This is on Oracle9i Enterprise Edition Release 9.2.0.6.0 - 64bit Production

'xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"'
v_resp :=
resp.EXTRACT ('NewOrderResponse/return/text ()', '"approvalStatus"').getstringval
Not sure where Am I doing wrong. Please help
Thanks,

Answer 1

Okay, I have removed the "ApprovalStatus" and replaced with the xmlns. Also, based on the description of child:node(), I think, then it is required.
Now I am getting following error
ORA-30625: method dispatch on NULL SELF argument is disallowed
Below is the complete code and underneath code I am providing response XML structure
