* THIS FILE WAS ALTERED BY Tyge Lovset, 7. April 2005.
*
* - completely rewritten. compact, clean, and fast implementation.
* - sizeof(TiXmlString) = pointer size (4 bytes on 32-bit systems)
* - fixed reserve() to work as per specification.
* - fixed buggy compares operator==(), operator<(), and operator>()
* - fixed operator+=() to take a const ref argument, following spec.
* - added "copy" constructor with length, and most compare operators.
* - added swap(), clear(), size(), capacity(), operator+().

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
}
