Using ElementTree you can do this:

import xml.etree.ElementTree as ET

def sortchildrenby(parent, attr):
    parent[:] = sorted(parent, key=lambda child: child.get(attr))

tree = ET.parse('input.xml')
root = tree.getroot()

sortchildrenby(root, 'NAME')
for child in root:
    sortchildrenby(child, 'NAME')

tree.write('output.xml')
