[xsl] RE: RE: building a nodeset from selected nodes

["Hall, Kurt" <khall@xxxxxxxxxxx>]

Hmmm.  I have the Kay book, and I've written over 3000 lines of
xsl, so those aren't the only requirements :-), but I confess to
not using the key() function before.  My misreading of the original
response and the Kay book was that the second parameter to the
key() function was a single value, not a node-set as is now
obviously possible.

Thanks,
-kurt

Hi Kurt,

Wendel gave you the key to the exact solution to your problem.

You don't understand it at present and this means that you need to read a
good book
on XSLT -- I'd recommend Mike Kay's "XSLT Programmer's Reference".

Otherwise the only way to show to you that Wendel's solution is correct,
would be to
write the complete code of the stylesheet so that when you apply it to your
xml
source you'll have to agree with the fact that it produces exactly the
desired
output.

But of course, this would not be useful to you at all -- you need to be
gettting
some experience -- therefore read more and try to write XSLT code.

Cheers,
Dimitre Novatchev.
