The square brackets match a single character. Within the brackets you
must include a list of characters you want to match.
Examples:
match even characters: [02468]
match odd characters: [13579]
match one through five: [1-5]
match letters a through h: [a-h]
You could have a regular expression within the square brackets, but it
should evaluate to a nonredundant list of numbers of letters to be of
any use or make any sense. And whatever is within the brackets is
matched against a single character.
HTH,
Jonathan
