Can't get multiple OBXs of an OBR in HL7 2.5.1



Im using the 2.5.1 API and my test message has an OBR and 2 OBX, I only can inquiry the first OBX.

Does anyone can help me?

Thanks in advance,

I just checked by creating a sample message for V2.5, with multiple OBX segments and have been able to iterate over the results.

I'm guessing the confusion here is just the rather ... interesting method required to iterate over the results

Here's some sample code for you to look at, this should at least point you in the right direction hopefully :-)
var parser = new PipeParser();
var oru = new NHapi.Model.V25.Message.ORU_R01();    
oru = (NHapi.Model.V25.Message.ORU_R01)parser.Parse(GetMessage());

var repetitions = oru.GetPATIENT_RESULT(0).GetORDER_OBSERVATION(0).OBSERVATIONRepetitionsUsed;
for (int i = 0; i < repetitions; i++)
    foreach (var obx5Value in obx.GetObservationValue())
        var typed = obx5Value.Data as Model.V25.Datatype.FT;
        var typedValue = typed.Value;
Hope this helps!

Thanks for your response.

Yes with a 2.5 Message version works perfectly, the problem is with the dll version 2.5.1

My apologies, I thought you were referring to the 2.5 dll.

I can see that there in fact appears to in fact be a problem with the generated code for the v2.5.1 dll.

Thank you for raising this.

I'm hoping to get access to the later versions of the HL7 specification databases soon (2.6+), so I'll look into this further once I've obtained the specification databases to work with.
