-/**
- A TiXmlHandle is a class that wraps a node pointer with null checks; this is
- an incredibly useful thing. Note that TiXmlHandle 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
- TiXmlElement* root = document.FirstChildElement( "Document" );
- if ( root )
- {
- TiXmlElement* element = root->FirstChildElement( "Element" );
- if ( element )
- {
- TiXmlElement* child = element->FirstChildElement( "Child" );
- if ( child )
- {
- TiXmlElement* child2 = child->NextSiblingElement( "Child" );
- if ( child2 )
- {
- // Finally do something useful.
- @endverbatim
-
- And that doesn't even cover "else" cases. TiXmlHandle addresses the verbosity
- of such code. A TiXmlHandle checks for null pointers so it is perfectly safe
- and correct to use:
-
- @verbatim
- TiXmlHandle docHandle( &document );
- TiXmlElement* child2 = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).Child( "Child", 1 ).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
- TiXmlHandle handleCopy = handle;
- @endverbatim
-
- What they should not be used for is iteration:
-
- @verbatim
- int i=0;
- while ( true )
- {
- TiXmlElement* child = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).Child( "Child", i ).ToElement();
- if ( !child )
- break;
- // do something
- ++i;
- }
- @endverbatim
-
- It seems reasonable, but it is in fact two embedded while loops. The Child method is
- a linear walk to find the element, so this code would iterate much more than it needs
- to. Instead, prefer:
-
- @verbatim
- TiXmlElement* child = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).FirstChild( "Child" ).ToElement();
-
- for( child; child; child=child->NextSiblingElement() )
- {
- // do something
- }
- @endverbatim
