Enrich soap message with ESQL - soap

Question

I am creating a simple flow that receives a message via SOAP and in IIB I treat the message with ESQL.
This is my SOAP message:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:com="http://ComponentesTI">
<soapenv:Header/>
<soapenv:Body>
<com:PushMessageRequest>
<Message>
<SerializedContent>?</SerializedContent>
<HTTPAddress>?</HTTPAddress>
</Message>
<Identification>?</Identification>
</com:PushMessageRequest>
</soapenv:Body>
</soapenv:Envelope>
I need to replicate this message just by changing the Identification field using ESQL (using a GUID)
Something like that:
CREATE LASTCHILD OF OutputRoot DOMAIN 'XMLNSC';
DECLARE statement REFERENCE TO OutputRoot.XMLNSC;
DECLARE statement2 REFERENCE TO InputRoot.XMLNSC;
SET statement = statement2;
SET statement.PushMessageRequest.Identification = UUIDASCHAR;

Answer 1

You forgot to use XML namespace in the ESQL syntax.
CREATE LASTCHILD OF OutputRoot DOMAIN 'XMLNSC';
DECLARE statement REFERENCE TO OutputRoot.XMLNSC;
DECLARE statement2 REFERENCE TO InputRoot.XMLNSC;
SET statement = statement2;
DECLARE com NAMESPACE 'http://ComponentesTI';
SET statement.com:PushMessageRequest.Identification = UUIDASCHAR;

Answer 2

The code fragments below take into account the SOAP Envelope.
Copy everything including the Properties folder and any other Header folders and then change the Identification field.
SET OutputRoot = InputRoot;
SET OutputRoot.XMLNSC.*:Envelope.*:Body.*:PushMessageRequest.Message.Identification = UUIDASCHAR;
Create a new XMLNSC aggregate with other code handling the Properties folder and other headers as required.
CREATE LASTCHILD OF OutputRoot DOMAIN 'XMLNSC';
SET OutputRoot.XMLNSC.*:Envelope.*:Body.*:PushMessageRequest.Message.Identification = UUIDASCHAR;
Also depending on whether you are using an HTTPInput vs a SOAPInput Node the top level aggregate may be SOAP rather than XMLNSC.
Lastly as we aren't changing any of the namespaces and are overwriting the value in Identification I used the syntax *: for the namespace so I didn't have to declare the namespace variables for soapenv and com
