Regex assistance

[BaseballGraphs]

I'm trying to extract several portions of a string and am having some issues.

The string is: "http://www.google.com http://www.yahoo.com http://www.facebook.co m"

I would like to extract google, yahoo, and facebook from that string.

I've been trying this:

var string  = "http://www.google.com http://www.yahoo.com http://www.facebook.com";
var several = string.match( /www.(\w+).com/g );
console.log( several );

This does not seem to be working. Can you please help me out?
Thanks!

If you are confident enough to read next string of "www." and before next . then do this

<SCRIPT>
	Query="www.yahoosadf.com";
	n=Query.indexOf("www.",0)+4;
	last=Query.indexOf(".",n);
	document.write(Query.substring(n,last));
</SCRIPT>

you could even extend your regex with more excludes like this:

var s = "http://www.google.com http://www.yahoo.com http://www.facebook.com";
var m = s.match(/[^www.|^com|^ http:\/\/](\w+)/g);
console.log(m);

<script>
var haystack  = "http://www.google.com http://www.yahoo.com http://www.facebook.com";
var urls=haystack.split(" ");
var pattern=/www.(\w+).com/;

for (var i=0; i<urls.length;i++){
    document.write(urls[i].match(pattern)[1]+'<br>');
}
</script>

Outputs:
google
yahoo
facebook
