Re: [xsl] Manipulating elements depending on the existence of sub-elements

["Adil Ladhani" <dillio@xxxxxxxxx>]

Nice! The "following-sibling" function was exactly what I was looking
for, thank you very much Michael. My poorly parsed data now has it's
rightfully owned unique id information.

My only remaining issue is that the position() count is inaccurate for
the problematic "Item" (as it is contained in 2 "Item" elements rather
than one, so the count will be 1, 2, 3, 1, 2, 3 instead of 1, 2, 3, 4,
5, 6) but I'm guessing there isn't much I can do about this in XSL?
(since position()'s value *is* technically accurate, and I'm actually
trying to manipulate it)

If nothing can be done about it in XSL I can probably add a count in
.net prior to bulk loading.
