I need to design a web site in which data is passed to and from the server using XML. I got it how to transform data from database to XML and then to HTML, but I am not able to find how to pass data from client to server using XML. My webpages are designed using ASP. Is it possib开发者_高级运维le to do pass data from client to server using XML. What are the things that are to be studied?

AJAX might be the way to go.
