If using XML, you need to access the data using DOM functions.
As for not loading jQuery -- that's fine. But your current AJAX component is insufficient.
I would start here [w3schools.com], going through the next several pages. That way your own AJAX component can be put into its own file for easy reference in multiple projects.
