Can you please provide a complete example of how to use this in the
update command? ie... how do we select the table/field that we want to
interrogate and make the change to?
Thanks!

It sounds like you might want to look at the regexp_replace function:

UNCTIONS-POSIX-REGEXP
Be sure to use a WHERE clause on your UPDATE with the ~ operator.
