in reply to Extracting full links from HTML

Here is code that looks for a link to an HTML page from the command line and generates links to each image found in the HTML page. I just took wfsp's code and swapped out his hardcoded links. Update: Also changed the code so that the full URL of each image prints. I figure that would be handy to allow for downloading any or all of the images if so desired.
use strict; use LWP::Simple; use HTML::TokeParser::Simple; #usage imglinker my $url = shift; my $content = get ($url); my $p = HTML::TokeParser::Simple->new(\$content); my $in_anchor; while (my $t = $p->get_token){ if ($t->is_start_tag('a')){ $in_anchor++; next; } if ($t->is_start_tag('img') and $in_anchor){ my $src = $t->get_attr('src'); print $url."/"."$src\n"; $in_anchor = 0; } }
