Regex for email id?

[zxcvbn]

Hi,

i was trying to create a regex to find an email id on a page source but couldn't build a perfect regex for the same. Any help?

e.g. a regex to cover all these scenarios

[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]

and so on..


Thanks in advance.

[a-zA-Z0-9._%-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}

 

[zxcvbn]

Thanks.

I was able to build it to an extent but not completely correct like this one.

Anyways, didn't understand the part - {2,4} towards the end. What does this part do?

Thanks

[a-zA-Z]{2,4} = 2-4 letters after .
