What are the potential pitfalls when using regular expressions to extract text from HTML files in PHP?

One potential pitfall when using regular expressions to extract text from HTML files in PHP is that HTML is a complex language and can have nested tags, which can make it difficult to accurately match the desired text. To solve this issue, it is recommended to use a more robust HTML parsing library like DOMDocument or SimpleHTMLDom instead of relying solely on regular expressions. 

// Using DOMDocument to extract text from HTML files
$html = file_get_contents('example.html');
$dom = new DOMDocument();
$dom->loadHTML($html);

// Get all the text content from the HTML file
$text = $dom->textContent;

echo $text;
