TiXmlVisitor¶

class
TiXmlVisitor
¶ Implements the interface to the “Visitor pattern” (see the Accept() method.) If you call the Accept() method, it requires being passed a TiXmlVisitor 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 leaves are simply called with
Visit()
.If you return ‘true’ from a Visit method, recursive parsing will continue. If you return false, no children of this node or its sibilings will be Visited.
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.
Generally Accept() is called on the
TiXmlDocument
, although all nodes suppert Visiting.You should never change the document from a callback.
