I was told from a lecturer that web services could be used in place of XSLT to create a web application. I have no idea how this could be done and I am trying to find out how and why it could be done. Would this be a case of links on the page which when clicked would call a function in the web service which would return a page with specific content and layout? I would appreciate any information on this as I cannot seem to find anything related to this online.

Thank you!
