Ok if  the requirement is to group all the products of the same id together,
I would follow the following steps.
1. Get all the unique nodes
2. Group all the products with the id as defined by the id of the unique
node.


Is there any other way we could avoid using two nested  loops for a
requirement like this?
Thanks
