How to display multiple xml on a webpage?

[wahiggin]

I have an intranet website that I am working on and I would like to create a calendar along the top where the user can click on a date and the cooresponding xml file appears below. I call this a dynamic webpage, not sure if that is correct terminology or not. But I want a webpage that doesn't just have all of the xml files displays, only the one that the user request by date. Does anyone have something similar or know the code that I could use in Frontpage to make this work?

Thanks,
Wesley
