HTML::HeadParser to print the title

Dan Jacobson · Jul 6, 2003

/usr/share/doc/libhtml-parser-perl/examples/htitle will print out the
title of an HTML document. How do I use the lighter weight
HTML::HeadParser to do the same? I want to rewrite examples/htitle but
just don't get it.

P.S. wouldn't the example be better if it used the more efficient
tool for that job, HTML::HeadParser?

We do not have access to your filesystem, so we don't know what
"example" it is that you are talking about.

But that's OK. We don't need to see the example to answer your question.

title of an HTML document. How do I use the lighter weight

By copying the first 4 lines of code displayed when you typed:

perldoc HTML::HeadParser

and modifying them for your situation.

So what do you need us for?

--------------------------------
#!/usr/bin/perl
use strict;
use warnings;

my $text = '
<html>

<head>
<title>Perl.org</title>
<base href="http://www.perl.org/index.shtml">
<link rel="shortcut icon" href="favicon.ico">
</head>

<body bgcolor="#FFFFFF">
<p>this is the body of the document</p>
</body>

</html>
';

# code from the module's documentation

require HTML::HeadParser;
my $p = HTML::HeadParser->new;
$p->parse($text) and print "not finished";

print $p->header('Title'), "\n"; # to access <title>....</title>

The 'htitle' example script is actually more efficient than
HTML::HeadParser if there is a <title> tag in the document. It has
much less fat than HTML::HeadParser, but HTML::HeadParser is able to
abort the parsing much earlier on title-less documents.
