DomDocument->document_element

(PHP 4 >= 4.1.0)

DomDocument->document_element Returns root element node

Description

domelement DomDocument->document_element ( void )

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.

Example #1 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);

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.
