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?
you go up to the parent of sections which to far up, try:
section = xml.attribute(r, "..", "label", "X")
or
section = xml.filter(r, "../attribute(label)")
THanks and all best
Thomas
