Compiles the source regular expression in pattern into an executable version and returns a handle for subsequent calls to rexMatch andrexClose. flags defines the attributes of the compilation process: | Flag | Description | | rexOpenExtended | Support extended regular expressions. | | rexOpenIgnorecase | Ignore case in match. | | rexOpenNewline | Treat new-line character as a special end-of-line character; it then establishes the line boundaries matched by the ^ and $ patterns, and can only be matched within a string explicitly using \n. (If you omit this flag, the new-line character is treated like any other character.) | | rexOpenNosubreps | Ignore the number of subexpressions specified in pattern. When you compare a string to the compiled pattern (using rexMatch), the string must match the entire pattern. rexMatch then returns a value that indicates only if a match was found; it does not indicate at what point in the string the match begins, or what the matching string is. | |
