+<p>
+        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 <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 MIT license, 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 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>.

+<p>
+        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="http://code.google.com/p/pugixml/issues/entry" 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, 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.
+      </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 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.

+      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).

+        return past-the-end iterator for node/attribute list, respectively - this

+        pointing to the last element in the list (except for empty lists, where decrementing
+        past-the-end iterator is not defined). 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.

+        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 <code class="computeroutput"><span class="identifier">node_document</span></code>,
+        which is the root node of the document the node belongs to (unless the node
+        is null, in which case null node is returned). Currently this function has
+        logarithmic complexity, since it simply finds such ancestor of the given
+        node which itself has no parent.
+      </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>

+</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 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.

+        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 <code class="computeroutput"><span class="identifier">pugi</span><span class="special">::</span><span class="identifier">char_t</span></code>
+        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 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 XML document is represented with a tree data structure. 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).

Note that <code class="computeroutput"><span class="identifier">xml_node</span></code>

+        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

+        it possible to use them as keys of 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.

+        Nodes and attributes do not exist outside of document tree, so you can't

+        this means that destruction of the entire tree invalidates all node/attribute
+        handles, it also means that destroying a subtree (by calling <code class="computeroutput"><span class="identifier">remove_child</span></code>) 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 localized, wchar_t mode
+        is probably a better choice.
+      </p>
+<a name="as_utf8"></a><a name="as_wide"></a><p>

+        Both functions accept 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.

+</ul></div>
+<p>
+        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.
+      </p>

+<p>
+        With the exception of XPath, pugixml itself does not throw any exceptions.
+        Additionally, most pugixml functions have a no-throw exception guarantee.
+      </p>
+<p>
+        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. <code class="computeroutput"><span class="identifier">xml_node</span><span class="special">::</span><span class="identifier">traverse</span></code>
+        or <code class="computeroutput"><span class="identifier">xml_node</span><span class="special">::</span><span class="identifier">find_node</span></code>) do not provide any exception
+        guarantees beyond the ones provided by callback.
+      </p>
+<p>
+        XPath functions may throw <code class="computeroutput"><span class="identifier">xpath_exception</span></code>
+        on parsing error; also, XPath implementation uses STL, and thus may throw
+        i.e. <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">bad_alloc</span></code> in low memory conditions. Still,
+        XPath functions provide strong exception guarantee.

+          Allocation function is called with the size (in bytes) as an argument and
+          should return a pointer to memory block with alignment that is suitable
+          for pointer storage and size that is greater 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 the previous call

+        </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 <code class="computeroutput"><span class="identifier">xml_document</span></code> 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

+          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.

+          The Subversion repository is located at <a href="http://pugixml.googlecode.com/svn/" target="_top">http://pugixml.googlecode.com/svn/</a>.
+          There is a Subversion tag "release-{version}" for each version;

+          stable release.
+        </p>
+<p>
+          For example, to checkout the current version, you can use this command:
+        </p>
+<pre class="programlisting">svn checkout http://pugixml.googlecode.com/svn/tags/release-0.9 pugixml</pre>
+<p>
+          To checkout the latest version, you can use this command:

+<p>
+          Use latest version tag if you want to automatically get new versions via

+          new versions only explicitly (for example, using <code class="literal">svn switch</code>
+          command). Also please note that Subversion trunk contains the work-in-progress
+          version of the code; while this means that you can get new features and
+          bug fixes from trunk 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>
+        The complete pugixml source consists of four files - two source files, <code class="filename">pugixml.cpp</code> and
+        <code class="filename">pugixpath.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>

+          The easiest way to build pugixml is to compile two source files, <code class="filename">pugixml.cpp</code> and
+          <code class="filename">pugixpath.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<sup>[<a name="id1323403" href="#ftn.id1323403" class="footnote">1</a>]</sup>, Apple Xcode, Code::Blocks or any other IDE, just add <code class="filename">pugixml.cpp</code> and
+          <code class="filename">pugixpath.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">pugixpath.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> and
+          <code class="filename">pugixpath.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 both <code class="filename">pugixml.cpp</code> and <code class="filename">pugixpath.cpp</code>, for all project configurations/platforms
+          (you can select Configuration "All Configurations" and Platform
+          "All Platforms" before editing the option):

+          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 <code class="computeroutput"><span class="identifier">PUGIXML_API</span></code>
+          macro, i.e. via <code class="filename">pugiconfig.hpp</code>:
+        </p>

+          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. Define consistency is important, i.e. 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 new version,
+          you can safely leave your modified version intact.

+      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. 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>.

+        This function accepts file path as its first argument, and also two optional

+        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 target system, it should have the exact case if target
+        file system is case-sensitive, etc. File path is passed to system file opening
+        function as is.

+        The result of the operation is returned in an <code class="computeroutput"><span class="identifier">xml_parse_result</span></code>
+        object; this object contains the operation status, and the related information
+        (i.e. last successfully parsed position in the input file, if parsing fails).

+        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. 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:

+</pre>
+<p>
+        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:
+      </p>
+<pre class="programlisting"><span class="identifier">xml_parse_result</span> <span class="identifier">xml_document</span><span class="special">::</span><span class="identifier">load</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">char_t</span><span class="special">*</span> <span class="identifier">contents</span><span class="special">,</span> <span class="keyword">unsigned</span> <span class="keyword">int</span> <span class="identifier">options</span> <span class="special">=</span> <span class="identifier">parse_default</span><span class="special">);</span>
+</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> <span class="special">=</span>
+        <span class="identifier">strlen</span><span class="special">(</span><span class="identifier">contents</span><span class="special">)</span></code>.
+        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 buffer loading functions.

+        argument loads the document from stream from the current read position to

+        on an opened <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">ifstream</span></code> object is equivalent to calling

+        Because of this, using <code class="computeroutput"><span class="identifier">load</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>

+        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.
+      </p>
+<p>
+        As for rejecting invalid XML documents, there are a number of incompatibilities
+        with W3C specification, including:

+<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>
+<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>

+        As discussed before, nodes can have name and value, both of which are strings.
+        Depending on node type, name or value may be absent. <code class="computeroutput"><span class="identifier">node_document</span></code>
+        nodes do not have name or value, <code class="computeroutput"><span class="identifier">node_element</span></code>
+        and <code class="computeroutput"><span class="identifier">node_declaration</span></code> nodes
+        always have a name but never have a value, <code class="computeroutput"><span class="identifier">node_pcdata</span></code>,
+        <code class="computeroutput"><span class="identifier">node_cdata</span></code> and <code class="computeroutput"><span class="identifier">node_comment</span></code> nodes never have a name but
+        always have a value (it may be empty though), <code class="computeroutput"><span class="identifier">node_pi</span></code>
+        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 <code class="computeroutput"><span class="identifier">node_pcdata</span></code> 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.
+      </p>
+<p>
+        There is no equivalent of <code class="computeroutput"><span class="identifier">child_value</span></code>
+        function for modifying text children of the node.
+      </p>

+</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" type="disc">
+<li class="listitem">

+</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:
+      </p>

+</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>.

+        With the help of previously described functions, it is possible to create

+        However since this is an often needed operation, pugixml provides built-in
+        node/attribute cloning facilities. Since nodes and attributes do not exist
+        outside of document tree, you can't create a standalone copy - you have to

+      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>
+      The node/attribute data is written to the destination 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 proper output, make sure all node and attribute names are set to meaningful
+      values.

+        stream as saving target. There are two functions, one works with narrow character

+<p>
+        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">save</span></code>
+        function. <code class="computeroutput"><span class="identifier">xml_writer_file</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 first block with BOM, which is output only if <code class="computeroutput"><span class="identifier">format_write_bom</span></code>
+        is set, and last block, which may be small), so there is often no need for
+        additional buffering in the implementation.

+<p>
+        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 <code class="computeroutput"><span class="identifier">format_write_bom</span></code> is
+        off, and <code class="computeroutput"><span class="identifier">format_no_declaration</span></code>
+        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:

+<p>
+        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 <code class="computeroutput"><span class="identifier">encoding_wchar</span></code>
+        encoding.

+          The current behavior for Unicode conversion is to skip all invalid UTF

+          may be output as if they are empty, which will result in malformed XML

+<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>,
+      <a href="http://www.tizag.com/xmlTutorial/xpathtutorial.php" target="_top">XPath tutorial
+      at tizag.com</a>, and <a href="http://www.w3.org/TR/xpath/" target="_top">the XPath

+        Because an XPath node can be either a node or an attribute, there is a special

+        a discriminated union of these types. A value of this type contains two node

+        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:

+<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>

+<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>

+        You can also create XPath nodes with one of tree 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). However, usually you don't need
+        to create your own XPath node objects, since they are returned to you via

+        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.

+        As of version 0.9, all XPath errors result in thrown exceptions. The errors
+        can arise during expression compilation or node set evaluation. In both cases,
+        an <code class="computeroutput"><span class="identifier">xpath_exception</span></code> object
+        is thrown. This is an exception object that implements <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">exception</span></code>
+        interface, and thus has a single function <code class="computeroutput"><span class="identifier">what</span><span class="special">()</span></code>:

+<p>
+        This function returns the error message. Currently it is impossible to get

+<p>
+        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 MIT license, 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="http://pugixml.googlecode.com/files/pugixml-0.9.zip" target="_top">http://pugixml.googlecode.com/files/pugixml-0.9.zip</a>
+<a href="http://pugixml.googlecode.com/files/pugixml-0.9.tar.gz" target="_top">http://pugixml.googlecode.com/files/pugixml-0.9.tar.gz</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.
+      </p>
+<p>
+        The complete pugixml source consists of four files - two source files, <code class="filename">pugixml.cpp</code> and
+        <code class="filename">pugixpath.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 two source files, <code class="filename">pugixml.cpp</code> and
+        <code class="filename">pugixpath.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<sup>[<a name="id1329323" href="#ftn.id1329323" class="footnote">1</a>]</sup>, Apple Xcode, Code::Blocks or any other IDE, just add <code class="filename">pugixml.cpp</code> and
+        <code class="filename">pugixpath.cpp</code> to one of your projects. There are other building methods available,
+        including building pugixml as a standalone static/shared library; read the
+        manual 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" 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 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.
+          </li>
+</ul></div>

+        <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 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 only used 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, 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. Read the manual for additional information
+        on Unicode interface.

+        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.

+        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

+        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:

+<div class="itemizedlist"><ul class="itemizedlist" 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>

+            with value <code class="computeroutput"><span class="string">"This is a node"</span></code>.

+        Since a lot of document traversal consists of finding the node/attribute

+        returns the first node which has the name <code class="computeroutput"><span class="string">"Tool"</span></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

+        to implement <code class="computeroutput"><span class="identifier">xml_tree_walker</span></code>
+        interface and to call <code class="computeroutput"><span class="identifier">traverse</span></code>

+<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>
+<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>):

+        All insertion functions return the handle to newly created object on success,

+<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>
+<p>
+        The node/attribute data is written to the destination 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 proper 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>
+<p>
+        
+</p>
+<pre class="programlisting"><span class="comment">// save document to file

+        For additional 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 <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="special">};</span>
+</pre>
+<p>
+      </p>
+<p>
+        While the previously described functions saved 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; read the manual for more information.
