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
The following code fragment loads "books.xml"
into xmlDoc using
loadXMLDoc() and gets the text node from the first <title>
element in "books.xml":
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName("title")[0].childNodes[0];
document.write(x.nodeValue);

The output of the code above will be:
Example 2
The following code fragment loads "books.xml"
into xmlDoc using
loadXMLDoc() and gets the number of child nodes from the first
<book> element in "books.xml":
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName("book")[0].childNodes;
document.write(x.length);

In Internet Explorer the output of the code above will be:
In Mozilla browsers the output of the code above will be:
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.
