New subject: \xmlmap errors when returning key-value

16 Feb 2023

      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?

Background: I need to define column alignment based on the value of the <col> element inside the colgroup, so I was thinking about something like this :

\xmlmapvalue{colstyle}{dir: rtl}{align=righttolef }
\xmlmapvalue{colstyle}{dir: ltr}{align=lefttoright}

\startxmlsetups xml:table:colgroup:col
  \setupTABLE[c][\xmlpos{#1}][\xmlvalue{colstyle}{\xmlatt{#1}{style}}{}]
\stopxmlsetups

Best,
Denis
