What are some common pitfalls to avoid when working with external XML data in PHP?

One common pitfall when working with external XML data in PHP is not properly handling errors or exceptions that may occur during the parsing or processing of the XML. To avoid this, always wrap your XML parsing code in a try-catch block and handle any potential errors gracefully. 

try {
    $xml = simplexml_load_file('external_data.xml');
    // Process the XML data here
} catch (Exception $e) {
    echo 'Error loading XML: ' . $e->getMessage();
}
