You probably need to use the following-sibling:: axis (which looks at
the siblings of the node you're looking at - the week elements that
have the same parent entry in other words) instead of the following::
axis (which looks at *all* the following nodes in the document, no
matter where they occur [aside from descendants, of course]).

So try:

  week[not(@opp = following-sibling::week/@opp)]

or:

  week/@opp[not(. = ../following-sibling::week/@opp)]

Alternatively, you could use a key and the Muenchian grouping method
to create your groups. That will probably be more efficient,
especially if you have lots of week elements. Have a look at
http://www.jenitennison.com/xslt/grouping/muenchian.html for a
description.

I hope that helps,

Jeni
