What are the advantages of using DOMDocument over string manipulation for parsing HTML in PHP?

When parsing HTML in PHP, using DOMDocument provides a more reliable and robust way to navigate and manipulate the HTML structure compared to string manipulation. DOMDocument allows you to easily traverse the HTML tree, access specific elements, modify content, and extract data without the risk of breaking the structure. This approach is more maintainable, scalable, and less error-prone than manually manipulating HTML strings. 

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

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

// Get specific elements by tag name, class, id, etc.
$elements = $doc->getElementsByTagName('a');

// Iterate over the elements and extract data
foreach ($elements as $element) {
    echo $element->getAttribute('href') . "\n";
}
