Michael is correct it can be done with a XSLT stylesheet if the schema 
instances are all in the same namespace.  I wrote such a stylesheet for 
work, but needed to use a SAXON extension to keep track of what had 
already been added to the output document.   Unfortunately, I currently 
can't share this stylesheet, unless work gives me permission.

If you search the XSLT mailing list, you should find some sample code 
that I had written that should point you in the  general direction.
