Cloning a tree 2003-01-13 - By Joseph Kesselman
See documentation for the DOM Level 2 Node.cloneNode() method. But note
that this is not guaranteed to work on Document nodes; in some
implementations, you may have to create a new Document, and then use the
DOM Level 2 importNode() method to copy the children of the old Document
into the new one... so see the docs for that too. (See also
http://www.w3.org/DOM/faq.html#ownerdoc for discussion of why importNode
is different from cloneNode.)
If you're writing DOM Level 1 code, then yes, you must provide your own
code to walk and copy the tree.
