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

["Lizzi, Vincent vincent.lizzi@xxxxxxxxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi Dave,

The solution from Michael Kay is definitely on the right path. Which part of
your requirements is it not doing?

Could you describe the environment where the XSLT will be used? Does it need
to run in oXygen, which you mentioned, or inside another system? Are you using
Saxon-HE, Saxon-EE, or another XSLT processor?

It would be very easy to provide a solution using BaseX<http://basex.org/>,
which is another part of the XML ecosystem. Would it be worth exploring this
option?

I have found that many of the learning resources available for XSLT are not
great for beginners, but once you get familiar with a few of the tools
learning accelerates and XSLT can become part of your go-to toolkit. I can
recommend a current-favorite book, bBeginning XML, 5th
edition<http://www.wrox.com/WileyCDA/WroxTitle/Beginning-XML-5th-Edition.prod
uctCd-1118162137.html>b by Joe Fawcett, et al, published by Wrox. The XML
Summer School<https://xmlsummerschool.com/> offers a great hands-on course if
the time and location work for you, and there are other hands-on trainings
available from other sources.

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.

dave
