What potential pitfalls should beginners be aware of when working with PHP DOM XML?

Beginners working with PHP DOM XML should be aware of potential pitfalls such as not properly handling errors or exceptions, not sanitizing input data before using it in XML manipulation, and not understanding the structure and syntax of XML documents. To avoid these issues, beginners should always use error handling techniques, validate and sanitize input data, and familiarize themselves with XML standards and best practices. 

// Example of error handling with PHP DOM XML
libxml_use_internal_errors(true);

$dom = new DOMDocument();
$dom->loadXML($xmlString);

$errors = libxml_get_errors();

if (!empty($errors)) {
    foreach ($errors as $error) {
        // Handle errors here
    }
}

libxml_clear_errors();
libxml_use_internal_errors(false);
