What are the common challenges faced by PHP beginners when trying to extract specific data from HTML content using PHP functions like xpath and simplexml_import_dom?

Beginners often struggle with understanding how to navigate through the HTML structure using xpath or simplexml_import_dom functions to extract specific data. To overcome this challenge, it's important to familiarize oneself with the HTML structure and use xpath expressions effectively to target the desired elements. 

// Example code snippet to extract specific data from HTML content using xpath and simplexml_import_dom

$html = '<div>
            <h1>Title</h1>
            <p>Paragraph 1</p>
            <p>Paragraph 2</p>
        </div>';

$dom = new DOMDocument();
$dom->loadHTML($html);

$xpath = new DOMXPath($dom);
$elements = $xpath->query('//div/p');

foreach ($elements as $element) {
    echo $element->nodeValue . "\n";
}
