Actually, I missed something in the original regex, above. (Funny how I
noticed just after I pressed the 'send' button!)

It should read like this:

_convert_regex =
re.compile('''<!--#(/?)(([^"-]+?|"[^"]*?"|'[^']*?'|-[^-])+?)-->''')


The whole thing again -- same disclaimers apply, only more so :-)
