+ 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.
