Hi Vishal, 
 
Yes, people put messages in files in all kinds of wierd ways.  How about
scanning the file using some kind of regular expression that will find
messages amid arbitrary content.  Like this maybe:
MSH(.).*\r\n?([A-Z]{3}\1.*\r\n?)*   (I don't know if that one will work --
just trying to illustrate).   
 
Or you could hack the MLLP code to use delimiters that you set at run time.
I think I did that once.   If I remember correctly there was some trick to
using escape sequences outside of Java source (you would want to do this so
you could easily type them into a config file or on the command line using
characters you have on your keyboard).  Nope, it's not coming to me.

Yes, messages in the file. Whenever we develop interface for somebody,
usually they send us the files as a specification.

 

Would that be different?

Hi Vishal, 

Vishal Answer: Really? I am actually surprised. Since yesterday I collected
six sets of HL messages from some from our customers ( real time data,5-10
messages) and actually one of the files have standard start message
character   '\u000b'  but most of the time message end  varies with  '0D 1C
OA' ,'0D 0A 1C 0D 0A',atleast '1C' is usually consistent . One of the sets
had only '0D' as start and end with '0D' again. I have been dealing with
customer all over US and yes, we did have problems with our HL7 parsing
usually ended up in custom fixes. This is one of the reasons; I need to
develop a standard solution. So far, I have been pre processing the messages
to prefix-suffix proper delimiters before I send it to my parser for
parsing. Segment delimiters are usually limited to '0A','0D','0D 0A' and '0A
0D'.I work in CA,USA and had a lot of interaction with Hospitals since 2-3
years. Hopefully you will be able to address this issue ?

Oh!  I thought you were talking about the minimal lower layer protocol.  Do
you mean messages in files?
