<div class="textblock"><p>Implements the interface to the "Visitor pattern" (see the Accept() method.) If you call the Accept() method, it requires being passed a <a class="el" href="classtinyxml2_1_1_x_m_l_visitor.html">XMLVisitor</a> class to handle callbacks. For nodes that contain other nodes (Document, Element) you will get called with a VisitEnter/VisitExit pair. Nodes that are always leafs are simply called with <a class="el" href="classtinyxml2_1_1_x_m_l_visitor.html#adc75bd459fc7ba8223b50f0616767f9a" title="Visit a declaration. ">Visit()</a>.</p>
|
|
<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 siblings</b> will be visited.</p>
|
|
<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>
|
|
<p>Generally Accept() is called on the <a class="el" href="classtinyxml2_1_1_x_m_l_document.html">XMLDocument</a>, although all nodes support visiting.</p>
|
|
<p>You should never change the document from a callback.</p>
