Re:  Sorting in A for-each-group
Thanks David this works for me, but I'm at a loss on how this happened. In my input files i have nested div elements that i want to group, so i have 3 nested for-each-group instructions to handle the grouping. The 1st for-each-group will group the 1st level div element according to their @id. Then the second for-each-group for the 2nd level div and this div elements are the one i want to sort so i assumed that this is where i need to place the sort instruction. But in your solution you placed the sort instruction in the 3rd for-each-group and it produced the correct results, this is what i'm confused about, isn't this suppose to sort the current-group in the 3rd for-each-group which is the 3rd level div elements?

which meant the stylesheet as posted didn't select anything.

I suspect that your only problem is that 10 is sorting before 3 as it's
doing strings not numbers.
<xsl:sort data-type="number" select="@n"/>


I can't readthis xml by eye to really spot what is being sorted where but i get:
