Webchecker version 1.25.6.1 on Windows 2000 
Professional. 

Run webchecker with this argument 
http://www.naleo.org/WSJArticle002.htm 
Webchecker will return this traceback:

I believe this is because of the xml in the source code 
(see WSJArticle002_source.txt attached to this bug 
report).

Even if the code in this page is poorly formatted, 
webchecker should be able continue checking other 
links in this domain (rather than stopping). For example 
webchecker could report “unable to check 
http://www.naleo.org/WSJArticle002.htm” and return 
traceback like the above, and then continue with the rest 
of the domain.

I've seen a variety of parsing problems kill webchecker.  I
agree that these exceptions should be caught somewhere so
that they are not fatal.  Care to submit a patch?

I'd love to submit a patch, but I am a newbie to both Python 
and programming. I apologize if this space is only intended 
for programmers; I am a QA engineer just getting acquainted 
to the wonderful world of Python.

No need to apologize.  Everyone is welcome to submit bug
reports here.  There are, however, lots of programmers who
submit bugs, so I find it helpful to ask :-).  I'll look
into this, but it's not the highest priority.
