regular expression
A pattern of literal and special characters that describes a set of character strings. The use of regular expressions in text searches locates one or more occurrences of the character strings represented by the expression. A search using a regular expression is more powerful than a search for a simple character string, since the regular expression represents a greater (potentially infinite) number of character strings and searches for them in parallel. In ABAP, regular expressions can be used in the statements FIND
and REPLACE , as arguments in certain predefined functions , and in the classes CL_ABAP_REGEX and CL_ABAP_MATCHER .
