There are no stupid question... I'm not in a position to say that
questions are stupid ;)

... Stupid question, but are you transforming it on the server side
first, or are you just putting an <?xml-stylesheet?> reference in your
XML and expecting IE to transform it?

Subject: RE: [xsl] Sorting Two Dimensional Table
Hi,
Thanks for that answer but unfortunately, I can't get it to work. I
don't know if it is due to the fact that I'm using Internet Explorer to
see the transform but I'm getting this error:
'Reference to variable or parameter 'k1' must evaluate to a node list.'
I tried to debug it but I'm not too convinced of what I'm doing is good.
In the article http://www.dpawson.co.uk/xsl/sect2/N8090.html, question 4
(you wrote it), I'm suppose to get only one node but I think what we
want is a sorted nodelist of the keys. I'm not sure what the xs:string+
is but it seems to be a string. Is it possible that I should be using
something like what is described by Andrew Welch in
http://ajwelch.blogspot.com/2007/02/csv-to-xml-converter-in-xslt-20.html
to get a nodelist from the values that are concatenated (this is a guess
based on my understanding of question 6 by Jeni Tennison of
http://www.dpawson.co.uk/xsl/sect2/N8090.html )
If you can help me again to debug that one, it would be appreciated.
Thanks again.
Pierre
