What are the potential pitfalls of working with XML files in PHP?

One potential pitfall of working with XML files in PHP is the risk of encountering parsing errors if the XML file is not well-formed or valid. To mitigate this risk, it is important to validate the XML file before attempting to parse it. This can be done using PHP's built-in SimpleXML extension, which provides functions for parsing and validating XML documents. 

$xml = file_get_contents('example.xml');

// Validate the XML file
if (simplexml_load_string($xml)) {
    // Parse the XML file
    $xmlObject = simplexml_load_string($xml);

    // Access XML data
    // Example: echo $xmlObject->elementName;
} else {
    echo 'Invalid XML file';
}
