- 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 Visit().
-
- 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.
-
- 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 support visiting.
-
- You should never change the document from a callback.

-
- And that doesn't even cover "else" cases. XMLHandle addresses the verbosity
- of such code. A XMLHandle checks for null pointers so it is perfectly safe
- and correct to use:
-
- @verbatim
- XMLHandle docHandle( &document );
- XMLElement* child2 = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).FirstChild().NextSibling().ToElement();
- if ( child2 )
- {
- // do something useful
- @endverbatim
-
- Which is MUCH more concise and useful.
-
- It is also safe to copy handles - internally they are nothing more than node pointers.
- @verbatim
- XMLHandle handleCopy = handle;
- @endverbatim
-
- See also XMLConstHandle, which is the same as XMLHandle, but operates on const objects.
