Hi
struggling again: Shouldn't the code below give me the last element
under <tbody>? Right now
\xmlfilter{#1}{/tr/last()/command(xml:table:tbody:tr)} gives me nothing...
(Use case is that I want to have a frame above the table and one bar
below. So I think I should wrap the last line in the \startxtablefoot
...\stopxtablefoot, i.e., I need one command for the last element, and
one for the rest (Or is there a better way?). What would be the
everything but the last?
What am I missing?
Thanks again,
Denis

You need to read some more on the "Expressions and filters” chapter of the xml manual, as it does not work quite the way you think. Here is a quick fix:

\xmlfilter{#1}{/tr[position()==last()]/command(xml:table:tbody:tr)}
Best wishes,
Taco

Thanks! That works. I have to admit, it's not entirely clear to me.
I adapted my pattern from the one given on page 78: /whocares/last()
Obviously, it's not that easy.
Best,
Denis
