+/**\r
+ A XMLHandle is a class that wraps a node pointer with null checks; this is\r
+ an incredibly useful thing. Note that XMLHandle is not part of the TinyXML-2\r
+ DOM structure. It is a separate utility class.\r
+\r
+ Take an example:\r
+ @verbatim\r
+ <Document>\r
+ <Element attributeA = "valueA">\r
+ <Child attributeB = "value1" />\r
+ <Child attributeB = "value2" />\r
+ </Element>\r
+ </Document>\r
+ @endverbatim\r
+\r
+ Assuming you want the value of "attributeB" in the 2nd "Child" element, it's very\r
+ easy to write a *lot* of code that looks like:\r
+\r
+ @verbatim\r
+ XMLElement* root = document.FirstChildElement( "Document" );\r
+ if ( root )\r
+ {\r
+ XMLElement* element = root->FirstChildElement( "Element" );\r
+ if ( element )\r
+ {\r
+ XMLElement* child = element->FirstChildElement( "Child" );\r
+ if ( child )\r
+ {\r
+ XMLElement* child2 = child->NextSiblingElement( "Child" );\r
+ if ( child2 )\r
+ {\r
+ // Finally do something useful.\r
+ @endverbatim\r
+\r
+ And that doesn't even cover "else" cases. XMLHandle addresses the verbosity\r
+ of such code. A XMLHandle checks for null pointers so it is perfectly safe\r
+ and correct to use:\r
+\r
+ @verbatim\r
+ XMLHandle docHandle( &document );\r
+ XMLElement* child2 = docHandle.FirstChildElement( "Document" ).FirstChildElement( "Element" ).FirstChildElement().NextSiblingElement();\r
+ if ( child2 )\r
+ {\r
+ // do something useful\r
+ @endverbatim\r
+\r
+ Which is MUCH more concise and useful.\r
+\r
+ It is also safe to copy handles - internally they are nothing more than node pointers.\r
+ @verbatim\r
+ XMLHandle handleCopy = handle;\r
+ @endverbatim\r
+\r
+ See also XMLConstHandle, which is the same as XMLHandle, but operates on const objects.\r
