Creating XML with Namespaces (Atom)

Creating XML With Namespaces (Atom)

The FluentDOM\DOM\Document includes a namespace resolver. You can register namespaces that will be used to resolve qualified names in methods like createElement() or setAttribute(). You can even register a default namespace.

$document = new FluentDOM\DOM\Document();
$document->registerNamespace('#default', 'http://www.w3.org/2005/Atom');

$feed = $document->appendElement('feed');
$feed->appendElement('title', 'Example Feed');
$feed->appendElement('link', ['href' => 'http://example.org/']);
$feed->appendElement('updated', '2003-12-13T18:30:02Z');
$feed->appendElement('author')->appendElement('name', 'John Doe');
$feed->appendElement('id', 'urn:uuid:60a76c80-d399-11d9-b93C-0003939e0af6');

$entry = $feed->appendElement('entry');
$entry->appendElement('title', 'Atom-Powered Robots Run Amok');
$entry->appendElement('link', ['href' => 'http://example.org/2003/12/13/atom03']);
$entry->appendElement('id', 'urn:uuid:1225c695-cfb8-4ebb-aaaa-80da344efa6a');
$entry->appendElement('updated', '2003-12-13T18:30:02Z');
$entry->appendElement('summary', 'Some text.');

$document->formatOutput = TRUE;
echo $document->saveXml();

Output
