如何使用Python-HL7工具验证HL7消息？

Question

I am using Python-HL7 tool.

After receiving message from server, I want to validate the message and send back acknowledge message if message received is valid or not.

hl7.ishl7() method only does a cursory check and does not fully validate the message. How can I actually validate the message?

Answer 1

Parsing and Validating are two different things. You mentioned hl7.ishl7() which just parse the HL7 message.

Following is from documentation :

 hl7.ishl7(line) 

Determines whether a line looks like an HL7 message. This method only does a cursory check and does not fully validate the message.

Many HL7 tool kits (in other languages I know) provide feature for validating the message; but apparently, this specific toolkit does not.

Validating the HL7 message may be personal choice as well in addition to specifications. Generally, you should first parse the message (using hl7.ishl7(line) ) and then should implement validation code on your own. This way, you may include the validations specific to your application/need.
