This generates an XML declaration:
import xml.etree.ElementTree as ET
root = ET.Element('rss', version='2.0')
tree = ET.ElementTree(root)
tree.write('test.xml', encoding='iso-8859-1', xml_declaration=True)
However the declaration disappears if your don't pass an encoding. This doesn't match the documentation:
xml_declaration controls if an XML declaration should be added to the file. Use False for never, True for always, None for only if not US-ASCII or UTF-8 or Unicode (default is None).

As far as I can tell this was already working, even in 3.4.0a1 (the first pre-release of 3.4):
>>> tree.write('/dev/stdout', xml_declaration=True)
<?xml version='1.0' encoding='us-ascii'?>
<rss version="2.0" />
But it is not working in Python 2:
>>> tree.write('/dev/stdout', xml_declaration=True)
<rss version="2.0" />
Looking at the history, I am confused because a 3.2.3 revision (df8609f1854d) comes up in the history of 2.7’s /Doc/library/xml.etree.elementtree.rst. Perhaps it is just that the documentation has inherited some wording from Python 3. Possibly also relevant: revision 57e631f <https://bitbucket.org/mirror/cpython/commits/57e631f> and Issue 8047.

Python 2 is EOL, so I think this issue should be closed. |

Right, thanks. Closing since this works in Py3. |
