XML parsing: set great-great-...-grandchild element as a root in Python

I have a XML file which has structure like this:

<element1>
    <element2>
        ...
        <element10 name="a">
            ...

I am trying to parse this file in Python 2.7, using The ElementTree XML API. But the data I am looking for are deeply hidden in the structure.

Is there any way I can set specific great-great-...-grand child element (for example the element10) as the root element without iterating the whole structure?
