Try using these metacharacters when testing for types:
\d digits (0-9)
\s whitespace (' ',\t,etc.)
\w 'word' characters (a-zA-Z_,etc.)

Subject: Finding numbers ONLY in a variable
hi again all,
Sorry to keep approaching you with my regex problems, but I really
havn't had time to read up on them yet.
If I have a variable...
$var = "dfasdf";
Is it possible to get a regex to say ... "hang on I only want numerals
in my variable. I am now going to print an error :)"
if ( $var =! Digits ) {
print "You entered letters of the alphabet please try again :)";
else {
print "U entered only digits... WELL DONE!";
}
Thx,
Dan
