Re: [xsl] How to navigate in an expression (sort of)

[David Carlisle <davidc at nag dot co dot uk>]

Oh sorry for previous reply this is a key question.

(Which probably means I should leave it to Jeni to answer, but
anyway...)

given an id string you eant to get to element nodes that have
that string as the value of 
Foundation.Core.AssociationEnd.type/Foundation.Core.Classifier/@xmi.idref

Incidentally the above only looks horrible as you've gone in for this
computer science notion of understandable names, if you'd have caled it
x/y/@z
then it would have looked a lot more compact:-)

Anyway back to keys...

You want something like

<xsl:key name="x"
  match="Foundation.Core.AssociationEnd"
  use="Foundation.Core.AssociationEnd.type/Foundation.Core.Classifier/@xmi.idref"
/>

now in your template for Foundation.Core.Class you can go
<xsl:apply-templates select="key(@xmi.id)"/>

and you will apply templates to all (one) Foundation.Core.AssociationEnd
elements that have the stated property of having a key value of S.1.
(I hope)
