ABSTRACT:
A system for processing regular expressions containing one or more sub-expressions. Information regarding one or more regular expressions, each containing one or more sub-expressions, is stored. Data is compared to the stored information regarding expressions in only a single pass through the data. From the comparison, for any stored expression, the location within the data of the beginning and end of each sub-expression, and the end of the regular expression, are determined. From such determination, the presence within the data of any one or more stored regular expressions containing one or more sub-expressions is identified.
