RE: FW: Sort on multiple key

Yes I read the book regarding Muenchian grouping but I couldn't get my
head round it for my case. Unfortunately I only use XSLT rarely.

Sorting changes the order in which you process the nodes but it doesn't
change their position in the tree. So any use of XPath axes will reflect
the
original order of the nodes.

If you're using XSLT 2.0 you can solve this very easily using
xsl:for-each-group group-adjacent="...". With 1.0 it's rather harder.
Use
Muenchian grouping to identify the groups, then process the groups in
sorted
order.
