Hi All,
I am newbie to XML-XSL based programming. Currently I am facing issue with displaying XML node in sorted order along with grouping on nodes.

In the attached XML there is node for "Products" and under this node there are certain nodes which is unordered. I need to order these child nodes of "Products" and display the First letter for each group. The group here I mean is if 2 child nodes have "A" as starting letter then XSL should display its "label" node value and Group "B" for starting letter "B". For e.g. -
Product Category
A
Analyzer
Applied Discovery

B
Background Screening
Backup Disaster Recovery

D
Direct

and so on...

Can you all techies help achieving this for me. It would be great help
