Are there any potential pitfalls to be aware of when iterating through XML data in PHP?

One potential pitfall when iterating through XML data in PHP is not properly handling namespaces. If the XML document contains namespaces, you need to account for this in your code to access the elements correctly. One way to solve this issue is to use the `->children()` method to access elements within a specific namespace. 

$xml = simplexml_load_string($xmlString);

// Define namespaces
$ns = $xml->getNamespaces(true);

// Iterate through XML data
foreach ($xml->children($ns['namespace']) as $element) {
    // Access elements within the specified namespace
    // Do something with $element
}
