That was a quick response, thanks, but

I do not sort them, they are sorted in my xml-file. 
When i change the amount of memory to 256 i have no problem,
but i can not keep enlarging the memory. 
The XML-file can vary in size from 100kb up to 10MB and higher.

I've tried the following-sibling axis, but then i get errors from
FOP. I think the way i'm doing it is wrong. Most examples i've seen
only use xsl, but not together with FOP. 
Do you have experience with Apache FOP and grouping ?

Do you sort the records? Also, if you're using FOP, are you sure the memory doesn't run out in the FO processing, instead in XSLT phase?

Select only

  record[position() mod 2 = 1]

and there process the current record and the following one using the following or following-sibling axis.
