I read a post a few days ago about someone saying something like "shame on you for using regex like that". I just finally understand what regex is and that statement doesn't make much sense to me. Regex is like patterns and substitutions, are there specific times when you're not supposed to use them or there is something better to use?
Yeah, you hear this crap sometimes, especially when you are trying to parse HTML. Basically, there are modules to handle the parsing, and these modules (e.g. HTML::Parse) tend to be a very reliable and are a easy way to get the job done. HOWEVER, there is nothing wrong with using a regex. After all, Perl is optimized for regex. Many times using a regex will result in faster code than using a module. HOWEVER, most people do not fully understand regex, so they often overlook something. Basically, I love regex. Use them! Even for parsing HTML! Just make sure you know what you are doing! And have fun! But if your job is on the line, go ahead and use a module.
