What are the benefits of using a DOM parser over regular expressions for parsing HTML in PHP?

Using a DOM parser over regular expressions for parsing HTML in PHP is beneficial because it provides a more robust and reliable way to navigate and manipulate the HTML structure. DOM parsers understand the structure of HTML documents and allow you to easily access specific elements, attributes, and text content. Regular expressions, on the other hand, can be error-prone and difficult to maintain when dealing with complex HTML. 

// Using DOM parser to parse HTML in PHP
$html = '<div><p>Hello, World!</p></div>';
$dom = new DOMDocument();
$dom->loadHTML($html);

// Get the text content of the <p> element
$pElement = $dom->getElementsByTagName('p')->item(0);
$textContent = $pElement->textContent;

echo $textContent; // Output: Hello, World!
