Okay. I try to be more precisely. Please excuse my "bad" English :-)

The problem is that I have to program a solution for the following case.
My output should be a brochure with XML contents transformed via XSLT
to XSL-FO/PDF.

I have several "blocks" all with more or less the same structure. They
are named <section>. After <section> there are several items. My
resulting page has a print space of 180mm.

Now the problem:
I have to calculate the height of each <section> in mm (what I have
already done, stored in "&gesamt"). Afterwards I need to sum the
height of all the <section> items including their children. Now if the
height of the summation is <= 180mm I need a page-break and start the
same scenario at the following page. Sum the height, look if <= 180mm,
output, page-break. Of course I think I have to update the variable
"$gesamt".

Okay, I hope this helps more :-)

Thanks,
Andreas
