TSQL XML Namespaces

I am trying to get the data from an XML file that has Namespaces
.
I can't seem to get the syntax correct .. I only return Blank Fields
.
If I edit the XML file removing the soap:envelope, soap:body, and getrfqresponse  .. then I can get to the data
the Namespace declaration is messing me up
the soap:body & the child namespace in GetRFQsResponse are problems I am having including with the namespace
.
