What are the potential reasons for a PHP script outputting an empty XML document?

The potential reasons for a PHP script outputting an empty XML document could be errors in the XML generation process, such as missing data or incorrect formatting. To solve this issue, ensure that the XML structure is properly defined and that the data is correctly added to the document. 

<?php
// Create a new XML document
$xml = new DOMDocument();
$xml->formatOutput = true;

// Create the root element
$root = $xml->createElement("root");
$xml->appendChild($root);

// Add data to the XML document
$data = "Hello, World!";
$element = $xml->createElement("data", $data);
$root->appendChild($element);

// Output the XML document
echo $xml->saveXML();
?>
