|
|
|
+ Implements the interface to the "Visitor pattern" (see the Accept() method.)
|
|
|
+ If you call the Accept() method, it requires being passed a XMLVisitor
|
|
|
+ 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.

|
|
|
+ A XMLHandle is a class that wraps a node pointer with null checks; this is
|
|
|
+ an incredibly useful thing. Note that XMLHandle is not part of the TinyXML
|
|
|
+ DOM structure. It is a separate utility class.
|
|
|
+
|
|
|
+ Take an example:
|
|
|
+ @verbatim
|
|
|
+ <Document>
|
|
|
+ <Element attributeA = "valueA">
|
|
|
+ <Child attributeB = "value1" />
|
|
|
+ <Child attributeB = "value2" />
|
|
|
+ </Element>
|
|
|
+ </Document>
|
|
|
+ @endverbatim
|
|
|
+
|
|
|
+ Assuming you want the value of "attributeB" in the 2nd "Child" element, it's very
|
|
|
+ easy to write a *lot* of code that looks like:
|
|
|
+
|
|
|
+ @verbatim
|
|
|
+ XMLElement* root = document.FirstChildElement( "Document" );
|
|
|
+ if ( root )
|
|
|
+ {
|
|
|
+ XMLElement* element = root->FirstChildElement( "Element" );
|
|
|
+ if ( element )
|
|
|
+ {
|
|
|
+ XMLElement* child = element->FirstChildElement( "Child" );
|
|
|
+ if ( child )
|
|
|
+ {
|
|
|
+ XMLElement* child2 = child->NextSiblingElement( "Child" );
|
|
|
+ if ( child2 )
|
|
|
+ {
|
|
|
+ // Finally do something useful.
|
|
|
+ @endverbatim
|
|
|
+
|
|
|
+ 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.
