Just in case this hasn't occurred to you, there are other things in HTML which have a src attribute.



Nobody says perl looks like line-noise any more

    Indeed and the $extor->src method returns them all. Fortunately there is another method $extor->img that returns the src attribute of the img links only.
    use strict; use warnings; use HTML::SimpleLinkExtor; my $extor = HTML::SimpleLinkExtor->new(); my $url = 'http://www.perlmonks.org'; $extor->parse_url($url); foreach my $src ( $extor->img ) { print "$src\n"; }
    Output:

    A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
