What are some best practices for handling XML data in PHP to ensure efficient processing?

When handling XML data in PHP, it is important to use efficient methods to process the data to avoid performance issues. One best practice is to utilize PHP's SimpleXML extension, which provides a simple and intuitive way to parse and manipulate XML data. Additionally, caching XML data when possible can help reduce the processing time and improve overall performance. 

// Example of parsing XML data using SimpleXML extension
$xmlString = '<data><item>Item 1</item><item>Item 2</item></data>';
$xml = simplexml_load_string($xmlString);

foreach ($xml->item as $item) {
    echo $item . "\n";
}
