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()); ?>
