You're getting that problem because you're concatenating lots of text
togther rather than building the node set :)

What you want to do is find the Pagina with @Tipo = 'New', then find
within that the 'texto' element that has an @ID equal to 'Equita12'.
In fact, the string that you constructed is almost the XPath that you


Note the '/' at the beginning - that says "go back to the root node
and navigate from there".  Without that '/', you'd be looking for
'Paginas' children of the *current node*, which isn't what you want.
So to set the variable 'W' to this node set (all the textto elements
with @ID equal to 'Etiqueta12'), use:

  <xsl:variable name="W"
                select="/Paginas/Pagina[@Tipo='New']/texto[@ID='Etiqueta12']" />

I hope that helps you get over this hurdle,
