Can grouping be done using XSL? Specifically, I have data which is
pulled by month, state. I need to add up the total for each month,
and the total for each state, in XSL style sheet.
For example,
Jan Maine 5
Jan Vermont 8
Feb New York 12
Mar Ohio 3
Mar Nevada 4
Mar Texas 8
Mar Maine 6
The results should be Jan - 13, Feb - 12, Mar - 15 and Maine - 11,
Vermont - 8, etc
How do I use style sheets to accomplish this grouping?
