Yes, this gets me over the hump just fine, thanks. I'm now able to write
out the result of SQL queries as XML and then, with only a few lines of
additional code (subclassing Walker), alternatively write it out in my
company's proprietary typesetting markup. And this after less than a
month's acquaintance with Python. I think I'm in love!

When I have a little more time, I'll also look at Gabe Wachob's Visitor
class (recently posted to this list), to see if I can also do it the way
it 'should' be done. :-)

Thanks for everything.
