Werner:
We sorted it out--turned out to be much more elaborate than we thought, but
your suggestion of following-sibling was key. I was thinking in terms of
preceding, but that wasn't going to work. We had to get very elaborate to
account for commas and the use of "and" between names, but other than that
it was okay. Had to do a line counter to keep track of how many lines we
were allowed to use.
Here's the code we developed, in case you're interested. Thanks!
Sherrod
