I don't know if you are aware of the BeautifulSoup module:


import BeautifulSoup as bs

xml = """<token pos="nn">Letterman</token><token pos="bez">is</
token><token pos="jjr">better</token><token pos="cs">than</
token><token pos="np">Jay</token><token pos="np">Leno</token>"""

doc = bs.BeautifulStoneSoup(xml)

tokens = doc.findAll("token")
for token in tokens:
    for attr in token.attrs:
        print "%s : %s" % attr


    print token.string

--output:--
pos : nn
Letterman
pos : bez
is
pos : jjr
better
pos : cs
than
pos : np
Jay
pos : np
Leno
