How about something like: echo '<title/>' | xsltproc --param sf-relid "'CURRENT'" --noout --nonet --xinclude http://docbook.sourceforge.net/release/xsl-ns/current/VERSION - The --nonet switch ensures it will only use a local file, but the XML catalog is still used to translate the canonical URL to a local file, so doesn't depend on a a specific path for the local file
