Re: Question about predicate

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[(_at_)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[(_at_)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
