Infopath 2013/REST Web Service - XML Data format

I've created an Infopath 2013 form and connected it to an existing REST Web Service. The form connects successfully, but I can't get to the nodes that contain the actual data. The REST results look like this:

<wddxPacket version='1.0'><header/><data><struct><var name='MIDDLENAME'><string>S</string></var><var name='FIRSTNAME'><string>John</string></var><var name='UID'><string>jdoe</string></var><var name='EMAIL'><string>jdoe@mycompany.com</string></var><var name='DEPARTMENT'><string>IT ADMINISTRATION</string></var><var name='TITLE'><string>Director</string></var><var name='LASTNAME'><string>Doe</string></var></struct></data></wddxPacket>

When I connect to the web service in InfoPath, here is what I see:

Notice that when we expand the tree, it only shows the "struct" node. How do I get down to the actual data fields?

Thanks in advance.
