Using perl to control the characters type

Henry Chua — Wed, 13 Dec 2006 20:15:43 GMT

Hi guys,

Do you know how i can use perl scripting regular expression to control the input.

I would like the input to be 9 characters
1st character is alphabet, 2nd is digit, third alphabet follow by 6 digits. I am not sure how to control individual character.

Thanks in advance.

Best regards
Henry

if ($var =~ /^[a-zA-Z]\d[a-zA-Z]\d{6}$/) {
/* do something */
}

if you're new to re stuff, using the x modifier might help you understand it later

$var =~ m{
^ # Start of string
[a-z] # 1st A letter
\d # 2nd A digit
[a-z] # 3rd A letter
\d {6} # 4th 6 digits
$ # End of string
}xi; # x = allow space and comments (use \s to match space)
# i = ignore case

Enjoy, Have FUN! H.Merijn
