folder tree representation using xsl and xml

I have an xml file and I want to make a folder tree representation of this
xml file, much like in this article.
http://www.15seconds.com/issue/010921.htm The reason this article does not
work for me is because it is IE dependant and i want to make my xsl browser
independant.

also, I would like to do my xsl transformation on the server side (using
servlets) and send the html back to the client browser with the tree
information which can be expanded and collapsed.

I would really appreciate it, if any of you would point me to some code
samples that you might have used yourself or found over the internet. i have
been looking for this for a while. (am not much of an xsl guru)

thanks.

TP.
