[HAPI-devel] Problems with PipeParser

[William T H. <han...@mc...>]

Hi all,
I'm having newbie problems getting PipeParser to behave the way I think it 
should.  If I build up a basic ORU_R01 message (code that does the work is 
down below), and ask PipeParser to write it out, I get the following 
output. Note that all the lines are the same length - it seems like it's 
not flushing a string buffer between segments.  The same message works 
fine written out through the XML parser (which, unfortunately, doesn't 
help me much). Any ideas? Am I doing something wrong here??
Thanks all
-Bill Hansley

PS - Thanks, Bryan, for coordinating such a great and useful 
product/project!!
