How can using DOM manipulation in PHP be more advantageous than regular expressions when parsing HTML content?

When parsing HTML content, using DOM manipulation in PHP can be more advantageous than regular expressions because DOM manipulation allows for more structured and reliable parsing of HTML elements. Regular expressions can be error-prone and difficult to maintain when dealing with complex HTML structures. DOM manipulation provides a more intuitive way to traverse the HTML document, access specific elements, and extract the desired data. 

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

// Load the HTML content into the DOMDocument
$doc->loadHTML($html_content);

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

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