Big question - Will the group of codetype/code elements for a particular id
always be grouped together as in your example?  I imagine they will, if the
query sorts them by product id.  Then perhaps you can output a product
element only for the first occurrance of a particular id by its position
(that is, the first time a particular id appears in the order, you create a
product element).

Better would be to change the creation method of the xml so it is more
sensible.

Either forget the MS parser or use the current updated one, MSXML3, which
does have variables and most of the other nice things in the xslt Rec.  The
old one will slowly fade away.  Transform the xml at the sending end and not
the browser if necessary.
