RegularExpression help

ok guys, need help
I want to extract Youtube video ID
It comes in 2 possible variations. in the example below the video id is ibvwUyeKe8c
http://www.youtube.com/watch?v=ibvwUyeKe8c
http://www.youtube.com/v/ibvwUyeKe8c

Now i need a regular expression in JAVASCRIPT, that will extract the video id from the above strings
So i'm looking for what comes after v= and v/ and before & or eol


Good luck :)

avcourse i will extend it to Google video as well

    Got it /(?<=v(=|\/))([A-Za-z0-9-]+)/g and /(?<=docid(=|\/))([A-Za-z0-9-]+)/g and this to catch both /(?<=(v|[docid])(=|\/))([A-Za-z0-9-]+)/g Is it a bad idea to catch both google video and youtube with one expression

    this works on o9, ff2 and ie7:
    function find_videos(str)
    {
    	var t, reg, vids, i, type;
    	
    	reg = /\/(watch\?v=|v\/|(googleplayer.swf|videoplay)\?docid=)([A-Za-z0-9_\-]+)/igm;
    	vids = Array();
    	RegExp.lastIndex = i = 0;
    	
    	while( (t = reg.exec(str)) != null )
    	{
    		if(t[2] != undefined) type = 'googlevideo';
    		else type = 'youtube';
    		
    		vids[i++] = { 'type' : type, 'id' : t[3] };
    	}
    	
    	return vids;
    }
