Hello,
I'm having an issue while counting and aggregating nodes that have similar
subnodes value within the same category.
In other words I'm trying to do something like a group by (in sql)
I must be doing something wrong somewhere. Please see my xml, stylesheet
and output to see what I'am trying to accomplish.
Thank you all 4 ur help.
