Re: [HAPI-devel] ORM 001 and XML

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

In reverse order:

3) LAT is not part of the ORM structure, it is an artifact of the 
segment being wrapped by the email:

OBR||LL02-194182|(963)232-25AF|71020^CHEST PA 
LAT||20020920||||||||||455^JONES^JOHN|(914)632-9422

is one line with "|71020^CHEST PA LAT|" being field 5

2) OK. I wanted to use XML to do various transformations with XSLT...but 
if people don't use the XML much perhaps there is a reason and I should 
consider do the transformation in pure Java.

1) Perhaps I don't know as much as I thought, but how can I specify the 
message structure more explicitly than have ORM^O01 as MSH-9? And what 
is MSH-9-3, I have only seen two subfields in MSH-9, not three. Perhaps 
I am misunderstanding.

Many Thanks
