Parsing an xml in python to find xpaths of all elements (nodes)

I have an xml file- https://github.com/schogini/jVoiD/blob/master/Modules/jVoidCustomers/src/main/webapp/WEB-INF/spring/webcontext/DispatcherServlet-context.xml

I am using the following code to parse a xml file-

 from lxml import etree
 xslt_root = etree.parse("/Users/cbuser1/CodeBlueFabricator/src/poc/PythonParser/mvc-config.xml")
 print(xslt_root)

I get the result of my program as-

<lxml.etree._ElementTree object at 0x10e95bcc8>

Now I need to loop through this object and get the xpath of every element in it. (every single element inside the xml file). Any ideas?

Actually I was able to find a solution. I converted my XML file to JSON using this-

import json
import xmltodict
with open("INSERT XML FILE LOCATION HERE", 'r') as f:
    xmlInString = f.read()
print("The xml file read-")
print(xmlInString)
JsonedXML = json.dumps(xmltodict.parse(xmlString), indent=4)
print("\nJSON format of read xml file-")
print(JsonedXML)
with open("myJson.json", 'w') as f:
    f.write(JsonedXML)

And then I went through the json and found all the innermost nodes and saved their key and value in a txt file using this-

import json

data = json.load(open('GIVE LOCATION OF THE CONVERTED JSON HERE'))
token_key_value_dictionary=[]
only_tokens_dictionary=[]
uniqueKey ='xml'
def recursive_json_parser(start_point_value,uniqueKey,start_point_key=''):
    if start_point_key !='':
        uniqueKey += '.'+start_point_key
    if type(start_point_value) is str or type(start_point_value) is unicode:
        token_key_value_dictionary.append([str(uniqueKey),str(start_point_value)])
        only_tokens_dictionary.append(str(start_point_value))
        uniqueKey =''
    elif type(start_point_value) is list:
        for i in start_point_value:
            recursive_json_parser(i,uniqueKey)
    else:
        for key,value in start_point_value.items():
            recursive_json_parser(value,uniqueKey,key)

for key,value in data.items():
    print (len(value))
    recursive_json_parser(value,uniqueKey,key)

f = open('tokens.txt','w')
for row in only_tokens_dictionary:
    print (row)
    if row!='':
        f.write(row+'\n')
f.close()

In the 2nd program, I went through the json-consisting of lists, and dictionaries to reach in to the innermost nodes consisting only of a key and a value and no more list or dictionary inside it.
