I'm making a sitemap xsl file.
http://blahertech.dnsalias.net/_dev/sitemap.php
when I load it in a browser, I get "Error loading stylesheet: Parsing an XPath expression failed". I'm guessing most likely it's a error in the xsl file and not the xml file. This is a little harder to find since if I go to the xsl file, it won't show a error. So I don't really know what the bug is.

I don't know much about Xpath either, so I'm not sure what even the parsing error means.

If you want to quickly go to the xsl file it's at:
http://blahertech.dnsalias.net/_dev/templates/xsl.php
(firefox will ask to save it though since it's mime type is application/xsl+xml)

Any help, and I would be grateful.
