What potential issues can arise when generating XML files using PHP functions like Add_NewDocElement?

One potential issue that can arise when generating XML files using PHP functions like Add_NewDocElement is the incorrect formatting of the XML structure, leading to invalid XML files. To solve this issue, it is important to ensure that the elements are added in the correct order and properly nested within the XML document. 

// Create a new XML document
$doc = new DOMDocument();

// Create the root element
$root = $doc->createElement('root');
$doc->appendChild($root);

// Create a new element and add it to the root element
$newElement = $doc->createElement('newElement', 'value');
$root->appendChild($newElement);

// Output the XML document as a string
echo $doc->saveXML();
