The FIX <-> FIXML Converter is a utility library included in the OnixS FIX Engine .NET and JAVA distributions with C# and JAVA sample reference implementations.
It is useful where a conversion is required between the FIX tag/value and FIXML XML formats based equivalent data models.
Use-cases include internal integration requirements, and venue specific contexts where an Exchange provides trade feeds in FIXML format. A common example of this is the CME Straight Through Processing (CME STP) FIXML 5.0 SP2 post-trade messages containing NYMEX, COMEX, DME, CBOT via CMD, and CME cleared trade information.
