hl7lw 0.1.0

Super light weight Hl7 2.x parser

hl7lw: A Lightweight HL7 2.x Parsing Library

The hl7lw library aims to provide an extremely simple and lightweight API to read, modify, and write HL7 2.x messages. Minimal processing is done to the messages and most data access should feel very natural and pythonic.

import hl7lw

p = hl7lw.Hl7Parser()
m = p.parse_message(message_bytes)

if m["MSH-9.1"] == "ORU":
    m["ORC-1"] = "RP"

message_bytes = p.format_message(m)

report = "\n".join([obx[5] for obx in m.get_segments('OBX') if obx[2] in ('TX', 'FT', 'ST')])

c = hl7lw.MllpClient()
c.connect(host="127.0.0.1", port="1234")
c.send(message_bytes)
ack_bytes = c.recv()
c.close()

ack_m = p.parse_message(ack_bytes)
assert ack_m["MSA-1.1"] == "AA"
assert m["MSH-10"] == ack_m["MSA-2"]
