XML/XSL unixish transform?

We've got this flow of dynamically generated XML data which I would like
to be able to use XSL to transform into either HTML or straight text
formatting for use in a CGI environment and an older character based
enviornment as well as for hardcopy generation.  Most of the XML
converters I've seen that are web-based expect staticish documents or want
to generate the complete output.  For mostly selfish reasons, I'd like to
be able to control the final output a bit, thusly:

dynamic XML generator -> XML-through-XSL transform -> my process

Given the volume of stuff we need to push through here, we need to zip
content through fairly quickly.  I don't need a very robust set of XSL/T
tags yet, just enough to run fairly simple transforms.

It sounds like what I need is a fast command line XML/XSL transformer for
UNIX (which also sounds non-java for the "fast" part).  Am I correct, and
if so, anybody know of a good one?
