How can PHP functions like simple XML or DOM be used to extract and modify specific elements within XML data?

To extract and modify specific elements within XML data using PHP functions like SimpleXML or DOM, you can first load the XML data into a SimpleXMLElement object or a DOMDocument object.

// Load the XML data into a SimpleXMLElement object
$xml = simplexml_load_string($xmlData);

// Find and modify a specific element within the XML data

$element->nodeValue = 'new value';
