initial caps in actionScript using Regex

Question

I'm trying to do initial caps in actionScript with no loops but now i'm stuck. I wanted to select the first letter or every word then apply uppercase on that letter. Well I got the selection part right, but at a dead end right now, any ideas? I was trying to do this with out loops and cutting up strings.

//replaces with x cant figure out how to replace with the found result as uppercase

            public function initialcaps():void 
            {
    var pattern:RegExp=/\b[a-z]/g;
    var myString:String="yes that is my dog dancing on the stage";
    var nuString:String=myString.replace(pattern,"x");
    trace(nuString);
   }

Answer 1

Try to use a function that returns the uppercase letter:

myString.replace(pattern, function($0){return $0.toUpperCase();})

This works at least in JavaScript.
