For some context, this is a very old stackoverflow answer. At the time there was a bit of a meme on SO that any question about regex and HTML would be answered with "you can't parse HTML with regex" which of course is true, but was probably applied a bit overzealously as while you can't parse the full HTML language with a reg ex, you can extract data in limited scenarios or subsets. This post was the culmination of that meme.
