Problems managing message information

[asulis]

Hi to all,
i have a bad problem trying to scan all OBR-ORC segments of an HL7 message.
I have a message like this:

I try to extract all ORC-OBR pairs and to get some values from them in this way:

 var orm_path = 'ORM_O01.ORCOBRRQDRQ1ODSODTRXONTEDG1RXRRXCNTEOBXNTECTIBLG';


 for (var k=0; k<msg[orm_path].length(); k++) {
	logger.info(&#039;PRINTED k key:&#039;+k+msg[orm_path][&#039;ORC&#039;][&#039;ORC.3&#039;][&#039;EI.1&#039;][k]);
	logger.info(&#039;PRINTED k value:&#039;+k+msg[orm_path][&#039;ORC&#039;][&#039;ORC.2&#039;][&#039;EI.1&#039;][k]);

}

this is what I read from logger:

  PRINTED k key:047889
  PRINTED k value:02070038266.4
  PRINTED k key:147891
  PRINTED k value:12070038266.1
  PRINTED k key:247892
  PRINTED k value:22070038266.2
  PRINTED k key:347893
  PRINTED k value:3undefined
  PRINTED k key:447894
  PRINTED k value:4undefined

As you can see, while ['ORC']['ORC.3']['EI.1'] follows the correct order, ['ORC']['ORC.2']['EI.1'] do not. This is a
very bad problem for me, because I can't use the k index in order to manage message information correctly.
where is the problem? Could this be a bug?

Thanks to all,
asulis

Re: Problems managing message information

Should'nt be;

  logger.info('PRINTED k key:'+k+msg[orm_path]['ORC'][k]['ORC.3']['EI.1']);
  logger.info('PRINTED k value:'+k+msg[orm_path]['ORC'][k]['ORC.2']['EI.1']);

Or:

logger.info('PRINTED k key:'+k+msg[orm_path][k]['ORC']['ORC.3']['EI.1']);
  logger.info('PRINTED k value:'+k+msg[orm_path][k]['ORC']['ORC.2']['EI.1']);

Thank you very much. Now all transformations seem to work properly.
