What are some potential benefits of using PHP's DOMDocument over external libraries like SimpleHTMLDom?

Using PHP's DOMDocument over external libraries like SimpleHTMLDom can provide better performance, as DOMDocument is a built-in PHP extension specifically designed for parsing and manipulating HTML/XML documents. Additionally, DOMDocument is more reliable and stable as it is maintained and updated along with PHP itself. It also offers a more standardized and object-oriented approach to working with HTML/XML documents, making it easier to understand and maintain code.

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

// Load HTML content from a file
$dom->loadHTMLFile('example.html');

// Get elements by tag name
$elements = $dom->getElementsByTagName('a');

// Loop through elements and output their href attribute
foreach ($elements as $element) {
    echo $element->getAttribute('href') . "<br>";
}
