Hi Jeff,

David Carlisle already showed you how to do it in XSLT 1.0 with mode switching. I don't know if you have the possibility to use XSLT 2.0, but here's a solution that does the same in XSLT 2.0, with the help of a little function that turns any range of attributes into a hierarchical node list, making it easier to use with matching templates. It's perhaps a bit non-conventional, but it keeps your code pretty tight.

Output from your source is equal to the requested output.

Happy coding!
