PHP : Function Reference : DOM XML Functions : DomDocument->document_element

DomDocument->document_element

Returns root element node ()
domelement DomDocument->document_element ( )

This function returns the root element node of a document.

The following example returns just the element with name CHAPTER and prints it. The other node -- the comment -- is not returned.

Example550.Retrieving root element

<?php
include("example.inc");

if (!
$dom = domxml_open_mem($xmlstr)) {
echo
"Error while parsing the document\n";
exit;
}

$root = $dom->document_element();
print_r($root);
?>

The above example will output:

domelement Object
(
[type] => 1
[tagname] => chapter
[0] => 6
[1] => 137960648
)

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);
