Thank you for coming to help.
That's what I did.
The routine can't get shorter than that. I attach now the xml file 
(shortest version). Just to be clear:

<?xml version="1.0" encoding="utf-8"?>
<messages>
   <message id="0">About us</message>
   <message id="1">Nothing has been ordered!</message>
   <message id="2">Continue shopping</message>
   <message id="3">Shopping cart</message>
   <message id="4">Contact us</message>
   <message id="5">News</message>
   <message id="6">Welcome</message>
</messages>

Am I referencing the nodes incorrectly?
Thank you
