I want to extract the textual parts of HTML pages (i.e. the texts that a browser normally shows). I am using the following script, however with some pages it prints out code too. The script and the url can reproduce the issue. Any idea?

use strict;
use warnings;
use LWP::Simple;
use LWP::UserAgent;
use HTML::TokeParser::Simple;

my $ua = LWP::UserAgent->new( );
my $text = do_GET_TXT("http://www.spacex.com/webcast");
print $text;

sub do_GET_TXT {
    my ($url)=@_;
    print "Downloading and reading HTML $url...\n";
    my $response = $ua->get($url);
    if ($response->is_error) {
        $response->code;
    }
    else{
        my $HTML = $response->decoded_content();
        my @text;
        require HTML::TokeParser::Simple;
        my $p = HTML::TokeParser::Simple->new(\$HTML);
        while ( my $token = $p->get_token ) {
            next unless $token->is_text;
            my $out = $token->as_is;
            $out =~ s/^\s+/\n/;
            push (@text, $out);
        }
        my $text = join("", @text);
                #some heuristics
        $text =~  s/\n+/\n/g; 
        $text =~  s/\n(\d+\.)\n/$1\t/g; 
        $text =~  s/(\(\d+\))\n/$1\t/g; 
        $text =~  s/([a-z]\))\n/$1\t/g;  
        return $text;
    }
}

I obtain more or less the same using Mojo::DOM with the following:

        
my $dom = Mojo::DOM->new($HTML);
my $text = $dom->all_text();

A bit better gets with the following (with reduces the parsing to the body, however snippets of javascript are still to be seen...

my $dom = Mojo::DOM->new($HTML);
my $text = $dom->at('body')->all_text();
