Re: regular expression inverse match NOT match?

in reply to regular expression inverse match NOT match?

There are two ways to do this. The first is to use an ordinary match and then negate the result:

if (!($string =~ /keyword/)) { print "match failed"; }

or:

unless ($string =~ /keyword/) { print "match failed"; }

The second is to use the negated binding operator !~:

if ($string !~ /keyword/) { print "match failed"; }

See perlop#Binding-Operators.

Hope that helps,
