I just discovered lxml.objectify which seems nice and easy for reading/writing simple XML files.

Firstly, is it a good idea to use lxml.objectify? For instance is it mature and still developed and likely to be available in the future?

Secondly, how do I prevent objectify from addding markup like xmlns:py="http://codespeak.net/lxml/objectify/pytype" py:pytype="str" in the output below ?.

Input : config.xml

<?xml version="1.0" encoding="utf-8"?>
<Test>
  <MyElement1>sdfsdfdsfd</MyElement1>
</Test>

Code

from lxml import etree, objectify

with open('config.xml') as f:
    xml = f.read()
root = objectify.fromstring(xml)

root.Information = 'maybe'

print etree.tostring(root, pretty_print=True)

Output

<Test>
  <MyElement1>sdfsdfdsfd</MyElement1>
  <Information xmlns:py="http://codespeak.net/lxml/objectify/pytype" py:pytype="str">maybe</Information>
</Test>

As pointed out here : When using lxml, can the XML be rendered without namespace attributes?, this is enough to prevent this xmlns markup to appear :

objectify.deannotate(root, xsi_nil=True)
etree.cleanup_namespaces(root)

    from lxml version 2.3.2 you can pass `cleanup_namespaces=True` to `objectify.deannotate()` (no need to call `etree.cleanup_namespaces()`) – Pedru Mar 24 '16 at 10:54
