Hi all,
one of my favorite topics… Here is a minimal example which shows something that
I don't understand: when I process the subsection with the lua code, I want to
get the value of the current section's "label" attribute in xml.attribute(r,
"../../section", "label", "X"). So i was expecting that lua would go up
(../../) and fetch the current section's label. But if you run the example, you
see that it actually always gets the first section's label (value is always 1).
How can I get the current section's label with a lua function?
THanks and all best
Thomas
