What are the advantages of using DomDocument and DomXPath over regex for parsing HTML in PHP?

When parsing HTML in PHP, using DomDocument and DomXPath is preferred over regex because these classes provide a more robust and reliable way to navigate and manipulate HTML documents. DomDocument allows for easy traversal of the HTML structure, while DomXPath enables querying specific elements using XPath expressions. This approach is more maintainable and less error-prone compared to using regex, which can be complex and brittle when dealing with HTML. 

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

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

// Create a new DomXPath object
$xpath = new DomXPath($dom);

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

// Loop through selected elements and do something
foreach ($elements as $element) {
    // Do something with the element
}
