Error reading multiple OBX

[skrugg]

I'm sure this is a total newbie question, but I can't figure out what I'm doing wrong.

I'm reading a message with multiple OBX segments like this:

MSH|^~\&|MGRM-HL7|MGRM|MGRM_APP|MGRM_FAC|200612121023||ORU^R01|7 10|D|2.3

OBX|8|ST|ABC-PSGT^Abacavir Net Assessment||||||||X|||||||
OBX|9|ST|AMP-PSGT^Fosamprenavir Net Assessment||||||||X|||||||

As a test in my transformer, I'm just trying to read the OBX line numbers into a variable:

var test

for (obx in msg..OBX){
	test += obx['OBX.1']['OBX.1.1'].toString() + ',';
}

...which results in the error, "Cannot read property "OBX.1.1" from undefined"

Can someone point me in the right direction?

Thanks!

Thanks, nshaik! It works with this code:

var obxi = 0;
var test

while (msg['OBX']['OBX.1']['OBX.1.1'][obxi] != null) {
	test += msg['OBX'][obxi]['OBX.1']['OBX.1.1'].toString() + ',';
obxi++;
}

But I'm still not clear why the "for" construct doesn't work. It fails with the same error even if I test for null.

var test

for (obx in msg..OBX){
	if(obx['OBX.1']['OBX.1.1'] != null){
		test += obx['OBX.1']['OBX.1.1'].toString() + ',';
	}
}

Re:Error reading multiple OBX

I'm guessing that you should be using a 'for each' loop rather than a plain for?
