Looks
like Steve Saxon over at Dell is a XML person too. He’s got a great
article on MSDN, “XPath Querying Over Objects with ObjectXPathNavigator”.

So
my wish for an Object Query Language using XPath has been answered. He’s
handled issues with serializing the whole object graph, which makes it more
performant. For details heck it out the link, it’s a great read.
