Hi,

I am trying to clone a Node but with certain attribute filtered out
(e.g. skip 'class' attribute, but clone everything else).

I have looked at the implementation of CloneNode() method  which
calls :CloneNodeImpl().
http://mxr.mozilla.org/mozilla1.9.1/source/content/base/src/nsNodeUtils.cpp#417

I don't know if there is a way to customize the CloneNode() for my
purpose?

Thank you for any pointers/suggestions?
