Hi Tambet,

thanks for your answer. Worked as expected!

The dynamic is because we don't know what's in the items, this changes
from call to call.

(And that's why we use
<xf:repeat nodeset="./*[node()]" id="table-item">
in the inner loop. This omits the empty tags. That wasn't clear in the
example.)

But:
Where can I find documentation on how to build such XPath. Or some
introduction to have more chances to get things like this running at my own

Thanks

Cheers

Heinrich
