DomDocument->document_element — Devuelve el nodo del elemento raíz
Descripción
Esta función devuelve el nodo de elemento raíz de un documento.
El siguiente ejemplo devuelve tan solo el elemento con nombre CHAPTER y lo imprime. El otro nodo -- el comentario -- no es devuelto.
Example #1 Recuperar el elemento raíz
<?php
include("ejemplo.inc");
if (!$dom = domxml_open_mem($cadena_xml)) {
echo "Ha ocurrido un error al procesar el documento\n";
exit;
}
$raiz = $dom->document_element();
print_r($raiz);
?>
El resultado del ejemplo seria:
domelement Object ( [type] => 1 [tagname] => chapter [0] => 6 [1] => 137960648 )

The last note is incorrect. The class he is referring to is DOMDocument, not DomDocument. This page is for the PHP 4 extension. Doing "new DomDocument" would be a fatal error in PHP 5 unless you hacked the old extension into it which would be a very useless move.

The domelement returned by this will function as a domnode object for things like ->append_child.
$nodeChild = myxmldoc->create_element('child');
$nodeRoot = $this->myxmldoc->document_element();
$nodeRoot->append_child($nodeChild);

as of PHP 5 (tested with 5.1.4), remember to use documentElement instead. As in:
$dom = new DomDocument ();
$dom -> load ('file.xml');
$newEl = $dom -> createElement ('newEl');
$dom -> documentElement -> appendChild ($newEl);
