Can you parse html with regular expressions?

RegEx is powerful, yes. But HTML (even though it's a standard) can be buggy, inaccurate, and difficult to expect. Some people, encouraged by older books that support the method, don't close things like `<p>` tags. Others omit the self-closing / on certain tags because they can (i.e. hr, br, img).

So can you use regular expressions to parse a known subset of expected HTML? Probably. Could use use it to parse arbitrary, unfiltered, potentially broken HTML? No. And you wouldn't expect to use RegEx to parse any other broken text document that fails to follow a defined, knowable schema either.
