Examples

Example #1 Creating a new element and inserting it as root

<?php

$dom 
= new DOMDocument('1.0''utf-8');

$element $dom->createElementNS('http://www.example.com/XFoo''xfoo:test''This is the root element!');

// We insert the new element as root (child of the document)
$dom->appendChild($element);

echo 
$dom->saveXML();
?>

The above example will output:

 <?xml version="1.0" encoding="utf-8"?> <xfoo:test xmlns:xfoo="http://www.example.com/XFoo">This is the root element!</xfoo:test> 

Example #2 A namespace prefix example

<?php
$doc  
= new DOMDocument('1.0''utf-8');
$doc->formatOutput true;
$root $doc->createElementNS('http://www.w3.org/2005/Atom''element');
$doc->appendChild($root);
$root->setAttributeNS('http://www.w3.org/2000/xmlns/' ,'xmlns:g''http://base.google.com/ns/1.0');
$item $doc->createElementNS('http://base.google.com/ns/1.0''g:item_type''house');
$root->appendChild($item);

echo 
$doc->saveXML(), "\n";

echo 
$item->namespaceURI"\n"// Outputs: http://base.google.com/ns/1.0
echo $item->prefix"\n";       // Outputs: g
echo $item->localName"\n";    // Outputs: item_type
?>

The above example will output:

 <?xml version="1.0" encoding="utf-8"?> <element xmlns="http://www.w3.org/2005/Atom" xmlns:g="http://base.google.com/ns/1.0"> <g:item_type>house</g:item_type> </element> http://base.google.com/ns/1.0 g item_type
