Dynamic binding expression to get data from array

Question

I am retrieveing from an object to label my button as
follows:
quote:
<mx:Button label = "{wordlist.word.LABEL[0][index]}"
I now want the binding expression to be dynamic, meaning that
LABEL has to be a variable. How would I do this?
quote:
<mx:Button label =
"{wordlist.word.????[LABEL]????[0][index]}"

First, if wordlist.word.LABEL is an XMLListCollection or
ArrayCollection,
you need to use getItemAt instead of bracket notation. Once
you get to that
point, you need to cast it to whatever data type the object
at 0 is.
