It almost worked, but it put me on the right track.
What you gave me is not working as in your select, in the key function
second argument, the @aRef is not known in this context (this is not an
attribute of the A element. But I was able to achieve what I wanted doing
the following:
<xsl:key name="Crefs" match="C" use="substring-after(@aRef,':')"/>
select="A[count(key('Crefs',@name))>0]/B"
The condition in the select of the A element means any A referenced by at
least one C element.
Thanks a lot for the help.
Thomas

Subject: RE: [xsl] XSLT/XPath help to resolve definition references in a W
SDL XML fi le
hi Thomas,
I need some help on pure XSLT/XPath syntax/capabilities. Let's say
that I have an XML document looking like that:
<root>
<A name="a1"><B .../></A>
<A name="a2"><B .../></A>
<A name="a3"><B .../></A>
<C aRef="ns1:a1"/>
<C aRef="ns2:a2"/>
</root>
I want to be able to select all the B element which are under
the A elements
referenced by the C element (the A elements for which a
C/@aRef attribute
value, minus the prefix, is equal to the A/@name attribute).
Use a key on the C's:
<xsl:key name="CRefs" match="C" use="@aRef"/>
Then this as your path in <root> context.
select="A[(_at_)name = key('CRefs',substring-after(@aRef,':'))]/B"
Don't know if it works...
Tom
