[xsl] Dynamic javascript array loading in XSL page.


Subject: [xsl] Dynamic javascript array loading in XSL page.

All:
First of all, I am an absolute newbie for XSL but I am trying....

I have been tasked with taking over a collection of XSL pages which produce
HTML forms.
Some of the pages contains script in CDATA blocks and I need to enhance the
functionality for some of them.
In particular, I need to build small matrices do be displayed in child
browser windows.
Given that I do not want to use hidden tags, I elected to load a javascript
two-dimensional array.
So...., given a XML source file similar to the one below, how can I laod the
data in the html page? (so I get the 'desired result' below)

I have included my first (and second) attempts to do this just for laughs
but of course, nothing works. I would really appreciate it if anybody gave
me any pointers. In the meantime, I'll just go back to reading Michael's
book (excellent but not easy to follow) between training bouts at Zvon.org.
(thanks for the pointer Joerg)

TIA

Patrice
