Description

Describe the bug

I am using the below imports to construct the XML but I am not parsing the XML with the any of the below module or sub module but still bandit it complaining( CWE-20) that do not use those module or sub modules to parse the XML. I think it will be good to raise the warning if the feature is used.

import i am using
from xml.etree.ElementTree import Element, SubElement, tostring

Reproduction steps
Create test.py and add below code

import xml.etree.ElementTree as et

root = et.Element("user")
name = et.SubElement(root, "name")
name.text = "John Doe"
email = et.SubElement(root, "email")
email.text = "john@example.com"
tree = et.ElementTree(root)
a = et.tostring(root).decode("utf-8")
print(a)

Then run the bandit scan
Expected behavior

I think it will be good to raise the warning if the feature is used.

Research direction

Start by creating the provided test.py reproduction and running Bandit 1.7.9 to confirm which warning is emitted for XML construction. Trace the XML-related check from that result and compare construction-only use with parsing use; done means construction code is not warned on while actual parsing remains covered.
