In ajax you can use jQuery, very simple to use if you don't want to use script manager.

You need to be more specific. Are you creating a control that has client functionality or you just need to expose the XML on the client? In the first case you can pass it through a script descriptor, in the second, you can use a web service and call it from javascript. Please provide more details.
