I’ve written some code that creates four buttons and assigns their labels from an xml file. Unfortunately, the way it works there’s hardly any point of bothering with xml because I just have to write out each TweenButton instance name, its initial parameters, listeners, inclusion on the display list, etc, all within the createTheButtons function anyway. All in all it seems a very bloated and ineleagant way of doing it and I would like to make it more dynamic and scaleable.
For starters, how can I condense everything that’s presently in the createTheButtons function into a for loop, have it increment through __buttonLabelsXML, and use its index to dynamicaly name each Tween button instance, set its initial parameters and listeners and add it to the display list?
I know it’s a lot to ask, but could someone please show me? 
Here’s my code and source files:
