Hi everybody, I am trying to transform the XML file
"risultati_prova.xml" using the XSL file
"risultati_prova.xsl". Everything is working, except a WHEN condition
in the .xsl file (lines 119-126). In those lines I'm trying to use a variable called
"pusuff" (defined at line 22). I can't figure out why it doesn't work.
Can you please help me? Thanks, Alex Below you can find my two files: the first one is
XML, the second one XSLT.

Looks like a scope problem. Make your variable a global at the top of the
stylesheet, and remove the quotes around '$pusuff' when you use it.

A good place to get XSLT coding help is the xsl-list at mulberrytech.com. This forum
is intended for problems specific to the Saxon product - it's not a free stylesheet
debugging service. The most obvious thing wrong with this like of code: <xsl:when
test="./voto_scritto/@punti<'$pusuff'"> is that the
variable reference $pusuff is in quotes. The next thing wrong with it is that the
variable isn't in scope (it's only in scope within the <table>
element).

Thanks a lot for all your replies and support. And sorry for posting such a trivial
question on this forum. I've just started using XSLT and I was desperate for an
answer... All the best, Alessandro
