What are the advantages of using DOMDocument and DOMXPath in PHP for parsing HTML?

When parsing HTML in PHP, using DOMDocument and DOMXPath provides a more robust and reliable way to navigate and extract data from the HTML document compared to using regular expressions. DOMDocument allows you to load the HTML document into a structured object model, making it easier to access specific elements and attributes. DOMXPath, on the other hand, provides a powerful querying mechanism to select specific elements based on XPath expressions. 

// Create a new DOMDocument object and load the HTML content
$doc = new DOMDocument();
$doc->loadHTML($html);

// Create a new DOMXPath object to query the DOMDocument
$xpath = new DOMXPath($doc);

// Use XPath query to select specific elements
$elements = $xpath->query('//div[@class="content"]');

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