Hi Tom,
The SIU_S12_.. structure is actually a segment group. Chapter 3 of the HL7=
=20
spec defines the SIU messages as containing the following structure:=20
[ { PID [PD1] [PV1] [PV2] [{OBX}] [{DG1}] } ]
which basically means that the entire chunk of segments is optional (as=20
indicated by the surrounding [ ]) and can repeat as a group (as indicated b=
y=20
the surrounding { }).
To access the PID segment, use notation like:
terser.get("/SIU_S12_PIDPV1PV2OBXDG1/PID-3");
This long name actually maps to a HAPI class by the same name.
Does this make sense?
Cheers,
James Agnew
