Suppose we are looking for a numeric digit then the regular expression we would search for is 0 9 The brackets indicate that the character being compared should match any one of the characters enclosed within the bracket The dash between O and 9 indicates that it is a range from O to 9 Therefore this regular expression will match any character between O and 9 that is any digit If we want to search for a special character literally we must use a backslash before the special character For example the single character regular expression matches a single asterisk In the table below the special characters are briefly described A regular expression search is case sensitive u center ANTARIS Edition User s Guide Menu Structure GPS SW 02001 1 Page 18 your position s our focus The caret 4 immediately following the left bracket has a different meaning It is used to exclude the remaining characters within brackets from matching the target string The expression A0 9 indicates that the target character should not be a digit The dollar sign will match the end of the string The expression abc will match the sub string abc only if it is at the end of the string The alternation or logic OR character allows either expression on its side to match the target string The expression alb will match a as well as b The dot will match any character The asterisk indicates that the char
