How to assign mp3s to buttons loaded via xml

I have this problem. I need to assign 5 different mp3 to five differents buttons.

Im loading the path to the mp3 via an xml file.

In the kirupa tutorials i found a mp3 player that (with a little bit of editing) does what i want. I only have an inconvinient. in this mp3 player the path to the mp3 is in an attribute and i need it to be in a node value.

this is the fla working as i want with the data in attributes. ( drill_a.zip  )

And this is as far i could get loading the data from a bigger XML and with the information in values. ( drill_a_test.zip  )

The issue is in the loop to assign the sounds to the buttons. it perfoms the loop but assing the last sound to every button and only the last sound.

i really apreciate your help.
