What are the best practices for handling HTML parsing in PHP, considering performance and error handling?

When parsing HTML in PHP, it is important to use a reliable library like DOMDocument for better performance and error handling. This library allows you to easily navigate and manipulate HTML documents while handling errors gracefully. 

// Create a new DOMDocument object
$dom = new DOMDocument();

// Load HTML content from a file or string
$html = "<html><body><p>Hello, World!</p></body></html>";
$dom->loadHTML($html);

// Use DOMXPath to query elements in the HTML document
$xpath = new DOMXPath($dom);
$paragraphs = $xpath->query("//p");

// Loop through the queried elements and output their content
foreach ($paragraphs as $paragraph) {
    echo $paragraph->nodeValue;
}
