(A follow up of this thread)
I now actually need to know the amount of visiters grouped by Day and then by period. I tried to apply the group-by suggested by Kirill Polishchuk, but I can only get it to group by one certain element. Now I actually need to know how to apply multiple group-by's? E.g. Group by 'Day' first and then by period.
I have the following XML:
<Cinema>
<Day date="15-09-2011" day="Thursday" week="37" in="543" out="543">
<Movie name="movie1" in="191" out="191">

<Period time="18:00:00" in="71" out="70"/>
<Period time="20:00:00" in="100" out="101"/>
</Movie>

What I am trying to get is the total visitors of each movie period per day. For example:
Thursday:
16:00h - in: 90, out: 90
18:00h - in: 180, out: 176
20:00h - in: 273, out: 277
Total - in: 543, out: 543
Friday:
16:00h - in: 299, out: 299
18:00h - in: 397, out: 395
20:00h - in: 455, out: 457
Total - in: 1151, out: 1151
Does anyone have any suggestions? Thanks in advance!
(I use xslt 1.0 at the moment, but it is possible for me to "upgrade" to the newer 2.0, if necessary)
