110 Implements the interface to the "Visitor pattern" (see the Accept() method.)
111 If you call the Accept() method, it requires being passed a TiXmlVisitor
112 class to handle callbacks. For nodes that contain other nodes (Document, Element)
113 you will get called with a VisitEnter/VisitExit pair. Nodes that are always leaves
114 are simply called with Visit().
115
116 If you return 'true' from a Visit method, recursive parsing will continue. If you return
117 false, <b>no children of this node or its sibilings</b> will be Visited.
118
119 All flavors of Visit methods have a default implementation that returns 'true' (continue
120 visiting). You need to only override methods that are interesting to you.
121
122 Generally Accept() is called on the TiXmlDocument, although all nodes suppert Visiting.
123
124 You should never change the document from a callback.

1551/**
1552 A TiXmlHandle is a class that wraps a node pointer with null checks; this is
1553 an incredibly useful thing. Note that TiXmlHandle is not part of the TinyXml
1554 DOM structure. It is a separate utility class.
1555
1556 Take an example:
1557 @verbatim
1558 <Document>
1559 <Element attributeA = "valueA">
1560 <Child attributeB = "value1" />
1561 <Child attributeB = "value2" />
1562 </Element>
1563 <Document>
1564 @endverbatim
1565
1566 Assuming you want the value of "attributeB" in the 2nd "Child" element, it's very
1567 easy to write a *lot* of code that looks like:
1568
1569 @verbatim
1570 TiXmlElement* root = document.FirstChildElement( "Document" );
1571 if ( root )
1572 {
1573 TiXmlElement* element = root->FirstChildElement( "Element" );
1574 if ( element )
1575 {
1576 TiXmlElement* child = element->FirstChildElement( "Child" );
1577 if ( child )
1578 {
1579 TiXmlElement* child2 = child->NextSiblingElement( "Child" );
1580 if ( child2 )
1581 {
1582 // Finally do something useful.
1583 @endverbatim
1584
1585 And that doesn't even cover "else" cases. TiXmlHandle addresses the verbosity
1586 of such code. A TiXmlHandle checks for null pointers so it is perfectly safe
1587 and correct to use:
1588
1589 @verbatim
1590 TiXmlHandle docHandle( &document );
1591 TiXmlElement* child2 = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).Child( "Child", 1 ).ToElement();
1592 if ( child2 )
1593 {
1594 // do something useful
1595 @endverbatim
1596
1597 Which is MUCH more concise and useful.
1598
1599 It is also safe to copy handles - internally they are nothing more than node pointers.
1600 @verbatim
1601 TiXmlHandle handleCopy = handle;
1602 @endverbatim
1603
1604 What they should not be used for is iteration:
1605
1606 @verbatim
1607 int i=0;
1608 while ( true )
1609 {
1610 TiXmlElement* child = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).Child( "Child", i ).ToElement();
1611 if ( !child )
1612 break;
1613 // do something
1614 ++i;
1615 }
1616 @endverbatim
1617
1618 It seems reasonable, but it is in fact two embedded while loops. The Child method is
1619 a linear walk to find the element, so this code would iterate much more than it needs
1620 to. Instead, prefer:
1621
1622 @verbatim
1623 TiXmlElement* child = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).FirstChild( "Child" ).ToElement();
1624
1625 for( child; child; child=child->NextSiblingElement() )
1626 {
1627 // do something
1628 }
1629 @endverbatim
