Double-spacing makes your message much harder to read. I can only
comment in a general way, in any case. most html is mal-formed, and not
legal html. Although I don't have any experience with parsing it, I do
with xml which has similar problems.
The first thing I'd do is to separate the loading of the byte string
from the website, from the parsing of those bytes. Further, I'd make a
local copy of those bytes, so you can do testing repeatably. For
example, you could run wget utility to copy the bytes locally and create
a file.
