MSH|^~\&|REG|XYZ||XYZ|20050912110538||SIU^S12|4676115|P|2.3
PID|||353966||SMITH^JOHN^^^^||19820707|F||C|108 MAIN STREET ^^ANYTOWN^TX^77777^^|HARV|(512)555-0170|||||00362103|123-45-6789||||||||||||

NK1|0002|HULK^DEBATEABLE|M|122 FAKE ST^^OUTLAND^^00000|123456789||

And the javascript:

parser = require('L7')

message = parser.parse(hl7)
version = message.query('MSH|12') // 2.3
kinAddresses = message.query('NK1[4]') // ['123 FAKE ST^^OUTLAND^^00000', '122 FAKE ST^^OUTLAND^^00000']
kinStreets = message.query('NK1|4[0]') // ['123 FAKE ST', '122 FAKE ST']

name = message.translate({
  familyName: 'PID|5^0',
  firstName: 'PID|5^1'
}) // { "familyName": "McTest", "firstName": "Test" }

message.toString() // returns original message
message.replace('PID|5', 'McFake', 'Firstname'); // replaces the values in the message with the supplied ones
message.replace('PID|11^0', '123 Fake Street'); // can replace just one element

message.remove('PV1'); // removes the PV1 segment if it exists
message.remove('IN1', 'IN2'); // removes the IN1 and IN2 segments if they exists
message.remove('Z*'); // remove all "Z" segements
