What are some alternative methods in PHP, besides regular expressions, for extracting specific content from HTML elements?

When extracting specific content from HTML elements in PHP, we can use the DOMDocument class to parse and manipulate HTML documents. By using DOMDocument, we can easily navigate through the HTML structure and extract the desired content without relying on regular expressions, which can be error-prone when dealing with complex HTML. 

// Create a new DOMDocument
$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('div');

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