Try 4Suite / Amara: 
http://uche.ogbuji.net/uche.ogbuji.net/tech/4suite/amara/ (I downloaded 
the allinone package)

 >>> from Ft.Xml import Parse
 >>> from Ft.Xml.Domlette import PrettyPrint
 >>> xmlfile = open('c:/test.xml')
 >>> xml = "".join(xmlfile.readlines())
 >>> xml
'<xml><level1><level2>some text<level3>level 3</level3></level2>some 
other text</level1><another>Hi!<empty /></another></xml>\n'
 >>> doc = Parse(xml)
 >>> PrettyPrint(doc)
<?xml version="1.0" encoding="UTF-8"?>
    <level2>some text<level3>level 3</level3>
    </level2>some other text</level1>

It isn't a great representation... Perhaps my xml was malformed. Try it 
yourself to see if it works for you.
