# 1. How to read and XML file using Python ?
# For example purpose, kindly save the above XML content into a file named as 'data.xml'
# import a class named xml.etree.ElementTree

import xml.etree.ElementTree as element_tree

# Before reading we should parse the whole XML file content as tree
tree = element_tree.parse('data.xml')

# Now with tree we have to fetch the root
