Using XML as data connection, but 2 issues: Same element name, but different namespaces and Hyphens

Hi, everyone:

I'm trying to use XML based off an XSD as a Data Connection for my form.

However, when I try to use Javascript, the following prevent me from continuing further:

1. If an element has a hyphen in the name (I have removed the hyphen in the XML, but it fails to validate with the XSD)
2. If two child elements have the same element name, but are in different namespaces

I was wondering if anyone knew how to troubleshoot these issues.
