	In this example, we navigate a simple XML

	checking; working code should check for null
	pointers when walking an XML tree, or use
	XMLHandle.
	
	(The XML is an excerpt from "dream.xml"). 

	@skip example_3()
	@until </PLAY>";

	The structure of the XML file is:

	<ul>
		<li>(declaration)</li>
		<li>(dtd stuff)</li>
		<li>Element "PLAY"</li>
		<ul>
			<li>Element "TITLE"</li>
			<ul>
			    <li>Text "A Midsummer Night's Dream"</li>
			</ul>
		</ul>
	</ul>

	For this example, we want to print out the 
	title of the play. The text of the title (what
	we want) is child of the "TITLE" element which
	is a child of the "PLAY" element.

	We want to skip the declaration and dtd, so the
	method FirstChildElement() is a good choice. The
	FirstChildElement() of the Document is the "PLAY"
	Element, the FirstChildElement() of the "PLAY" Element
	is the "TITLE" Element.

	@until ( "TITLE" );

	We can then use the convenience function GetText()
	to get the title of the play.

	@until title );

	Text is just another Node in the XML DOM. And in
	fact you should be a little cautious with it, as
	text nodes can contain elements. 
	
	@verbatim
	Consider: A Midsummer Night's <b>Dream</b>
	@endverbatim

	It is more correct to actually query the Text Node
	if in doubt:

	@until title );

	Noting that here we use FirstChild() since we are
	looking for XMLText, not an element, and ToText()
	is a cast from a Node to a XMLText.

	There are fundamentally 2 ways of writing a key-value
	pair into an XML file. (Something that's always annoyed
	me about XML.) Either by using attributes, or by writing
	the key name into an element and the value into
	the text node wrapped by the element. Both approaches
	are illustrated in this example, which shows two ways
	to encode the value "2" into the key "v":

	@skip example_4()
	@until "</information>";

	TinyXML-2 has accessors for both approaches. 

	When using an attribute, you navigate to the XMLElement
	with that attribute and use the QueryIntAttribute()
	group of methods. (Also QueryFloatAttribute(), etc.)

	@skip XMLElement* attributeApproachElement
	@until &v0 );

	When using the text approach, you need to navigate
	down one more step to the XMLElement that contains
	the text. Note the extra FirstChildElement( "v" )
	in the code below. The value of the text can then
	be safely queried with the QueryIntText() group
	of methods. (Also QueryFloatText(), etc.)
