move command acts exactly like
copy, except that it
removes the source nodes after a
successful copy. Remember that the moved nodes are
actually different nodes from the
original ones (which may not be obvious when moving
nodes within a single document into locations that do
not require type conversion). So, after the move, the
original nodes don't belong to any document
and are automatically destroyed unless some
variable still contains to them.
This command returns a node-list consisting of nodes it created on the target locations.
See copy for more details on how the copies of the moved nodes are created.
