Having the following xml,
<markets xmlns:cap="URI">
    <us>
        <summary>
            <index>NASDAQ</index>
            <last>34,000</last>
            <cap:change>-2.4</cap:change>
        </summary>
    </us>
</markets>
Let's assume I've an Element that points to NASDAQ,
import xml.etree.ElementTree as ET
markets = ET.parse('markets.xml')
// some processing here
index = # pointing to `NASDAQ` element here
how can I get the element full path as markets.us.summary.index?
