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

One common pitfall when working with XML data in PHP is not properly handling errors that may occur during parsing or manipulation of the XML. To avoid this, it is important to use try-catch blocks to catch any exceptions that may be thrown. Additionally, it is crucial to validate the XML data before attempting to parse or manipulate it to ensure it is well-formed and valid. 

try {
    $xml = simplexml_load_string($xmlString);
    if ($xml === false) {
        throw new Exception('Invalid XML data');
    }
    
    // Continue processing the XML data
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
