ElementGetElementsByTagNameNS

public final class ElementGetElementsByTagNameNS extends DOMTestCase
The method getElementsByTagNameNS returns a NodeList of all the Elements with a given local name and namespace URI in the order in which they are encountered in a preorder traversal of the Document tree. Invoke getElementsByTagNameNS on the documentElement with values for namespaceURI '*' and localName '*'. Verify if this returns a nodeList of 0 elements.
