Thank you all!

I was a little apprehensive it could be a silly mistake. And so it was. 
I have BeautifulSoup somewhere. Having had no urgent need for it I 
remember shirking the learning curve.

lxml seems to be a package with these components (from help (lxml)):

PACKAGE CONTENTS
     ElementInclude
     _elementpath
     builder
     cssselect
     doctestcompare
     etree
     html (package)
     isoschematron (package)
     objectify
     pyclasslookup
     sax
     usedoctest

I would start with "from lxml import html" and see what comes out.

Break time now. Thanks again!
