How can I use Google Map Feed API to get a list of my Google Maps using Python?

I want to create a script in Python which downloads the current KML files of all the Maps I created on Google Maps.

To do so manually, I can use this:

http://maps.google.com.br/maps/ms?msid=USER_ID.MAP_ID&msa=0&output=kml

where USER_ID is a constant number Google uses to identify me, and MAP_ID is the individual map identifier generated by the link icon on top-right corner.

This is not very straightforward, because I have to manually browse "My Places" page on Google Maps, and get the links one by one.

From Google Maps API HTTP Protocol Reference:

The Map Feed is a feed of user-created maps.

This feed's full GET URI is:

http://maps.google.com/maps/feeds/maps/default/full

This feed returns a list of all maps for the authenticated user.

** The page says this service is no longer available, so I wonder if there is a way to do the same in the present.

So, the question is: Is there a way to get/download the list of MAP_IDs of all my maps, preferrably using Python?

The correct answer to this question involves using Google Maps Data API, HTML interface, which by the way is deprecated but still solves my need in a more official way, or at least more convincing than parsing a web page. Here it goes:

# coding: utf-8

import urllib2, urllib, re, getpass

username = 'heltonbiker'
senha = getpass.getpass('Senha do usuário ' + username + ':')

dic = {
        'accountType':      'GOOGLE',
        'Email':            (username + '@gmail.com'),
        'Passwd':           senha,
        'service':          'local',
        'source':           'helton-mapper-1'
        }
url = 'https://www.google.com/accounts/ClientLogin?' + urllib.urlencode(dic)
output = urllib2.urlopen(url).read()
authid = output.strip().split('\n')[-1].split('=')[-1]

request = urllib2.Request('http://maps.google.com/maps/feeds/maps/default/full')
request.add_header('Authorization', 'GoogleLogin auth=%s' % authid)
source = urllib2.urlopen(request).read()

for link in re.findall('<link rel=.alternate. type=.text/html. href=((.)[^\1]*?)>', source):
    s = link[0]
    if 'msa=0' in s:
        print s

I arrived with this solution with a bunch of other questions in SO, and a lot of people helped me a lot, so I hope this code might help anyone else trying to do so in the future.

A quick and dirty way I have found, that skips Google Maps API completely and perhaps might brake in the near future, is this:

# coding: utf-8

import urllib, re
from BeautifulSoup import BeautifulSoup as bs

uid = '200931058040775970557'
start = 0
shown = 1

while True:
    url = 'http://maps.google.com/maps/user?uid='+uid+'&ptab=2&start='+str(start)
    source = urllib.urlopen(url).read()
    soup = bs(source)
    maptables = soup.findAll(id=re.compile('^map[0-9]+$'))
    for table in maptables:
        for line in table.findAll('a', 'maptitle'):
            mapid = re.search(uid+'\.([^"]*)', str(line)).group(1)
            mapname = re.search('>(.*)</a>', str(line)).group(1).strip()[:-2]
            print shown, mapid, mapname
            shown += 1

            # uncomment if you want to download the KML files:
            # urllib.urlretrieve('http://maps.google.com.br/maps/ms?msid=' + uid + '.' + str(mapid) +
                               '&msa=0&output=kml', mapname + '.kml')                

    if '<span>Next</span>' in str(source):
        start += 5
    else:
        break

Of course it is only printing a numbered list, but from there to save a dictionary and/or automate KML download via &output=kml url trick it goes naturally.
