How can DOMDocument and DOMXPath be utilized to manipulate HTML output for PDF conversion in PHP?

By using these two classes, you can easily extract, modify, and rearrange the HTML content before converting it to PDF. 

// Load the HTML content into a DOMDocument
$dom = new DOMDocument();
$dom->loadHTML($html_content);

// Use DOMXPath to query specific elements in the HTML document
$xpath = new DOMXPath($dom);
$elements = $xpath->query('//div[@class="content"]');

// Manipulate the content of the selected elements
foreach ($elements as $element) {
    $element->nodeValue = 'New content here';
}
