href="classTiXmlVisitor.html">TiXmlVisitor</a> class to handle callbacks. <p>For nodes that contain other nodes (Document, Element) you will get called with a VisitEnter/VisitExit pair. Nodes that are always leaves are simple called with <a class="el" href="classTiXmlVisitor.html#fad71c71ce6473fb9b4b64cd92de4a19">Visit()</a>.<p>If you return 'true' from a Visit method, recursive parsing will continue. If you return false, <b>no children of this node or its sibilings</b> will be Visited.<p>All flavors of Visit methods have a default implementation that returns 'true' (continue visiting). You need to only override methods that are interesting to you.<p>Generally Accept() is called on the <a class="el" href="classTiXmlDocument.html">TiXmlDocument</a>, although all nodes suppert Visiting.<p>You should never change the document from a callback.<p><dl compact><dt><b>See also:</b></dt><dd><a class="el" href="classTiXmlNode.html#cc0f88b7462c6cb73809d410a4f5bb86">TiXmlNode::Accept()</a> </dd></dl><p><hr>The documentation for this class was generated from the following file:<ul><li><a class="el" href="tinyxml_8h-source.html">tinyxml.h</a></ul><hr size="1"><address style="align: right;"><small>Generated on Sun May 6 15:41:23 2007 for TinyXml by <a href="http://www.doxygen.org/index.html"><img src="doxygen.png" alt="doxygen" align="middle" border="0"></a> 1.4.7 </small></address></body></html>?? 快捷鍵說明
