getElementsByTagNameNS: namespaceURI,
localName(2)
Like the getElementsByTagName
method, returns a
list of Element
nodes
(descendants of the Element
node on which the method is called) that match the criteria given
in the namespaceURI
and
localName
parameters. The
resulting list contains all elements matching the namespace URI
and local name restrictions, as they would be encountered in a
preorder traversal of the document tree.
