This pyparsing-based HTML stripper (http://pyparsing.wikispaces.com/
space/showimage/htmlStripper.py) strips *all* HTML tags, scripts, and
comments.  To pare down to just stripping scripts, just change this
line:

firstPass = (htmlComment | scriptBody | commonHTMLEntity |
             anyTag | anyClose ).transformString(targetHTML)

to:

firstPass = scriptBody.transformString(targetHTML)
