Indeed this is related to a concrete programming problem. I'm trying to
write a small class to parse html tables into lists. Of course, I have
searched Parnassus for such code, but what was available didn't support
embedded tables. I'm therefore writing my own class to recursively go
through embedded tables and I think I'm almost there. If you like, I can
send you my code once finished, I'd be very interested in what insight you
could offer.

Thanks for the help
