It seem that the domDocument 'create_element' method don't work anymore in php 5.2.6.
We have to use the DOM 'createElement' instead.

When creating empty nodes like xhtml:link, the output misses the closing slash. This is what I got:

<link ...>

The first example on this page is also a bit verbose. Since the DomElement class inherits/extends the DomNode class, one does not, in fact, have to get another reference to the first node. The create_element method has already given you that reference. (Also, the last line passes a string to the append_child method, instead of a DomNode object) Simplified:

<?
$new_element = $dom->create_element("new_element");
$new_element->append_child($another_element);
$oldTag->append_child($new_element);
?>

The example done by Nico Almhoedi has a small error.

Since append_child only accepts DomElement (which is an object), it should've been:

$new_element = DomDocument->create_element("new_el");
$new_node = $existent_node->append_child($new_element);

It's easier possible since DomNode->append_child($new_element) returns the new child as an object, so you can refer to it immediately.

To append a child to the node $existent_node:

$new_element = DomDocument->create_element("new_el");
$new_node = $existent_node->append_child("new_el");

see Manual DomNode->append_child()

Its important to remember, when adding a created element to an existing node using append_child(), that if you want to then add another element to that node you have to go back and set up a DOMNode instance using DOMDocument_get_elements_by_tagname or similar before you can append another node onto it.

eg

<?
$new_element = $dom->create_element("new_element");
$oldTag->append_child($new_element);
//Go back and set up new element as DOMNode
$new_elementArray = $dom->get_elements_by_tagname("new_element");
$new_elementTag = $new_elementArray[0];//(if theres more than one use a for loop)

$new_elementTag->append_child("another_new_element");
?>
