- If you call the Accept() method, it requires being passed a XMLVisitor
- class to handle callbacks. For nodes that contain other nodes (Document, Element)
- you will get called with a VisitEnter/VisitExit pair. Nodes that are always leafs
- are simply called with Visit().
-
- If you return 'true' from a Visit method, recursive parsing will continue. If you return
- false, <b>no children of this node or its sibilings</b> will be visited.
-
- All flavors of Visit methods have a default implementation that returns 'true' (continue
- visiting). You need to only override methods that are interesting to you.
-
- Generally Accept() is called on the TiXmlDocument, although all nodes support visiting.
-
- You should never change the document from a callback.

-/**
- 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
- 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.FirstChild( "Document" ).FirstChild( "Element" ).FirstChild().NextSibling().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
- XMLHandle handleCopy = handle;
- @endverbatim
-
- See also XMLConstHandle, which is the same as XMLHandle, but operates on const objects.

- an XML document.

+ * This class is a clone of TinyXML's TiXmlHandle class.
+ *
+ *
+ * A SP_XmlHandle is a class that wraps a node pointer with null checks; this is
+ * an incredibly useful thing. Note that SP_XmlHandle is not part of the SPXml
+ * 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, a
+ SP_XmlHandle checks for null pointers so it is perfectly safe and correct to use:
+
+ @verbatim
+ SP_XmlHandle rootHandle( parser.getDocument()->getRootElement() );
+ SP_XmlElementNode * child2 = rootHandle.getChild( "Element" )
+ .getChild( "Child", 1 ).toElement();
+
+ if( child2 ) {
+ // do something
+ }
+ @endverbatim
+ *
