/** @page Example-3 Get information out of XML
@dontinclude ./xmltest.cpp
In this example, we navigate a simple XML
file, and read some interesting text. Note
that this is examlpe doesn't use error
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.
