Adding your own prototype methods for built-in objects is so beautiful!
:-)
Very nice!

(Haven't tried the RegExp, though)

Hi...do this in a more elegant way...
String.prototype.trim =3D function()
	{
		return this.replace(/(^\s*)|(\s*$)/g, "");
	}

Add the code above to your script and then to trim a string just use
[string_name].trim();

Good luck.
