I removed all the nodes without <date>. Still the grouping isn't working.
Updated xml/xsl below:
thanks,

I haven't looked through this in detail, but if X has no date child,
then X[date=$date] will always select nothing (any "=" comparison with
an empty node-set returns false). If you want two non-existent dates to
compare equal, force the value to a string: X[string(date)=$date] - do
this wherever you use the date as a grouping key.
