Yes, I said in my original comment that it can't universally parse and validate every HTML document. If they're older pages that don't do lots of crazy formatting then it's not too hard to use regex as a first pass then take a second pass through the results to weed out the odd stuff.
I would argue that that is not parsing. That’s just pattern matching. For something to be parsing a document, it would have to have some “understanding” of the structure of the document. Since regex is not powerful enough to correctly “understand” the document, it’s not parsing.
