object.mrn = msg['PID']['PID.3']['PID.3.1'].toString();
object.firstName = msg['PID']['PID.5']['PID.5.2'].toString();
object.lastName = msg['PID']['PID.5']['PID.5.1'].toString();
object.dob = msg['PID']['PID.7']['PID.7.1'].toString();
object.ssn = msg['PID']['PID.19']['PID.19.1'].toString();

//Create string from JSON Object.
var objjson = JSON.stringify(object);
logger.info(objjson);

//Create Json Object From JSON string.
var tt = JSON.parse(objjson);

Output

Answer 2

I was parsing through this page, and found your code Rikin patel. Actually when You create object and display it, it may appear in the console as a JSON data, when when you look your output it will be the normal XML driven format. But instead of the object when you use msg as below:

msg = JSON.stringify(object); //converting msg into JSON object
logger.info("json data:" + msg); //displaying the JSOn message

You will find the data being modified in the output.
