What are the potential pitfalls of incorrectly referencing XML elements in PHP when parsing data?

Incorrectly referencing XML elements in PHP when parsing data can lead to errors such as undefined index notices or incorrect data retrieval. To avoid these pitfalls, it's crucial to ensure that the XML elements are correctly referenced using the appropriate methods provided by PHP's XML parsing functions, such as SimpleXMLElement or DOMDocument. 

// Example of correctly referencing XML elements when parsing data
$xml = '<data><name>John</name><age>25</age></data>';
$xmlObj = new SimpleXMLElement($xml);

// Correctly reference XML elements
$name = (string) $xmlObj->name;
$age = (int) $xmlObj->age;

echo "Name: $name, Age: $age";
