How can PHP developers ensure the security and integrity of XML data received through URL parameters?

PHP developers can ensure the security and integrity of XML data received through URL parameters by validating and sanitizing the input data before processing it. They can use functions like htmlspecialchars() to prevent XSS attacks and XML-specific functions like simplexml_load_string() to parse and validate the XML data. 

// Validate and sanitize XML data received through URL parameters
$xmlData = isset($_GET['xml_data']) ? $_GET['xml_data'] : '';
$cleanXmlData = htmlspecialchars($xmlData);

// Parse and validate the XML data
$xml = simplexml_load_string($cleanXmlData);
if ($xml === false) {
    // Handle invalid XML data
    die('Invalid XML data provided');
}

// Process the XML data
// ...
