[SOLVED] Extract email address from string

Extract email address from string

I have a string like this:

Francesco Renga <francesco_renga-001@gmail.com>

I need to extract only the email, i.e. francesco_renga-001@gmail.com.

How can I do this in nodejs/javascript in "elegant" way?

Solution

Here's a simple example showing how to use regex in JavaScript :

var string = "Francesco Renga <francesco_renga-001@gmail.com>"; // Your string containing
var regex = /<(.*)>/g; // The actual regex
var matches = regex.exec(string);
console.log(matches[1]);

Here's the decomposition of the regex /<(.*)>/ :

/ and / are mandatory to define a regex
< and > simply matches the two < and > in your string
() parenthesis "capture" what you're looking for. Here, they get the mail address inside.
.* : . means "any character", and * means "any number of times. Combined, it means "any character any number of times", and that is inside < and >, which correspond to the place where the mail is.
