Answer 1

You just need to create new parent elements and then append the child.

$bookstore = $doc->createElement('Bookstore');
$book = $doc->createElement("Book");

/* your code */

/* append name and url to $book */
$book->appendChild($textareaNode);
$book->appendChild($textareaNode1); 
$bookstore->appendChild($book);
$doc->appendChild($bookstore);

$doc->save("d.xml");
