Welcome to the club. It's because of things like that that I added my
second paragraph:

"You'll probably discover that you want to add refinements (perhaps to
deal with HTML encodings like &nbsp; and &lt; - but those can wait on
getting the initial version working."

The refinements will depend on whether the OP wants a general solution
or just enough to extract data from one particular page. On
re-reading, I'd guess is that <table>, <tr>, and <td> tags may be his
1st refinement - but the question indicated that he'll probably need
to start at the most basic level.
