xmlwitch

undefinedxmlwitch is a BSD-licensed, Python 2.5+ library that offers
idiomatic XML generation through context managers (with statement) in a
minimalist implementation with less than 100 lines of code. To install,
just run pip install xmlwitch, easy_install xmlwitch or copy
undefinedxmlwitch.py to your appropriate project’s directory. It’s just one
file.

import xmlwitch
xml = xmlwitch.Builder(version='1.0', encoding='utf-8')
with xml.feed(xmlns='http://www.w3.org/2005/Atom'):
    xml.title('Example Feed')
    xml.updated('2003-12-13T18:30:02Z')
    with xml.author:
        xml.name('John Doe')
    xml.id('urn:uuid:60a76c80-d399-11d9-b93C-0003939e0af6')
    with xml.entry:
        xml.title('Atom-Powered Robots Run Amok')
        xml.id('urn:uuid:1225c695-cfb8-4ebb-aaaa-80da344efa6a')
        xml.updated('2003-12-13T18:30:02Z')
        xml.summary('Some text.')
print(xml)
