mangled attempt at using htmllib

Wow! I got sick for a few days and missed this very, very useful
tutorial. As it happens, my goals were slightly different that was
apparent from the code:

>> 200 OK        <a href="urlstatusgo.html?col=test&url= /
http%3A//www.foobar.com/archive/091400.html"> /
http://www.foobar.com/archive/091400.html</a>
>
>Well, I think your first misapprehension is that you appear to be
expecting HTTP back >form the urllib readlines() call, when in fact the
HTTP is stripped off, and what *you* >see is just the HTML!

I knew that this particular page would yield such lines. The idea was
to evaluate each such line and grap the URL between the anchor_bgn and
anchor_end, in the example shown, a simple

http://www.foobar.com/archive/091400.html

This might have been done more simply with regular expression, e.g.,

   myUrl = re.search(r'<a href.*?>(.*?)</a>)

because, as I seem to be discovering, the "handle_data" stuff in my
parser class

>>    def handle_data(self, data):
>>            self.c_data=self.c_data+data

doesn't refer to the data inside the anchor tag, which is what I
wanted, but to something else (or, my current modules aren't asking for
the right thing the right way, because printing the contents of
self.c_data gives me "none" as a result.

Anyway, just getting straight on idiosyncracies of htmllib and being
reminded that cutting and pasting python code almost ALWAYS requires
attention paid to spaces--tabs convert oddly, and the interpreter on my
machine sees them as different, regardless of what they look like, has
moved me forward in very nice, useful ways.

Thank you!
