I'd just use the String#replace method with a regular expression:

var string:String = "BlaBlaBlaDDD12345";
var newString:String = string.replace(/[a-zA-Z]+/, ""); // "12345"

That would remove all word characters. If you're looking for more complex regular expressions , I'd mess around with the online Rubular regular expression tester.

This would remove all non-digit characters:

var newString:String = string.replace(/[^\d]+/, ""); // "12345"

If you know the exact string you want to remove, then just do this:

var newString:String = string.replace("BlaBlaBlaDDD", "");

If you have a list (array) of substrings you want to remove, just loop through them and call the string.replace method for each.
