Several XSLT using one XSL sheet

Hello,

This is my problem:

This XML file contains all the downloadable documents of a user grouped by
section. Each downloadable document only belongs to one section. A section
can have many documents.

This my question:
I wonder how I could generate an HTML page for each section listing the
documents that belonging to it with only one XSL transformation, i.e.,
using only one XSL style sheet. Is this possible?

Any hint would be highly appreciated.

Thanks in advance
