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
