Need help on XPATH in CPI

Hi Experts,

I have to capture a value (ZRQ) from the incoming message but, not able to capture.

Tried relative & absolute xpath with all combinations but no luck.

Could you please suggest if I am missing anything here.

Tried the below:

/soap-env:Envelope/soap-env:Body/n0:SalesOrderRequestMassRequest/SalesOrderRequestRequest/SalesOrderRequest/n1:Z_RefQuoteDocType

//Z_RefQuoteDocType
