removing multiple segments via transform

[tmartinac]

I have a channel that receives HL7 ORM messages that sometimes have multiple ORC, OBR, and OBX segments. I want to only keep the 1st of each segment. They are also not stacked; usually goes ORC, OBR, OBX and then the next set.

I tried something like this:

while (msg['ORC'].length() > 1)
{
delete msg['ORC'][1];

but it is not removing the extra segments

post sample messages with a before and after.

[pacmano1]

That is the before message - what do you expect for the after message?

Also please use code bloicks

var obxs = getSegmentsAfter(msg, msg['OBR'][0], 'OBX', 'OBR') 
msg.ORC = msg['ORC'][0] 
msg.OBR = msg['OBR'][0]
delete msg.OBX
obxs.forEach(function(obx) {
    msg.appendChild(obx);
});
