[HAPI-devel] Please help a neophyte with a parsing problem

[Elliott F. <efa...@co...>]

Hi all:

I'm just starting to learn the HAPI interface.  I applaud your efforts =
and hope that I will be able to contribute to this project some day.   =
For now, though, I just need some help in learning how to use the API.   =
My eventual goal is to extract data from ORU^RO1 messages for the =
purposes of assigning ICD9 codes to discharge summaries.   The discharge =
summaries are embedded in an ORX segment and for now I'm just trying to =
figure out a way to extract the needed data and copy it to a String so =
that I can process it.   I tried modifyng the ParserDemo program (which =
I was able to succesfully run) by assigning an input stream to a message =
and then trying to get the OBX segment (i.e. Structure structure =3D =
message.get("OBX");) my thinking being that if I can get the relevant =
segment then I can get to the field I need.   No such luck. I get an =
error message saying that there is no such structure as an OBX when I =
run the program (but of course there is).   I've tried this both on some =
sample data obtain from a local hospital and with the sample files I =
downloaded with the .4.1 HAPI release that came from Duke.    I know I'm =
missing something fundamental.   I've read that message structures are =
very different and I know the HAPI API has some way to deal with this, =
but I haven't to date, been able to put the pieces together.   Could =
someone out there help me along?  An explanation or some sample code (or =
both!) would be great.

Thanks in advance for any help provided.

Regards,

Elliott
