Not to be argumentative but mearly trying to understand. Besides, whatever 
works, right?

There is some sample code under the XPathNavigator that shows recursive 
calls to XPathNavigator using MoveNext() starting out with 
MoveToFirstChild(). This would suggest that XPathNavigator handles more than 
one node. If not then what is the difference between XPathNavigator and just 
XmlNode?

Thanks again.
