Incompatibilities with Python 3.9a6: Element.getiterator is gone #953
Description
https://docs.python.org/3.9/whatsnew/3.9.html#removed
Methods
getchildren()andgetiterator()of classesElementTreeandElementin theElementTreemodule have been removed. They were deprecated in Python 3.2. Useiter(x)orlist(x)instead ofx.getchildren()andx.iter()orlist(x.iter())instead ofx.getiterator(). Thexml.etree.cElementTreemodule has been removed, use thexml.etree.ElementTreemodule instead. Since Python 3.3 thexml.etree.cElementTreemodule has been deprecated, thexml.etree.ElementTreemodule uses a fast implementation whenever available. (Contributed by Serhiy Storchaka in bpo-36543.)
