I'm currently trying ElementTree and it looks fine, it escapes HTML entities and so on and so forth. Am I missing something truly wonderful I haven't heard of?

This is similar to what I'm actually doing:

import xml.etree.ElementTree as ET
root = ET.Element('html')
head = ET.SubElement(root,'head')
script = ET.SubElement(head,'script')
script.set('type','text/javascript')
script.text = "var a = 'I love á letters'"
body = ET.SubElement(root,'body')
h1 = ET.SubElement(body,'h1')
h1.text = "And I like the fact that 3 > 1"
tree = ET.ElementTree(root)
tree.write('foo.xhtml')

# more foo.xhtml
<html><head><script type="text/javascript">var a = 'I love &amp;aacute;
letters'</script></head><body><h1>And I like the fact that 3 &gt; 1</h1>
</body></html>

https://github.com/galvez/xmlwitch:

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)

don't you actually want something like:

html(head(script(type='text/javascript', content='var a = ...')),
body(h1('And I like the fact that 3 < 1'), p('just some paragraph'))

I think I saw something like that somewhere. This would be wonderful.

EDIT: Actually, I went and wrote a library today to do just that: magictree

You can use it like this:

from magictree import html, head, script, body, h1, p
root = html(
         head(
           script('''var a = 'I love &amp;aacute; letters''', 
                  type='text/javascript')),
         body(
           h1('And I like the fact that 3 > 1')))

# root is a plain Element object, like those created with ET.Element...
# so you can write it out using ElementTree :)
tree = ET.ElementTree(root)
tree.write('foo.xhtml')

The magic in magictree lies in how the importing works: The Element factories are created when needed. Have a look at the source, it is based on an answer to another StackOverflow question.
