Here's another way to walk an ElementTree.  This one creates a hash of hashes which are normally more useful than tuples for property lookups.

import xml.etree.ElementTree as ET

tree = ET.ElementTree(file = "foo.xml")
d = {}
for ds in tree.findall("datasource"):

	name = ds.find('name').text
	d[name] = {}
	print 'datasource =', name

	for i in ds.findall('*'):
	#for i in ds.getiterator():  # also works

		if i.tag in ('datasource', 'name'):
			continue

		print '    ',i.tag, "=", i.text
		d[name][i.tag] = i.text

	print

print d
