What alternative methods can be used to extract specific data from HTML content in PHP?

When extracting specific data from HTML content in PHP, one alternative method is to use regular expressions. Regular expressions allow you to define patterns that can match specific content within the HTML. By using regular expressions, you can extract the desired data efficiently and effectively. 

$html = file_get_contents('http://example.com/page.html');
$pattern = '/<div class="content">(.*?)<\/div>/s';
preg_match($pattern, $html, $matches);
$data = $matches[1];
echo $data;
