There's a metadata-extractor step that does this:

<p:declare-step type="cx:metadata-extractor">
   <p:output port="result"/>
   <p:option name="href" cx:type="xsd:anyURI"/>
</p:declare-step>

Unfortunately, it's a little fiddly to setup because the underlying
library is transitioning from one API to another.

There's also a Saxon extension function you can run from XSLT that
will do it. It's part of the DocBook stylesheets.

                                        Be seeing you,
                                          norm
