I thought I would give your example a try, because you had mentioned ‘phantom’
DG1s, something I hadn’t seen. Well, I hadn’t used getNames before, so I was
curious.
So, yes, I did see getnames listing DG1 even when the example didn’t contain
one.
I also noticed that your example message provided earlier with have zero
entries in the List of DG1s because none of them have content in the identifier
field.
My complete code is as follows, so you can check if I made an invalid
assumption. Not I did change it somewhat.
Thanks for the opportunity to learn some more about getNames.
Printstructure is your friend. ☺

Subject: Re: [HAPI-devel] DG1 segments repetition.
James – Thanks so much for a quick response. I followed your suggestion and
added the code by calling getNames() as described below. I found that HAPI is
creating a phantom DG1 segment even when the Hl7 message does not have any DG1,
for that reason I’m doing an extra logic in the highlighted text below. Is it
intended behavior? If yes, what is the best way of handling it?
String Names[] = Msg.getNames();
List<DG1> LDGs = new ArrayList<DG1>();
for(String Name: Names){
if(Name == null || Name.startsWith("DG1") == false)
continue;
DG1 DG = (DG1)Msg.get(Name);
if(DG !=null &&
dg.getDiagnosisCodeDG1().getIdentifier().getValue()) !=null )
LDGs.add(DG);
}
Regards,
Brijesh

Subject: Re: [HAPI-devel] DG1 segments repetition.
Hi Brijesh,
You're right, the custom segments are causing an issue since the parser csn't
see subsequent DG1 repetitions as actual repetitions.
The easiest way to do this would be to call
MessageInstance.getAll("DG1")
followed by
MessageInstance.getAll("DG12")
followed by
MessageInstance.getAll("DG13")
etc.. Basically HAPI creates nonstandard segments for each of the following
DG1s by adding a sequential number to the end.
If you wanted to be more fancy, you could create a custom structure that has a
group containing the custom segment as well, or you could override the parser
and use string maniulation to remove the Z-segments before parsing.. But the
method above is definitely the least work.
Incidentally MessageInstance.getNames() will give you the names of all the
segments (including the "DG1[number]" ones) so you will know how many there are.
Cheers,
James

Hi – I’m using HAPI library(2.2) to parse the below message and calling the
method getAll(“DG1”) ( Structure[] Structs = MessageInstance.getAll(“DG1”) ) to
retrieve the DG1 segments. I’m having issues getting all DG1 segments. From the
below message, able to retrieve only one DG1 segment. Looks like the custom
segment (ZDG) is in the middle of repeating DG1 segments and breaking the
repetition.
Can you please suggest if I can use other API methods to retrieve all DG1 ( 3
in the below case) ignoring ZDG segments?
Thanks for your help.
