The Node.lookupPrefix()
method returns a DOMString
containing the prefix for a given namespace URI, if present, and null
if not. When multiple prefixes are possible, the result is implementation-dependent.
Due to bug 312019, this method does not work with dynamically assigned namespaces, that is, those set with the Node.prefix
property.
