xml parsing issue in tmp.xml file

[itsmemala]

I get the following error when running main.py. How can I resolve this please ?

Note:

1. I'm running on a windows machine
2. I am running the code for main.py line by line on a jupyter notebook (in the same dir as main.py)

tmp.txt I've converted the tmp.xml file to .txt and attached here for your refernece -> It appears it's not in xml format.
