What about

-----------------------------------------
import lxml.etree as ET
from lxml.builder import E

h = E.Foo(
    dict(minie='1', moe='2'),
    E.Bar(
        dict(eenie='4'),
        E.Baz(meenie='3'),
        E.Baz(meenie='7')))

print ET.tostring(h, pretty_print=True)

----------------------------------------
<Foo moe="2" minie="1">
  <Bar eenie="4">
    <Baz meenie="3"/>
    <Baz meenie="7"/>
  </Bar>
</Foo>
---------------------------------------
