I have a function to replace the content of an ElementTree Element by
that of another one which works using Python 2 but not with Python 3.
I get an assertion error. The function is as follows:
def replace_element(elem, replacement):
'''replace the content of an ElementTree Element by that of
another
one.
'''
elem.clear()
elem.text = replacement.text
elem.tail = replacement.tail
elem.tag = replacement.tag
elem.attrib = replacement.attrib
elem[:] = replacement[:]
The last line is problematic. For example, if I do the following
program with Python2.5
###
from xml.etree import ElementTree as et
a = et.Element('a')
b = et.SubElement(a, 'b')
c = et.Element('c')
a[:] = c[:]
###
nothing of note happens - however, doing the same with Python 3.1, I
get the following traceback:
Traceback (most recent call last):
File "test.py", line 7, in <module>
a[:] = c[:]
File "/usr/local/py3.1/lib/python3.1/xml/etree/ElementTree.py", line
210, in __setitem__
assert iselement(element)
AssertionError
======
I would gladly welcome any suggestion for writing a replace_element()
function that works with Python 3.1
