What potential pitfalls should be considered when using simplexml to parse XML data from Imageshack API in PHP?

One potential pitfall when using SimpleXML to parse XML data from the Imageshack API in PHP is that the XML structure may not always be consistent, leading to errors when trying to access specific elements. To handle this, it is important to check if the elements exist before trying to access them to avoid any undefined index errors. 

$xml = simplexml_load_string($xmlString);

// Check if the element exists before accessing it
if(isset($xml->elementName)) {
    $elementValue = $xml->elementName;
    // Use the element value as needed
} else {
    // Handle the case where the element does not exist
}
