Its really awesome to see people sharing their knowledge to everyone out there. If you need regular expression while doing a piece of code or while doing a validation in your application, you don’t have to break your head designing this cryptic code yourself. There are awesome people out there who are good at it and they are willing to share this with the world. Recently i had a requirement to look for a particular country’s telephone number scanning through various web pages. I found a tool which does this but it had a generic regular expression for phone numbers. I am not at all good at regular expression and to be honest, i haven’t break my head trying to learn this… :).

Because i am lazy, i thought i will give in a try in Google before doing it myself from scratch. When i did, i found some very useful regular expression, all being shared and kept well in a site below:-

There is another blog which lists commonly used regular expression, not exhaustive, but worth scanning through for your requirement.

I thought before i am too lazy to share it as a blog post, i wrote a quick blog for other readers.
