We present a parser to evaluate expressions and boolean selections that is applied on CMS event data for event filtering and analysis purposes. The parser is based on boost spirit grammar definition, and uses Reflex dictionary for class introspections. The parser allows a natural definition of expressions and cuts in users configuration, and provides good run-time performances compared to other existing parsers.
