HTML, XML, XSL and Javascript

OK. Here is what I am trying to do…

I have several HTML pages that I would like to bring in a bit of information using XML/XSL. I can get this done using javascript. No problem yet. The thing that I would like to do is bring in a filtered list based upon the current HTML page. I haven’t been able to find any good information on how to go about doing this. The only thing that I could think of is to make an XSL doc for each page, but that seems very redundant.

basically, I would like to have a filtered list of HTML show up on different HTML pages that is generated by a single XML doc filtered by a single XSL doc.

I don’t mind clarifying if this is unclear.
