regex expression logic [closed]

Question

Regex expressions seems cocumbersome, they always drive me mad when trying to build it up. And i end up asking for help. But once i am given the result it looks really coool. Gurus, is there a way to go about it to break it up.

Answer 1

Yuo can start with tutorials at Regular-Expressions.info which provide a good starting point. The reference there is also invaluable as are the explanations how the regex engine works behind the scenes.

Actually, the fundamentals aren't that hard to grasp and once you got them it's not too hard. However, reading complex regular expressions is more like an arcane art; it can get pretty unwieldy quickly.
