What are the common pitfalls when working with XML data in PHP functions?

One common pitfall when working with XML data in PHP functions is not properly handling errors that may occur during parsing or processing the XML. To avoid this issue, it is important to use try-catch blocks to catch and handle any exceptions that may be thrown. 

try {
    // Load the XML data
    $xml = simplexml_load_string($xmlData);
    
    // Process the XML data
    // Your code here
    
} catch (Exception $e) {
    // Handle any errors that occur during XML processing
    echo "Error: " . $e->getMessage();
}
