I am using Python 3.1, but I can't figure out why I can't use
xml.dom.minidom.  Here is my code:

from xml.dom.minidom import parse, parseString
url = 'http://minnesota.publicradio.org/tools/podcasts/
grammar_grater.xml'  #just for test purposes

doc = parse(url)  #I have also tried parseString(url), not to mention
a million other methods from xml.Etree, xml.sax etc...  all to no
avail


What the heck am I doing wrong?  How can I get this xml file and use
the toprettyxml() method.  Or something, so I can parse it.  I don't
have any books and the documentation for Python kind of sucks.  I am a
complete noob to Python and internet programming.  (I'm sure that is
obvious :) )

Thanks!
