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

When parsing HTML content in PHP, using DOMDocument is advantageous over preg_match because DOMDocument provides a more reliable and structured way to navigate and manipulate HTML elements. DOMDocument allows for easier traversal of the HTML document tree, making it simpler to extract specific elements or attributes. Additionally, DOMDocument is better suited for handling complex HTML structures and ensures better compatibility with various HTML documents. 

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

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

// Get all the <a> tags in the HTML content
$links = $doc->getElementsByTagName('a');

// Loop through each <a> tag and extract the href attribute
foreach ($links as $link) {
    echo $link->getAttribute('href') . "\n";
}
