pandas-read-xml has error on 'json-normalize'

Question

I saw there is a way to directly read XML files using pandas. I followed and used this package. However, I keep getting errors.

https://pypi.org/project/pandas-read-xml/

import pandas as pd
import pandas_read_xml as pdx
from pandas.io.json import json_normalize

The error was generated by last line and the error is

ImportError: cannot import name 'json_normalize'

I am using kernel python 3, can anyone tell me what was wrong with it?
