Remove spaces from array

I have an array of 13 items (all of which are letters EX e,e,e,e ...).  It is being read in from a database.  However, I want to loop through the array and clean out any spaces that it might have.  I am having trouble doing this.  Anyone done this before?

Here is what I have so far.

outputBox.autoSize = TextFieldAutoSize.LEFT;

displayArray(system.selectedAnswers.length);

function displayArray(n:int):void {

    for (var i:int = 0; i < n; i++)

    {

  system.selectedAnswers.replace(/^\s+|\s+$/g, "");

  outputBox.appendText(String(system.selectedAnswers) + ",");

    }

}

Thanks.
