF-32 encoding as defined in the Unicode standard.
-* [anchor encoding_utf32_be] corresponds to big-endian UTF-32 encoding as defined in the Unicode standard.
-* [anchor encoding_utf32] corresponds to UTF-32 encoding as defined in the Unicode standard; the endianness is assumed to be that of the target platform.
-* [anchor encoding_wchar] corresponds to the encoding of `wchar_t` type; it has the same meaning as either `encoding_utf16` or `encoding_utf32`, depending on `wchar_t` size.
-* [anchor encoding_latin1] corresponds to ISO-8859-1 encoding (also known as Latin-1).
-
-The algorithm used for `encoding_auto` correctly detects any supported Unicode encoding for all well-formed XML documents (since they start with document declaration) and for all other XML documents that start with [^<]; if your XML document does not start with [^<] and has encoding that is different from UTF-8, use the specific encoding.
-
-[note The current behavior for Unicode conversion is to skip all invalid UTF sequences during conversion. This behavior should not be relied upon; moreover, in case no encoding conversion is performed, the invalid sequences are not removed, so you'll get them as is in node/attribute contents.]

-[section:w3c Conformance to W3C specification]
-
-pugixml is not fully W3C conformant - it can load any valid XML document, but does not perform some well-formedness checks. While considerable effort is made to reject invalid XML documents, some validation is not performed because of performance reasons.
-
-There is only one non-conformant behavior when dealing with valid XML documents: pugixml does not use information supplied in document type declaration for parsing. This means that entities declared in DOCTYPE are not expanded, and all attribute/PCDATA values are always processed in a uniform way that depends only on parsing options.
-
-As for rejecting invalid XML documents, there are a number of incompatibilities with W3C specification, including:
-
-* Multiple attributes of the same node can have equal names.
-* All non-ASCII characters are treated in the same way as symbols of English alphabet, so some invalid tag names are not rejected.
-* Attribute values which contain [^<] are not rejected.
-* Invalid entity/character references are not rejected and are instead left as is.
-* Comment values can contain [^--].
-* XML data is not required to begin with document declaration; additionally, document declaration can appear after comments and other nodes.
-* Invalid document type declarations are silently ignored in some cases.

-[section:access Accessing document data]
-
-pugixml features an extensive interface for getting various types of data from the document and for traversing the document. This section provides documentation for all such functions that do not modify the tree except for XPath-related functions; see [sref manual.xpath] for XPath reference. As discussed in [sref manual.dom.cpp], there are two types of handles to tree data - [link xml_node] and [link xml_attribute]. The handles have special null (empty) values which propagate through various functions and thus are useful for writing more concise code; see [link node_null this description] for details. The documentation in this section will explicitly state the results of all function in case of null inputs.
-

-[section:basic Basic traversal functions]
-
-[#xml_node::parent][#xml_node::first_child][#xml_node::last_child][#xml_node::next_sibling][#xml_node::previous_sibling][#xml_node::first_attribute][#xml_node::last_attribute][#xml_attribute::next_attribute][#xml_attribute::previous_attribute]
-The internal representation of the document is a tree, where each node has a list of child nodes (the order of children corresponds to their order in the XML representation), and additionally element nodes have a list of attributes, which is also ordered. Several functions are provided in order to let you get from one node in the tree to the other. These functions roughly correspond to the internal representation, and thus are usually building blocks for other methods of traversing (i.e. XPath traversals are based on these functions).
-
-    xml_node xml_node::parent() const;
-    xml_node xml_node::first_child() const;
-    xml_node xml_node::last_child() const;
-    xml_node xml_node::next_sibling() const;
-    xml_node xml_node::previous_sibling() const;
-
-    xml_attribute xml_node::first_attribute() const;
-    xml_attribute xml_node::last_attribute() const;
-    xml_attribute xml_attribute::next_attribute() const;
-    xml_attribute xml_attribute::previous_attribute() const;
-
-`parent` function returns the node's parent; all non-null nodes except the document have non-null parent. `first_child` and `last_child` return the first and last child of the node, respectively; note that only document nodes and element nodes can have non-empty child node list. If node has no children, both functions return null nodes. `next_sibling` and `previous_sibling` return the node that's immediately to the right\/left of this node in the children list, respectively - for example, in `<a/><b/><c/>`, calling `next_sibling` for a handle that points to `<b/>` results in a handle pointing to `<c/>`, and calling `previous_sibling` results in handle pointing to `<a/>`. If node does not have next/previous sibling (this happens if it is the last/first node in the list, respectively), the functions return null nodes. `first_attribute`, `last_attribute`, `next_attribute` and `previous_attribute` functions behave similarly to the corresponding child node functions and allow to iterate through attribute list in the same way.
-
-[note Because of memory consumption reasons, attributes do not have a link to their parent nodes. Thus there is no `xml_attribute::parent()` function.]
-
-Calling any of the functions above on the null handle results in a null handle - i.e. `node.first_child().next_sibling()` returns the second child of `node`, and null handle if `node` is null, has no children at all or if it has only one child node.
-
-With these functions, you can iterate through all child nodes and display all attributes like this ([@samples/traverse_base.cpp]):

-[section:nodedata Getting node data]
-
-[#xml_node::name][#xml_node::value]
-Apart from structural information (parent, child nodes, attributes), nodes can have name and value, both of which are strings. Depending on node type, name or value may be absent. [link node_document] nodes do not have a name or value, [link node_element] and [link node_declaration] nodes always have a name but never have a value, [link node_pcdata], [link node_cdata], [link node_comment] and [link node_doctype] nodes never have a name but always have a value (it may be empty though), [link node_pi] nodes always have a name and a value (again, value may be empty). In order to get node's name or value, you can use the following functions:
-
-    const char_t* xml_node::name() const;
-    const char_t* xml_node::value() const;
-
-In case node does not have a name or value or if the node handle is null, both functions return empty strings - they never return null pointers.
-
-[#xml_node::child_value]
-It is common to store data as text contents of some node - i.e. `<node><description>This is a node</description></node>`. In this case, `<description>` node does not have a value, but instead has a child of type [link node_pcdata] with value `"This is a node"`. pugixml provides several helper functions to parse such data:
-
-    const char_t* xml_node::child_value() const;
-    const char_t* xml_node::child_value(const char_t* name) const;
-    xml_text xml_node::text() const;
-
-`child_value()` returns the value of the first child with type [link node_pcdata] or [link node_cdata]; `child_value(name)` is a simple wrapper for `child(name).child_value()`. For the above example, calling `node.child_value("description")` and `description.child_value()` will both produce string `"This is a node"`. If there is no child with relevant type, or if the handle is null, `child_value` functions return empty string.
-
-`text()` returns a special object that can be used for working with PCDATA contents in more complex cases than just retrieving the value; it is described in [sref manual.access.text] sections.
-
-There is an example of using some of these functions [link code_traverse_base_data at the end of the next section].
-
-[endsect] [/nodedata]
-
-[section:attrdata Getting attribute data]
-
-[#xml_attribute::name][#xml_attribute::value]
-All attributes have name and value, both of which are strings (value may be empty). There are two corresponding accessors, like for `xml_node`:
-
-    const char_t* xml_attribute::name() const;
-    const char_t* xml_attribute::value() const;
-
-In case the attribute handle is null, both functions return empty strings - they never return null pointers.
-
-[#xml_attribute::as_string]
-If you need a non-empty string if the attribute handle is null (for example, you need to get the option value from XML attribute, but if it is not specified, you need it to default to `"sorted"` instead of `""`), you can use `as_string` accessor:
-
-    const char_t* xml_attribute::as_string(const char_t* def = "") const;
-
-It returns `def` argument if the attribute handle is null. If you do not specify the argument, the function is equivalent to `value()`.
-
-[#xml_attribute::as_int][#xml_attribute::as_uint][#xml_attribute::as_double][#xml_attribute::as_float][#xml_attribute::as_bool][#xml_attribute::as_llong][#xml_attribute::as_ullong]
-In many cases attribute values have types that are not strings - i.e. an attribute may always contain values that should be treated as integers, despite the fact that they are represented as strings in XML. pugixml provides several accessors that convert attribute value to some other type:
-
-    int xml_attribute::as_int(int def = 0) const;
-    unsigned int xml_attribute::as_uint(unsigned int def = 0) const;
-    double xml_attribute::as_double(double def = 0) const;
-    float xml_attribute::as_float(float def = 0) const;
-    bool xml_attribute::as_bool(bool def = false) const;
-    long long xml_attribute::as_llong(long long def = 0) const;
-    unsigned long long xml_attribute::as_ullong(unsigned long long def = 0) const;
-
-`as_int`, `as_uint`, `as_llong`, `as_ullong`, `as_double` and `as_float` convert attribute values to numbers. If attribute handle is null or attribute value is empty, `def` argument is returned (which is 0 by default). Otherwise, all leading whitespace characters are truncated, and the remaining string is parsed as an integer number in either decimal or hexadecimal form (applicable to `as_int`, `as_uint`, `as_llong` and `as_ullong`; hexadecimal format is used if the number has `0x` or `0X` prefix) or as a floating point number in either decimal or scientific form (`as_double` or `as_float`). Any extra characters are silently discarded, i.e. `as_int` will return `1` for string `"1abc"`.
-
-In case the input string contains a number that is out of the target numeric range, the result is undefined.
-
-[caution Number conversion functions depend on current C locale as set with `setlocale`, so may return unexpected results if the locale is different from `"C"`.]
-
-`as_bool` converts attribute value to boolean as follows: if attribute handle is null, `def` argument is returned (which is `false` by default). If attribute value is empty, `false` is returned. Otherwise, `true` is returned if the first character is one of `'1', 't', 'T', 'y', 'Y'`. This means that strings like `"true"` and `"yes"` are recognized as `true`, while strings like `"false"` and `"no"` are recognized as `false`. For more complex matching you'll have to write your own function.
-
-[note `as_llong` and `as_ullong` are only available if your platform has reliable support for the `long long` type, including string conversions.]
-
-[#code_traverse_base_data]

-[section:contents Contents-based traversal functions]
-
-[#xml_node::child][#xml_node::attribute][#xml_node::next_sibling_name][#xml_node::previous_sibling_name]
-Since a lot of document traversal consists of finding the node/attribute with the correct name, there are special functions for that purpose:
-
-    xml_node xml_node::child(const char_t* name) const;
-    xml_attribute xml_node::attribute(const char_t* name) const;
-    xml_node xml_node::next_sibling(const char_t* name) const;
-    xml_node xml_node::previous_sibling(const char_t* name) const;
-
-`child` and `attribute` return the first child/attribute with the specified name; `next_sibling` and `previous_sibling` return the first sibling in the corresponding direction with the specified name. All string comparisons are case-sensitive. In case the node handle is null or there is no node\/attribute with the specified name, null handle is returned.
-
-`child` and `next_sibling` functions can be used together to loop through all child nodes with the desired name like this:
-
-    for (pugi::xml_node tool = tools.child("Tool"); tool; tool = tool.next_sibling("Tool"))
-
-[#xml_node::find_child_by_attribute]
-Occasionally the needed node is specified not by the unique name but instead by the value of some attribute; for example, it is common to have node collections with each node having a unique id: `<group><item id="1"/> <item id="2"/></group>`. There are two functions for finding child nodes based on the attribute values:
-
-    xml_node xml_node::find_child_by_attribute(const char_t* name, const char_t* attr_name, const char_t* attr_value) const;
-    xml_node xml_node::find_child_by_attribute(const char_t* attr_name, const char_t* attr_value) const;
-
-The three-argument function returns the first child node with the specified name which has an attribute with the specified name/value; the two-argument function skips the name test for the node, which can be useful for searching in heterogeneous collections. If the node handle is null or if no node is found, null handle is returned. All string comparisons are case-sensitive.
-
-In all of the above functions, all arguments have to be valid strings; passing null pointers results in undefined behavior.
-
-This is an example of using these functions ([@samples/traverse_base.cpp]):

-[section:rangefor Range-based for-loop support]
-
-[#xml_node::children][#xml_node::attributes]
-If your C++ compiler supports range-based for-loop (this is a C++11 feature, at the time of writing it's supported by Microsoft Visual Studio 11 Beta, GCC 4.6 and Clang 3.0), you can use it to enumerate nodes/attributes. Additional helpers are provided to support this; note that they are also compatible with [@http://www.boost.org/libs/foreach/ Boost Foreach], and possibly other pre-C++11 foreach facilities.
-
-    ``/implementation-defined type/`` xml_node::children() const;
-    ``/implementation-defined type/`` xml_node::children(const char_t* name) const;
-    ``/implementation-defined type/`` xml_node::attributes() const;
-
-`children` function allows you to enumerate all child nodes; `children` function with `name` argument allows you to enumerate all child nodes with a specific name; `attributes` function allows you to enumerate all attributes of the node. Note that you can also use node object itself in a range-based for construct, which is equivalent to using `children()`.
-

-[section:iterators Traversing node/attribute lists via iterators]
-
-[#xml_node_iterator][#xml_attribute_iterator][#xml_node::begin][#xml_node::end][#xml_node::attributes_begin][#xml_node::attributes_end]
-Child node lists and attribute lists are simply double-linked lists; while you can use `previous_sibling`/`next_sibling` and other such functions for iteration, pugixml additionally provides node and attribute iterators, so that you can treat nodes as containers of other nodes or attributes:
-
-    class xml_node_iterator;
-    class xml_attribute_iterator;
-    
-    typedef xml_node_iterator xml_node::iterator;
-    iterator xml_node::begin() const;
-    iterator xml_node::end() const;
-
-    typedef xml_attribute_iterator xml_node::attribute_iterator;
-    attribute_iterator xml_node::attributes_begin() const;
-    attribute_iterator xml_node::attributes_end() const;
-
-`begin` and `attributes_begin` return iterators that point to the first node\/attribute, respectively; `end` and `attributes_end` return past-the-end iterator for node\/attribute list, respectively - this iterator can't be dereferenced, but decrementing it results in an iterator pointing to the last element in the list (except for empty lists, where decrementing past-the-end iterator results in undefined behavior). Past-the-end iterator is commonly used as a termination value for iteration loops (see sample below). If you want to get an iterator that points to an existing handle, you can construct the iterator with the handle as a single constructor argument, like so: `xml_node_iterator(node)`. For `xml_attribute_iterator`, you'll have to provide both an attribute and its parent node.
-
-`begin` and `end` return equal iterators if called on null node; such iterators can't be dereferenced. `attributes_begin` and `attributes_end` behave the same way. For correct iterator usage this means that child node\/attribute collections of null nodes appear to be empty.
-
-Both types of iterators have bidirectional iterator semantics (i.e. they can be incremented and decremented, but efficient random access is not supported) and support all usual iterator operations - comparison, dereference, etc. The iterators are invalidated if the node\/attribute objects they're pointing to are removed from the tree; adding nodes\/attributes does not invalidate any iterators.
-
-Here is an example of using iterators for document traversal ([@samples/traverse_iter.cpp]):
-
-[import samples/traverse_iter.cpp]
-[code_traverse_iter]
-
-[caution Node and attribute iterators are somewhere in the middle between const and non-const iterators. While dereference operation yields a non-constant reference to the object, so that you can use it for tree modification operations, modifying this reference by assignment - i.e. passing iterators to a function like `std::sort` - will not give expected results, as assignment modifies local handle that's stored in the iterator.]
-
-[endsect] [/iterators]
-
-[section:walker Recursive traversal with xml_tree_walker]
-
-[#xml_tree_walker]
-The methods described above allow traversal of immediate children of some node; if you want to do a deep tree traversal, you'll have to do it via a recursive function or some equivalent method. However, pugixml provides a helper for depth-first traversal of a subtree. In order to use it, you have to implement `xml_tree_walker` interface and to call `traverse` function:
-
-    class xml_tree_walker
-    {
-    public:
-        virtual bool begin(xml_node& node);
-        virtual bool for_each(xml_node& node) = 0;
-        virtual bool end(xml_node& node);
-
-        int depth() const;
-    };
-
-    bool xml_node::traverse(xml_tree_walker& walker);
-
-[#xml_tree_walker::begin][#xml_tree_walker::for_each][#xml_tree_walker::end][#xml_node::traverse]
-The traversal is launched by calling `traverse` function on traversal root and proceeds as follows:
-
-* First, `begin` function is called with traversal root as its argument.
-* Then, `for_each` function is called for all nodes in the traversal subtree in depth first order, excluding the traversal root. Node is passed as an argument.
-* Finally, `end` function is called with traversal root as its argument.
-
-If `begin`, `end` or any of the `for_each` calls return `false`, the traversal is terminated and `false` is returned as the traversal result; otherwise, the traversal results in `true`. Note that you don't have to override `begin` or `end` functions; their default implementations return `true`.
-
-[#xml_tree_walker::depth]
-You can get the node's depth relative to the traversal root at any point by calling `depth` function. It returns `-1` if called from `begin`\/`end`, and returns 0-based depth if called from `for_each` - depth is 0 for all children of the traversal root, 1 for all grandchildren and so on.
-
-This is an example of traversing tree hierarchy with xml_tree_walker ([@samples/traverse_walker.cpp]):

-[section:predicate Searching for nodes/attributes with predicates]
-
-[#xml_node::find_attribute][#xml_node::find_child][#xml_node::find_node]
-While there are existing functions for getting a node/attribute with known contents, they are often not sufficient for simple queries. As an alternative for manual iteration through nodes/attributes until the needed one is found, you can make a predicate and call one of `find_` functions:
-
-    template <typename Predicate> xml_attribute xml_node::find_attribute(Predicate pred) const;
-    template <typename Predicate> xml_node xml_node::find_child(Predicate pred) const;
-    template <typename Predicate> xml_node xml_node::find_node(Predicate pred) const;
-
-The predicate should be either a plain function or a function object which accepts one argument of type `xml_attribute` (for `find_attribute`) or `xml_node` (for `find_child` and `find_node`), and returns `bool`. The predicate is never called with null handle as an argument.
-
-`find_attribute` function iterates through all attributes of the specified node, and returns the first attribute for which the predicate returned `true`. If the predicate returned `false` for all attributes or if there were no attributes (including the case where the node is null), null attribute is returned.
-
-`find_child` function iterates through all child nodes of the specified node, and returns the first node for which the predicate returned `true`. If the predicate returned `false` for all nodes or if there were no child nodes (including the case where the node is null), null node is returned.
-
-`find_node` function performs a depth-first traversal through the subtree of the specified node (excluding the node itself), and returns the first node for which the predicate returned `true`. If the predicate returned `false` for all nodes or if subtree was empty, null node is returned.
-
-This is an example of using predicate-based functions ([@samples/traverse_predicate.cpp]):

-[section:text Working with text contents]
-
-[#xml_text]
-It is common to store data as text contents of some node - i.e. `<node><description>This is a node</description></node>`. In this case, `<description>` node does not have a value, but instead has a child of type [link node_pcdata] with value `"This is a node"`. pugixml provides a special class, `xml_text`, to work with such data. Working with text objects to modify data is described in [link manual.modify.text the documentation for modifying document data]; this section describes the access interface of `xml_text`.
-
-[#xml_node::text]
-You can get the text object from a node by using `text()` method:
-    
-    xml_text xml_node::text() const;
-
-If the node has a type `node_pcdata` or `node_cdata`, then the node itself is used to return data; otherwise, a first child node of type `node_pcdata` or `node_cdata` is used.
-
-[#xml_text::empty]
-[#xml_text::unspecified_bool_type]
-You can check if the text object is bound to a valid PCDATA/CDATA node by using it as a boolean value, i.e. `if (text) { ... }` or `if (!text) { ... }`. Alternatively you can check it by using the `empty()` method:
-
-    bool xml_text::empty() const;
-
-[#xml_text::get]
-Given a text object, you can get the contents (i.e. the value of PCDATA/CDATA node) by using the following function:
-
-    const char_t* xml_text::get() const;
-
-In case text object is empty, the function returns an empty string - it never returns a null pointer.
-
-[#xml_text::as_string][#xml_text::as_int][#xml_text::as_uint][#xml_text::as_double][#xml_text::as_float][#xml_text::as_bool][#xml_text::as_llong][#xml_text::as_ullong]
-If you need a non-empty string if the text object is empty, or if the text contents is actually a number or a boolean that is stored as a string, you can use the following accessors:
-
-    const char_t* xml_text::as_string(const char_t* def = "") const;
-    int xml_text::as_int(int def = 0) const;
-    unsigned int xml_text::as_uint(unsigned int def = 0) const;
-    double xml_text::as_double(double def = 0) const;
-    float xml_text::as_float(float def = 0) const;
-    bool xml_text::as_bool(bool def = false) const;
-    long long xml_text::as_llong(long long def = 0) const;
-    unsigned long long xml_text::as_ullong(unsigned long long def = 0) const;
-
-All of the above functions have the same semantics as similar `xml_attribute` members: they return the default argument if the text object is empty, they convert the text contents to a target type using the same rules and restrictions. You can [link xml_attribute::as_int refer to documentation for the attribute functions] for details.
-
-[#xml_text::data]
-`xml_text` is essentially a helper class that operates on `xml_node` values. It is bound to a node of type [link node_pcdata] or [link node_cdata]. You can use the following function to retrieve this node:
-
-    xml_node xml_text::data() const;
-
-Essentially, assuming `text` is an `xml_text` object, calling `text.get()` is equivalent to calling `text.data().value()`.
-
-This is an example of using `xml_text` object ([@samples/text.cpp]):

-[import samples/text.cpp]

-
-[section:misc Miscellaneous functions]
-
-[#xml_node::root]
-If you need to get the document root of some node, you can use the following function:
-
-    xml_node xml_node::root() const;
-
-This function returns the node with type [link node_document], which is the root node of the document the node belongs to (unless the node is null, in which case null node is returned).
-
-[#xml_node::path]
-[#xml_node::first_element_by_path]
-While pugixml supports complex XPath expressions, sometimes a simple path handling facility is needed. There are two functions, for getting node path and for converting path to a node:
-
-    string_t xml_node::path(char_t delimiter = '/') const;
-    xml_node xml_node::first_element_by_path(const char_t* path, char_t delimiter = '/') const;
-
-Node paths consist of node names, separated with a delimiter (which is `/` by default); also paths can contain self (`.`) and parent (`..`) pseudo-names, so that this is a valid path: `"../../foo/./bar"`. `path` returns the path to the node from the document root, `first_element_by_path` looks for a node represented by a given path; a path can be an absolute one (absolute paths start with the delimiter), in which case the rest of the path is treated as document root relative, and relative to the given node. For example, in the following document: `<a><b><c/></b></a>`, node `<c/>` has path `"a/b/c"`; calling `first_element_by_path` for document with path `"a/b"` results in node `<b/>`; calling `first_element_by_path` for node `<a/>` with path `"../a/./b/../."` results in node `<a/>`; calling `first_element_by_path` with path `"/a"` results in node `<a/>` for any node.
-
-In case path component is ambiguous (if there are two nodes with given name), the first one is selected; paths are not guaranteed to uniquely identify nodes in a document. If any component of a path is not found, the result of `first_element_by_path` is null node; also `first_element_by_path` returns null node for null nodes, in which case the path does not matter. `path` returns an empty string for null nodes. 
-
-[note `path` function returns the result as STL string, and thus is not available if [link PUGIXML_NO_STL] is defined.]
-
-[#xml_node::offset_debug]
-pugixml does not record row/column information for nodes upon parsing for efficiency reasons. However, if the node has not changed in a significant way since parsing (the name/value are not changed, and the node itself is the original one, i.e. it was not deleted from the tree and re-added later), it is possible to get the offset from the beginning of XML buffer:
-

-
-If the offset is not available (this happens if the node is null, was not originally parsed from a stream, or has changed in a significant way), the function returns -1. Otherwise it returns the offset to node's data from the beginning of XML buffer in [link char_t pugi::char_t] units. For more information on parsing offsets, see [link xml_parse_result::offset parsing error handling documentation].

-[section:modify Modifying document data]
-
-The document in pugixml is fully mutable: you can completely change the document structure and modify the data of nodes/attributes. This section provides documentation for the relevant functions. All functions take care of memory management and structural integrity themselves, so they always result in structurally valid tree - however, it is possible to create an invalid XML tree (for example, by adding two attributes with the same name or by setting attribute/node name to empty/invalid string). Tree modification is optimized for performance and for memory consumption, so if you have enough memory you can create documents from scratch with pugixml and later save them to file/stream instead of relying on error-prone manual text writing and without too much overhead.
-
-All member functions that change node/attribute data or structure are non-constant and thus can not be called on constant handles. However, you can easily convert constant handle to non-constant one by simple assignment: `void foo(const pugi::xml_node& n) { pugi::xml_node nc = n; }`, so const-correctness here mainly provides additional documentation.

-
-[#xml_node::set_name][#xml_node::set_value]
-As discussed before, nodes can have name and value, both of which are strings. Depending on node type, name or value may be absent. [link node_document] nodes do not have a name or value, [link node_element] and [link node_declaration] nodes always have a name but never have a value, [link node_pcdata], [link node_cdata], [link node_comment] and [link node_doctype] nodes never have a name but always have a value (it may be empty though), [link node_pi] nodes always have a name and a value (again, value may be empty). In order to set node's name or value, you can use the following functions:
-
-    bool xml_node::set_name(const char_t* rhs);
-    bool xml_node::set_value(const char_t* rhs);
-
-Both functions try to set the name\/value to the specified string, and return the operation result. The operation fails if the node can not have name or value (for instance, when trying to call `set_name` on a [link node_pcdata] node), if the node handle is null, or if there is insufficient memory to handle the request. The provided string is copied into document managed memory and can be destroyed after the function returns (for example, you can safely pass stack-allocated buffers to these functions). The name/value content is not verified, so take care to use only valid XML names, or the document may become malformed.
-
-There is no equivalent of [link xml_node::child_value child_value] function for modifying text children of the node.

-[section:attrdata Setting attribute data]
-
-[#xml_attribute::set_name][#xml_attribute::set_value]
-All attributes have name and value, both of which are strings (value may be empty). You can set them with the following functions:
-
-    bool xml_attribute::set_name(const char_t* rhs);
-    bool xml_attribute::set_value(const char_t* rhs);
-
-Both functions try to set the name\/value to the specified string, and return the operation result. The operation fails if the attribute handle is null, or if there is insufficient memory to handle the request. The provided string is copied into document managed memory and can be destroyed after the function returns (for example, you can safely pass stack-allocated buffers to these functions). The name/value content is not verified, so take care to use only valid XML names, or the document may become malformed.
-
-In addition to string functions, several functions are provided for handling attributes with numbers and booleans as values:
-
-    bool xml_attribute::set_value(int rhs);
-    bool xml_attribute::set_value(unsigned int rhs);
-    bool xml_attribute::set_value(double rhs);
-    bool xml_attribute::set_value(float rhs);
-    bool xml_attribute::set_value(bool rhs);
-    bool xml_attribute::set_value(long long rhs);
-    bool xml_attribute::set_value(unsigned long long rhs);
-    
-The above functions convert the argument to string and then call the base `set_value` function. Integers are converted to a decimal form, floating-point numbers are converted to either decimal or scientific form, depending on the number magnitude, boolean values are converted to either `"true"` or `"false"`.
-
-[caution Number conversion functions depend on current C locale as set with `setlocale`, so may generate unexpected results if the locale is different from `"C"`.]
-
-[note `set_value` overloads with `long long` type are only available if your platform has reliable support for the type, including string conversions.]
-
-[#xml_attribute::assign]
-
-For convenience, all `set_value` functions have the corresponding assignment operators:
-
-    xml_attribute& xml_attribute::operator=(const char_t* rhs);
-    xml_attribute& xml_attribute::operator=(int rhs);
-    xml_attribute& xml_attribute::operator=(unsigned int rhs);
-    xml_attribute& xml_attribute::operator=(double rhs);
-    xml_attribute& xml_attribute::operator=(float rhs);
-    xml_attribute& xml_attribute::operator=(bool rhs);
-    xml_attribute& xml_attribute::operator=(long long rhs);
-    xml_attribute& xml_attribute::operator=(unsigned long long rhs);
-
-These operators simply call the right `set_value` function and return the attribute they're called on; the return value of `set_value` is ignored, so errors are ignored.

-Nodes and attributes do not exist without a document tree, so you can't create them without adding them to some document. A node or attribute can be created at the end of node/attribute list or before\/after some other node:
-
-    xml_attribute xml_node::append_attribute(const char_t* name);
-    xml_attribute xml_node::prepend_attribute(const char_t* name);
-    xml_attribute xml_node::insert_attribute_after(const char_t* name, const xml_attribute& attr);
-    xml_attribute xml_node::insert_attribute_before(const char_t* name, const xml_attribute& attr);
-
-    xml_node xml_node::append_child(xml_node_type type = node_element);
-    xml_node xml_node::prepend_child(xml_node_type type = node_element);
-    xml_node xml_node::insert_child_after(xml_node_type type, const xml_node& node);
-    xml_node xml_node::insert_child_before(xml_node_type type, const xml_node& node);
-
-    xml_node xml_node::append_child(const char_t* name);
-    xml_node xml_node::prepend_child(const char_t* name);
-    xml_node xml_node::insert_child_after(const char_t* name, const xml_node& node);
-    xml_node xml_node::insert_child_before(const char_t* name, const xml_node& node);
-
-`append_attribute` and `append_child` create a new node\/attribute at the end of the corresponding list of the node the method is called on; `prepend_attribute` and `prepend_child` create a new node\/attribute at the beginning of the list; `insert_attribute_after`, `insert_attribute_before`, `insert_child_after` and `insert_attribute_before` add the node\/attribute before or after the specified node\/attribute.
-
-Attribute functions create an attribute with the specified name; you can specify the empty name and change the name later if you want to. Node functions with the `type` argument create the node with the specified type; since node type can't be changed, you have to know the desired type beforehand. Also note that not all types can be added as children; see below for clarification. Node functions with the `name` argument create the element node ([link node_element]) with the specified name.
-
-All functions return the handle to the created object on success, and null handle on failure. There are several reasons for failure:
-
-* Adding fails if the target node is null;
-* Only [link node_element] nodes can contain attributes, so attribute adding fails if node is not an element;
-* Only [link node_document] and [link node_element] nodes can contain children, so child node adding fails if the target node is not an element or a document;
-* [link node_document] and [link node_null] nodes can not be inserted as children, so passing [link node_document] or [link node_null] value as `type` results in operation failure;
-* [link node_declaration] nodes can only be added as children of the document node; attempt to insert declaration node as a child of an element node fails;
-* Adding node/attribute results in memory allocation, which may fail;
-* Insertion functions fail if the specified node or attribute is null or is not in the target node's children/attribute list.
-
-Even if the operation fails, the document remains in consistent state, but the requested node/attribute is not added.
-
-[caution attribute() and child() functions do not add attributes or nodes to the tree, so code like `node.attribute("id") = 123;` will not do anything if `node` does not have an attribute with name `"id"`. Make sure you're operating with existing attributes/nodes by adding them if necessary.]

-[section:remove Removing nodes/attributes]
-
-[#xml_node::remove_attribute][#xml_node::remove_child]
-If you do not want your document to contain some node or attribute, you can remove it with one of the following functions:
-
-    bool xml_node::remove_attribute(const xml_attribute& a);
-    bool xml_node::remove_child(const xml_node& n);
-
-`remove_attribute` removes the attribute from the attribute list of the node, and returns the operation result. `remove_child` removes the child node with the entire subtree (including all descendant nodes and attributes) from the document, and returns the operation result. Removing fails if one of the following is true:
-
-* The node the function is called on is null;
-* The attribute\/node to be removed is null;
-* The attribute\/node to be removed is not in the node's attribute\/child list.
-
-Removing the attribute or node invalidates all handles to the same underlying object, and also invalidates all iterators pointing to the same object. Removing node also invalidates all past-the-end iterators to its attribute or child node list. Be careful to ensure that all such handles and iterators either do not exist or are not used after the attribute\/node is removed.
-
-If you want to remove the attribute or child node by its name, two additional helper functions are available:
-
-    bool xml_node::remove_attribute(const char_t* name);
-    bool xml_node::remove_child(const char_t* name);
-
-These functions look for the first attribute or child with the specified name, and then remove it, returning the result. If there is no attribute or child with such name, the function returns `false`; if there are two nodes with the given name, only the first node is deleted. If you want to delete all nodes with the specified name, you can use code like this: `while (node.remove_child("tool")) ;`.

-[section:text Working with text contents]
-
-pugixml provides a special class, `xml_text`, to work with text contents stored as a value of some node, i.e. `<node><description>This is a node</description></node>`. Working with text objects to retrieve data is described in [link manual.access.text the documentation for accessing document data]; this section describes the modification interface of `xml_text`.
-
-[#xml_text::set]
-Once you have an `xml_text` object, you can set the text contents using the following function:
-
-    bool xml_text::set(const char_t* rhs);
-
-This function tries to set the contents to the specified string, and returns the operation result. The operation fails if the text object was retrieved from a node that can not have a value and is not an element node (i.e. it is a [link node_declaration] node), if the text object is empty, or if there is insufficient memory to handle the request. The provided string is copied into document managed memory and can be destroyed after the function returns (for example, you can safely pass stack-allocated buffers to this function). Note that if the text object was retrieved from an element node, this function creates the PCDATA child node if necessary (i.e. if the element node does not have a PCDATA/CDATA child already).
-
-[#xml_text::set_value]
-In addition to a string function, several functions are provided for handling text with numbers and booleans as contents:
-
-    bool xml_text::set(int rhs);
-    bool xml_text::set(unsigned int rhs);
-    bool xml_text::set(double rhs);
-    bool xml_text::set(float rhs);
-    bool xml_text::set(bool rhs);
-    bool xml_text::set(long long rhs);
-    bool xml_text::set(unsigned long long rhs);
-    
-The above functions convert the argument to string and then call the base `set` function. These functions have the same semantics as similar `xml_attribute` functions. You can [link xml_attribute::set_value refer to documentation for the attribute functions] for details.
-
-[#xml_text::assign]
-
-For convenience, all `set` functions have the corresponding assignment operators:
-
-    xml_text& xml_text::operator=(const char_t* rhs);
-    xml_text& xml_text::operator=(int rhs);
-    xml_text& xml_text::operator=(unsigned int rhs);
-    xml_text& xml_text::operator=(double rhs);
-    xml_text& xml_text::operator=(float rhs);
-    xml_text& xml_text::operator=(bool rhs);
-    xml_text& xml_text::operator=(long long rhs);
-    xml_text& xml_text::operator=(unsigned long long rhs);
-
-These operators simply call the right `set` function and return the attribute they're called on; the return value of `set` is ignored, so errors are ignored.

-[section:clone Cloning nodes/attributes]
-
-[#xml_node::prepend_copy][#xml_node::append_copy][#xml_node::insert_copy_after][#xml_node::insert_copy_before]
-With the help of previously described functions, it is possible to create trees with any contents and structure, including cloning the existing data. However since this is an often needed operation, pugixml provides built-in node/attribute cloning facilities. Since nodes and attributes do not exist without a document tree, you can't create a standalone copy - you have to immediately insert it somewhere in the tree. For this, you can use one of the following functions:
-
-    xml_attribute xml_node::append_copy(const xml_attribute& proto);
-    xml_attribute xml_node::prepend_copy(const xml_attribute& proto);
-    xml_attribute xml_node::insert_copy_after(const xml_attribute& proto, const xml_attribute& attr);
-    xml_attribute xml_node::insert_copy_before(const xml_attribute& proto, const xml_attribute& attr);
-
-    xml_node xml_node::append_copy(const xml_node& proto);
-    xml_node xml_node::prepend_copy(const xml_node& proto);
-    xml_node xml_node::insert_copy_after(const xml_node& proto, const xml_node& node);
-    xml_node xml_node::insert_copy_before(const xml_node& proto, const xml_node& node);
-
-These functions mirror the structure of `append_child`, `prepend_child`, `insert_child_before` and related functions - they take the handle to the prototype object, which is to be cloned, insert a new attribute\/node at the appropriate place, and then copy the attribute data or the whole node subtree to the new object. The functions return the handle to the resulting duplicate object, or null handle on failure.
-
-The attribute is copied along with the name and value; the node is copied along with its type, name and value; additionally attribute list and all children are recursively cloned, resulting in the deep subtree clone. The prototype object can be a part of the same document, or a part of any other document.
-
-The failure conditions resemble those of `append_child`, `insert_child_before` and related functions, [link xml_node::append_child consult their documentation for more information]. There are additional caveats specific to cloning functions:
-
-* Cloning null handles results in operation failure;
-* Node cloning starts with insertion of the node of the same type as that of the prototype; for this reason, cloning functions can not be directly used to clone entire documents, since [link node_document] is not a valid insertion type. The example below provides a workaround.
-* It is possible to copy a subtree as a child of some node inside this subtree, i.e. `node.append_copy(node.parent().parent());`. This is a valid operation, and it results in a clone of the subtree in the state before cloning started, i.e. no infinite recursion takes place.
-
-This is an example with one possible implementation of include tags in XML ([@samples/include.cpp]). It illustrates node cloning and usage of other document modification functions:

-
-[section:move Moving nodes]
-
-[#xml_node::prepend_move][#xml_node::append_move][#xml_node::insert_move_after][#xml_node::insert_move_before]
-Sometimes instead of cloning a node you need to move an existing node to a different position in a tree. This can be accomplished by copying the node and removing the original; however, this is expensive since it results in a lot of extra operations. For moving nodes within the same document tree, you can use of the following functions instead:
-
-    xml_node xml_node::append_move(const xml_node& moved);
-    xml_node xml_node::prepend_move(const xml_node& moved);
-    xml_node xml_node::insert_move_after(const xml_node& moved, const xml_node& node);
-    xml_node xml_node::insert_move_before(const xml_node& moved, const xml_node& node);
-
-These functions mirror the structure of `append_copy`, `prepend_copy`, `insert_copy_before` and `insert_copy_after` - they take the handle to the moved object and move it to the appropriate place with all attributes and/or child nodes. The functions return the handle to the resulting object (which is the same as the moved object), or null handle on failure.
-
-The failure conditions resemble those of `append_child`, `insert_child_before` and related functions, [link xml_node::append_child consult their documentation for more information]. There are additional caveats specific to moving functions:
-
-* Moving null handles results in operation failure;
-* Moving is only possible for nodes that belong to the same document; attempting to move nodes between documents will fail.
-* `insert_move_after` and `insert_move_before` functions fail if the moved node is the same as the `node` argument (this operation would be a no-op otherwise).
-* It is impossible to move a subtree to a child of some node inside this subtree, i.e. `node.append_move(node.parent().parent());` will fail.

-[section:fragments Assembling document from fragments]
-
-[#xml_node::append_buffer]
-pugixml provides several ways to assemble an XML document from other XML documents. Assuming there is a set of document fragments, represented as in-memory buffers, the implementation choices are as follows:
-
-* Use a temporary document to parse the data from a string, then clone the nodes to a destination node. For example:
-
-    bool append_fragment(pugi::xml_node target, const char* buffer, size_t size)
-    {
-        pugi::xml_document doc;
-        if (!doc.load_buffer(buffer, size)) return false;
-
-        for (pugi::xml_node child = doc.first_child(); child; child = child.next_sibling())
-            target.append_copy(child);
-    }
-
-* Cache the parsing step - instead of keeping in-memory buffers, keep document objects that already contain the parsed fragment:
-
-    bool append_fragment(pugi::xml_node target, const pugi::xml_document& cached_fragment)
-    {
-        for (pugi::xml_node child = cached_fragment.first_child(); child; child = child.next_sibling())
-            target.append_copy(child);
-    }
-
-* Use xml_node::append_buffer directly:
-
-    xml_parse_result xml_node::append_buffer(const void* contents, size_t size, unsigned int options = parse_default, xml_encoding encoding = encoding_auto);
-
-The first method is more convenient, but slower than the other two. The relative performance of `append_copy` and `append_buffer` depends on the buffer format - usually `append_buffer` is faster if the buffer is in native encoding (UTF-8 or wchar_t, depending on `PUGIXML_WCHAR_MODE`). At the same time it might be less efficient in terms of memory usage - the implementation makes a copy of the provided buffer, and the copy has the same lifetime as the document - the memory used by that copy will be reclaimed after the document is destroyed, but no sooner. Even deleting all nodes in the document, including the appended ones, won't reclaim the memory.
-
-`append_buffer` behaves in the same way as [link xml_document::load_buffer] - the input buffer is a byte buffer, with size in bytes; the buffer is not modified and can be freed after the function returns.
-
-[#status_append_invalid_root]
-Since `append_buffer` needs to append child nodes to the current node, it only works if the current node is either document or element node. Calling `append_buffer` on a node with any other type results in an error with `status_append_invalid_root` status.

-[section:saving Saving document]
-
-Often after creating a new document or loading the existing one and processing it, it is necessary to save the result back to file. Also it is occasionally useful to output the whole document or a subtree to some stream; use cases include debug printing, serialization via network or other text-oriented medium, etc. pugixml provides several functions to output any subtree of the document to a file, stream or another generic transport interface; these functions allow to customize the output format (see [sref manual.saving.options]), and also perform necessary encoding conversions (see [sref manual.saving.encoding]). This section documents the relevant functionality.
-
-Before writing to the destination the node/attribute data is properly formatted according to the node type; all special XML symbols, such as < and &, are properly escaped (unless [link format_no_escapes] flag is set). In order to guard against forgotten node/attribute names, empty node/attribute names are printed as `":anonymous"`. For well-formed output, make sure all node and attribute names are set to meaningful values.
-
-CDATA sections with values that contain `"]]>"` are split into several sections as follows: section with value `"pre]]>post"` is written as `<![CDATA[pre]]]]><![CDATA[>post]]>`. While this alters the structure of the document (if you load the document after saving it, there will be two CDATA sections instead of one), this is the only way to escape CDATA contents.
-
-[section:file Saving document to a file]
-
-[#xml_document::save_file]
-[#xml_document::save_file_wide]
-If you want to save the whole document to a file, you can use one of the following functions:
-
-    bool xml_document::save_file(const char* path, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto) const;
-    bool xml_document::save_file(const wchar_t* path, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto) const;
-
-These functions accept file path as its first argument, and also three optional arguments, which specify indentation and other output options (see [sref manual.saving.options]) and output data encoding (see [sref manual.saving.encoding]). The path has the target operating system format, so it can be a relative or absolute one, it should have the delimiters of the target system, it should have the exact case if the target file system is case-sensitive, etc.
-
-File path is passed to the system file opening function as is in case of the first function (which accepts `const char* path`); the second function either uses a special file opening function if it is provided by the runtime library or converts the path to UTF-8 and uses the system file opening function.
-
-[#xml_writer_file]
-`save_file` opens the target file for writing, outputs the requested header (by default a document declaration is output, unless the document already has one), and then saves the document contents. If the file could not be opened, the function returns `false`. Calling `save_file` is equivalent to creating an `xml_writer_file` object with `FILE*` handle as the only constructor argument and then calling `save`; see [sref manual.saving.writer] for writer interface details.
-
-This is a simple example of saving XML document to file ([@samples/save_file.cpp]):

-[section:stream Saving document to C++ IOstreams]
-
-[#xml_document::save_stream]
-To enhance interoperability pugixml provides functions for saving document to any object which implements C++ `std::ostream` interface. This allows you to save documents to any standard C++ stream (i.e. file stream) or any third-party compliant implementation (i.e. Boost Iostreams). Most notably, this allows for easy debug output, since you can use `std::cout` stream as saving target. There are two functions, one works with narrow character streams, another handles wide character ones:
-
-    void xml_document::save(std::ostream& stream, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto) const;
-    void xml_document::save(std::wostream& stream, const char_t* indent = "\t", unsigned int flags = format_default) const;
-
-`save` with `std::ostream` argument saves the document to the stream in the same way as `save_file` (i.e. with requested header and with encoding conversions). On the other hand, `save` with `std::wstream` argument saves the document to the wide stream with [link encoding_wchar] encoding.  Because of this, using `save` with wide character streams requires careful (usually platform-specific) stream setup (i.e. using the `imbue` function). Generally use of wide streams is discouraged, however it provides you with the ability to save documents to non-Unicode encodings, i.e. you can save Shift-JIS encoded data if you set the correct locale.
-
-[#xml_writer_stream]
-Calling `save` with stream target is equivalent to creating an `xml_writer_stream` object with stream as the only constructor argument and then calling `save`; see [sref manual.saving.writer] for writer interface details.
-
-This is a simple example of saving XML document to standard output ([@samples/save_stream.cpp]):
-
-[import samples/save_stream.cpp]
-[code_save_stream]
-
-[endsect] [/stream]
-
-[section:writer Saving document via writer interface]
-
-[#xml_document::save][#xml_writer][#xml_writer::write]
-All of the above saving functions are implemented in terms of writer interface. This is a simple interface with a single function, which is called several times during output process with chunks of document data as input:
-
-    class xml_writer
-    {
-    public:
-        virtual void write(const void* data, size_t size) = 0;
-    };
-
-    void xml_document::save(xml_writer& writer, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto) const;
-
-In order to output the document via some custom transport, for example sockets, you should create an object which implements `xml_writer` interface and pass it to `save` function. `xml_writer::write` function is called with a buffer as an input, where `data` points to buffer start, and `size` is equal to the buffer size in bytes. `write` implementation must write the buffer to the transport; it can not save the passed buffer pointer, as the buffer contents will change after `write` returns. The buffer contains the chunk of document data in the desired encoding.
-
-`write` function is called with relatively large blocks (size is usually several kilobytes, except for the last block that may be small), so there is often no need for additional buffering in the implementation.
-
-This is a simple example of custom writer for saving document data to STL string ([@samples/save_custom_writer.cpp]); read the sample code for more complex examples:
-
-[import samples/save_custom_writer.cpp]

-[section:subtree Saving a single subtree]
-
-[#xml_node::print][#xml_node::print_stream]
-While the previously described functions save the whole document to the destination, it is easy to save a single subtree. The following functions are provided:
-
-    void xml_node::print(std::ostream& os, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto, unsigned int depth = 0) const;
-    void xml_node::print(std::wostream& os, const char_t* indent = "\t", unsigned int flags = format_default, unsigned int depth = 0) const;
-    void xml_node::print(xml_writer& writer, const char_t* indent = "\t", unsigned int flags = format_default, xml_encoding encoding = encoding_auto, unsigned int depth = 0) const;
-
-These functions have the same arguments with the same meaning as the corresponding `xml_document::save` functions, and allow you to save the subtree to either a C++ IOstream or to any object that implements `xml_writer` interface.
-
-Saving a subtree differs from saving the whole document: the process behaves as if [link format_write_bom] is off, and [link format_no_declaration] is on, even if actual values of the flags are different. This means that BOM is not written to the destination, and document declaration is only written if it is the node itself or is one of node's children. Note that this also holds if you're saving a document; this example ([@samples/save_subtree.cpp]) illustrates the difference:
-
-[import samples/save_subtree.cpp]
-[code_save_subtree]
-
-[endsect] [/subtree]
-
-[section:options Output options]
-
-All saving functions accept the optional parameter `flags`. This is a bitmask that customizes the output format; you can select the way the document nodes are printed and select the needed additional information that is output before the document contents.
-
-[note You should use the usual bitwise arithmetics to manipulate the bitmask: to enable a flag, use `mask | flag`; to disable a flag, use `mask & ~flag`.]
-
-These flags control the resulting tree contents:
-
-* [anchor format_indent] determines if all nodes should be indented with the indentation string (this is an additional parameter for all saving functions, and is `"\t"` by default). If this flag is on, before every node the indentation string is output several times, where the amount of indentation depends on the node's depth relative to the output subtree. This flag has no effect if [link format_raw] is enabled. This flag is *on* by default.
-[lbr]
-
-* [anchor format_raw] switches between formatted and raw output. If this flag is on, the nodes are not indented in any way, and also no newlines that are not part of document text are printed. Raw mode can be used for serialization where the result is not intended to be read by humans; also it can be useful if the document was parsed with [link parse_ws_pcdata] flag, to preserve the original document formatting as much as possible. This flag is *off* by default.
-[lbr]
-
-* [anchor format_no_escapes] disables output escaping for attribute values and PCDATA contents. If this flag is off, special symbols (', &, <, >) and all non-printable characters (those with codepoint values less than 32) are converted to XML escape sequences (i.e. &amp;) during output. If this flag is on, no text processing is performed; therefore, output XML can be malformed if output contents contains invalid symbols (i.e. having a stray < in the PCDATA will make the output malformed). This flag is *off* by default.
-
-These flags control the additional output information:
-
-* [anchor format_no_declaration] disables default node declaration output. By default, if the document is saved via `save` or `save_file` function, and it does not have any document declaration, a default declaration is output before the document contents. Enabling this flag disables this declaration. This flag has no effect in `xml_node::print` functions: they never output the default declaration. This flag is *off* by default.
-[lbr]
-
-* [anchor format_write_bom] enables Byte Order Mark (BOM) output. By default, no BOM is output, so in case of non UTF-8 encodings the resulting document's encoding may not be recognized by some parsers and text editors, if they do not implement sophisticated encoding detection. Enabling this flag adds an encoding-specific BOM to the output. This flag has no effect in `xml_node::print` functions: they never output the BOM. This flag is *off* by default.
-
-* [anchor format_save_file_text] changes the file mode when using `save_file` function. By default, file is opened in binary mode, which means that the output file will
-contain platform-independent newline \\n (ASCII 10). If this flag is on, file is opened in text mode, which on some systems changes the newline format (i.e. on Windows you can use this flag to output XML documents with \\r\\n (ASCII 13 10) newlines. This flag is *off* by default.
-
-Additionally, there is one predefined option mask:
-
-* [anchor format_default] is the default set of flags, i.e. it has all options set to their default values. It sets formatted output with indentation, without BOM and with default node declaration, if necessary.
-
-This is an example that shows the outputs of different output options ([@samples/save_options.cpp]):

-[section:encoding Encodings]
-
-pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it's a strict subset of UTF-16) and handles all encoding conversions during output. The output encoding is set via the `encoding` parameter of saving functions, which is of type `xml_encoding`. The possible values for the encoding are documented in [sref manual.loading.encoding]; the only flag that has a different meaning is `encoding_auto`.
-
-While all other flags set the exact encoding, `encoding_auto` is meant for automatic encoding detection. The automatic detection does not make sense for output encoding, since there is usually nothing to infer the actual encoding from, so here `encoding_auto` means UTF-8 encoding, which is the most popular encoding for XML data storage. This is also the default value of output encoding; specify another value if you do not want UTF-8 encoded output.
-
-Also note that wide stream saving functions do not have `encoding` argument and always assume [link encoding_wchar] encoding.
-
-[note The current behavior for Unicode conversion is to skip all invalid UTF sequences during conversion. This behavior should not be relied upon; if your node/attribute names do not contain any valid UTF sequences, they may be output as if they are empty, which will result in malformed XML document.]
-
-[endsect] [/encoding]
-
-[section:declaration Customizing document declaration]
-
-When you are saving the document using `xml_document::save()` or `xml_document::save_file()`, a default XML document declaration is output, if `format_no_declaration` is not specified and if the document does not have a declaration node. However, the default declaration is not customizable. If you want to customize the declaration output, you need to create the declaration node yourself.
-
-[note By default the declaration node is not added to the document during parsing. If you just need to preserve the original declaration node, you have to add the flag [link parse_declaration] to the parsing flags; the resulting document will contain the original declaration node, which will be output during saving.]
-
-Declaration node is a node with type [link node_declaration]; it behaves like an element node in that it has attributes with values (but it does not have child nodes). Therefore setting custom version, encoding or standalone declaration involves adding attributes and setting attribute values.
-
-This is an example that shows how to create a custom declaration node ([@samples/save_declaration.cpp]):

-[section:xpath XPath]
-
-If the task at hand is to select a subset of document nodes that match some criteria, it is possible to code a function using the existing traversal functionality for any practical criteria. However, often either a data-driven approach is desirable, in case the criteria are not predefined and come from a file, or it is inconvenient to use traversal interfaces and a higher-level DSL is required. There is a standard language for XML processing, XPath, that can be useful for these cases. pugixml implements an almost complete subset of XPath 1.0. Because of differences in document object model and some performance implications, there are minor violations of the official specifications, which can be found in [sref manual.xpath.w3c]. The rest of this section describes the interface for XPath functionality. Please note that if you wish to learn to use XPath language, you have to look for other tutorials or manuals; for example, you can read [@http://www.w3schools.com/xpath/ W3Schools XPath tutorial], [@http://www.tizag.com/xmlTutorial/xpathtutorial.php XPath tutorial at tizag.com], and [@http://www.w3.org/TR/xpath/ the XPath 1.0 specification].
-
-[section:types XPath types]
-
-[#xpath_value_type][#xpath_type_number][#xpath_type_string][#xpath_type_boolean][#xpath_type_node_set][#xpath_type_none]
-Each XPath expression can have one of the following types: boolean, number, string or node set. Boolean type corresponds to `bool` type, number type corresponds to `double` type, string type corresponds to either `std::string` or `std::wstring`, depending on whether [link manual.dom.unicode wide character interface is enabled], and node set corresponds to [link xpath_node_set] type. There is an enumeration, `xpath_value_type`, which can take the values `xpath_type_boolean`, `xpath_type_number`, `xpath_type_string` or `xpath_type_node_set`, accordingly.
-
-[#xpath_node][#xpath_node::node][#xpath_node::attribute][#xpath_node::parent]
-Because an XPath node can be either a node or an attribute, there is a special type, `xpath_node`, which is a discriminated union of these types. A value of this type contains two node handles, one of `xml_node` type, and another one of `xml_attribute` type; at most one of them can be non-null. The accessors to get these handles are available:
-
-    xml_node xpath_node::node() const;
-    xml_attribute xpath_node::attribute() const;
-
-XPath nodes can be null, in which case both accessors return null handles.
-
-Note that as per XPath specification, each XPath node has a parent, which can be retrieved via this function:
-
-    xml_node xpath_node::parent() const;
-
-`parent` function returns the node's parent if the XPath node corresponds to `xml_node` handle (equivalent to `node().parent()`), or the node to which the attribute belongs to, if the XPath node corresponds to `xml_attribute` handle. For null nodes, `parent` returns null handle.
-
-[#xpath_node::unspecified_bool_type][#xpath_node::comparison]
-Like node and attribute handles, XPath node handles can be implicitly cast to boolean-like object to check if it is a null node, and also can be compared for equality with each other.
-
-[#xpath_node::ctor]
-You can also create XPath nodes with one of the three constructors: the default constructor, the constructor that takes node argument, and the constructor that takes attribute and node arguments (in which case the attribute must belong to the attribute list of the node). The constructor from `xml_node` is implicit, so you can usually pass `xml_node` to functions that expect `xpath_node`. Apart from that you usually don't need to create your own XPath node objects, since they are returned to you via selection functions.
-
-[#xpath_node_set]
-XPath expressions operate not on single nodes, but instead on node sets. A node set is a collection of nodes, which can be optionally ordered in either a forward document order or a reverse one. Document order is defined in XPath specification; an XPath node is before another node in document order if it appears before it in XML representation of the corresponding document.
-
-[#xpath_node_set::const_iterator][#xpath_node_set::begin][#xpath_node_set::end]
-Node sets are represented by `xpath_node_set` object, which has an interface that resembles one of sequential random-access containers. It has an iterator type along with usual begin/past-the-end iterator accessors:
-
-    typedef const xpath_node* xpath_node_set::const_iterator;
-    const_iterator xpath_node_set::begin() const;
-    const_iterator xpath_node_set::end() const;
-
-[#xpath_node_set::index][#xpath_node_set::size][#xpath_node_set::empty]
-And it also can be iterated via indices, just like `std::vector`:
-
-    const xpath_node& xpath_node_set::operator[](size_t index) const;
-    size_t xpath_node_set::size() const;
-    bool xpath_node_set::empty() const;
-
-All of the above operations have the same semantics as that of `std::vector`: the iterators are random-access, all of the above operations are constant time, and accessing the element at index that is greater or equal than the set size results in undefined behavior. You can use both iterator-based and index-based access for iteration, however the iterator-based one can be faster.
-
-[#xpath_node_set::type][#xpath_node_set::type_unsorted][#xpath_node_set::type_sorted][#xpath_node_set::type_sorted_reverse][#xpath_node_set::sort]
-The order of iteration depends on the order of nodes inside the set; the order can be queried via the following function:
-
-    enum xpath_node_set::type_t {type_unsorted, type_sorted, type_sorted_reverse};
-    type_t xpath_node_set::type() const;
-
-`type` function returns the current order of nodes; `type_sorted` means that the nodes are in forward document order, `type_sorted_reverse` means that the nodes are in reverse document order, and `type_unsorted` means that neither order is guaranteed (nodes can accidentally be in a sorted order even if `type()` returns `type_unsorted`). If you require a specific order of iteration, you can change it via `sort` function:
-
-    void xpath_node_set::sort(bool reverse = false);
-
-Calling `sort` sorts the nodes in either forward or reverse document order, depending on the argument; after this call `type()` will return `type_sorted` or `type_sorted_reverse`.
-
-[#xpath_node_set::first]
-Often the actual iteration is not needed; instead, only the first element in document order is required. For this, a special accessor is provided:
-
-    xpath_node xpath_node_set::first() const;
-
-This function returns the first node in forward document order from the set, or null node if the set is empty. Note that while the result of the node does not depend on the order of nodes in the set (i.e. on the result of `type()`), the complexity does - if the set is sorted, the complexity is constant, otherwise it is linear in the number of elements or worse.
-
-[#xpath_node_set::ctor]
-While in the majority of cases the node set is returned by XPath functions, sometimes there is a need to manually construct a node set. For such cases, a constructor is provided which takes an iterator range (`const_iterator` is a typedef for `const xpath_node*`), and an optional type:
-
-	xpath_node_set::xpath_node_set(const_iterator begin, const_iterator end, type_t type = type_unsorted);
-
-The constructor copies the specified range and sets the specified type. The objects in the range are not checked in any way; you'll have to ensure that the range contains no duplicates, and that the objects are sorted according to the `type` parameter. Otherwise XPath operations with this set may produce unexpected results.
-
-[endsect] [/types]
-
-[section:select Selecting nodes via XPath expression]
-
-[#xml_node::select_node][#xml_node::select_nodes]
-If you want to select nodes that match some XPath expression, you can do it with the following functions:
-
-    xpath_node xml_node::select_node(const char_t* query, xpath_variable_set* variables = 0) const;
-    xpath_node_set xml_node::select_nodes(const char_t* query, xpath_variable_set* variables = 0) const;
-
-`select_nodes` function compiles the expression and then executes it with the node as a context node, and returns the resulting node set. `select_node` returns only the first node in document order from the result, and is equivalent to calling `select_nodes(query).first()`. If the XPath expression does not match anything, or the node handle is null, `select_nodes` returns an empty set, and `select_node` returns null XPath node.
-
-If exception handling is not disabled, both functions throw [link xpath_exception] if the query can not be compiled or if it returns a value with type other than node set; see [sref manual.xpath.errors] for details.
-
-[#xml_node::select_node_precomp][#xml_node::select_nodes_precomp]
-While compiling expressions is fast, the compilation time can introduce a significant overhead if the same expression is used many times on small subtrees. If you're doing many similar queries, consider compiling them into query objects (see [sref manual.xpath.query] for further reference). Once you get a compiled query object, you can pass it to select functions instead of an expression string:
-
-    xpath_node xml_node::select_node(const xpath_query& query) const;
-    xpath_node_set xml_node::select_nodes(const xpath_query& query) const;
-
-If exception handling is not disabled, both functions throw [link xpath_exception] if the query returns a value with type other than node set.
-
-This is an example of selecting nodes using XPath expressions ([@samples/xpath_select.cpp]):
-
-[import samples/xpath_select.cpp]
-[code_xpath_select]
-
-[endsect] [/select]
-
-[section:query Using query objects]
-
-[#xpath_query]
-When you call `select_nodes` with an expression string as an argument, a query object is created behind the scenes. A query object represents a compiled XPath expression. Query objects can be needed in the following circumstances:
-
-* You can precompile expressions to query objects to save compilation time if it becomes an issue;
-* You can use query objects to evaluate XPath expressions which result in booleans, numbers or strings;
-* You can get the type of expression value via query object.
-
-Query objects correspond to `xpath_query` type. They are immutable and non-copyable: they are bound to the expression at creation time and can not be cloned. If you want to put query objects in a container, allocate them on heap via `new` operator and store pointers to `xpath_query` in the container.
-
-[#xpath_query::ctor]
-You can create a query object with the constructor that takes XPath expression as an argument:
-
-    explicit xpath_query::xpath_query(const char_t* query, xpath_variable_set* variables = 0);
-
-[#xpath_query::return_type]
-The expression is compiled and the compiled representation is stored in the new query object. If compilation fails, [link xpath_exception] is thrown if exception handling is not disabled (see [sref manual.xpath.errors] for details). After the query is created, you can query the type of the evaluation result using the following function:
-
-    xpath_value_type xpath_query::return_type() const;
-
-[#xpath_query::evaluate_boolean][#xpath_query::evaluate_number][#xpath_query::evaluate_string][#xpath_query::evaluate_node_set][#xpath_query::evaluate_node]
-You can evaluate the query using one of the following functions:
-
-    bool xpath_query::evaluate_boolean(const xpath_node& n) const;
-    double xpath_query::evaluate_number(const xpath_node& n) const;
-    string_t xpath_query::evaluate_string(const xpath_node& n) const;
-    xpath_node_set xpath_query::evaluate_node_set(const xpath_node& n) const;
-    xpath_node xpath_query::evaluate_node(const xpath_node& n) const;
-
-All functions take the context node as an argument, compute the expression and return the result, converted to the requested type. According to XPath specification, value of any type can be converted to boolean, number or string value, but no type other than node set can be converted to node set. Because of this, `evaluate_boolean`, `evaluate_number` and `evaluate_string` always return a result, but `evaluate_node_set` and `evaluate_node` result in an error if the return type is not node set (see [sref manual.xpath.errors]).
-
-[note Calling `node.select_nodes("query")` is equivalent to calling `xpath_query("query").evaluate_node_set(node)`. Calling `node.select_node("query")` is equivalent to calling `xpath_query("query").evaluate_node(node)`.]
-
-[#xpath_query::evaluate_string_buffer]
-Note that `evaluate_string` function returns the STL string; as such, it's not available in [link PUGIXML_NO_STL] mode and also usually allocates memory. There is another string evaluation function:
-
-	size_t xpath_query::evaluate_string(char_t* buffer, size_t capacity, const xpath_node& n) const;
-
-This function evaluates the string, and then writes the result to `buffer` (but at most `capacity` characters); then it returns the full size of the result in characters, including the terminating zero. If `capacity` is not 0, the resulting buffer is always zero-terminated. You can use this function as follows: 
-
-* First call the function with `buffer = 0` and `capacity = 0`; then allocate the returned amount of characters, and call the function again, passing the allocated storage and the amount of characters;
-* First call the function with small buffer and buffer capacity; then, if the result is larger than the capacity, the output has been trimmed, so allocate a larger buffer and call the function again.
-
-This is an example of using query objects ([@samples/xpath_query.cpp]):
-
-[import samples/xpath_query.cpp]
-[code_xpath_query]
-
-[endsect] [/query]
-
-[section:variables Using variables]
-
-XPath queries may contain references to variables; this is useful if you want to use queries that depend on some dynamic parameter without manually preparing the complete query string, or if you want to reuse the same query object for similar queries.
-
-Variable references have the form '''<code><phrase role="identifier">$name</phrase></code>'''; in order to use them, you have to provide a variable set, which includes all variables present in the query with correct types. This set is passed to `xpath_query` constructor or to `select_nodes`/`select_node` functions:
-
-    explicit xpath_query::xpath_query(const char_t* query, xpath_variable_set* variables = 0);
-    xpath_node xml_node::select_node(const char_t* query, xpath_variable_set* variables = 0) const;
-    xpath_node_set xml_node::select_nodes(const char_t* query, xpath_variable_set* variables = 0) const;
-
-If you're using query objects, you can change the variable values before `evaluate`/`select` calls to change the query behavior.
-
-[note The variable set pointer is stored in the query object; you have to ensure that the lifetime of the set exceeds that of query object.]
-
-[#xpath_variable_set]
-Variable sets correspond to `xpath_variable_set` type, which is essentially a variable container.
-
-[#xpath_variable_set::add]
-You can add new variables with the following function:
-
-    xpath_variable* xpath_variable_set::add(const char_t* name, xpath_value_type type);
-
-The function tries to add a new variable with the specified name and type; if the variable with such name does not exist in the set, the function adds a new variable and returns the variable handle; if there is already a variable with the specified name, the function returns the variable handle if variable has the specified type. Otherwise the function returns null pointer; it also returns null pointer on allocation failure.
-
-New variables are assigned the default value which depends on the type: `0` for numbers, `false` for booleans, empty string for strings and empty set for node sets.
-
-[#xpath_variable_set::get]
-You can get the existing variables with the following functions:
-
-    xpath_variable* xpath_variable_set::get(const char_t* name);
-    const xpath_variable* xpath_variable_set::get(const char_t* name) const;
-
-The functions return the variable handle, or null pointer if the variable with the specified name is not found.
-
-[#xpath_variable_set::set]
-Additionally, there are the helper functions for setting the variable value by name; they try to add the variable with the corresponding type, if it does not exist, and to set the value. If the variable with the same name but with different type is already present, they return `false`; they also return `false` on allocation failure. Note that these functions do not perform any type conversions.
-
-    bool xpath_variable_set::set(const char_t* name, bool value);
-    bool xpath_variable_set::set(const char_t* name, double value);
-    bool xpath_variable_set::set(const char_t* name, const char_t* value);
-    bool xpath_variable_set::set(const char_t* name, const xpath_node_set& value);
-
-The variable values are copied to the internal variable storage, so you can modify or destroy them after the functions return.
-
-[#xpath_variable]
-If setting variables by name is not efficient enough, or if you have to inspect variable information or get variable values, you can use variable handles. A variable corresponds to the `xpath_variable` type, and a variable handle is simply a pointer to `xpath_variable`.
-
-[#xpath_variable::type][#xpath_variable::name]
-In order to get variable information, you can use one of the following functions:
-
-    const char_t* xpath_variable::name() const;
-    xpath_value_type xpath_variable::type() const;
-
-Note that each variable has a distinct type which is specified upon variable creation and can not be changed later.
-
-[#xpath_variable::get_boolean][#xpath_variable::get_number][#xpath_variable::get_string][#xpath_variable::get_node_set]
-In order to get variable value, you should use one of the following functions, depending on the variable type:
-
-    bool xpath_variable::get_boolean() const;
-    double xpath_variable::get_number() const;
-    const char_t* xpath_variable::get_string() const;
-    const xpath_node_set& xpath_variable::get_node_set() const;
-
-These functions return the value of the variable. Note that no type conversions are performed; if the type mismatch occurs, a dummy value is returned (`false` for booleans, `NaN` for numbers, empty string for strings and empty set for node sets).
-
-[#xpath_variable::set]
-In order to set variable value, you should use one of the following functions, depending on the variable type:
-
-    bool xpath_variable::set(bool value);
-    bool xpath_variable::set(double value);
-    bool xpath_variable::set(const char_t* value);
-    bool xpath_variable::set(const xpath_node_set& value);
-
-These functions modify the variable value. Note that no type conversions are performed; if the type mismatch occurs, the functions return `false`; they also return `false` on allocation failure. The variable values are copied to the internal variable storage, so you can modify or destroy them after the functions return.
-

-
-[section:errors Error handling]
-
-There are two different mechanisms for error handling in XPath implementation; the mechanism used depends on whether exception support is disabled (this is controlled with [link PUGIXML_NO_EXCEPTIONS] define).
-
-[#xpath_exception]
-[#xpath_exception::result]
-[#xpath_exception::what]
-By default, XPath functions throw `xpath_exception` object in case of errors; additionally, in the event any memory allocation fails, an `std::bad_alloc` exception is thrown. Also `xpath_exception` is thrown if the query is evaluated to a node set, but the return type is not node set. If the query constructor succeeds (i.e. no exception is thrown), the query object is valid. Otherwise you can get the error details via one of the following functions:
-
-    virtual const char* xpath_exception::what() const throw();
-    const xpath_parse_result& xpath_exception::result() const;
-
-[#xpath_query::unspecified_bool_type]
-[#xpath_query::result]
-If exceptions are disabled, then in the event of parsing failure the query is initialized to invalid state; you can test if the query object is valid by using it in a boolean expression: `if (query) { ... }`. Additionally, you can get parsing result via the result() accessor:
-
-    const xpath_parse_result& xpath_query::result() const;
-    
-Without exceptions, evaluating invalid query results in `false`, empty string, NaN or an empty node set, depending on the type; evaluating a query as a node set results in an empty node set if the return type is not node set.
-
-[#xpath_parse_result]
-The information about parsing result is returned via `xpath_parse_result` object. It contains parsing status and the offset of last successfully parsed character from the beginning of the source stream:
-
-    struct xpath_parse_result
-    {
-        const char* error;
-        ptrdiff_t offset;
-
-        operator bool() const;
-        const char* description() const;
-    };

-[#xpath_parse_result::error]
-Parsing result is represented as the error message; it is either a null pointer, in case there is no error, or the error message in the form of ASCII zero-terminated string.
-
-[#xpath_parse_result::description]
-`description()` member function can be used to get the error message; it never returns the null pointer, so you can safely use `description()` even if query parsing succeeded. Note that `description()` returns a `char` string even in `PUGIXML_WCHAR_MODE`; you'll have to call [link as_wide] to get the `wchar_t` string.
-
-[#xpath_parse_result::offset]
-In addition to the error message, parsing result has an `offset` member, which contains the offset of last successfully parsed character. This offset is in units of [link char_t pugi::char_t] (bytes for character mode, wide characters for wide character mode).
-
-[#xpath_parse_result::bool]
-Parsing result object can be implicitly converted to `bool` like this: `if (result) { ... } else { ... }`.
-
-This is an example of XPath error handling ([@samples/xpath_error.cpp]):

-[section:w3c Conformance to W3C specification]
-
-Because of the differences in document object models, performance considerations and implementation complexity, pugixml does not provide a fully conformant XPath 1.0 implementation. This is the current list of incompatibilities:
-
-* Consecutive text nodes sharing the same parent are not merged, i.e. in `<node>text1 <![CDATA[data]]> text2</node>` node should have one text node child, but instead has three.
-* Since the document type declaration is not used for parsing, `id()` function always returns an empty node set.
-* Namespace nodes are not supported (affects namespace:: axis).
-* Name tests are performed on QNames in XML document instead of expanded names; for `<foo xmlns:ns1='uri' xmlns:ns2='uri'><ns1:child/><ns2:child/></foo>`, query `foo/ns1:*` will return only the first child, not both of them. Compliant XPath implementations can return both nodes if the user provides appropriate namespace declarations.
-* String functions consider a character to be either a single `char` value or a single `wchar_t` value, depending on the library configuration; this means that some string functions are not fully Unicode-aware. This affects `substring()`, `string-length()` and `translate()` functions.

-
-Major release, featuring many XPath enhancements, wide character filename support, miscellaneous performance improvements, bug fixes and more.
-
-* XPath:
-    # XPath implementation is moved to pugixml.cpp (which is the only source file now); use PUGIXML_NO_XPATH if you want to disable XPath to reduce code size
-    # XPath is now supported without exceptions (PUGIXML_NO_EXCEPTIONS); the error handling mechanism depends on the presence of exception support
-    # XPath is now supported without STL (PUGIXML_NO_STL)
-    # Introduced variable support
-    # Introduced new xpath_query::evaluate_string, which works without STL
-    # Introduced new xpath_node_set constructor (from an iterator range)

-    # Improved error reporting; now a last parsed offset is returned together with the parsing error
-
-* Bug fixes:
-    # Fixed memory leak for loading from streams with stream exceptions turned on
-    # Fixed custom deallocation function calling with null pointer in one case
-    # Fixed missing attributes for iterator category functions; all functions/classes can now be DLL-exported

-
-* Specification changes:
-    # CDATA nodes containing ]]> are printed as several nodes; while this changes the internal structure, this is the only way to escape CDATA contents
-    # Memory allocation errors during parsing now preserve last parsed offset (to give an idea about parsing progress)
-    # If an element node has the only child, and it is of CDATA type, then the extra indentation is omitted (previously this behavior only held for PCDATA children)
-
-* Additional functionality:
-    # Added xml_parse_result default constructor
-    # Added xml_document::load_file and xml_document::save_file with wide character paths

-    # Minor parsing optimizations
-    # Minor memory optimization for strings in DOM tree (set_name/set_value)
-    # Memory optimization for string memory reclaiming in DOM tree (set_name/set_value now reallocate the buffer if memory waste is too big)
-    # XPath: optimized document order sorting
-    # XPath: optimized child/attribute axis step
-    # XPath: optimized number-to-string conversions in MSVC
-    # XPath: optimized concat for many arguments
-    # XPath: optimized evaluation allocation mechanism: constant and document strings are not heap-allocated

-    # Removed as_utf16 function; use as_wide instead
-
-[h5 1.07.2010 - version 0.9]
-
-Major release, featuring extended and improved Unicode support, miscellaneous performance improvements, bug fixes and more.
-
-* Major Unicode improvements:
-    # Introduced encoding support (automatic/manual encoding detection on load, manual encoding selection on save, conversion from/to UTF8, UTF16 LE/BE, UTF32 LE/BE)
-    # Introduced wchar_t mode (you can set PUGIXML_WCHAR_MODE define to switch pugixml internal encoding from UTF8 to wchar_t; all functions are switched to their Unicode variants)

-
-* Bug fixes:
-    # Fixed document corruption on failed parsing bug
-    # XPath string <-> number conversion improvements (increased precision, fixed crash for huge numbers)

-    # Nodes/attributes with empty names are now printed as :anonymous
-
-* Performance improvements:
-    # Optimized document parsing and saving
-    # Changed internal memory management: internal allocator is used for both metadata and name/value data; allocated pages are deleted if all allocations from them are deleted
-    # Optimized memory consumption: sizeof(xml_node_struct) reduced from 40 bytes to 32 bytes on x86
-    # Optimized debug mode parsing/saving by order of magnitude
-
-* Miscellaneous:
-    # All STL includes except <exception> in pugixml.hpp are replaced with forward declarations
-    # xml_node::remove_child and xml_node::remove_attribute now return the operation result
-
-* Compatibility:
-    # parse() and as_utf16 are left for compatibility (these functions are deprecated and will be removed in version 1.0)

-    # xpath_type_t enumeration was renamed to xpath_value_type; xpath_type_t is deprecated and will be removed in version 1.0
-
-[h5 8.11.2009 - version 0.5]

-
-* XPath bugfixes:
-    # Fixed translate(), lang() and concat() functions (infinite loops/crashes)
-    # Fixed compilation of queries with empty literal strings ("")
-    # Fixed axis tests: they never add empty nodes/attributes to the resulting node set now
-    # Fixed string-value evaluation for node-set (the result excluded some text descendants)
-    # Fixed self:: axis (it behaved like ancestor-or-self::)
-    # Fixed following:: and preceding:: axes (they included descendent and ancestor nodes, respectively)
-    # Minor fix for namespace-uri() function (namespace declaration scope includes the parent element of namespace declaration attribute)
-    # Some incorrect queries are no longer parsed now (i.e. foo: *)
-    # Fixed text()/etc. node test parsing bug (i.e. foo[text()] failed to compile)
-    # Fixed root step (/) - it now selects empty node set if query is evaluated on empty node
-    # Fixed string to number conversion ("123 " converted to NaN, "123 .456" converted to 123.456 - now the results are 123 and NaN, respectively)
-    # Node set copying now preserves sorted type; leads to better performance on some queries
-
-* Miscellaneous bugfixes:
-    # Fixed xml_node::offset_debug for PI nodes
-    # Added empty attribute checks to xml_node::remove_attribute
-    # Fixed node_pi and node_declaration copying
-    # Const-correctness fixes
-
-* Specification changes:
-    # xpath_node::select_nodes() and related functions now throw exception if expression return type is not node set (instead of assertion)
-    # xml_node::traverse() now sets depth to -1 for both begin() and end() callbacks (was 0 at begin() and -1 at end())
-    # In case of non-raw node printing a newline is output after PCDATA inside nodes if the PCDATA has siblings
-    # UTF8 -> wchar_t conversion now considers 5-byte UTF8-like sequences as invalid
-
-* New features:
-    # Added xpath_node_set::operator[] for index-based iteration
-    # Added xpath_query::return_type()
-    # Added getter accessors for memory-management functions
-
-[h5 17.09.2009 - version 0.42]
-
-Maintenance release. Changes:
-
-* Bug fixes:
-    # Fixed deallocation in case of custom allocation functions or if delete[] / free are incompatible

-    # Const-correctness fixes for find_child_by_attribute
-    # Improved compatibility (miscellaneous warning fixes, fixed cstring include dependency for GCC)
-    # Fixed iterator begin/end and print function to work correctly for empty nodes
-
-* New features:

-    # Added xml_attribute::set_value overloads for different types
-
-[h5 8.02.2009 - version 0.41]
-
-Maintenance release. Changes:
-
-* Bug fixes:
-    # Fixed bug with node printing (occasionally some content was not written to output stream)
-
-[h5 18.01.2009 - version 0.4]
-
-Changes:
-
-* Bug fixes:
-    # Documentation fix in samples for parse() with manual lifetime control
-    # Fixed document order sorting in XPath (it caused wrong order of nodes after xpath_node_set::sort and wrong results of some XPath queries)
-
-* Node printing changes:
-    # Single quotes are no longer escaped when printing nodes
-    # Symbols in second half of ASCII table are no longer escaped when printing nodes; because of this, format_utf8 flag is deleted as it's no longer needed and format_write_bom is renamed to format_write_bom_utf8.
-    # Reworked node printing - now it works via xml_writer interface; implementations for FILE* and std::ostream are available. As a side-effect, xml_document::save_file now works without STL.
-
-* New features:
-    # Added unsigned integer support for attributes (xml_attribute::as_uint, xml_attribute::operator=)
-    # Now document declaration (<?xml ...?>) is parsed as node with type node_declaration when parse_declaration flag is specified (access to encoding/version is performed as if they were attributes, i.e. doc.child("xml").attribute("version").as_float()); corresponding flags for node printing were also added
-    # Added support for custom memory management (see set_memory_management_functions for details)
-    # Implemented node/attribute copying (see xml_node::insert\_copy_* and xml_node::append_copy for details)
-    # Added find_child_by_attribute and find_child_by_attribute_w to simplify parsing code in some cases (i.e. COLLADA files)
-    # Added file offset information querying for debugging purposes (now you're able to determine exact location of any xml_node in parsed file, see xml_node::offset_debug for details)
-    # Improved error handling for parsing - now load(), load_file() and parse() return xml_parse_result, which contains error code and last parsed offset; this does not break old interface as xml_parse_result can be implicitly casted to bool.
-

-
-[section:introduction Introduction]
-
-[@http://pugixml.org/ pugixml] is a light-weight C++ XML processing library. It consists of a DOM-like interface with rich traversal/modification capabilities, an extremely fast XML parser which constructs the DOM tree from an XML file/buffer, and an XPath 1.0 implementation for complex data-driven tree queries. Full Unicode support is also available, with Unicode interface variants and conversions between different Unicode encodings (which happen automatically during parsing/saving). The library is extremely portable and easy to integrate and use. pugixml is developed and maintained since 2006 and has many users. All code is distributed under the [link quickstart.main.license MIT license], making it completely free to use in both open-source and proprietary applications.
-
-pugixml enables very fast, convenient and memory-efficient XML document processing. However, since pugixml has a DOM parser, it can't process XML documents that do not fit in memory; also the parser is a non-validating one, so if you need DTD/Schema validation, the library is not for you.
-
-This is the quick start guide for pugixml, which purpose is to enable you to start using the library quickly. Many important library features are either not described at all or only mentioned briefly; for more complete information you [@manual.html should read the complete manual].
-
-[note No documentation is perfect, neither is this one. If you encounter a description that is unclear, please file an issue as described in [sref feedback]. Also if you can spare the time for a full proof-reading, including spelling and grammar, that would be great! Please [link email send me an e-mail]; as a token of appreciation, your name will be included into the corresponding section of the manual.]
-
-[endsect] [/introduction]
-
-[section:install Installation]
-
-pugixml is distributed in source form. You can download a source distribution via one of the following links:
-
-[pre
-[@https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.zip]
-[@https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.tar.gz]
-]
-
-The distribution contains library source, documentation (the guide you're reading now and the manual) and some code examples. After downloading the distribution, install pugixml by extracting all files from the compressed archive. The files have different line endings depending on the archive format - [file .zip] archive has Windows line endings, [file .tar.gz] archive has Unix line endings. Otherwise the files in both archives are identical.
-
-The complete pugixml source consists of three files - one source file, [file pugixml.cpp], and two header files, [file pugixml.hpp] and [file pugiconfig.hpp]. [file pugixml.hpp] is the primary header which you need to include in order to use pugixml classes/functions. The rest of this guide assumes that [file pugixml.hpp] is either in the current directory or in one of include directories of your projects, so that `#include "pugixml.hpp"` can find the header; however you can also use relative path (i.e. `#include "../libs/pugixml/src/pugixml.hpp"`) or include directory-relative path (i.e. `#include <xml/thirdparty/pugixml/src/pugixml.hpp>`).
- 
-The easiest way to build pugixml is to compile the source file, [file pugixml.cpp], along with the existing library/executable. This process depends on the method of building your application; for example, if you're using Microsoft Visual Studio[ftnt trademarks All trademarks used are properties of their respective owners.], Apple Xcode, Code::Blocks or any other IDE, just add [file pugixml.cpp] to one of your projects. There are other building methods available, including building pugixml as a standalone static/shared library; [@manual/install.html#manual.install.building read the manual] for further information.

-
-[section:dom Document object model]
-
-pugixml stores XML data in DOM-like way: the entire XML document (both document structure and element data) is stored in memory as a tree. The tree can be loaded from character stream (file, string, C++ I/O stream), then traversed via special API or XPath expressions. The whole tree is mutable: both node structure and node/attribute data can be changed at any time. Finally, the result of document transformations can be saved to a character stream (file, C++ I/O stream or custom transport).
-
-The root of the tree is the document itself, which corresponds to C++ type `xml_document`. Document has one or more child nodes, which correspond to C++ type `xml_node`. Nodes have different types; depending on a type, a node can have a collection of child nodes, a collection of attributes, which correspond to C++ type `xml_attribute`, and some additional data (i.e. name).
-
-The most common node types are:
-
-* Document node (`node_document`) - this is the root of the tree, which consists of several child nodes. This node corresponds to `xml_document` class; note that `xml_document` is a sub-class of `xml_node`, so the entire node interface is also available.
-* Element/tag node (`node_element`) - this is the most common type of node, which represents XML elements. Element nodes have a name, a collection of attributes and a collection of child nodes (both of which may be empty). The attribute is a simple name/value pair.
-* Plain character data nodes (`node_pcdata`) represent plain text in XML. PCDATA nodes have a value, but do not have name or children/attributes. Note that *plain character data is not a part of the element node but instead has its own node*; for example, an element node can have several child PCDATA nodes.
-
-Despite the fact that there are several node types, there are only three C++ types representing the tree (`xml_document`, `xml_node`, `xml_attribute`); some operations on `xml_node` are only valid for certain node types. They are described below.
-
-[note All pugixml classes and functions are located in `pugi` namespace; you have to either use explicit name qualification (i.e. `pugi::xml_node`), or to gain access to relevant symbols via `using` directive (i.e. `using pugi::xml_node;` or `using namespace pugi;`).]
-
-`xml_document` is the owner of the entire document structure; destroying the document destroys the whole tree. The interface of `xml_document` consists of loading functions, saving functions and the entire interface of `xml_node`, which allows for document inspection and/or modification. Note that while `xml_document` is a sub-class of `xml_node`, `xml_node` is not a polymorphic type; the inheritance is present only to simplify usage.
-
-`xml_node` is the handle to document node; it can point to any node in the document, including document itself. There is a common interface for nodes of all types. Note that `xml_node` is only a handle to the actual node, not the node itself - you can have several `xml_node` handles pointing to the same underlying object. Destroying `xml_node` handle does not destroy the node and does not remove it from the tree.
-
-There is a special value of `xml_node` type, known as null node or empty node. It does not correspond to any node in any document, and thus resembles null pointer. However, all operations are defined on empty nodes; generally the operations don't do anything and return empty nodes/attributes or empty strings as their result. This is useful for chaining calls; i.e. you can get the grandparent of a node like so: `node.parent().parent()`; if a node is a null node or it does not have a parent, the first `parent()` call returns null node; the second `parent()` call then also returns null node, so you don't have to check for errors twice. You can test if a handle is null via implicit boolean cast: `if (node) { ... }` or `if (!node) { ... }`.
-
-`xml_attribute` is the handle to an XML attribute; it has the same semantics as `xml_node`, i.e. there can be several `xml_attribute` handles pointing to the same underlying object and there is a special null attribute value, which propagates to function results.
-
-There are two choices of interface and internal representation when configuring pugixml: you can either choose the UTF-8 (also called char) interface or UTF-16/32 (also called wchar_t) one. The choice is controlled via `PUGIXML_WCHAR_MODE` define; you can set it via [file pugiconfig.hpp] or via preprocessor options. All tree functions that work with strings work with either C-style null terminated strings or STL strings of the selected character type. [@manual/dom.html#manual.dom.unicode Read the manual] for additional information on Unicode interface.

-
-[section:loading Loading document]
-
-pugixml provides several functions for loading XML data from various places - files, C++ iostreams, memory buffers. All functions use an extremely fast non-validating parser. This parser is not fully W3C conformant - it can load any valid XML document, but does not perform some well-formedness checks. While considerable effort is made to reject invalid XML documents, some validation is not performed because of performance reasons. XML data is always converted to internal character format before parsing. pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it's a strict subset of UTF-16) and handles all encoding conversions automatically.
-
-The most common source of XML data is files; pugixml provides a separate function for loading XML document from file. This function accepts file path as its first argument, and also two optional arguments, which specify parsing options and input data encoding, which are described in the manual.
-
-This is an example of loading XML document from file ([@samples/load_file.cpp]):
-
-[import samples/load_file.cpp]
-[code_load_file]
-
-`load_file`, as well as other loading functions, destroys the existing document tree and then tries to load the new tree from the specified file. The result of the operation is returned in an `xml_parse_result` object; this object contains the operation status, and the related information (i.e. last successfully parsed position in the input file, if parsing fails).
-
-Parsing result object can be implicitly converted to `bool`; if you do not want to handle parsing errors thoroughly, you can just check the return value of load functions as if it was a `bool`: `if (doc.load_file("file.xml")) { ... } else { ... }`. Otherwise you can use the `status` member to get parsing status, or the `description()` member function to get the status in a string form.
-
-This is an example of handling loading errors ([@samples/load_error_handling.cpp]):
-
-[import samples/load_error_handling.cpp]
-[code_load_error_handling]
-
-Sometimes XML data should be loaded from some other source than file, i.e. HTTP URL; also you may want to load XML data from file using non-standard functions, i.e. to use your virtual file system facilities or to load XML from gzip-compressed files. These scenarios either require loading document from memory, in which case you should prepare a contiguous memory block with all XML data and to pass it to one of buffer loading functions, or loading document from C++ IOstream, in which case you should provide an object which implements `std::istream` or `std::wistream` interface.
-
-There are different functions for loading document from memory; they treat the passed buffer as either an immutable one (`load_buffer`), a mutable buffer which is owned by the caller (`load_buffer_inplace`), or a mutable buffer which ownership belongs to pugixml (`load_buffer_inplace_own`). There is also a simple helper function, `xml_document::load`, for cases when you want to load the XML document from null-terminated character string.
-
-This is an example of loading XML document from memory using one of these functions ([@samples/load_memory.cpp]); read the sample code for more examples:
-
-[import samples/load_memory.cpp]
-[code_load_memory_decl]
-[code_load_memory_buffer_inplace]
-
-This is a simple example of loading XML document from file using streams ([@samples/load_stream.cpp]); read the sample code for more complex examples involving wide streams and locales:
-
-[import samples/load_stream.cpp]
-[code_load_stream]
-
-[endsect] [/loading]
-
-[section:access Accessing document data]
-
-pugixml features an extensive interface for getting various types of data from the document and for traversing the document. You can use various accessors to get node/attribute data, you can traverse the child node/attribute lists via accessors or iterators, you can do depth-first traversals with `xml_tree_walker` objects, and you can use XPath for complex data-driven queries.
-
-You can get node or attribute name via `name()` accessor, and value via `value()` accessor. Note that both functions never return null pointers - they either return a string with the relevant content, or an empty string if name/value is absent or if the handle is null. Also there are two notable things for reading values:
-
-* It is common to store data as text contents of some node - i.e. `<node><description>This is a node</description></node>`. In this case, `<description>` node does not have a value, but instead has a child of type `node_pcdata` with value `"This is a node"`. pugixml provides `child_value()` and `text()` helper functions to parse such data.
-
-* In many cases attribute values have types that are not strings - i.e. an attribute may always contain values that should be treated as integers, despite the fact that they are represented as strings in XML. pugixml provides several accessors that convert attribute value to some other type.
-
-This is an example of using these functions ([@samples/traverse_base.cpp]):
-
-[import samples/traverse_base.cpp]
-[code_traverse_base_data]
-
-Since a lot of document traversal consists of finding the node/attribute with the correct name, there are special functions for that purpose. For example, `child("Tool")` returns the first node which has the name `"Tool"`, or null handle if there is no such node. This is an example of using such functions ([@samples/traverse_base.cpp]):
-
-[code_traverse_base_contents]
-
-Child node lists and attribute lists are simply double-linked lists; while you can use `previous_sibling`/`next_sibling` and other such functions for iteration, pugixml additionally provides node and attribute iterators, so that you can treat nodes as containers of other nodes or attributes. All iterators are bidirectional and support all usual iterator operations. The iterators are invalidated if the node\/attribute objects they're pointing to are removed from the tree; adding nodes\/attributes does not invalidate any iterators.
-
-Here is an example of using iterators for document traversal ([@samples/traverse_iter.cpp]):
-
-[import samples/traverse_iter.cpp]
-[code_traverse_iter]
-
-If your C++ compiler supports range-based for-loop (this is a C++11 feature, at the time of writing it's supported by Microsoft Visual Studio 11 Beta, GCC 4.6 and Clang 3.0), you can use it to enumerate nodes/attributes. Additional helpers are provided to support this; note that they are also compatible with [@http://www.boost.org/libs/foreach/ Boost Foreach], and possibly other pre-C++11 foreach facilities.
-
-Here is an example of using C++11 range-based for loop for document traversal ([@samples/traverse_rangefor.cpp]):
-
-[import samples/traverse_rangefor.cpp]
-[code_traverse_rangefor]
-
-The methods described above allow traversal of immediate children of some node; if you want to do a deep tree traversal, you'll have to do it via a recursive function or some equivalent method. However, pugixml provides a helper for depth-first traversal of a subtree. In order to use it, you have to implement `xml_tree_walker` interface and to call `traverse` function.
-
-This is an example of traversing tree hierarchy with xml_tree_walker ([@samples/traverse_walker.cpp]):
-
-[import samples/traverse_walker.cpp]
-[code_traverse_walker_impl]
-[code_traverse_walker_traverse]
-
-Finally, for complex queries often a higher-level DSL is needed. pugixml provides an implementation of XPath 1.0 language for such queries. The complete description of XPath usage can be found in the manual, but here are some examples:
-
-[import samples/xpath_select.cpp]
-[code_xpath_select]
-
-[caution XPath functions throw `xpath_exception` objects on error; the sample above does not catch these exceptions.]
-
-[endsect] [/access]
-
-[section:modify Modifying document data]
-
-The document in pugixml is fully mutable: you can completely change the document structure and modify the data of nodes/attributes. All functions take care of memory management and structural integrity themselves, so they always result in structurally valid tree - however, it is possible to create an invalid XML tree (for example, by adding two attributes with the same name or by setting attribute/node name to empty/invalid string). Tree modification is optimized for performance and for memory consumption, so if you have enough memory you can create documents from scratch with pugixml and later save them to file/stream instead of relying on error-prone manual text writing and without too much overhead.
-
-All member functions that change node/attribute data or structure are non-constant and thus can not be called on constant handles. However, you can easily convert constant handle to non-constant one by simple assignment: `void foo(const pugi::xml_node& n) { pugi::xml_node nc = n; }`, so const-correctness here mainly provides additional documentation.
-
-As discussed before, nodes can have name and value, both of which are strings. Depending on node type, name or value may be absent. You can use `set_name` and `set_value` member functions to set them. Similar functions are available for attributes; however, the `set_value` function is overloaded for some other types except strings, like floating-point numbers. Also, attribute value can be set using an assignment operator. This is an example of setting node/attribute name and value ([@samples/modify_base.cpp]):
-
-[import samples/modify_base.cpp]
-[code_modify_base_node]
-[code_modify_base_attr]
-
-Nodes and attributes do not exist without a document tree, so you can't create them without adding them to some document. A node or attribute can be created at the end of node/attribute list or before\/after some other node. All insertion functions return the handle to newly created object on success, and null handle on failure. Even if the operation fails (for example, if you're trying to add a child node to PCDATA node), the document remains in consistent state, but the requested node/attribute is not added.
-
-[caution attribute() and child() functions do not add attributes or nodes to the tree, so code like `node.attribute("id") = 123;` will not do anything if `node` does not have an attribute with name `"id"`. Make sure you're operating with existing attributes/nodes by adding them if necessary.]
-
-This is an example of adding new attributes\/nodes to the document ([@samples/modify_add.cpp]):
-
-[import samples/modify_add.cpp]
-[code_modify_add]
-
-If you do not want your document to contain some node or attribute, you can remove it with `remove_attribute` and `remove_child` functions. Removing the attribute or node invalidates all handles to the same underlying object, and also invalidates all iterators pointing to the same object. Removing node also invalidates all past-the-end iterators to its attribute or child node list. Be careful to ensure that all such handles and iterators either do not exist or are not used after the attribute\/node is removed.
-
-This is an example of removing attributes\/nodes from the document ([@samples/modify_remove.cpp]):
-
-[import samples/modify_remove.cpp]
-[code_modify_remove]
-
-[endsect] [/modify]
-
-[section:saving Saving document]
-
-Often after creating a new document or loading the existing one and processing it, it is necessary to save the result back to file. Also it is occasionally useful to output the whole document or a subtree to some stream; use cases include debug printing, serialization via network or other text-oriented medium, etc. pugixml provides several functions to output any subtree of the document to a file, stream or another generic transport interface; these functions allow to customize the output format, and also perform necessary encoding conversions.
-
-Before writing to the destination the node/attribute data is properly formatted according to the node type; all special XML symbols, such as < and &, are properly escaped. In order to guard against forgotten node/attribute names, empty node/attribute names are printed as `":anonymous"`. For well-formed output, make sure all node and attribute names are set to meaningful values.
-
-If you want to save the whole document to a file, you can use the `save_file` function, which returns `true` on success. This is a simple example of saving XML document to file ([@samples/save_file.cpp]):
-
-[import samples/save_file.cpp]
-[code_save_file]
-
-To enhance interoperability pugixml provides functions for saving document to any object which implements C++ `std::ostream` interface. This allows you to save documents to any standard C++ stream (i.e. file stream) or any third-party compliant implementation (i.e. Boost Iostreams). Most notably, this allows for easy debug output, since you can use `std::cout` stream as saving target. There are two functions, one works with narrow character streams, another handles wide character ones.
-
-This is a simple example of saving XML document to standard output ([@samples/save_stream.cpp]):
-
-[import samples/save_stream.cpp]
-[code_save_stream]
-
-All of the above saving functions are implemented in terms of writer interface. This is a simple interface with a single function, which is called several times during output process with chunks of document data as input. In order to output the document via some custom transport, for example sockets, you should create an object which implements `xml_writer_file` interface and pass it to `xml_document::save` function.
-
-This is a simple example of custom writer for saving document data to STL string ([@samples/save_custom_writer.cpp]); read the sample code for more complex examples:
-
-[import samples/save_custom_writer.cpp]
-[code_save_custom_writer]
-
-While the previously described functions save the whole document to the destination, it is easy to save a single subtree. Instead of calling `xml_document::save`, just call `xml_node::print` function on the target node. You can save node contents to C++ IOstream object or custom writer in this way. Saving a subtree slightly differs from saving the whole document; [@manual/saving.html#manual.saving.subtree read the manual] for more information.

Often whitespace-only data is not significant for the application, and the cost of allocating and storing such nodes (both memory and speed-wise) can be significant. For example, after parsing XML string `<node> <a/> </node>`, `<node>` element will have three children when `parse_ws_pcdata` is set (child with type <<node_pcdata,node_pcdata>> and value `" "`, child with type <<node_element,node_element>> and name `"a"`, and another child with type <<node_pcdata,node_pcdata>> and value `" "`), and only one child when `parse_ws_pcdata` is not set. This flag is *off* by default.

If character/entity reference can not be expanded, it is left as is, so you can do additional processing later. Reference expansion is performed on attribute values and PCDATA content. This flag is *on* by default.
 
-* [[parse_eol]]`parse_eol` determines if EOL handling (that is, replacing sequences `0x0d 0x0a` by a single `0x0a` character, and replacing all standalone `0x0d` characters by `0x0a`) is to be performed on input data (that is, comments contents, PCDATA/CDATA contents and attribute values).

Boolean type corresponds to `bool` type, number type corresponds to `double` type, string type corresponds to either `std::string` or `std::wstring`, depending on whether <<manual.dom.unicode,wide character interface is enabled>>, and node set corresponds to <<xpath_node_set,xpath_node_set>> type. There is an enumeration, `xpath_value_type`, which can take the values `xpath_type_boolean`, `xpath_type_number`, `xpath_type_string` or `xpath_type_node_set`, accordingly.

 [[xpath_node]][[xpath_node::node]][[xpath_node::attribute]][[xpath_node::parent]]
 Because an XPath node can be either a node or an attribute, there is a special type, `xpath_node`, which is a discriminated union of these types. A value of this type contains two node handles, one of `xml_node` type, and another one of `xml_attribute` type; at most one of them can be non-null. The accessors to get these handles are available:

 ==== Building pugixml as a standalone static library
  
-It's possible to compile pugixml as a standalone static library. This process depends on the method of building your application; pugixml distribution comes with project files for several popular IDEs/build systems. There are project files for Apple XCode3, Code::Blocks, Codelite, Microsoft Visual Studio 2005, 2008, 2010, and configuration scripts for CMake and premake4. You're welcome to submit project files/build scripts for other software; see <<overview.feedback>>.

You're welcome to submit project files/build scripts for other software; see <<overview.feedback>>. 
 
 There are two projects for each version of Microsoft Visual Studio: one for dynamically linked CRT, which has a name like `pugixml_vs2008.vcproj`, and another one for statically linked CRT, which has a name like `pugixml_vs2008_static.vcproj`. You should select the version that matches the CRT used in your application; the default option for new projects created by Microsoft Visual Studio is dynamically linked CRT, so unless you changed the defaults, you should use the version with dynamic CRT (i.e. `pugixml_vs2008.vcproj` for Microsoft Visual Studio 2008).
 
-In addition to adding pugixml project to your workspace, you'll have to make sure that your application links with pugixml library. If you're using Microsoft Visual Studio 2005/2008, you can add a dependency from your application project to pugixml one. If you're using Microsoft Visual Studio 2010, you'll have to add a reference to your application project instead. For other IDEs/systems, consult the relevant documentation.

 Both functions try to set the name/value to the specified string, and return the operation result. The operation fails if the node can not have name or value (for instance, when trying to call `set_name` on a <<node_pcdata,node_pcdata>> node), if the node handle is null, or if there is insufficient memory to handle the request. The provided string is copied into document managed memory and can be destroyed after the function returns (for example, you can safely pass stack-allocated buffers to these functions). The name/value content is not verified, so take care to use only valid XML names, or the document may become malformed.

 Often after creating a new document or loading the existing one and processing it, it is necessary to save the result back to file. Also it is occasionally useful to output the whole document or a subtree to some stream; use cases include debug printing, serialization via network or other text-oriented medium, etc. pugixml provides several functions to output any subtree of the document to a file, stream or another generic transport interface; these functions allow to customize the output format (see <<saving.options>>), and also perform necessary encoding conversions (see <<saving.encoding>>). This section documents the relevant functionality.

+The distribution contains library source, documentation (the guide you're reading now and the manual) and some code examples. After downloading the distribution, install pugixml by extracting all files from the compressed archive.
 
 The complete pugixml source consists of three files - one source file, `pugixml.cpp`, and two header files, `pugixml.hpp` and `pugiconfig.hpp`. `pugixml.hpp` is the primary header which you need to include in order to use pugixml classes/functions. The rest of this guide assumes that `pugixml.hpp` is either in the current directory or in one of include directories of your projects, so that `#include "pugixml.hpp"` can find the header; however you can also use relative path (i.e. `#include "../libs/pugixml/src/pugixml.hpp"`) or include directory-relative path (i.e. `#include <xml/thirdparty/pugixml/src/pugixml.hpp>`).

+<div class="paragraph">
+<p><a href="http://pugixml.org/">pugixml</a> is a light-weight C&#43;&#43; XML processing library. It consists of a DOM-like interface with rich traversal/modification capabilities, an extremely fast XML parser which constructs the DOM tree from an XML file/buffer, and an <a href="#xpath">XPath 1.0 implementation</a> for complex data-driven tree queries. Full Unicode support is also available, with <a href="#dom.unicode">two Unicode interface variants</a> and conversions between different Unicode encodings (which happen automatically during parsing/saving). The library is <a href="#install.portability">extremely portable</a> and easy to integrate and use. pugixml is developed and maintained since 2006 and has many users. All code is distributed under the <a href="#overview.license">MIT license</a>, making it completely free to use in both open-source and proprietary applications.</p>
+</div>
+<div class="paragraph">
+<p>pugixml enables very fast, convenient and memory-efficient XML document processing. However, since pugixml has a DOM parser, it can&#8217;t process XML documents that do not fit in memory; also the parser is a non-validating one, so if you need DTD or XML Schema validation, the library is not for you.</p>
+</div>
+<div class="paragraph">
+<p>This is the complete manual for pugixml, which describes all features of the library in detail. If you want to start writing code as quickly as possible, you are advised to <a href="quickstart.html">read the quick start guide first</a>.</p>

+<div class="paragraph">
+<p>If you believe you&#8217;ve found a bug in pugixml (bugs include compilation problems (errors/warnings), crashes, performance degradation and incorrect behavior), please file an issue via <a href="https://github.com/zeux/pugixml/issues/new">issue submission form</a>. Be sure to include the relevant information so that the bug can be reproduced: the version of pugixml, compiler version and target architecture, the code that uses pugixml and exhibits the bug, etc.</p>
+</div>
+<div class="paragraph">
+<p>Feature requests can be reported the same way as bugs, so if you&#8217;re missing some functionality in pugixml or if the API is rough in some places and you can suggest an improvement, <a href="https://github.com/zeux/pugixml/issues/new">file an issue</a>. However please note that there are many factors when considering API changes (compatibility with previous versions, API redundancy, etc.), so generally features that can be implemented via a small function without pugixml modification are not accepted. However, all rules have exceptions.</p>
+</div>
+<div class="paragraph">
+<p>If you have a contribution to pugixml, such as build script for some build system/IDE, or a well-designed set of helper functions, or a binding to some language other than C&#43;&#43;, please <a href="https://github.com/zeux/pugixml/issues/new">file an issue or open a pull request</a>. Your contribution has to be distributed under the terms of a license that&#8217;s compatible with pugixml license; i.e. GPL/LGPL licensed code is not accepted.</p>

The rest of this guide assumes that <code>pugixml.hpp</code> is either in the current directory or in one of include directories of your projects, so that <code>#include "pugixml.hpp"</code> can find the header; however you can also use relative path (i.e. <code>#include "../libs/pugixml/src/pugixml.hpp"</code>) or include directory-relative path (i.e. <code>#include &lt;xml/thirdparty/pugixml/src/pugixml.hpp&gt;</code>).</p>

+<p>It&#8217;s possible to compile pugixml as a standalone static library. This process depends on the method of building your application; pugixml distribution comes with project files for several popular IDEs/build systems. There are project files for Apple XCode, Code::Blocks, Codelite, Microsoft Visual Studio 2005, 2008, 2010+, and configuration scripts for CMake and premake4. You&#8217;re welcome to submit project files/build scripts for other software; see <a href="#overview.feedback">Feedback</a>.</p>

You should select the version that matches the CRT used in your application; the default option for new projects created by Microsoft Visual Studio is dynamically linked CRT, so unless you changed the defaults, you should use the version with dynamic CRT (i.e. <code>pugixml_vs2008.vcproj</code> for Microsoft Visual Studio 2008).</p>

If you&#8217;re using Microsoft Visual Studio 2010+, you&#8217;ll have to add a reference to your application project instead. For other IDEs/systems, consult the relevant documentation.</p>

+<p>It&#8217;s possible to compile pugixml as a standalone shared library. The process is usually similar to the static library approach; however, no preconfigured projects/scripts are included into pugixml distribution, so you&#8217;ll have to do it yourself. Generally, if you&#8217;re using GCC-based toolchain, the process does not differ from building any other library as DLL (adding -shared to compilation flags should suffice); if you&#8217;re using MSVC-based toolchain, you&#8217;ll have to explicitly mark exported symbols with a declspec attribute. You can do it by defining <a href="#PUGIXML_API">PUGIXML_API</a> macro, i.e. via <code>pugiconfig.hpp</code>:</p>

+<div id="PUGIXML_HEADER_ONLY" class="paragraph">
+<p>It&#8217;s possible to use pugixml in header-only mode. This means that all source code for pugixml will be included in every translation unit that includes <code>pugixml.hpp</code>. This is how most of Boost and STL libraries work.</p>
+</div>
+<div class="paragraph">
+<p>Note that there are advantages and drawbacks of this approach. Header mode may improve tree traversal/modification performance (because many simple functions will be inlined), if your compiler toolchain does not support link-time optimization, or if you have it turned off (with link-time optimization the performance should be similar to non-header mode). However, since compiler now has to compile pugixml source once for each translation unit that includes it, compilation times may increase noticeably. If you want to use pugixml in header mode but do not need XPath support, you can consider disabling it by using <a href="#PUGIXML_NO_XPATH">PUGIXML_NO_XPATH</a> define to improve compilation time.</p>
+</div>
+<div class="paragraph">
+<p>To enable header-only mode, you have to define <code>PUGIXML_HEADER_ONLY</code>. You can either do it in <code>pugiconfig.hpp</code>, or provide them via compiler command-line.</p>
+</div>
+<div class="paragraph">
+<p>Note that it is safe to compile <code>pugixml.cpp</code> if <code>PUGIXML_HEADER_ONLY</code> is defined - so if you want to i.e. use header-only mode only in Release configuration, you
+can include pugixml.cpp in your project (see <a href="#install.building.embed">Building pugixml as a part of another static library/executable</a>), and conditionally enable header-only mode in <code>pugiconfig.hpp</code> like this:</p>

+<p>pugixml uses several defines to control the compilation process. There are two ways to define them: either put the needed definitions to <code>pugiconfig.hpp</code> (it has some examples that are commented out) or provide them via compiler command-line. Consistency is important: the definitions should match in all source files that include <code>pugixml.hpp</code> (including pugixml sources) throughout the application. Adding defines to <code>pugiconfig.hpp</code> lets you guarantee this, unless your macro definition is wrapped in preprocessor <code>#if</code>/<code>#ifdef</code> directive and this directive is not consistent. <code>pugiconfig.hpp</code> will never contain anything but comments, which means that when upgrading to a new version, you can safely leave your modified version intact.</p>

In absence of <code>PUGIXML_CLASS</code> or <code>PUGIXML_FUNCTION</code> definitions, <code>PUGIXML_API</code> definition is used instead. For example, to specify fixed calling convention, you can define <code>PUGIXML_FUNCTION</code> to i.e. <code>__fastcall</code>.

+<p>pugixml stores XML data in DOM-like way: the entire XML document (both document structure and element data) is stored in memory as a tree. The tree can be loaded from a character stream (file, string, C&#43;&#43; I/O stream), then traversed with the special API or XPath expressions. The whole tree is mutable: both node structure and node/attribute data can be changed at any time. Finally, the result of document transformations can be saved to a character stream (file, C&#43;&#43; I/O stream or custom transport).</p>

+<h3 id="dom.tree"><a class="anchor" href="#dom.tree"></a>3.1. Tree structure</h3>
+<div class="paragraph">
+<p>The XML document is represented with a tree data structure. The root of the tree is the document itself, which corresponds to C&#43;&#43; type <a href="#xml_document">xml_document</a>. Document has one or more child nodes, which correspond to C&#43;&#43; type <a href="#xml_node">xml_node</a>. Nodes have different types; depending on a type, a node can have a collection of child nodes, a collection of attributes, which correspond to C&#43;&#43; type <a href="#xml_attribute">xml_attribute</a>, and some additional data (i.e. name).</p>
+</div>
+<div id="xml_node_type" class="paragraph">
+<p>The tree nodes can be of one of the following types (which together form the enumeration <code>xml_node_type</code>):</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>Document node (<a id="node_document"></a><code>node_document</code>) - this is the root of the tree, which consists of several child nodes. This node corresponds to <a href="#xml_document">xml_document</a> class; note that <a href="#xml_document">xml_document</a> is a sub-class of <a href="#xml_node">xml_node</a>, so the entire node interface is also available. However, document node is special in several ways, which are covered below. There can be only one document node in the tree; document node does not have any XML representation.</p>
+</li>
+<li>
+<p>Element/tag node (<a id="node_element"></a><code>node_element</code>) - this is the most common type of node, which represents XML elements. Element nodes have a name, a collection of attributes and a collection of child nodes (both of which may be empty). The attribute is a simple name/value pair. The example XML representation of element nodes is as follows:</p>
+<div class="listingblock">
+<div class="content">
+<pre>&lt;node attr="value"&gt;&lt;child/&gt;&lt;/node&gt;</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>There are two element nodes here: one has name <code>"node"</code>, single attribute <code>"attr"</code> and single child <code>"child"</code>, another has name <code>"child"</code> and does not have any attributes or child nodes.</p>
+</div>
+</li>
+<li>
+<p>Plain character data nodes (<a id="node_pcdata"></a><code>node_pcdata</code>) represent plain text in XML. PCDATA nodes have a value, but do not have a name or children/attributes. Note that <strong>plain character data is not a part of the element node but instead has its own node</strong>; an element node can have several child PCDATA nodes. The example XML representation of text nodes is as follows:</p>
+<div class="listingblock">
+<div class="content">
+<pre>&lt;node&gt; text1 &lt;child/&gt; text2 &lt;/node&gt;</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Here <code>"node"</code> element has three children, two of which are PCDATA nodes with values <code>" text1 "</code> and <code>" text2 "</code>.</p>
+</div>
+</li>
+<li>
+<p>Character data nodes (<a id="node_cdata"></a><code>node_cdata</code>) represent text in XML that is quoted in a special way. CDATA nodes do not differ from PCDATA nodes except in XML representation - the above text example looks like this with CDATA:</p>
+<div class="listingblock">
+<div class="content">
+<pre>&lt;node&gt; &lt;![CDATA[[text1]]&gt; &lt;child/&gt; &lt;![CDATA[[text2]]&gt; &lt;/node&gt;</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>CDATA nodes make it easy to include non-escaped <code>&lt;</code>, <code>&amp;</code> and <code>&gt;</code> characters in plain text. CDATA value can not contain the character sequence <code>]]&gt;</code>, since it is used to determine the end of node contents.</p>
+</div>
+</li>
+<li>
+<p>Comment nodes (<a id="node_comment"></a><code>node_comment</code>) represent comments in XML. Comment nodes have a value, but do not have a name or children/attributes. The example XML representation of a comment node is as follows:</p>
+<div class="listingblock">
+<div class="content">
+<pre>&lt;!-- comment text --&gt;</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Here the comment node has value <code>"comment text"</code>. By default comment nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with <a href="#parse_comments">parse_comments</a> flag.</p>
+</div>
+</li>
+<li>
+<p>Processing instruction node (<a id="node_pi"></a><code>node_pi</code>) represent processing instructions (PI) in XML. PI nodes have a name and an optional value, but do not have children/attributes. The example XML representation of a PI node is as follows:</p>
+<div class="listingblock">
+<div class="content">
+<pre>&lt;?name value?&gt;</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Here the name (also called PI target) is <code>"name"</code>, and the value is <code>"value"</code>. By default PI nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with <a href="#parse_pi">parse_pi</a> flag.</p>
+</div>
+</li>
+<li>
+<p>Declaration node (<a id="node_declaration"></a><code>node_declaration</code>) represents document declarations in XML. Declaration nodes have a name (<code>"xml"</code>) and an optional collection of attributes, but do not have value or children. There can be only one declaration node in a document; moreover, it should be the topmost node (its parent should be the document). The example XML representation of a declaration node is as follows:</p>
+<div class="listingblock">
+<div class="content">
+<pre>&lt;?xml version="1.0"?&gt;</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Here the node has name <code>"xml"</code> and a single attribute with name <code>"version"</code> and value <code>"1.0"</code>. By default declaration nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with <a href="#parse_declaration">parse_declaration</a> flag. Also, by default a dummy declaration is output when XML document is saved unless there is already a declaration in the document; you can disable this with <a href="#format_no_declaration">format_no_declaration</a> flag.</p>
+</div>
+</li>
+<li>
+<p>Document type declaration node (<a id="node_doctype"></a><code>node_doctype</code>) represents document type declarations in XML. Document type declaration nodes have a value, which corresponds to the entire document type contents; no additional nodes are created for inner elements like <code>&lt;!ENTITY&gt;</code>. There can be only one document type declaration node in a document; moreover, it should be the topmost node (its parent should be the document). The example XML representation of a document type declaration node is as follows:</p>
+<div class="listingblock">
+<div class="content">
+<pre>&lt;!DOCTYPE greeting [ &lt;!ELEMENT greeting (#PCDATA)&gt; ]&gt;</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Here the node has value <code>"greeting [ &lt;!ELEMENT greeting (#PCDATA)&gt; ]"</code>. By default document type declaration nodes are treated as non-essential part of XML markup and are not loaded during XML parsing. You can override this behavior with <a href="#parse_doctype">parse_doctype</a> flag.</p>

+<p>Despite the fact that there are several node types, there are only three C&#43;&#43; classes representing the tree (<code>xml_document</code>, <code>xml_node</code>, <code>xml_attribute</code>); some operations on <code>xml_node</code> are only valid for certain node types. The classes are described below.</p>
+</div>
+<div class="paragraph">
+<p><a id="xml_document"></a><a id="xml_document::document_element"></a>
+<code>xml_document</code> is the owner of the entire document structure; it is a non-copyable class. The interface of <code>xml_document</code> consists of loading functions (see <a href="#loading">Loading document</a>), saving functions (see <a href="#saving">Saving document</a>) and the entire interface of <code>xml_node</code>, which allows for document inspection and/or modification. Note that while <code>xml_document</code> is a sub-class of <code>xml_node</code>, <code>xml_node</code> is not a polymorphic type; the inheritance is present only to simplify usage. Alternatively you can use the <code>document_element</code> function to get the element node that&#8217;s the immediate child of the document.</p>
+</div>
+<div class="paragraph">
+<p><a id="xml_document::ctor"></a><a id="xml_document::dtor"></a><a id="xml_document::reset"></a>
+Default constructor of <code>xml_document</code> initializes the document to the tree with only a root node (document node). You can then populate it with data using either tree modification functions or loading functions; all loading functions destroy the previous tree with all occupied memory, which puts existing node/attribute handles for this document to invalid state. If you want to destroy the previous tree, you can use the <code>xml_document::reset</code> function; it destroys the tree and replaces it with either an empty one or a copy of the specified document. Destructor of <code>xml_document</code> also destroys the tree, thus the lifetime of the document object should exceed the lifetimes of any node/attribute handles that point to the tree.</p>

+While technically node/attribute handles can be alive when the tree they&#8217;re referring to is destroyed, calling any member function for these handles results in undefined behavior. Thus it is recommended to make sure that the document is destroyed only after all references to its nodes/attributes are destroyed.

+<p><a id="xml_node"></a><a id="xml_node::type"></a>
+<code>xml_node</code> is the handle to document node; it can point to any node in the document, including the document node itself. There is a common interface for nodes of all types; the actual <a href="#xml_node_type">node type</a> can be queried via the <code>xml_node::type()</code> method. Note that <code>xml_node</code> is only a handle to the actual node, not the node itself - you can have several <code>xml_node</code> handles pointing to the same underlying object. Destroying <code>xml_node</code> handle does not destroy the node and does not remove it from the tree. The size of <code>xml_node</code> is equal to that of a pointer, so it is nothing more than a lightweight wrapper around a pointer; you can safely pass or return <code>xml_node</code> objects by value without additional overhead.</p>
+</div>
+<div id="node_null" class="paragraph">
+<p>There is a special value of <code>xml_node</code> type, known as null node or empty node (such nodes have type <code>node_null</code>). It does not correspond to any node in any document, and thus resembles null pointer. However, all operations are defined on empty nodes; generally the operations don&#8217;t do anything and return empty nodes/attributes or empty strings as their result (see documentation for specific functions for more detailed information). This is useful for chaining calls; i.e. you can get the grandparent of a node like so: <code>node.parent().parent()</code>; if a node is a null node or it does not have a parent, the first <code>parent()</code> call returns null node; the second <code>parent()</code> call then also returns null node, which makes error handling easier.</p>
+</div>
+<div id="xml_attribute" class="paragraph">
+<p><code>xml_attribute</code> is the handle to an XML attribute; it has the same semantics as <code>xml_node</code>, i.e. there can be several <code>xml_attribute</code> handles pointing to the same underlying object and there is a special null attribute value, which propagates to function results.</p>
+</div>
+<div class="paragraph">
+<p><a id="xml_attribute::ctor"></a><a id="xml_node::ctor"></a>
+Both <code>xml_node</code> and <code>xml_attribute</code> have the default constructor which initializes them to null objects.</p>

+<div class="paragraph">
+<p><a id="xml_attribute::comparison"></a><a id="xml_node::comparison"></a>
+<code>xml_node</code> and <code>xml_attribute</code> try to behave like pointers, that is, they can be compared with other objects of the same type, making it possible to use them as keys in associative containers. All handles to the same underlying object are equal, and any two handles to different underlying objects are not equal. Null handles only compare as equal to themselves. The result of relational comparison can not be reliably determined from the order of nodes in file or in any other way. Do not use relational comparison operators except for search optimization (i.e. associative container keys).</p>
+</div>
+<div class="paragraph">
+<p><a id="xml_attribute::hash_value"></a><a id="xml_node::hash_value"></a>
+If you want to use <code>xml_node</code> or <code>xml_attribute</code> objects as keys in hash-based associative containers, you can use the <code>hash_value</code> member functions. They return the hash values that are guaranteed to be the same for all handles to the same underlying object. The hash value for null handles is 0.</p>

+<p><a id="xml_attribute::unspecified_bool_type"></a><a id="xml_node::unspecified_bool_type"></a><a id="xml_attribute::empty"></a><a id="xml_node::empty"></a>
+Finally handles can be implicitly cast to boolean-like objects, so that you can test if the node/attribute is empty with the following code: <code>if (node) { &#8230;&#8203; }</code> or <code>if (!node) { &#8230;&#8203; } else { &#8230;&#8203; }</code>. Alternatively you can check if a given <code>xml_node</code>/<code>xml_attribute</code> handle is null by calling the following methods:</p>

+<p>Nodes and attributes do not exist without a document tree, so you can&#8217;t create them without adding them to some document. Once underlying node/attribute objects are destroyed, the handles to those objects become invalid. While this means that destruction of the entire tree invalidates all node/attribute handles, it also means that destroying a subtree (by calling <a href="#xml_node::remove_child">xml_node::remove_child</a>) or removing an attribute invalidates the corresponding handles. There is no way to check handle validity; you have to ensure correctness through external mechanisms.</p>

Because of the scheme specifics, the pages are only destroyed if all objects inside them are destroyed; also, generally destroying an object does not mean that subsequent object creation will reuse the same memory. This means that it is possible to devise a usage scheme which will lead to higher memory usage than expected; one example is adding a lot of nodes, and them removing all even numbered ones; not a single page is reclaimed in the process. However this is an example specifically crafted to produce unsatisfying behavior; in all practical usage scenarios the memory consumption is less than that of a general-purpose allocator because allocation meta-data is very small in size.</p>

+<div class="sectionbody">
+<div class="paragraph">
+<p>pugixml provides several functions for loading XML data from various places - files, C&#43;&#43; iostreams, memory buffers. All functions use an extremely fast non-validating parser. This parser is not fully W3C conformant - it can load any valid XML document, but does not perform some well-formedness checks. While considerable effort is made to reject invalid XML documents, some validation is not performed for performance reasons. Also some XML transformations (i.e. EOL handling or attribute value normalization) can impact parsing speed and thus can be disabled. However for vast majority of XML documents there is no performance difference between different parsing options. Parsing options also control whether certain XML nodes are parsed; see <a href="#loading.options">Parsing options</a> for more information.</p>
+</div>
+<div class="paragraph">
+<p>XML data is always converted to internal character format (see <a href="#dom.unicode">Unicode interface</a>) before parsing. pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it&#8217;s a strict subset of UTF-16) and handles all encoding conversions automatically. Unless explicit encoding is specified, loading functions perform automatic encoding detection based on first few characters of XML data, so in almost all cases you do not have to specify document encoding. Encoding conversion is described in more detail in <a href="#loading.encoding">Encodings</a>.</p>

+Sometimes XML data should be loaded from some other source than a file, i.e. HTTP URL; also you may want to load XML data from file using non-standard functions, i.e. to use your virtual file system facilities or to load XML from GZip-compressed files. All these scenarios require loading document from memory. First you should prepare a contiguous memory block with all XML data; then you have to invoke one of buffer loading functions. These functions will handle the necessary encoding conversions, if any, and then will parse the data into the corresponding XML tree.

Many text editors support 'Go To Position' feature - you can use it to locate the exact error position.

For example, after parsing XML string <code>&lt;node&gt; &lt;a/&gt; &lt;/node&gt;</code>, <code>&lt;node&gt;</code> element will have three children when <code>parse_ws_pcdata</code> is set (child with type <a href="#node_pcdata">node_pcdata</a> and value <code>" "</code>, child with type <a href="#node_element">node_element</a> and name <code>"a"</code>, and another child with type <a href="#node_pcdata">node_pcdata</a> and value <code>" "</code>), and only one child when <code>parse_ws_pcdata</code> is not set.

It is possible to use <a href="#parse_ws_pcdata">parse_ws_pcdata</a> flag in this case, but it results in excessive allocations and complicates document processing; this flag can be used to avoid that. As an example, after parsing XML string <code>&lt;node&gt; &lt;a&gt;  &lt;/a&gt; &lt;/node&gt;</code> with <code>parse_ws_pcdata_single</code> flag set, <code>&lt;node&gt;</code> element will have one child <code>&lt;a&gt;</code>, and <code>&lt;a&gt;</code> element will have one child with type <a href="#node_pcdata">node_pcdata</a> and value <code>"  "</code>.

If node has no children, both functions return null nodes. <code>next_sibling</code> and <code>previous_sibling</code> return the node that&#8217;s immediately to the right/left of this node in the children list, respectively - for example, in <code>&lt;a/&gt;&lt;b/&gt;&lt;c/&gt;</code>, calling <code>next_sibling</code> for a handle that points to <code>&lt;b/&gt;</code> results in a handle pointing to <code>&lt;c/&gt;</code>, and calling <code>previous_sibling</code> results in handle pointing to <code>&lt;a/&gt;</code>. If node does not have next/previous sibling (this happens if it is the last/first node in the list, respectively), the functions return null nodes. <code>first_attribute</code>, <code>last_attribute</code>, <code>next_attribute</code> and <code>previous_attribute</code> functions behave similarly to the corresponding child node functions and allow to iterate through attribute list in the same way.</p>

Past-the-end iterator is commonly used as a termination value for iteration loops (see sample below). If you want to get an iterator that points to an existing handle, you can construct the iterator with the handle as a single constructor argument, like so: <code>xml_node_iterator(node)</code>. For <code>xml_attribute_iterator</code>, you&#8217;ll have to provide both an attribute and its parent node.</p>

+<p>Node paths consist of node names, separated with a delimiter (which is <code>/</code> by default); also paths can contain self (<code>.</code>) and parent (<code>..</code>) pseudo-names, so that this is a valid path: <code>"../../foo/./bar"</code>. <code>path</code> returns the path to the node from the document root, <code>first_element_by_path</code> looks for a node represented by a given path; a path can be an absolute one (absolute paths start with the delimiter), in which case the rest of the path is treated as document root relative, and relative to the given node. For example, in the following document: <code>&lt;a&gt;&lt;b&gt;&lt;c/&gt;&lt;/b&gt;&lt;/a&gt;</code>, node <code>&lt;c/&gt;</code> has path <code>"a/b/c"</code>; calling <code>first_element_by_path</code> for document with path <code>"a/b"</code> results in node <code>&lt;b/&gt;</code>; calling <code>first_element_by_path</code> for node <code>&lt;a/&gt;</code> with path <code>"../a/./b/../."</code> results in node <code>&lt;a/&gt;</code>; calling <code>first_element_by_path</code> with path <code>"/a"</code> results in node <code>&lt;a/&gt;</code> for any node.</p>

+<div class="sectionbody">
+<div class="paragraph">
+<p>The document in pugixml is fully mutable: you can completely change the document structure and modify the data of nodes/attributes. This section provides documentation for the relevant functions. All functions take care of memory management and structural integrity themselves, so they always result in structurally valid tree - however, it is possible to create an invalid XML tree (for example, by adding two attributes with the same name or by setting attribute/node name to empty/invalid string). Tree modification is optimized for performance and for memory consumption, so if you have enough memory you can create documents from scratch with pugixml and later save them to file/stream instead of relying on error-prone manual text writing and without too much overhead.</p>
+</div>
+<div class="paragraph">
+<p>All member functions that change node/attribute data or structure are non-constant and thus can not be called on constant handles. However, you can easily convert constant handle to non-constant one by simple assignment: <code>void foo(const pugi::xml_node&amp; n) { pugi::xml_node nc = n; }</code>, so const-correctness here mainly provides additional documentation.</p>

+With the help of previously described functions, it is possible to create trees with any contents and structure, including cloning the existing data. However since this is an often needed operation, pugixml provides built-in node/attribute cloning facilities. Since nodes and attributes do not exist without a document tree, you can&#8217;t create a standalone copy - you have to immediately insert it somewhere in the tree. For this, you can use one of the following functions:</p>

The functions return the handle to the resulting duplicate object, or null handle on failure.</p>

+Sometimes instead of cloning a node you need to move an existing node to a different position in a tree. This can be accomplished by copying the node and removing the original; however, this is expensive since it results in a lot of extra operations.

+<p>The first method is more convenient, but slower than the other two. The relative performance of <code>append_copy</code> and <code>append_buffer</code> depends on the buffer format - usually <code>append_buffer</code> is faster if the buffer is in native encoding (UTF-8 or wchar_t, depending on <code>PUGIXML_WCHAR_MODE</code>). At the same time it might be less efficient in terms of memory usage - the implementation makes a copy of the provided buffer, and the copy has the same lifetime as the document - the memory used by that copy will be reclaimed after the document is destroyed, but no sooner. Even deleting all nodes in the document, including the appended ones, won&#8217;t reclaim the memory.</p>
+</div>
+<div class="paragraph">
+<p><code>append_buffer</code> behaves in the same way as <a href="#xml_document::load_buffer">xml_document::load_buffer</a> - the input buffer is a byte buffer, with size in bytes; the buffer is not modified and can be freed after the function returns.</p>

+<div class="sectionbody">
+<div class="paragraph">
+<p>Often after creating a new document or loading the existing one and processing it, it is necessary to save the result back to file. Also it is occasionally useful to output the whole document or a subtree to some stream; use cases include debug printing, serialization via network or other text-oriented medium, etc. pugixml provides several functions to output any subtree of the document to a file, stream or another generic transport interface; these functions allow to customize the output format (see <a href="#saving.options">Output options</a>), and also perform necessary encoding conversions (see <a href="#saving.encoding">Encodings</a>). This section documents the relevant functionality.</p>
+</div>
+<div class="paragraph">
+<p>Before writing to the destination the node/attribute data is properly formatted according to the node type; all special XML symbols, such as <code>&lt;</code> and <code>&amp;</code>, are properly escaped (unless <a href="#format_no_escapes">format_no_escapes</a> flag is set). In order to guard against forgotten node/attribute names, empty node/attribute names are printed as <code>":anonymous"</code>. For well-formed output, make sure all node and attribute names are set to meaningful values.</p>

+<div class="paragraph">
+<p>CDATA sections with values that contain <code>"]]&gt;"</code> are split into several sections as follows: section with value <code>"pre]]&gt;post"</code> is written as <code>&lt;![CDATA[pre]]]]&gt;&lt;![CDATA[&gt;post]]&gt;</code>. While this alters the structure of the document (if you load the document after saving it, there will be two CDATA sections instead of one), this is the only way to escape CDATA contents.</p>

If this flag is on, before every node the indentation string is output several times, where the amount of indentation depends on the node&#8217;s depth relative to the output subtree.

If this flag is on, the nodes are not indented in any way, and also no newlines that are not part of document text are printed. Raw mode can be used for serialization where the result is not intended to be read by humans; also it can be useful if the document was parsed with <a href="#parse_ws_pcdata">parse_ws_pcdata</a> flag, to preserve the original document formatting as much as possible.

If this flag is off, special symbols (<code>"</code>, <code>&amp;</code>, <code>&lt;</code>, <code>&gt;</code>) and all non-printable characters (those with codepoint values less than 32) are converted to XML escape sequences (i.e. <code>&amp;amp;</code>) during output. If this flag is on, no text processing is performed; therefore, output XML can be malformed if output contents contains invalid symbols (i.e. having a stray <code>&lt;</code> in the PCDATA will make the output malformed).

By default, if the document is saved via <code>save</code> or <code>save_file</code> function, and it does not have any document declaration, a default declaration is output before the document contents. Enabling this flag disables this declaration. This flag has no effect in <code>xml_node::print</code> functions: they never output the default declaration.

+<p><a id="format_write_bom"></a><code>format_write_bom</code> enables Byte Order Mark (BOM) output. By default, no BOM is output, so in case of non UTF-8 encodings the resulting document&#8217;s encoding may not be recognized by some parsers and text editors, if they do not implement sophisticated encoding detection. Enabling this flag adds an encoding-specific BOM to the output. This flag has no effect in <code>xml_node::print</code> functions: they never output the BOM. This flag is <strong>off</strong> by default.</p>
+</li>
+<li>
+<p><a id="format_save_file_text"></a><code>format_save_file_text</code> changes the file mode when using <code>save_file</code> function. By default, file is opened in binary mode, which means that the output file will
+contain platform-independent newline <code>\n</code> (ASCII 10). If this flag is on, file is opened in text mode, which on some systems changes the newline format (i.e. on Windows you can use this flag to output XML documents with <code>\r\n</code> (ASCII 13 10) newlines.

+<div class="sectionbody">
+<div class="paragraph">
+<p>If the task at hand is to select a subset of document nodes that match some criteria, it is possible to code a function using the existing traversal functionality for any practical criteria. However, often either a data-driven approach is desirable, in case the criteria are not predefined and come from a file, or it is inconvenient to use traversal interfaces and a higher-level DSL is required. There is a standard language for XML processing, XPath, that can be useful for these cases. pugixml implements an almost complete subset of XPath 1.0. Because of differences in document object model and some performance implications, there are minor violations of the official specifications, which can be found in <a href="#xpath.w3c">Conformance to W3C specification</a>. The rest of this section describes the interface for XPath functionality. Please note that if you wish to learn to use XPath language, you have to look for other tutorials or manuals; for example, you can read <a href="http://www.w3schools.com/xpath/">W3Schools XPath tutorial</a>, <a href="http://www.tizag.com/xmlTutorial/xpathtutorial.php">XPath tutorial at tizag.com</a>, and <a href="http://www.w3.org/TR/xpath/">the XPath 1.0 specification</a>.</p>

+Each XPath expression can have one of the following types: boolean, number, string or node set. Boolean type corresponds to <code>bool</code> type, number type corresponds to <code>double</code> type, string type corresponds to either <code>std::string</code> or <code>std::wstring</code>, depending on whether <a href="#dom.unicode">wide character interface is enabled</a>, and node set corresponds to <a href="#xpath_node_set">xpath_node_set</a> type. There is an enumeration, <code>xpath_value_type</code>, which can take the values <code>xpath_type_boolean</code>, <code>xpath_type_number</code>, <code>xpath_type_string</code> or <code>xpath_type_node_set</code>, accordingly.</p>

+<p><a id="xpath_node"></a><a id="xpath_node::node"></a><a id="xpath_node::attribute"></a><a id="xpath_node::parent"></a>
+Because an XPath node can be either a node or an attribute, there is a special type, <code>xpath_node</code>, which is a discriminated union of these types. A value of this type contains two node handles, one of <code>xml_node</code> type, and another one of <code>xml_attribute</code> type; at most one of them can be non-null. The accessors to get these handles are available:</p>

+<p>You can also create XPath nodes with one of the three constructors: the default constructor, the constructor that takes node argument, and the constructor that takes attribute and node arguments (in which case the attribute must belong to the attribute list of the node). The constructor from <code>xml_node</code> is implicit, so you can usually pass <code>xml_node</code> to functions that expect <code>xpath_node</code>. Apart from that you usually don&#8217;t need to create your own XPath node objects, since they are returned to you via selection functions.</p>
+</div>
+<div id="xpath_node_set" class="paragraph">
+<p>XPath expressions operate not on single nodes, but instead on node sets. A node set is a collection of nodes, which can be optionally ordered in either a forward document order or a reverse one. Document order is defined in XPath specification; an XPath node is before another node in document order if it appears before it in XML representation of the corresponding document.</p>

+<div class="paragraph">
+<p>There are two different mechanisms for error handling in XPath implementation; the mechanism used depends on whether exception support is disabled (this is controlled with <a href="#PUGIXML_NO_EXCEPTIONS">PUGIXML_NO_EXCEPTIONS</a> define).</p>
+</div>
+<div class="paragraph">
+<p><a id="xpath_exception"></a><a id="xpath_exception::result"></a><a id="xpath_exception::what"></a>
+By default, XPath functions throw <code>xpath_exception</code> object in case of errors; additionally, in the event any memory allocation fails, an <code>std::bad_alloc</code> exception is thrown. Also <code>xpath_exception</code> is thrown if the query is evaluated to a node set, but the return type is not node set. If the query constructor succeeds (i.e. no exception is thrown), the query object is valid. Otherwise you can get the error details via one of the following functions:</p>

+If exceptions are disabled, then in the event of parsing failure the query is initialized to invalid state; you can test if the query object is valid by using it in a boolean expression: <code>if (query) { &#8230;&#8203; }</code>. Additionally, you can get parsing result via the result() accessor:</p>

+<div class="paragraph">
+<p>Because of the differences in document object models, performance considerations and implementation complexity, pugixml does not provide a fully conformant XPath 1.0 implementation. This is the current list of incompatibilities:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>Consecutive text nodes sharing the same parent are not merged, i.e. in <code>&lt;node&gt;text1 &lt;![CDATA[data]]&gt; text2&lt;/node&gt;</code> node should have one text node child, but instead has three.</p>
+</li>
+<li>
+<p>Since the document type declaration is not used for parsing, <code>id()</code> function always returns an empty node set.</p>
+</li>
+<li>
+<p>Namespace nodes are not supported (affects <code>namespace::</code> axis).</p>
+</li>
+<li>
+<p>Name tests are performed on QNames in XML document instead of expanded names; for <code>&lt;foo xmlns:ns1='uri' xmlns:ns2='uri'&gt;&lt;ns1:child/&gt;&lt;ns2:child/&gt;&lt;/foo&gt;</code>, query <code>foo/ns1:*</code> will return only the first child, not both of them. Compliant XPath implementations can return both nodes if the user provides appropriate namespace declarations.</p>
+</li>
+<li>
+<p>String functions consider a character to be either a single <code>char</code> value or a single <code>wchar_t</code> value, depending on the library configuration; this means that some string functions are not fully Unicode-aware. This affects <code>substring()</code>, <code>string-length()</code> and <code>translate()</code> functions.</p>

+<div class="ulist">
+<ul>
+<li>
+<p>Bug fixes:</p>
+<div class="olist arabic">
+<ol class="arabic">
+<li>
+<p>Documentation fix in samples for <code>parse()</code> with manual lifetime control</p>
+</li>
+<li>
+<p>Fixed document order sorting in XPath (it caused wrong order of nodes after <code>xpath_node_set::sort</code> and wrong results of some XPath queries)</p>
+</li>
+</ol>
+</div>
+</li>
+<li>
+<p>Node printing changes:</p>
+<div class="olist arabic">
+<ol class="arabic">
+<li>
+<p>Single quotes are no longer escaped when printing nodes</p>
+</li>
+<li>
+<p>Symbols in second half of ASCII table are no longer escaped when printing nodes; because of this, <code>format_utf8</code> flag is deleted as it&#8217;s no longer needed and <code>format_write_bom</code> is renamed to <code>format_write_bom_utf8</code>.</p>
+</li>
+<li>
+<p>Reworked node printing - now it works via <code>xml_writer</code> interface; implementations for <code>FILE*</code> and <code>std::ostream</code> are available. As a side-effect, <code>xml_document::save_file</code> now works without STL.</p>
+</li>
+</ol>
+</div>
+</li>
+<li>
+<p>New features:</p>
+<div class="olist arabic">
+<ol class="arabic">
+<li>
+<p>Added unsigned integer support for attributes (<code>xml_attribute::as_uint</code>, <code>xml_attribute::operator=</code>)</p>
+</li>
+<li>
+<p>Now document declaration (<code>&lt;?xml &#8230;&#8203;?&gt;</code>) is parsed as node with type <code>node_declaration</code> when <code>parse_declaration</code> flag is specified (access to encoding/version is performed as if they were attributes, i.e. <code>doc.child("xml").attribute("version").as_float()</code>); corresponding flags for node printing were also added</p>
+</li>
+<li>
+<p>Added support for custom memory management (see <code>set_memory_management_functions</code> for details)</p>
+</li>
+<li>
+<p>Implemented node/attribute copying (see <code>xml_node::insert_copy_*</code> and <code>xml_node::append_copy</code> for details)</p>
+</li>
+<li>
+<p>Added <code>find_child_by_attribute</code> and <code>find_child_by_attribute_w</code> to simplify parsing code in some cases (i.e. COLLADA files)</p>
+</li>
+<li>
+<p>Added file offset information querying for debugging purposes (now you&#8217;re able to determine exact location of any <code>xml_node</code> in parsed file, see <code>xml_node::offset_debug</code> for details)</p>
+</li>
+<li>
+<p>Improved error handling for parsing - now <code>load()</code>, <code>load_file()</code> and <code>parse()</code> return <code>xml_parse_result</code>, which contains error code and last parsed offset; this does not break old interface as <code>xml_parse_result</code> can be implicitly casted to <code>bool</code>.</p>

+<div class="sectionbody">
+<div class="paragraph">
+<p><a href="http://pugixml.org/">pugixml</a> is a light-weight C&#43;&#43; XML processing library. It consists of a DOM-like interface with rich traversal/modification capabilities, an extremely fast XML parser which constructs the DOM tree from an XML file/buffer, and an XPath 1.0 implementation for complex data-driven tree queries. Full Unicode support is also available, with two Unicode interface variants and conversions between different Unicode encodings (which happen automatically during parsing/saving). The library is extremely portable and easy to integrate and use. pugixml is developed and maintained since 2006 and has many users. All code is distributed under the <a href="#license">MIT license</a>, making it completely free to use in both open-source and proprietary applications.</p>
+</div>
+<div class="paragraph">
+<p>pugixml enables very fast, convenient and memory-efficient XML document processing. However, since pugixml has a DOM parser, it can&#8217;t process XML documents that do not fit in memory; also the parser is a non-validating one, so if you need DTD/Schema validation, the library is not for you.</p>
+</div>
+<div class="paragraph">
+<p>This is the quick start guide for pugixml, which purpose is to enable you to start using the library quickly. Many important library features are either not described at all or only mentioned briefly; for more complete information you <a href="manual.html">should read the complete manual</a>.</p>

+<div class="sectionbody">
+<div class="paragraph">
+<p>You can download the latest source distribution as an archive:</p>
+</div>
+<div class="paragraph">
+<p><a href="https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.zip">pugixml-1.6.zip</a> (Windows line endings)
+/
+<a href="https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.tar.gz">pugixml-1.6.tar.gz</a> (Unix line endings)</p>
+</div>
+<div class="paragraph">
+<p>The distribution contains library source, documentation (the guide you&#8217;re reading now and the manual) and some code examples. After downloading the distribution, install pugixml by extracting all files from the compressed archive.</p>
+</div>
+<div class="paragraph">
+<p>The complete pugixml source consists of three files - one source file, <code>pugixml.cpp</code>, and two header files, <code>pugixml.hpp</code> and <code>pugiconfig.hpp</code>. <code>pugixml.hpp</code> is the primary header which you need to include in order to use pugixml classes/functions. The rest of this guide assumes that <code>pugixml.hpp</code> is either in the current directory or in one of include directories of your projects, so that <code>#include "pugixml.hpp"</code> can find the header; however you can also use relative path (i.e. <code>#include "../libs/pugixml/src/pugixml.hpp"</code>) or include directory-relative path (i.e. <code>#include &lt;xml/thirdparty/pugixml/src/pugixml.hpp&gt;</code>).</p>
+</div>
+<div class="paragraph">
+<p>The easiest way to build pugixml is to compile the source file, <code>pugixml.cpp</code>, along with the existing library/executable. This process depends on the method of building your application; for example, if you&#8217;re using Microsoft Visual Studio <span class="footnote">[<a id="_footnoteref_1" class="footnote" href="#_footnote_1" title="View footnote.">1</a>]</span>, Apple Xcode, Code::Blocks or any other IDE, just add <code>pugixml.cpp</code> to one of your projects. There are other building methods available, including building pugixml as a standalone static/shared library; <a href="manual/install.html#install.building">read the manual</a> for further information.</p>
+</div>
+</div>

+<div class="sect1">
+<h2 id="dom"><a class="anchor" href="#dom"></a>Document object model</h2>
+<div class="sectionbody">
+<div class="paragraph">
+<p>pugixml stores XML data in DOM-like way: the entire XML document (both document structure and element data) is stored in memory as a tree. The tree can be loaded from character stream (file, string, C&#43;&#43; I/O stream), then traversed via special API or XPath expressions. The whole tree is mutable: both node structure and node/attribute data can be changed at any time. Finally, the result of document transformations can be saved to a character stream (file, C&#43;&#43; I/O stream or custom transport).</p>
+</div>
+<div class="paragraph">
+<p>The root of the tree is the document itself, which corresponds to C&#43;&#43; type <code>xml_document</code>. Document has one or more child nodes, which correspond to C&#43;&#43; type <code>xml_node</code>. Nodes have different types; depending on a type, a node can have a collection of child nodes, a collection of attributes, which correspond to C&#43;&#43; type <code>xml_attribute</code>, and some additional data (i.e. name).</p>
+</div>
+<div class="paragraph">
+<p>The most common node types are:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>Document node (<code>node_document</code>) - this is the root of the tree, which consists of several child nodes. This node corresponds to <code>xml_document</code> class; note that <code>xml_document</code> is a sub-class of <code>xml_node</code>, so the entire node interface is also available.</p>
+</li>
+<li>
+<p>Element/tag node (<code>node_element</code>) - this is the most common type of node, which represents XML elements. Element nodes have a name, a collection of attributes and a collection of child nodes (both of which may be empty). The attribute is a simple name/value pair.</p>
+</li>
+<li>
+<p>Plain character data nodes (<code>node_pcdata</code>) represent plain text in XML. PCDATA nodes have a value, but do not have name or children/attributes. Note that <strong>plain character data is not a part of the element node but instead has its own node</strong>; for example, an element node can have several child PCDATA nodes.</p>
+</li>
+</ul>
+</div>
+<div class="paragraph">
+<p>Despite the fact that there are several node types, there are only three C&#43;&#43; types representing the tree (<code>xml_document</code>, <code>xml_node</code>, <code>xml_attribute</code>); some operations on <code>xml_node</code> are only valid for certain node types. They are described below.</p>

+<td class="content">
+All pugixml classes and functions are located in <code>pugi</code> namespace; you have to either use explicit name qualification (i.e. <code>pugi::xml_node</code>), or to gain access to relevant symbols via <code>using</code> directive (i.e. <code>using pugi::xml_node;</code> or <code>using namespace pugi;</code>).
+</td>
+</tr>
+</table>
+</div>
+<div class="paragraph">
+<p><code>xml_document</code> is the owner of the entire document structure; destroying the document destroys the whole tree. The interface of <code>xml_document</code> consists of loading functions, saving functions and the entire interface of <code>xml_node</code>, which allows for document inspection and/or modification. Note that while <code>xml_document</code> is a sub-class of <code>xml_node</code>, <code>xml_node</code> is not a polymorphic type; the inheritance is present only to simplify usage.</p>
+</div>
+<div class="paragraph">
+<p><code>xml_node</code> is the handle to document node; it can point to any node in the document, including document itself. There is a common interface for nodes of all types. Note that <code>xml_node</code> is only a handle to the actual node, not the node itself - you can have several <code>xml_node</code> handles pointing to the same underlying object. Destroying <code>xml_node</code> handle does not destroy the node and does not remove it from the tree.</p>
+</div>
+<div class="paragraph">
+<p>There is a special value of <code>xml_node</code> type, known as null node or empty node. It does not correspond to any node in any document, and thus resembles null pointer. However, all operations are defined on empty nodes; generally the operations don&#8217;t do anything and return empty nodes/attributes or empty strings as their result. This is useful for chaining calls; i.e. you can get the grandparent of a node like so: <code>node.parent().parent()</code>; if a node is a null node or it does not have a parent, the first <code>parent()</code> call returns null node; the second <code>parent()</code> call then also returns null node, so you don&#8217;t have to check for errors twice. You can test if a handle is null via implicit boolean cast: <code>if (node) { &#8230;&#8203; }</code> or <code>if (!node) { &#8230;&#8203; }</code>.</p>
+</div>
+<div class="paragraph">
+<p><code>xml_attribute</code> is the handle to an XML attribute; it has the same semantics as <code>xml_node</code>, i.e. there can be several <code>xml_attribute</code> handles pointing to the same underlying object and there is a special null attribute value, which propagates to function results.</p>
+</div>
+<div class="paragraph">
+<p>There are two choices of interface and internal representation when configuring pugixml: you can either choose the UTF-8 (also called char) interface or UTF-16/32 (also called wchar_t) one. The choice is controlled via <code>PUGIXML_WCHAR_MODE</code> define; you can set it via <code>pugiconfig.hpp</code> or via preprocessor options. All tree functions that work with strings work with either C-style null terminated strings or STL strings of the selected character type. <a href="manual/dom.html#dom.unicode">Read the manual</a> for additional information on Unicode interface.</p>

+<h2 id="loading"><a class="anchor" href="#loading"></a>Loading document</h2>
+<div class="sectionbody">
+<div class="paragraph">
+<p>pugixml provides several functions for loading XML data from various places - files, C&#43;&#43; iostreams, memory buffers. All functions use an extremely fast non-validating parser. This parser is not fully W3C conformant - it can load any valid XML document, but does not perform some well-formedness checks. While considerable effort is made to reject invalid XML documents, some validation is not performed because of performance reasons. XML data is always converted to internal character format before parsing. pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it&#8217;s a strict subset of UTF-16) and handles all encoding conversions automatically.</p>
+</div>
+<div class="paragraph">
+<p>The most common source of XML data is files; pugixml provides a separate function for loading XML document from file. This function accepts file path as its first argument, and also two optional arguments, which specify parsing options and input data encoding, which are described in the manual.</p>

+<p>Sometimes XML data should be loaded from some other source than file, i.e. HTTP URL; also you may want to load XML data from file using non-standard functions, i.e. to use your virtual file system facilities or to load XML from gzip-compressed files. These scenarios either require loading document from memory, in which case you should prepare a contiguous memory block with all XML data and to pass it to one of buffer loading functions, or loading document from C&#43;&#43; IOstream, in which case you should provide an object which implements <code>std::istream</code> or <code>std::wistream</code> interface.</p>

+<div class="sectionbody">
+<div class="paragraph">
+<p>pugixml features an extensive interface for getting various types of data from the document and for traversing the document. You can use various accessors to get node/attribute data, you can traverse the child node/attribute lists via accessors or iterators, you can do depth-first traversals with <code>xml_tree_walker</code> objects, and you can use XPath for complex data-driven queries.</p>
+</div>
+<div class="paragraph">
+<p>You can get node or attribute name via <code>name()</code> accessor, and value via <code>value()</code> accessor. Note that both functions never return null pointers - they either return a string with the relevant content, or an empty string if name/value is absent or if the handle is null. Also there are two notable things for reading values:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>It is common to store data as text contents of some node - i.e. <code>&lt;node&gt;&lt;description&gt;This is a node&lt;/description&gt;&lt;/node&gt;</code>. In this case, <code>&lt;description&gt;</code> node does not have a value, but instead has a child of type <code>node_pcdata</code> with value <code>"This is a node"</code>. pugixml provides <code>child_value()</code> and <code>text()</code> helper functions to parse such data.</p>
+</li>
+<li>
+<p>In many cases attribute values have types that are not strings - i.e. an attribute may always contain values that should be treated as integers, despite the fact that they are represented as strings in XML. pugixml provides several accessors that convert attribute value to some other type.</p>

+<p>The document in pugixml is fully mutable: you can completely change the document structure and modify the data of nodes/attributes. All functions take care of memory management and structural integrity themselves, so they always result in structurally valid tree - however, it is possible to create an invalid XML tree (for example, by adding two attributes with the same name or by setting attribute/node name to empty/invalid string). Tree modification is optimized for performance and for memory consumption, so if you have enough memory you can create documents from scratch with pugixml and later save them to file/stream instead of relying on error-prone manual text writing and without too much overhead.</p>
+</div>
+<div class="paragraph">
+<p>All member functions that change node/attribute data or structure are non-constant and thus can not be called on constant handles. However, you can easily convert constant handle to non-constant one by simple assignment: <code>void foo(const pugi::xml_node&amp; n) { pugi::xml_node nc = n; }</code>, so const-correctness here mainly provides additional documentation.</p>
+</div>
+<div class="paragraph">
+<p>As discussed before, nodes can have name and value, both of which are strings. Depending on node type, name or value may be absent. You can use <code>set_name</code> and <code>set_value</code> member functions to set them. Similar functions are available for attributes; however, the <code>set_value</code> function is overloaded for some other types except strings, like floating-point numbers. Also, attribute value can be set using an assignment operator. This is an example of setting node/attribute name and value (<a href="samples/modify_base.cpp" class="bare">samples/modify_base.cpp</a>):</p>

+<div class="sectionbody">
+<div class="paragraph">
+<p>Often after creating a new document or loading the existing one and processing it, it is necessary to save the result back to file. Also it is occasionally useful to output the whole document or a subtree to some stream; use cases include debug printing, serialization via network or other text-oriented medium, etc. pugixml provides several functions to output any subtree of the document to a file, stream or another generic transport interface; these functions allow to customize the output format, and also perform necessary encoding conversions.</p>
+</div>
+<div class="paragraph">
+<p>Before writing to the destination the node/attribute data is properly formatted according to the node type; all special XML symbols, such as &lt; and &amp;, are properly escaped. In order to guard against forgotten node/attribute names, empty node/attribute names are printed as <code>":anonymous"</code>. For well-formed output, make sure all node and attribute names are set to meaningful values.</p>
+</div>
+<div class="paragraph">
+<p>If you want to save the whole document to a file, you can use the <code>save_file</code> function, which returns <code>true</code> on success. This is a simple example of saving XML document to file (<a href="samples/save_file.cpp" class="bare">samples/save_file.cpp</a>):</p>

+<div class="paragraph">
+<p>To enhance interoperability pugixml provides functions for saving document to any object which implements C&#43;&#43; <code>std::ostream</code> interface. This allows you to save documents to any standard C&#43;&#43; stream (i.e. file stream) or any third-party compliant implementation (i.e. Boost Iostreams). Most notably, this allows for easy debug output, since you can use <code>std::cout</code> stream as saving target. There are two functions, one works with narrow character streams, another handles wide character ones.</p>

+</div>
+</div>
+<div class="paragraph">
+<p>All of the above saving functions are implemented in terms of writer interface. This is a simple interface with a single function, which is called several times during output process with chunks of document data as input. In order to output the document via some custom transport, for example sockets, you should create an object which implements <code>xml_writer_file</code> interface and pass it to <code>xml_document::save</code> function.</p>

+</div>
+</div>
+<div class="paragraph">
+<p>While the previously described functions save the whole document to the destination, it is easy to save a single subtree. Instead of calling <code>xml_document::save</code>, just call <code>xml_node::print</code> function on the target node. You can save node contents to C&#43;&#43; IOstream object or custom writer in this way. Saving a subtree slightly differs from saving the whole document; <a href="manual/saving.html#saving.subtree">read the manual</a> for more information.</p>
