// Example code snippet demonstrating the use of DOMDocument and DOMElement in PHP functions
// Create a new DOMDocument
$dom = new DOMDocument();
// Create a new element
$element = $dom->createElement('div');
// Set an attribute for the element
$element->setAttribute('class', 'container');
// Create a text node
$textNode = $dom->createTextNode('Hello, World!');
// Append the text node to the element
$element->appendChild($textNode);
// Append the element to the document
$dom->appendChild($element);
// Output the XML
echo $dom->saveXML();
