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)"/>

Enjoy,
Wendell

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
