+ 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-2
+ 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.FirstChildElement( "Document" ).FirstChildElement( "Element" ).FirstChildElement().NextSiblingElement();
+ 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.
