can modify an element, as shown here:

xml_dict["interface"]["ipv4"]["address"]["ip"] =
"192.168.55.3"You can see your changes in XML format by using the
unparse function (see Example 5-6). You can use the
pretty=True argument to format the XML to make it a
bit easier to read. XML doesn’t care about whitespace,
but humans do for readability.
