Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Well there is no easy way to do that other than comparing each element in the two XMLs and creating a new one with the desired value. You will have to traverse the two documents and do this. You can use XPath to make this easy for you.
