What are best practices for accessing and displaying data from XML files using SimpleXML in PHP?

When accessing and displaying data from XML files using SimpleXML in PHP, it is important to use the appropriate methods provided by SimpleXML to navigate through the XML structure and extract the desired data. Best practices include checking for the existence of elements or attributes before accessing them, using loops to iterate over multiple elements, and properly escaping any data before displaying it to prevent XSS attacks. 

// Load the XML file
$xml = simplexml_load_file('data.xml');

// Access and display data from the XML file
foreach($xml->children() as $child) {
    echo 'Element: ' . $child->getName() . '<br>';
    echo 'Value: ' . htmlspecialchars($child) . '<br>';
}
