What is the potential issue with using regular expressions to parse HTML in PHP?

Using regular expressions to parse HTML in PHP can be problematic because HTML is a complex language with nested structures, making it difficult to accurately parse using regular expressions alone. Instead, it is recommended to use a dedicated HTML parsing library like DOMDocument or SimpleHTMLDOM to ensure accurate and reliable parsing of HTML content. 

// Create a DOMDocument object
$doc = new DOMDocument();
// Load the HTML content from a file or string
$doc->loadHTML($html_content);
// Use DOMXPath to navigate and extract specific elements
$xpath = new DOMXPath($doc);
$elements = $xpath->query('//div[@class="example"]');
// Loop through the elements and do something with them
foreach ($elements as $element) {
    echo $element->nodeValue;
}
