Parsing text with multiple links using regex in javascript

Question

Hi im has text containing some links wrapped inside text ...

I want a regular expression (I use javascript) that can parse text and return an array of links ...

for example, for text ...

http://www.youtube.com/watch?v=-LiPMxFBLZY
testing
http://www.youtube.com/watch?v=Q3-l22b_Qg8&feature=related

regex will parse the text and return an array of links

arr[0] = "http://www.youtube.com/watch?v=-LiPMxFBLZY"
arr[1] = "http://www.youtube.com/watch?v=Q3-l22b_Qg8&feature=related"

I am trying to do this with code ...

var ytre =/(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig ;
var matches = new Array();

                    matches = ytre.exec(text);
                    var jm;
                    if (matches !=null )
                    {
                        for (jm=0; jm<matches.length; jm++)
                        {
                            console.log(matches[jm]);
                        }
                    }

but does not return the corresponding results ...

please, help

thank

Answer 1

What about:

var text = 'http://www.youtube.com/watch?v=-LiPMxFBLZY testing http://www.youtube.com/watch?v=Q3-l22b_Qg8&feature=related http://yahoo.com';

var ytre = /(\b(https?|ftp|file):\/\/[\-A-Z0-9+&@#\/%?=~_|!:,.;]*[\-A-Z0-9+&@#\/%=~_|])/ig;

var resultArray = text.match(ytre);

Take a look

To parse URLs using regular expressions, see the RFC, which defines URLs.

, , , , /\b(([^:\/?#]+):)(\/\/([^\/?#]*))([^?#]*)(\?([^#]*))?(#(.*))?/gi.
