Re: [xsl] Use XSL:Variable

Just to clarify, I *did not say* that variables are most used in
matematic calculations, far from that. I was saying they are variables
as they are used in the matematical equations, instead of they are
used in languages like Java ou Vb .

Glad you solved you're problem, remember that normally the ways to do
things ib XSLT are more simple then they appear at first, you just
have to think about then in a "xslt" way...

Fica bem.
