Summary: allow HTMLParser error recovery
Initial Comment:
I'm using 2.3a2.
HTMLParser correctly raises a "malformed start tag"
error on:
<meta NAME=DESCRIPTION Content=Lands' End quality...
outerwear and more.>
because my application is imprecise by nature (web
scraping), I want to be able to continue after such errors.
I can override the error() method to not raise an
exception. To make this work, I also needed to alter
HTMLParser.py, near line 316, to read as:
self.updatepos(i, j)
self.error("malformed start tag")
return j # ADDED THIS LINE
raise AssertionError("we should not get here!")
My enhancement request is for every place where
self.error() is called, to ensure that the "override
error() to not raise an exception" continuation
strategy works as well as can be hoped.
Thanks,
Steve

Fixed by my patch against 2.3.3.
The patch adds recovery to ensure progress and tries to not
miss any data in the input.
The error() method is now commented as being overridable,
just def error(): pass to ignore any parsing errors.
