Re: [xsl] fixing XSL search using values from a variable against multiple XML files

["Dave Lang emaildavelang@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Thanks for your reply, Syd.

re: doing this in another tool, I completely agree, but I have to use 
xsl for this particular task at this particular time.

fwiw, I find xsl to be very difficult to learn in this case because it 
is, at least as far as I can see, a pretty non standard usage for it. 
There are very few resources available online with working examples to 
learn from. The reddit xslt group has 50 subscribers. The two textbooks 
I looked at didn't include very helpful working examples either.

The original solution that started me down this path was (generously) 
presented to me on stackoverflow by Michael Kay. I'm sure some of you 
will recognize that name. This was great, but he acknowledged after that 
it was incomplete.

Anyway, thanks again for your help.
