    You could throw it at tidy (see the docs) and see if it can fix the errors. A lot better than trying to do the "right thing" on your own with regex.

    $html = <<<EOT
<html>
<head></head>
<body>
<div>
<h1>-----> hello! ----< </h1>
</div>
</body>
EOT;

$config = array ( 
  'clean'                       => true, 
  'drop-proprietary-attributes' => true, 
  'output-xhtml'                => false, 
  'show-body-only'              => false, 
  'wrap'                        => '0'
); 

$tidy = new tidy();
$tidy->parseString($html, $config, 'utf8');
$tidy->cleanRepair();

echo tidy_get_output($tidy);

    It might be that you must enable tidy first in your PHP environment.
