reverse the nesting of elements with python lxml.etree

I'm looking for a recipe for python's lxml.etree that will reverse the nesting of elements, turning:

<text>
    <name>
        <ref>foobar</ref>
    </name>
</text>

into:

<text>
    <ref>
        <name>foobar</name>
    </ref>
</text>

I've a feeling this is obvious, but I'm not seeing it.

Something like this?

import lxml.etree as et
from lxml.builder import E

xml = """
<text>
    <name>
        <ref>foobar</ref>
    </name>
</text>
"""

tree = et.fromstring(xml)

for name in tree.findall('name'):
    text = name.find('ref').text
    tree.replace(name, E.ref(E.name(text)))

print et.tostring(tree)
