I want to modify the WSDL file, say "soap:address" element in it.
<service name="SessionCreateRQService">
<port name="SessionCreatePortType" binding="tns:SessionCreateSoapBinding">
<soap:address location="https://webservices.sabre.com"/>
</port>
</service>
once it is done, pass the modified WSDL file during SOAP Request Calls.
Thanks
Finally found it.
all you need to do is, pass location as a parameter while making a client call.
Client(URL, location='https://sws-crt.cert.sabre.com/')
No need of editing the WSDL file
