XSLT might be a nice and clean way to do this. I.e., your application would 
convert HL7 to XML, then run that through a simple XSLT transformation that 
would elide the fields you didn't want, then convert the XML result back into HL7.

Then your XSLT file becomes the "configuration" of the filter.
