+ Given a text object, you can get the contents (i.e. the value of PCDATA/CDATA
+ node) by using the following function:
+ </p>
+<pre class="programlisting"><span class="keyword">const</span> <span class="identifier">char_t</span><span class="special">*</span> <span class="identifier">xml_text</span><span class="special">::</span><span class="identifier">get</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>
+</pre>
+<p>
+ In case text object is empty, the function returns an empty string - it never
+ returns a null pointer.
+ </p>
+<a name="xml_text::as_string"></a><a name="xml_text::as_int"></a><a name="xml_text::as_uint"></a><a name="xml_text::as_double"></a><a name="xml_text::as_float"></a><a name="xml_text::as_bool"></a><p>
+ 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:
+ </p>

+ 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.
+ </p>
+<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 [node_cdata]. You can use the following function to retrieve this node:
+ </p>
+<pre class="programlisting"><span class="identifier">xml_node</span> <span class="identifier">xml_text</span><span class="special">::</span><span class="identifier">data</span><span class="special">()</span> <span class="keyword">const</span><span class="special">;</span>
+</pre>
+<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, callling
+ <code class="computeroutput"><span class="identifier">text</span><span class="special">.</span><span class="identifier">get</span><span class="special">()</span></code> is
+ equivalent to calling <code class="computeroutput"><span class="identifier">text</span><span class="special">.</span><span class="identifier">data</span><span class="special">().</span><span class="identifier">value</span><span class="special">()</span></code>.
+ </p>
+<p>
+ This is an example of using <code class="computeroutput"><span class="identifier">xml_text</span></code>

+<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:

+ </li>

+ pugixml provides a special class, <code class="computeroutput"><span class="identifier">xml_text</span></code>,
+ to work with text contents stored as a value 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>.
+ Working with text objects to retrieve data is described in <a class="link" href="access.html#manual.access.text" title="Working with text contents">the
+ documentation for accessing document data</a>; this section describes
+ the modification interface of <code class="computeroutput"><span class="identifier">xml_text</span></code>.
+ </p>
+<a name="xml_text::set"></a><p>
+ Once you have an <code class="computeroutput"><span class="identifier">xml_text</span></code>
+ object, you can set the text contents using the following function:
+ </p>
+<pre class="programlisting"><span class="keyword">bool</span> <span class="identifier">xml_text</span><span class="special">::</span><span class="identifier">set</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>
+ 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 that 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).
+ </p>
+<a name="xml_text::set_value"></a><p>
+ In addition to a string function, several functions are provided for handling
+ text with numbers and booleans as contents:
+ </p>
+<pre class="programlisting"><span class="keyword">bool</span> <span class="identifier">xml_text</span><span class="special">::</span><span class="identifier">set</span><span class="special">(</span><span class="keyword">int</span> <span class="identifier">rhs</span><span class="special">);</span>

+</pre>
+<p>
+ The above functions convert the argument to string and then call the base
+ <code class="computeroutput"><span class="identifier">set</span></code> function. These functions

pugixml enables very fast, convenient and memory-efficient XML document processing.

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.

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

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:

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, <code class="computeroutput"><span class="identifier">child</span><span class="special">(</span><span class="string">"Tool"</span><span class="special">)</span></code>
returns the first node which has the name <code class="computeroutput"><span class="string">"Tool"</span></code>,

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>

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>

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.
