Getting some SOAP value with XPATH with check and SaveAs

Hi, I’ve a lot of troubles to get a value that come from a SOAP service.
Reading this message: https://groups.google.com/forum/#!topic/gatling/gfAXCbXSKz0
I tried to figure my task but is not working neither.

My check:
.check(xpath("/env:Envelope/env:Body/ns1:EResponse/ns1:NumeroUnicoSiris", List(“env” → “http://www.w3.org/2003/05/soap-envelope”, “ns1” → “siris.autorizador.ws”)).saveAs(“branchID”))

The SOAP response:

HTTP response:

NumeroUnicoSiris is not in the ns1 namespace in your SOAP payload.
