Ok.

>Then, I was getting the error 500 because the SOAPAction was missing.

Ok, also. It means the SOAP Web Service is 1.1, not 1.2. That should have been derived from the WSDL, missed that.

>Then, I was getting an error doing the selectNodes because the namespaces were wrong.

Er... this is the part I don't understand. The namespace used for node selection is the same in both my post and yours...
