CPI - Send message separating by employee

Hello experts!

I need to send data from Success Factors to SAP ERP, separated by employees.

Example: I submit a request reply to the "BenefitEnrollment" entity, where it returns a XSD with multiple employee benefits, and I need to send it to SAP ERP in separate messages divided by the same employee ID presents in the element workerId. Could someone help me how to do this? I tried to use SPLIT but it only separate the message with fixed value, I believe this should not be the correct way.

Here is my XSD:
