This is really, really simple. You should be able to do this very easily if you're in a class or something. If not you need to visit http://www.w3schools.com/xsl/ and start doing the tutorial. This should take you maybe a couple hours tops if you have any development experience.
Once you actually ATTEMPT a solution, I'll be willing to help you fix it. Post your attempt (please use codeboxes, for your xml documents) and I'll happy to help.
