Thanks a lot @Aillyn

Its worked for me.

I made it in the following way **

var myPattern:RegExp = /watch(?:\/|(?:\?|.*&)v=)(\w+)/ig;   
var str:String = "http://www.youtube.com/watch?&vx=123&v=Ls8ppLu72NT";
var result:Object = myPattern.exec(str);
trace(result[1]);

Try this regex:

watch(?:\/|(?:\?|.*&)v=)(\w+)

The result will be in the 1st capture group.
