This is probably because the xml file doesn't include an 

<?xml-stylesheet type="text/xsl" href="log.xsl" ?>

processing instruction in it.  Add that to the top of the xml (after the xml
declaration) and it might just work.

I'm glad there was some useful info in the talk. :-)

The XSL document you've got looks like it's pretty old (as xsl documents go)
and AFAIK script/eval is not supported by libxslt although similar is
provided with exlt extensions (http://www.exslt.org/).

I was able to get the xsl to compile with the attached file, but note that
the script and eval bits are commented out and have been re-written with
actual xsl.  Whether this works with your log file is another story. ;-)
