pythonhl7

How to correctly parse an HL7 message using python HL7Apy?

Here is my code:

from hl7apy.parser import parse_message

hl7 = open("hl7.txt", "r").read()
msg = parse_message(hl7)
print(msg.children)

result:

[<Segment MSH>]

It shows only the first segment, seems simple but I don't know what i'm doing wrong.

I've tried from a text file, passing the message directly or even with another HL7 message, but always got same results.

Here is the message:

MSH|^~\&|SendingAPP|TEST|||20080617143943||ORU^R01|1|P|2.3.1||||||UNICODE
PID|1||7393670^^^^MR||Joan^JIang||19900804000000|Female

Here is my message in notepad++ where all characters are shown: Message in notepad++

Solution

  • by disabling find_groups like this msg = parser.parse_message(hl7, find_groups=False) My messages are now parsed correctly.

    Thx to @sqlab and @badger0053 for help, i was able to make a progression.
