[Solved] What does this HTML::Parser() code do in Perl? [closed]

by


From the documentation:

$p = HTML::Parser->new(api_version => 3,
                       text_h => [ sub {...}, "dtext" ]);

This creates a new parser object with a text event handler subroutine that receives the original text with general entities decoded.

Edit: 

use HTML::Parser;
use LWP::Simple;
my $html = get "http://perltraining.stonehenge.com";
HTML::Parser->new(text_h => [\my @accum, "text"])->parse($html);
print map $_->[0], @accum;

Another

#!/usr/bin/perl -w
use strict;
use HTML::Parser;
my $text;
my $p = HTML::Parser->new(text_h => [ sub {$text .= shift}, 
                                     'dtext']);
$p->parse_file('test.html');
print $text;

Which, when used on a file like this:

<html>
<head>
<title>Test</title>
</head>
<body>
<h1>Test Stuff</h1>
<p>This is a test</p>
<ul>
<li>this</li>
<li>is a</li>
<li>list</li>
</ul>
</body>
</html>

produces the following output:

Test


Test Stuff
This is a test

this
is a
list

Does that help?
