Source Code
require 'hl7.serialize' function main(Data) Msg, Name = hl7.parse{vmd = 'example\\demo.vmd', data = Data} -- the examples demonstrate how to use hl7.serialize{{} -- NOTE: you will need to customize the code to use delimiters -- and/or escape characters to match your requirements -- use default delimiters local Out = hl7.serialize{data = Msg} -- use non-standard delimiters Out = hl7.serialize{data = Msg, delimiters = {'\n', '#', '.', '&', '\'', '*'}} -- use different non-standard delimiters Out = hl7.serialize{data = Msg, delimiters = {'A', '|', '^', '~', '\\', '&'}} -- use non-standard escape characters (to escape delimiters) Out = hl7.serialize{data = Msg, escaped = {'A', 'B', 'C', 'D', 'E'}} -- use non-standard delimiters and escape characters Out = hl7.serialize{data = Msg, delimiters = {'\n', '&', '\\', '}', '~', '^'}, escaped = {'A', 'B', 'C', 'D', 'E'}} -- transmit the messsage: -- - push message to queue then send with LLP Client -- - push to a web service -- - etc end

Usage Details
Have you ever needed to generate an HL7 message with non-standard delimiters? Sometimes the receiving party is expecting their own flavor of HL7 with strange delimiters, so what do you do? You can use this function, hl7.serialize{}
, which will serialize an HL7 message with a provided set of delimiters (and/or a provided set of “escape characters”).
How to use the code:
- Use a Filter or To Translator script
- Add the code
- Add the hl7.serialize.lua module
- Load the sample messages from SampleData.txt
- Alternatively you can also load the attached project that contains the module and sample messages
- Inspect the code and annotations to see how it works
