    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());

    ?>
