NIST The "getElementsByTagNameNS(namespaceURI,localName)" method returns a NodeList of all descendant Elements with a given local name and namespace URI in the order in which they are encountered in a preorder traversal of this Element tree. Create a NodeList of all the descendant elements using the string "http://www.nist.gov" as the namespaceURI and "address" as the localName. The method should return a NodeList whose length is "3".
