Hi,
I’m getting unexpected results for \xmlpos
With the example below, I was expecting to get the following positions:
1 2 3 4
However the result is: 2 4 6 8, i.e. each time it’s exactly the double.
What am I missing?
that there are spaces between elements .. you can try:
\xmlmatch {#1}
instead

Thanks, that does the trick.

However, now I get an error when I try to return a key-value setting via xmlmap, see below. Any hints why this does not work

\xmlmapvalue{colgroupalign}{dir: rtl}{align=righttoleft}
\xmlmapvalue{colgroupalign}{dir: ltr}{align=lefttoright}

as opposed to:

\xmlmapvalue{colgroupalignvar}{dir: rtl}{righttoleft}
\xmlmapvalue{colgroupalignvar}{dir: ltr}{lefttoright}

?

Best,
Denis
