Re: [HAPI-devel] DG1 segments repetition.

[Singh, B. <Si...@ad...>]

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);
                }

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.
