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

When parsing HTML in PHP, using DOMDocument is generally preferred over regex due to its ability to accurately parse and manipulate HTML documents in a structured way. DOMDocument provides a more reliable and robust solution for handling HTML content, as it follows the Document Object Model (DOM) standard. This allows for easier traversal, modification, and extraction of specific elements within the HTML document compared to using regex, which can be error-prone and difficult to maintain.

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

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

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

// Loop through the elements and extract their content
foreach ($elements as $element) {
    echo $element->nodeValue . "<br>";
}
