Didier,
You want the current() function, which returns the current node (typically the node that has matched the template) irrespective of what the context node happens to be (e.g. inside a predicate, where the context node has changed).
So:
<xsl:apply-templates select="//rdf:description[@about=current()/@xlink:href]" />
But you'd get better performance using a key:
<xsl:key name="descs-by-about" match="rdf:description" use="@about"/>
Then
<xsl:apply-templates select="key('descs-by-about',@xlink:href)"/>

Hi
I didn't wrote a stylesheet since quite a long time and I am completely rusted. Since this morning I am trying to match certain templates without success. I want to do: <xsl:apply-templates select="//rdf:description[@about="the unknown expression here."]" /> my problem is with the second part of the equation ("the unknown expression here"). I want it to match with any rdf:description element having its attribute "about" equal to the value of ./@xlink:href (the currently matched node having an xlink:href attribute). I tried different expressions without success. Any help on that will be greatly appreciated.
Many thanks Didier PH Martin
