Thanks for the tips.

I still can't quite get it to work. Perhaps I'd better explain in more
detail. I'm actually working with XQuery (though the problem is more an
XPath more than an XQuery one). My XQuery statements select all the
'hierachical nodes' (i.e. the sections and subsections) and, for each
one, I want to extract all the text of its child nodes (those /without/
and 'id' attribute) but not the text of its child /hierarchical/ nodes
(those /with/ an 'id' attribute).

for $section in collection("...")//section

seems to cause the script to crash :-o


for $section in collection("...")//section

will select all the text of the $section, but also of its child
'subsection' etc. elements (which I don't want).

I'll carry on fiddling.
