-/**
-	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.

+
+	If you return 'true' from a Visit method, recursive parsing will continue. If you return

+	visiting). You need to only override methods that are interesting to you.

+	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-2
+	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.FirstChildElement( "Document" ).FirstChildElement( "Element" ).FirstChildElement().NextSiblingElement();
+	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.
