    You probably do not want to see
    m{^(?: ntv\.com/very-own/ | ntv\.com/business/ | ntv\.com\.wid-prl\.com/very-own/ | ltv\.com/very-own/ )$}x
    as the answers. Tell us more: What conditions should it not match? What are you trying to achieve?

    print "$_: ", m[[nl]tv\.(?:com\.wid-prl\.)?com/(?:business|very-own)/] + ? 'matches' : 'nomatch' for qw[ ];; matches matches matches matches

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.
      good code, but I would add ^ and $

    Using Regexp::Assemble

    use strict; use warnings; use Regexp::Assemble; my $re=Regexp::Assemble->new(); $re->add('ntv\.com/very-own/'); $re->add('ntv\.com/business/'); $re->add('ntv\'); $re->add('ltv\.com/very-own/'); print $re->re."\n";
