getting XML file to show on separate pages using XSLT?

[Veikoh]

I'm not aware how much XML/XSLT programmers are in WebProWorld but anyway as member of the community will post my problem here with the hope that maybe somebody have experiences on those technologies.
My problem is, that I'm writing at the moment a simple mobile blogging platform for The Spoon community and decided to use XML technology as those are easy to integrate as RSS and as Search Engine sitemap. So each post is currently separate XML file, where is the possibility to add and read comments.
However, mobile screens are very small so I have a need to separate post comment functionality and each comment to separate page.
So first I tried to use XPointer ID's in XML file:
<ARTICLE ID="article">
....
</ARTICLE>
<COMMENTS ID="comments">
<COMMENT ID="comment1">
</COMMENT>
<COMMENT ID="comment2">
.....
But, accsessing those like http://www.xxx.com/file1.xml#comment1 didn't work for me. All the elements are still showing same time.
After few days work studding and trying different creative methods to pass URL parameters to my XSL module found out, that it's impossible. Using variables does not help as I still need to refresh the browser.
Does anyone have any ideas how to solve the problem?
Splitting everything as separate XML files would not be much viable option as I still need those for RSS and Site Map updates.
