Question

How can I parse a HL7 message starting with FHS to XML:

Was it helpful?

Solution

First of all your message has to starting segments (FHS and also the MSH) - so it may be recognized as two messages.

And Unfortunately with the basic HAPI Library this is not possible as HAPI does not know the FHS segment. When you use the HAPI TestPanel you'll see the result quite clear:

enter image description here

When you switch to the XML View - HAPI was able to convert the ORU message (starting with the MSH), but the first line (FHS) is still there.

Solution A: (IF you cannot modify the source HL7) Parse the "FHS" yourself into the XML format you want. And then you can use HAPI to convert the rest for you.

Solution B: Change the HL7 file and add your segments at the end. Then HAPI converts it. Example HL7:
