This is my code. I want to find the value of the Tag from "DEFINITION-REF", which is 'DEST'='ECUC-ENUMERATION-PARAM-DEF'. But I am not able to get the value of 'DEST'. when I run the below code, it is always 'None'. Can you provide any solutions?

Code:

    import xml.etree.ElementTree as ET
    import csv
    fpath = 'sample1.arxml'

    tree = ET.parse(fpath)
    root = tree.getroot()

    ns = {'ns': 'http://autosar.org/schema/r4.0'}
    for param1 in root.findall('.//ns:DEFINITION-REF/',  namespaces=ns):
        value = param1.get('DEST')
        print(value)

Solution

I used the file you shared and was able to get the attributes for DEFINITION-REF :

import xml.etree.ElementTree as ET

root = ET.parse('test.xml').getroot()


#run this, and it will list the key value pairs for DEFINITION-REF element : 
for entry in root.findall(".//{http://autosar.org/schema/r4.0}DEFINITION-REF"):
    print(entry.attrib)
