How can I validate an email address using a regular expression?
(79 answers)
Closed 7 years ago.
I am trying to extract all the email addresses from pages like this
http://www.quiltguilds.com/alabama.htm
I am using the following RegEX to extract all the emails.
\w+#\w*\.\w*
While this works at online Regex checkers, this isn't working with the import.io application where I am trying to use this to extract all emails.
Can someone kindly review the Regex and confirm if this one would work for extracting just email addresses from a block of text
Many thanks
You can use the following regex:
\S+\#\S+

How can I validate an email address in JavaScript?

I want to validate all email inputs on my app with regex. But there is a problem, all the regex I have found allow emails with no TLD. I want a regex that can help me reject emails such as testing#testing,
Examples:
testing#testing.com should be valid
testing#testing.co.us should be valid
testing#testing should not be valid
The current regex I use is :
^([a-zA-Z0-9_-.]+)#(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.)|(([a-zA-Z0-9-]+.)+))([a-zA-Z]{2,4}|[0-9]{1,3})$
But it accepts testing#testing for example, and that is not what I want.
How would I go about validating emails and rejecting ones without TLD
This is the regex which does what you want:
[A-Za-z0-9._%-]+#[A-Za-z0-9._%-]+\\.[a-z]{2,3}

I came up with the following
([\w.%+-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4})
I would also like to remove emails that start with a number or -. By remove I mean to select only the address and not to remove the entire match.
Is there a way to do that?
^(?:\d+|-+)?([\w.%+-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4})$
This should do the trick. It'll capture emails but also filter out ones that start with a number or the - character and pulls the email from it.

I want an regex for email that starts with numbers and letters.
My regex is
/^[a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/
What is wrong in this? It allows ._- from start and in between. But I don't want this
Valid emails = s#gmail.com, s.p#y.com, s_p123#g.com
Invalid emails = ....s#g.com, s---g#g.com, s...#g.com, 44s..p#g.com, ----s#g.com
Does anyone know how this can be done?
So you dont want to have more than one ._- in your regex? And also it shall not start with ._- Try it this way:
^[a-zA-Z0-9]+[._-]?[a-zA-Z0-9]*#[a-zA-Z0-9.-]+.[a-zA-Z]{2,4}
It works for your examples, although im not really sure what email-syntax you really want to test for.
Perhaps you want to use one of many pre written examples in the web (just google ;) )

I have a JAVA string that is being used to validate proper email addresses.
^[\\w'-]+(\\.[\\w'-]+)*#[A-Za-z0-9]+([.-][A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$
I want to user to be able to leave the address blank and not get an error message. How is this possible?
Since you didn't provide any other code or specify what language you were using, the best I can suggest is:
(?:^[\\w'-]+(\\.[\\w'-]+)*#[A-Za-z0-9]+([.-][A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$)|(?:^$)
Which will match an e-mail or an empty string.
If you have an expression you want to make optional allowing empty string to match you could use any of the following:
^(?:regex)?\z
^\z|^regex\z
