SXML example showing diff between node-reduce and node-join

[Matt Wette]

Hi All,

I'm going through the (sxml xpath) low-level routines to try to get a
solid understanding of what they do.  I just can't come up with an example
to show how node-reduce and node-join differ.   If someone could provide
such an example I would really appreciate it.  Takers?

My end goal is to write up a cookbook type note to show peeps how to use it.

Thanks,
Matt
