What are the potential drawbacks of using preg_match for extracting content from HTML code in PHP?

Using preg_match for extracting content from HTML code in PHP can be error-prone and difficult to maintain, especially when dealing with complex HTML structures. It is recommended to use a dedicated HTML parsing library like DOMDocument or SimpleHTMLDom instead, as they provide more robust and reliable methods for extracting content from HTML. 

// Using DOMDocument to extract content from HTML code
$html = '<div><p>Hello, World!</p></div>';
$dom = new DOMDocument();
$dom->loadHTML($html);

// Extracting content using DOMDocument
$paragraphs = $dom->getElementsByTagName('p');
foreach ($paragraphs as $paragraph) {
    echo $paragraph->nodeValue; // Output: Hello, World!
}
