Can someone recommend a good perl module for XSL transformations other
than LibXSLT.  I need one that is pure perl so that it is
platform-independent.

Xalan from Apache is platform-independent. I use it on NetBSD
in its Java incarnation. There is also a C version. I input XML
and output XHTML that way. Then I use a Perl script to re-escape
the Unicode for old browsers.

...which is itself an example of just such output. It is not pure Perl,
but it works. Xalan is the ONLY Java which I do. I use Perl for most
other things.
