Question about how to change color of dynamic text

1

I am somewhat new to Actionscipt and I need a bit of help. I have created a dynamic text box that is being fed from an xml file. Depending on the data (whether positive or negative), I would like the output text to either be green or red (green for positive, red for negative). I’m sure that has to be a condition statement written and applied to the object, but I do not know how to do. Can someone advise or write the script lines in Actionscript that can achieve this? Any help with this would be greatly appreciated.
