TypeError: write() got an unexpected keyword argument 'short_empty_elements'

Below is a minimal working example. I have tested this with Python 3.4, Python 3.6 32 bit and Python 3.6 64 bit.

import io
from lxml import etree    
test_node = etree.fromstring('''
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://docs.oasis-open.org/ws-sx/ws-trust/200512">
  <soap:Body>
     <ns1:RequestSecurityToken/>
  </soap:Body>
</soap:Envelope>''')
output = io.BytesIO(b'<?xml version="1.0" encoding="UTF-8"?>')
test_node.getroottree().write(output,
                         encoding="UTF-8",
                         xml_declaration=None,
                         default_namespace=None,
                         method="c14n",
                         short_empty_elements=False
                         )
output.seek(0)
print(output.read())

Result:

Traceback (most recent call last):
  File "C:/not_telling/c14n.py", line 16, in <module>
    short_empty_elements=False
  File "lxml.etree.pyx", line 1869, in lxml.etree._ElementTree.write (src\lxml\lxml.etree.c:57004)
TypeError: write() got an unexpected keyword argument 'short_empty_elements'

I have just upgraded lxml version to 4.0.0. (But the same is the issue with 3.7.)

There was a similar issue on github ( https://github.com/seveas/python-hpilo/issues/49 ) but I think that is a different problem.

Any clue, what should I do?

I don't see any pytho-hpilo code in your example, could you explain why there is a python-hpilo bug here?

Wow, I have posted this issue to the wrong project, sorry. :-(

No problem! Good luck with the issue.
