The problem is: you cannot parse malformed (real, everyday) html with regexes. But if you need to parse html even malformed) generated by the same template (like a scrapping situation), the whole file becomes regular, which can be parsed by a regular expression. But if you try to parse html in general, too bad because then you’ll need to take html in consideration and will need a recursive descent parser, not a regex. This question popped up so many times in forums in 2000’s that people got mad at that.
