Topic: HL7 message custom validator

I need to write a custom validator for HL7 message

Input:

MSH|^~\&|Sample.GateWay||||202002061359||ORU^R01|5678|D|2.3
PID|1|CPHC0040||789987|Deshmukh^Darshana||20100717|F||
ORC|NW|||||||||||||||||||
OBR|||||||202003051359|||||||||||||||202003051359|||||
OBX||NM|81894-8^CAP||175|dB/m|100-260|||N|F|||202004041359|BN
OBX||NM|77615-3^E|||kPa||||||||202004041359|BN

Validator to check some fields are not empty like,

public class MsgHL7ValidationBuilder extends ValidationRuleBuilder {

private final Logger log = LoggerFactory.getLogger(MsgHL7ValidationBuilder .class);

 @Override
 protected void configure() {
     log.info("Entering MsgHL7ValidationBuilder ...");
     super.configure();
     forVersion(Version.V23)
     .message("*", "*")
     .terser("MSH-10", not(empty()))
     .terser("/.OBX-2", not(empty()))
     .terser("/.OBX-3", not(empty()))
     .terser("/.OBX-5", not(empty()))
     .terser("/.OBX-11", not(empty()))
     .terser("/.OBX-14", not(empty()));

     log.info("Exiting MsgHL7ValidationBuilder ...");
 }

}

Now, in this case validator works fine for the first OBX segment, but it dows not work for second or further OBX's.

I need to handle this if there are 'n' number of OBX's.

Any help would be really appreciated.

Thanks,
Sheetal
