[New-bugs-announce] [issue35013] Add more type checks for children of xml.etree.ElementTree.Element

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

Currently some methods for xml.etree.ElementTree.Element check the type subelements: append(), extend(), insert(). But there are other ways to add non-Element children: __setitem__(), __setstate__(), __deepcopy__(). This could cause crashes later in the C code and required to add numerous type checks for iterating and searching. Since the intention was to prevent adding non-Element children, it is better to check the type every time when add new children.
