How can PHP developers ensure proper data validation and sanitization when working with XML data?

PHP developers can ensure proper data validation and sanitization when working with XML data by using functions like htmlspecialchars() to sanitize input data before inserting it into XML documents. They should also validate XML data against a schema to ensure it meets the expected structure. Additionally, developers should avoid using functions like eval() that can execute potentially harmful code embedded in XML data. 

// Example of sanitizing input data before inserting into XML document
$inputData = "<script>alert('XSS attack!');</script>";
$sanitizedData = htmlspecialchars($inputData, ENT_QUOTES, 'UTF-8');
$xml = "<data>$sanitizedData</data>";
