XML Parse attributes using namespace

Question

I'm using the following XML:

<feed xmlns:im="http://itunes.apple.com/rss" xmlns="http://www.w3.org/2005/Atom" xml:lang="en">
<id>
https://itunes.apple.com/IN/rss/topfreeapplications/limit=200/xml

I would like to extract the id information for each entry value: the attribute is as follows: "im:id"

from xml.dom import minidom
xmldoc = minidom.parse('topIN.xml')
itemlist = xmldoc.getElementsByTagName('link')
print(len(itemlist))
print(itemlist[0].attributes.keys())

I get information: 1 [u'href', u'type', u'rel']

But when I do the same of id, nothing returns.

Here is a version using xml.etree.ElementTree:

import xml.etree.ElementTree as ET

tree = ET.parse('topIN.xml')
root = tree.getroot()
ns={'im':"http://itunes.apple.com/rss", 'atom':"http://www.w3.org/2005/Atom"}
for id_ in root.findall('atom:entry/atom:id', ns):
    print (id_.attrib['{' + ns['im'] + '}id'])

Here is a version using lxml:

from lxml import etree
root=etree.parse('topIN.xml')
ns={'im':"http://itunes.apple.com/rss", 'atom':"http://www.w3.org/2005/Atom"}
print('\n'.join(root.xpath('atom:entry/atom:id/@im:id', namespaces=ns)))

This worked:

   from xml.dom import minidom
    xmldoc = minidom.parse('topIN.xml')
    itemlist = xmldoc.getElementsByTagName('entry')
    print(len(itemlist))
    for s in itemlist:
        print s.getElementsByTagName('id')[0].attributes['im:id'].value
