Not getting later values from the HL7 response

[tao-prabal-tiwari]

I am trying to get values like message.get("ORC.9.1").toString() but for several values I am getting null value even when these values are present in my HL7 Text.

Please provide an example HL7 message and path string that returns null and I'll take a look. Thanks.
