Could anyone explain me some basis reg. exp? I need it for some validation routiones! (See Links Cust. forum)

For example will /^[a-zA-Z_\-.\s]+$/ only allow a-z A-Z _- and spaces?

...and will /^[0-9]$/ will allow everything except 0-9?

Many thanks in advance!

Yep. That's what it appears.

No. It will allow one digit and one digit only.

(I just played around with this to check it out. That's the only way I can figure them out.)

Run, don't walk, do not pass go -- out to your local super bookstore and pick up a copy of "Mastering Regular Expressions" by Oreilly. It's in the same series as everything else about perl, I can't see my copy in this mess so I can't tell you what color it is -- but I think it's blue.

It's quickly becoming the bible on regex's.

Thanks, i ordered it today at amazon.co.uk.

But maybe someone kan help me find a nice reg. exp for a field with streetname and number.

Like: "Streetname 1"
Streetname must contain at leist 3 char, at least 1 space, and at least 1 number. dots allowed


/\w{3,}\.\s+\d+/ is not correct, because "Bond St. 3" and "Bond St 3" is false.
