Re: Parsing HTML Using Regular Expressions
#2you know when you first read that you think - damn straight you can't parse html with regex, but as it goes on the idea gets strangely enticing. I mean maybe, with the correct rituals, and a gun and a willingness to fight with ancient evils you could maybe parse some html with regex. A sort of Lovecraft/Action flick.

beautiful soup is a better tool.
Regex is fine for grabbing something in a page that you have looked at yourself.

It’s an acceptable choice for scraping, because with scraping you usually go into it with the expectation that it will break and need updates sometimes as the scraped site changes. The warning bells are more for things like validating user input on your own site, where there might be security implications of an impossible parsing task.

And I use a handgun to hunt houseflies in my motel room after a week long crystal meth binge. Works just fine for me.
