XSLTO: Mapping XSLT to Objects
Here. When Tim Ewald was still a Microsoft employee, he and the next-gen MSDN content management system team experimented with some fun techniques for XSLT to Object mapping. To illustrate this technique, Kim Wolk has built a little prototype that lets you associate an XPATH statement with a method on an object and that method will be invoked for the nodes that match the XPATH statement. Check it out.
Update: Steve Dunn has ported Kim's sample from .NET 2.0 beta to .NET 1.1. Thanks, Steve!

Great code, but still I think the most common useage will need to work with the return value of ApplyTemplates and not to print it... how do i get the value of Age into Age procedure and not into the text procedure.
Thanks.
Thanks.

I've ported this concept over to Java-land: http://www.asciiarmor.com/blog/default/2005/03/02/Introducing_DAX.txt

Tim:
Avi,
When the Age method is invoked, the XPathNavigator is sitting ont the Age element. If you don't call the ApplyTemplates method, the XSLT transformation process will not continue. You can simply use the navigator to drill down and get the text value yourself.
Or, if you make the argument to the Age method an XmlSerializable class like this:
[XmlRoot("Age", Namespace="...")] // put namespace URI here
public class Age
{
[XmlText]
public string Value;
}
the engine will deserialize to that type and give you an object representing the current subtree. You can then simply access the value.
