Re: setNodeName() ?

[Arnaud Le Hors]

There is no way to change the name of an element, along with its
namespace URI if it has one, it's an inherent part of its type and
cannot be changed once the element is created (because in some
implementations it may directly be related to a specific concrete
class). So the only way to achieve this is to actually create an element
with a new name and insert it in place of the other.
