I essentially need a countif() function for xsl. Something to where I could
do countif(node-set, condition). Rather than try to get too extreme, i
decided to just write one for my countif() with the condition hardcoded.
(this was also my first venture into creating "functions" )
Pseudo-code is essentially this: Look at the current node and check the
condition. If the condition is true, call our function again with an
incremented count. If false, call function with the same value. Once we
reach the end of the node set, return the counter variable. The whole time
we're passing around a node-set and a current index.
My problem is that i get an error when i try to index into the node-set like
this $node-set[$index]. It looks like when i call the template and pass in
a node-set using the select attribute, it converts that node-set into a
string? (according to some posts i've read) So ways around that were to
use the mxsl:node-set(). The problem is i tried that and it didn't work.
(I'm using .NET to do the transform)
The other question I had was if i can even index into a node set like i'm
doing? Or maybe there's a better alternative for what i'm trying to do?
Thanks,
