var objXMLDOMNode = oXMLDOMNamedNodeMap.removeQualifiedItem(baseName,
namespaceURI);
Parameters
baseName
The string specifying the base name of the attribute, without namespace qualification.
namespaceURI
The string specifying the namespace prefix that qualifies the attribute name.
Return Value
An object. Returns the attribute node removed, or Null if no node was removed.
