十分好用的xml文件分析器

Note that this function can be misleading. If the element foo was created from this XML: <div class="fragment"><pre class="fragment">		&lt;foo&gt;&lt;b&gt;This is text&lt;/b&gt;&lt;/foo&gt; 
		</pre></div><p>
then the value of str would be null. The first child node isn't a text node, it is another element. From this XML: <div class="fragment"><pre class="fragment">		&lt;foo&gt;This is &lt;b&gt;text&lt;/b&gt;&lt;/foo&gt; 
		</pre></div> <a class="el" href="classTiXmlElement.html#f3282294986cdb216646ea1f67af2c87">GetText()</a> will return "This is ".<p>
WARNING: <a class="el" href="classTiXmlElement.html#f3282294986cdb216646ea1f67af2c87">GetText()</a> accesses a child node - don't become confused with the similarly named <a class="el" href="classTiXmlHandle.html#9fc739c8a18d160006f82572fc143d13">TiXmlHandle::Text()</a> and <a class="el" href="classTiXmlNode.html#3ddfbcac78fbea041fad57e5c6d60a03">TiXmlNode::ToText()</a> which are safe type casts on the referenced node.

All TinyXml classes can print themselves to a filestream or the string class (TiXmlString in non-STL mode, std::string in STL mode. 
<p>
) Either or both cfile and str can be null.<p>
This is a formatted print, and will insert tabs and newlines.<p>
(For an unformatted stream, use the &lt;&lt; operator.)

QueryIntAttribute examines the attribute - it is an alternative to the <a class="el" href="classTiXmlElement.html#e419a442a9701a62b0c3d8fd1cbdd12d">Attribute()</a> method with richer error checking. 
<p>
If the attribute is an integer, it is stored in 'value' and the call returns TIXML_SUCCESS. If it is not an integer, it returns TIXML_WRONG_TYPE. If the attribute does not exist, then TIXML_NO_ATTRIBUTE is returned.
