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 -*/ -class TiXmlHandle -{ -public: - /// Create a handle from any node (at any depth of the tree.)
