How Can I Extract Attribute Values from XML Nodes Using Python's ElementTree?

Parsing XML to Retrieve Node Attribute Instances

In the provided XML structure:

<foo>
   <bar>
      <type foobar="1"/>
      <type foobar="2"/>
   </bar>
</foo>

The task is to extract the values of the "foobar" attribute for each "type" node.

Solution Using ElementTree

The ElementTree module offers a convenient way to parse XML and access node attributes. Here's how you can implement it:

import xml.etree.ElementTree as ET

# Parse the XML
root = ET.parse('input.xml').getroot()

# Iterate over the "type" nodes
for type_tag in root.findall('bar/type'):
    # Get the value of the "foobar" attribute
    value = type_tag.get('foobar')

    # Print the value
    print(value)

This code will print the values "1" and "2", as desired.
