Re: [xsl] Question about predicate

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

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
