Answer 1

var subject =
'<link rel="shortcut icon" href="https://cdn.sstatic.net/Sites/stackoverflow/img/favicon.ico?v=ec617d715196"><link rel="apple-touch-icon" href="https://cdn.sstatic.net/Sites/stackoverflow/img/apple-touch-icon.png?v=c78bd457575a"><link rel="image_src" href="https://cdn.sstatic.net/Sites/stackoverflow/img/apple-touch-icon.png?v=c78bd457575a">';
var re=/\"[a-z]+:\/\/[^ ]+"/m;
document.write(subject.match(re));

You can try this

/\"[a-z]+:\/\/[^ ]+/

Usage

if (/\"[a-z]+:\/\/[^ ]+/m.test(subject)) {  // Successful match } else {    // Match attempt failed }

In case if you need this for your JavaScript web-app: the best answer I ever found on this topic is here. Basic (and also original) version of the code looks like this:

var parser = document.createElement('a');
parser.href = "http://example.com:3000/pathname/?search=test#hash";

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "3000"
parser.pathname; // => "/pathname/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"
parser.host;     // => "example.com:3000"

Thank you John Long, you made by day!

Its not a regex solution, but most languages have a URL library that will parse any URL into its constituent parts. This may be a better solution for what you are doing.
