What are some potential pitfalls of using regular expressions to parse HTML content in PHP?

Parsing HTML content using regular expressions in PHP can be error-prone as HTML is a complex and nested structure that is not easily captured by regex patterns. It is recommended to use a dedicated HTML parser like DOMDocument or SimpleHTMLDom instead, as they are specifically designed to handle HTML parsing and manipulation. 

// Example using DOMDocument to parse HTML content
$html = '<div><p>Hello, World!</p></div>';
$dom = new DOMDocument();
$dom->loadHTML($html);

// Accessing elements using DOM methods
$paragraph = $dom->getElementsByTagName('p')[0];
echo $paragraph->nodeValue; // Output: Hello, World!
