This code takes an html file with the results of a Google search and extracts the links to files of a specified type to a text file. I have found having such links in a text file useful for automating the download of the files of a specified type, say pdf files for example. 
use strict;
use LWP::Simple;
use HTML::SimpleLinkExtor;

#usage googlestrip file:///C:/googlesearchresult.htm > urllist.txt
my $url = shift;
my $filetype = "pdf";
my $filetypelen = length($filetype);
my $offset = -$filetypelen;

my $fileget = getstore($url,"tempfile.html");

my $extor = HTML::SimpleLinkExtor->new();
$extor->parse_file("tempfile.html");

my @a_hrefs = $extor->a;

my @pdflist;

for my $element (@a_hrefs) { 

    my $suffix = substr($element,$offset,$filetypelen);

      if ($suffix =~ m/$filetype/)  {
        push @pdflist, $element;       
  
    }
    }
            for my $url (@pdflist) {
            next if ($url =~ m/\/s.*pdf/);
                print $url;
                       print "\n";
                }
unlink "tempfile.html" or die "can't unlink tempfile.html: $!";

Updated to eliminate unnecessary list per blazar's suggestion...also added code to delete tempfile after the code is done with it...
