I am actually a bit shocked that no-one mentioned using
a negated character class to grab what you need. The idea
is to grab everything that is not the character
'<':
my ($title) = $chunk =~ /<title>([^<]+)/;
my @h1 = $chunk =~ /<h1>([^<]+)/g;
However, this is still not perfect. I personally think that
nothing is too simple for a parser module, especially if
that parser module is HTML::TokeParser::Simple:
use strict;
use warnings;
use Data::Dumper;
use HTML::TokeParser::Simple;
my $d = do {local $/;<DATA>};
my $p = HTML::TokeParser::Simple->new(\$d);
my %hash;
while ( my $token = $p->get_token ) {
$hash{title} = $p->get_token->return_text
if $token->is_start_tag('title');
push @{$hash{h1}}, $p->get_token->return_text
if $token->is_start_tag('h1');
}
print Dumper \%hash;
__DATA__
<html>
<head>
<title>foo</title>
</head>
<body>
<h1>one</h1>
<h1>two</h1>
<h1>three</h1>
</body>
</html>

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
