Description:

sys.rexp_match() matches a regular expression in a string. If there is a match, then the return value is the string that matched and sys_ret is set to the index into <text> of the start of the match. If there is no match, then the return is an empty string and sys_ret is set to -1. You should check sys_ret to determine if an empty return string means there was not a match.
