Coding an XML document with python?

Question

I am currently taking part in a Cyber Challenge, however I have beeen asked to produce an xml file which contains nodes and atributes:

Generate a valid xml file at /tmp/vulnerable-countries.xml.
It should contain a list of country nodes attached to a root node
that have name attributes, the third node should be Panama.

I have looked everywhere for information on this and I cam up with the following. However, after submitting this code I get the following:

import xml.etree.cElementTree as ET

root = ET.Element("root")
ET.SubElement(root, "Country")
ET.SubElement(root, "Country")
ET.SubElement(root, "Panama")
tree = ET.ElementTree(root)
tree.write("/tmp/vulnerable-countries.xml")

Format of /tmp/vulnerable-countries.xml was not correct. It should contain 3 country nodes with name attributes, with the third being Panama.

Can anyone help?

The error message indicates that you need to include an attribute called name for each of your country nodes. Try this:

import xml.etree.cElementTree as ET

root = ET.Element("root")
ET.SubElement(root, "country", name="Narnia")
ET.SubElement(root, "country", name="Wakanda")
ET.SubElement(root, "country", name="Panama")
tree = ET.ElementTree(root)
tree.write("/tmp/vulnerable-countries.xml")

Result:

<root><country name="Narnia" /><country name="Wakanda" /><country name="Panama" /></root>
