Using XMLDataSource to read XML files with Namespaces

Hi!
I am trying to utilize XMLDataSource in order to process XML files.
The issue is that if an XML file contains any namespaces, the application stops working.

For example, the following XML file works fine:
<?xml version="1.0" encoding="iso-8859-1"?>
<orders>
   <order>
     <customer id="12345" />
     <customername>
         <firstn>John</firstn>
         <lastn>Smith</lastn>
     </customername>
     <transaction id="12345" />
     <shipaddress>
         <address1>1234 Tenth Avenue</address1>
 &nb ...
