Parser Engine Versions

There are three different parser engines in Chameleon. The features available in each parser engine are summarized in the table below:

Feature	Parser Engine 3.211.244 (Deprecated)	Parser Engine 4.5	Parser Engine 5.0 (Recommended)
Parses HL7 messages?
Supports validation rules?
Can differentiate between multiple versions of each segment based on segment identities and/or location in the segment grammar?
Properly ignores segments when the Ignore segments not in grammar option is enabled? (i.e. segments are not dropped after the engine parses the first segment)
Supports unordered parsing groups?
Enhanced support for validation rules?
Improved behavior for Python field objects?
Enhanced support for present but null values?
Bypasses incorrectly inserted \n characters after \r characters in segments?

	Did you know? The 5.0 Parser Version parses messages approximately 40 percent faster than the 4.5 Parser Version.
