Hi Manfred,
Thank you for your help. I trully appreciate it.
I am trying to code the xslt stylesheet using your
suggestion (using templates to take care of the
hierarchy) but I have to confess that I am a bit lost.
I was wondering if you could have a look at the
stylesheet below and make the necessary changes.
Also, I have not tried your simpler approach yet
because I am trying to understand this one first.
As for the Javascript, I will create a test harness to
test all the stylesheets and let you know the one with
the best performance.
Cheers
