[xsl] Can I group 3 levels somehow

["gary cor" <stuff4gary at hotmail dot com>]

Dear all,

My XML is...

I am trying to group xml elements using three attributes.

i.e.

- Firstly, I want to group them by the imagetype

----  Then within these imagetype groups, group by ordinal

---------- then within imagetype and ordinal I want to groupby imageparentid

Is this possible can anyone help.

Many thanks in advance

G.
