that's not the tree content, that's a serialized XML fragment.

the quickest way to do that is to serialize the entire element, and
strip off the start and end tags:

text = ElementTree.tostring(elem)
text = text.split(">", 1)[1].rsplit("<", 1)[0]

alternatively, you can serialize the subelements, and add in properly
encoded text and tail attributes:

def innersource(elem, encoding="ascii"):
    text = ElementTree._encode(elem.text or "", encoding)
    for subelem in elem:
        text = text + ElementTree.tostring(subelem)
        if subelem.tail:
            text = text + ElementTree._encode(subelem.tail, encoding)
    return text

(but _encode is not an official part of the elementtree API, so this code
may not work in post-1.2 releases)
