-/**

-	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.

+/**
+	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.
