Transformers

(FluentDOM >= 5.1)

Transformers take a DOM document and transform it into a new one.

Namespaces\Optimize

This optimizes the xmlns/xmlns:* attributes in an document. It puts the prefix definition up into the farthest ancestor node possible.

You can provide a namespace to prefix mapping. The prefixes of all matching element/attributes are changed.

$transformer = new FluentDOM\Transformer\Namespaces\Optimize(
  $document,
  [
    'http://www.w3.org/2005/Atom' => 'feed',
    'http://www.w3.org/1999/xhtml' => ''
  ]
);
$target = $transformer->getDocument();
$target->formatOutput = TRUE;
echo $target->saveXML();
