[xquery-talk] Query to return nested xml tags

[Michael Kay]

What you are doing seems to be completely weird, but you presumably have
your reasons. I can't see why you expect it to produce the opening tags in
one order and the closing tags in a different order. The result of
ancestor-or-self::* is in document order, that is, outermost element first,
and that's what you are seeing.
