This method can be used to remove a namespace declaration from an element, even though the declaration is not considered an attribute by the DOM.  The prefix will be removed from any element or attribute using it.



<?php



$dom = DOMDocument::loadXML('<foo:root xmlns:foo="http:bar"/>');

$element = $dom->childNodes->item(0);



// prints '0':

echo (int) $element->hasAttributeNS('http:bar', 'foo');



$element->removeAttributeNS('http:bar', 'foo');



/* prints '<?xml version="1.0"?> <root/>': */

print htmlentities($dom->saveXML());



?>
