I’m not sure about the first two, but I have done some work similar to your
3rd point.
It’s usually outside of the scope of a message parsing library to validate
the contents of a message, they only validate the structure. Another caveat
is that there are many coding systems each with its own formats and
licensing issues.

*Subject:* [HAPI-devel] Checking the integrity of the fields
Hi,
Does someone know if it is possible with Hapi to check the content of HL7
message fields ? I know that the default validator checks if required fields
are filled, and that it has some patterns to validate that the fields format
is correct. But I would like to check soem other things, such as :
- the unicity of OBX-1 in the message (for example the first OBX segment has
"1" in its OBX-1 field, the second has "2", etc)
- the coherence of hierarchical identity in OBX-4 ("1.0.0.1", then
"1.0.0.2", etc)
- checking if a CWE-2 subfield is part of the coding system defined in
CWE-3 subfield.
I guess I'm not the first person trying to do this, so I wonder if something
already exists for this type of validation.
Thanks for your help.
