What are the advantages of using DOMDocument over regular expressions for parsing HTML in PHP?

When parsing HTML in PHP, using DOMDocument is preferred over regular expressions because DOMDocument provides a more reliable and robust way to navigate and manipulate HTML documents. Regular expressions can be error-prone and difficult to maintain when dealing with complex HTML structures. DOMDocument, on the other hand, allows for easy traversal of the HTML document tree, making it easier to extract specific elements or attributes. 

// Create a new DOMDocument object
$dom = new DOMDocument();

// Load the HTML content from a file or string
$dom->loadHTML($html);

// Get specific elements from the HTML document
$elements = $dom->getElementsByTagName('div');

// Loop through the elements and extract data
foreach ($elements as $element) {
    echo $element->nodeValue;
}
