NodeIterator.nextNode()

method returns the next node
in the set represented by the NodeIterator
and advances the position of
the iterator within the set. The first call to nextNode()

In old browsers, as specified in old versions of the specifications, the method may
throws the INVALID_STATE_ERR
DOMException
if this method
is called after the NodeIterator.detach()
method. Recent browsers never
throw.
