Hi all
Just for fun (really no context) i was wondering how to create regular
expressions that
will never match any string.
/^[^\w\W]/ is one of them am I right? No string can start with a character
that is neither alphanumeric nor nonalhanumeric.
But why does
/^[^.\n]/ matches .
doesn't that mean the string should begin a character that is not any
character or not a newline(nothing else should be left).
Could someone enligthen me?
Below is to code I use to check.
thanks
oznur
use strict;
use warnings;
my $string="does it match";
if ($string=~/(^[^\w\W])/){
print "matches $1\n";
}
else {
print "doesn't match \n";
}
if ($string=~/(^[^.\n])/){
print "matches $1\n";
}
else {
print "doesn't match \n";
}
