Hi, All: I am using HAPI to parse HL7 message that we received from varies sources. Most message I need to process type is ORU_R01. In the OBX segment, the value type (OBX-2) always "ST", but different sources have their own custom field for the Observation Value field (OBX -5), for example :
OBX|1|ST|Custom_Field^test^test^test||comp_one^comp_two^comp_three/test^3||||||F|||20090522101333|||| Since its data type is ST I can only get comp_one. Even for same source the the components in OBX 5 is different depends on the OBR. It could be OBX|1|ST|Custom_Field^1^test^test||comp_one^comp_two^comp_three/test^3||||||F|||20090522101333|||| OBX|2|ST|Custom_Field^2^test^test||comp_one^comp_two^comp_three^comp_four/test^3||||||F|||20090522101333|||| OBX|3|ST|Custom_Field^3^test^test||comp_one^comp_two^comp_three^comp_four^comp_five/test^3||||||F|||20090522101333|||| How could I get the "comp_one^comp_two^comp_three" field? Should I create my own "datatype" or should I create my own message or should I using terse to special handle this field? Any suggestion? Thanks in advance -rockdale
