XML DOM childNodes Property
 Complete Element Object Reference
Definition and Usage
The childNodes property returns a NodeList containing the child nodes of
the selected node
If the selected node has no children, this property returns a NodeList
containing no nodes.
Syntax
Tips and Notes
Tip: To loop through a childNodes list, it is more efficient to use the
nextSibling property than to explicitly use the childNodes list of the parent
object.
Example 1

Example
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName("title")[0].childNodes[0];
document.write(x.nodeValue);

x=xmlDoc.getElementsByTagName("book")[0].childNodes;
document.write(x.length);

Firefox, and most other browsers, will treat empty white-spaces or new lines
as text nodes, Internet Explorer will not. So, in the example
above, the output will be different.
