Character Functions
Regex
The first argument is the source string that Regex searches for a match to the pattern. The second argument
is the pattern, in the form of a regular expression. The Formula Editor prompts you for these two required
arguments.
Tip: For more information about using regular expressions, search the Internet for regular expression tutorial.
By default, Regex performs a case-sensitive search and returns the parts of the source string that match the
pattern that you specified (or returns MISSING if the match fails). There are two optional arguments that
you can add. You can type a third argument—the format—that specifies the string to return. If you choose,
you can use regular expressions to specify replacement text in the returned string. If you specify the third
argument, you can also specify IGNORECASE so that Regex ignores capitalization when searching the
source string for a match.
Table B.1 Regex Examples
Sample Regex function
Regex( "@ q3 #", "([a-z])([0-9])" )
Regex( "@ Q3 #", "([a-z])([0-9])",
"\0",IGNORECASE)
Regex( "@ Q3 #", "([a-z])([0-9])",
"\2\1",IGNORECASE)
String that is returned
q3
The function is case sensitive, so q3 matches but Q3
would not.
Q3
Although \0 is the default argument, it is required in
this example so that IGNORECASE can be
specified.
3Q
