I designed HL7v2 and v3 (xml based) parsers in Mirth. It was horrible, but boy did I learn a ton. Subtle bugs could lead to scary outcomes like drug doses being way off. Seeing the string “PID” still causes nightmares.

Pelvis Inflammatory Disease as a data format - a perfect description for HL7.

Mirth is so useful for debugging, though.
