    摘要: Disclosed is a method and apparatus for matching regular expressions. A buffer of symbols giving a number of the last occurrence positions of each symbol is maintained. When two constants match on either side of a regular expression operator, the buffer of symbols is queried to determine if a member of the complement of the regular expression operator occurred between the two constants. If so, then the operator was not satisfied. If not, then the operator was satisfied.
