Actionscript 2.0 Search xml attribute to print its value

I have an xml (attached at the end of the message) and i need a flash as2 file with a dynamic text field to show the value of the attribute PriceA based on the Codigo attribute. Right now im loading the PriceA values on textfields based on its position using [login to view URL][0].[login to view URL]; But if i add, delete or move a child from its original position all my values change. I need to be able to define a textfield content based on its Codigo attributes and not based on his position. So just by changing the Codigo value on the Actionscript i can change the .text content of the textfield. This is the example XML. <?xml version="1.0" encoding="iso-8859-1"?> <Productos> <Linea Codigo='2012' Descript='Comb1 1/4 lb s/queso' PriceA='3100' /> <Linea Codigo='2013' Descript='Comb2 1/2 lb Dble c/Queso' PriceA='3650' /> <Linea Codigo='2464' Descript='Combo 1/4 Promo(Ave)GD' PriceA='2800' /> </Productos> Thanks, I need this fast please.
