How to detect links in text automatically

Question

I'm working on Twitter client app and I want the URLs or links in the statuses behaves like a link.  I saw AIR apps like TweetDeck, DestroyTwitter and Twhirl which they show links as links though.

I've found a way at http://bit.ly/9OKEUl using regular expressions I'll test it now and hope it works.
Here is the way:
You could replace the URLs in your text for actual links using the following regex:
str = str.replace(/((https?|ftp|telnet|file):((\/\/)|(\\\\))+[\w\d:#@%\/;$()~_?\+-=\\\.&]*)/g, "<u><a href='$1'>$1</a></u>");
Then set the htmlText on a Label or Text component and listen for it's link event:
<mx:Text htmlText="{str}" link="linkHandler(event)"/>
Then open the URL on the handler:
public function linkHandler(event:TextEvent):void {
    navigateToURL(new URLRequest(event.text), '_blank');
