solution:
1. the dot doesn't need escaping in a character set. [ .-] should do it.
You hardly need escaping in sets as long as you choose the order of the
characters wisely.
2. I don't know if it matters, but the comment he made on ( and ) also
applies for the dots and hyphens. Can the be mixed? The regexp will
allow (200).200-0000 as a phone number too. You may need a lot more |
(ors) in there. The first thing you have to do is write down all
acceptable formats and start from there. If you ONLY accept the formats
below, I think the following regexp would do it:
^([2-9]\d\d([.-])[2-9]\d\d\2\d{4}|\([2-9]\d\d\)[ ]?[2-9]\d\d-\d{4})$
