Lightweight XSLT based web framework

Hello,

I'm searching for a lightweight XSLT based web framework for simple
web pages. I hope someone from this list can help me.

I know (and like) cocoon very much, but I need a more simple and
smaller system. All I want to have is the possibility to transform XML
with XSLT, caching of the results and maybe a system that generates
the site-navigation.
An integrated CMS would be nice but is not very important.

Does anybody know such a system (PHP preferred but Java is ok too)?

Thank you,
Peter
