In what situations should the use of PHP's built-in XML functions be preferred over manually manipulating data structures, as seen in the code?

When dealing with XML data, using PHP's built-in XML functions is preferred over manually manipulating data structures because it provides a more robust and efficient way to parse, manipulate, and generate XML. These functions handle common XML tasks such as parsing XML documents, creating XML elements, and transforming XML data. By utilizing these built-in functions, you can avoid potential errors that may arise from manual manipulation and ensure compatibility with various XML standards. 

// Example of using PHP's built-in XML functions to parse an XML document
$xmlString = '<root><item>Value</item></root>';
$xml = simplexml_load_string($xmlString);

// Accessing the XML data
$itemValue = $xml->item;

echo $itemValue; // Output: Value
