<Config id="1A" cId="1A13" name="Confg 13">
<Assignment _id="id1eF" of_end_="id1588"/>
<Assignment _id="id1F0" of_end_="id1598" />
</Config>

<Config id="2A" cId="2A14" name="Confg 14">
<Assignment _id="id1eF" of_end_="id151"/>
<Assignment _id="id1F0" of_end_="id152" />
</Config>


<Config id="3A" cId="3A15" name="Confg 14">
<Assignment _id="id1eF" of_end_="id153"/>
<Assignment _id="id1F0" of_end_="id154" />
</Config>
<ele id="id1ef" name="name1"/>
<ele id="id1f0 name="name2"/>
</rootdata>

tree = ET.parse('data.xml')
root = tree.getroot()


for config in root.findall("./Config/[@cId='1A13']/Assignment"):

temp_id=config.attrib['_id']
temp_of_end=config.attrib['of_end_']
