Regex for validating emails

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.

If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.

There you'll find some nice features like the SRL Query Builder which will allow you to easily generate dynamic Regular Expressions and much more. Of course, since this project is completely open source, feel free to check out the complete sources on Git Hub. We're only beginning our journey and have many things left to do.

And of course if you like, feel free to help us implementing this project in other programming languages. You could write some tests, report or squash some bugs, extend SRLs feature set, improve existing features, extend its documentation or even implement it in another language. And if you feel like this project is worth being shared, a short post about it on your favorite social media platform would be absolutely fantastic.

If it doesn't find any matches then it will fail the validation and the function will return false, if the match returns true then the email will be of a correct format and the function will return true.

This is a code snippet for basic Java Script to validate email address using a regular expression.

So let's have a look at a short example before we start. In the box below, you can see the exact same expression, but with a much cleaner syntax.

First, you'll see a boring Regular Expression as you may know them. Yes, it's quite long compared to the one on the top, but let's be honest.. Looks like we're trying to validate an email address. In this example, we'll take the SRL from above and add a few capture groups.

In the last post, I explained about java regular expression in detail with some examples.

In this real life example, I am trying to validate email addresses using java regular expression.

Can you already guess what we're trying to validate? In reality, you might not want to use a Regular Expression for that, since emails are pretty painful to validate and there are plenty of tools out there that do a way better job on that, but for our example, it fits just fine. Oh, and did we mention you can edit and explore all the SRL Queries shown on this page? All SRL Queries directly translate into basic Regular Expressions. This way we're able to filter the local part and the domain of an email address from a text.

That way you're able to create your SRL Queries on this page and use the resulting Regular Expression in any language afterwards. Okay, okay, you're validating strings in a fancy way. capture (any of (digit, letter, one of "._% -") once or more) as "local", literally "@", capture ( any of (digit, letter, one of ".-") once or more, literally ".", letter at least 2 times ) as "domain", case insensitive There are a few ways of using SRL.

On the final line we call test method for our regular expression and pass the email address as input.
