And also a bit error prone (unless you are sure the replaced string really
only occurs where you want to replace it). You can try this:

   root = etree.parse(...).getroot()
   new_root = etree.Element(root.tag, root.attrib)
   new_root[:] = root[:]

Note, however, that this will not copy root-level PIs or internal DTD subsets.
But you can copy PIs and comments by hand.
