Just trying to add some clarification: this function will return boolean "false" when there is not a $name attribute :)

Cheers, Alex

It may also return DOMNameSpaceNode if you`re requesting 'xmlns:_prefix_'. So you`re unable to remove it with removeAttributeNode() which requires DOMAttr as parameter.
