Does this answer your question? How do I parse XML in Python? — buran

If you are "able to get the attribute name" then please show the code you have so far, and show the output you expect. Thanks. stackoverflow.com/help/minimal-reproducible-example — Mathias Müller

See below

import xml.etree.ElementTree as ET


xml = '''<annotations>
      <image height="940" id="0" name="90.jpg" width="1820">
        <box label="Objects" occluded="1" xbr="255" xtl="0" ybr="624" ytl="509">
         <attribute name="Class">Car</attribute>
         <attribute name="Occlusion %">25-50%</attribute>
         <attribute name="Truncation %">0%</attribute>
        </box>
      </image>
    </annotations>'''

#
# Find the attribute element (under box element) where the attribute name value is 'Class'. print the text of the element text
#
root = ET.fromstring(xml)
print(root.find(".//box/attribute[@name='Class']").text)
