如何从xml标记打印字符串列表

Question

我正在使用我的python脚本从我自己的xml文件中打印字符串列表。

我正在尝试找出如何从程序通道标记中打印字符串列表，以获取start =“”和stop =“”标记中的格式。当我想要获取格式和标题列表时，我只会获得您可以在此处看到的频道列表：

这是xml：

<tv generator-info-name="www.mysite.com/xmltv">
<channel id="101 ABC FAMILY">
<display-name>101 ABC FAMILY</display-name>
<programme channel="101 ABC FAMILY" start="" stop="20140517070000">
<title lang="en">The Karate Kid Part III</title>
<sub-title lang="en"></sub-title>
<desc lang="en"></desc>
<category lang="en"></category>
</programme>
<programme channel="101 ABC FAMILY"start="20140517070000" stop="20140517093000">
<title lang="en">The Karate Kid</title>
<sub-title lang="en"></sub-title>
<desc lang="en"></desc>
<category lang="en"></category>
</programme>
</channel>

以下是代码：

#DOWNLOAD THE XML SOURCE HERE
url = ADDON.getSetting('allchannels.url')
req = urllib2.Request(url)
response = urllib2.urlopen(req)
data = response.read()
response.close()
profilePath =xbmc.translatePath(os.path.join('
special://userdata/addon_data/script.tvguide', ''))

if os.path.exists(profilePath):
  profilePath = profilePath + 'source.db'
  con = database.connect(profilePath)
  cur = con.cursor()
  cur.execute('CREATE TABLE programs(id TEXT, channel TEXT, title TEXT, 
start_date TIMESTAMP, end_date TIMESTAMP, description TEXT)')
  con.commit()
  con.close
  tv_elem =ElementTree.parse(StringIO.StringIO(data)).getroot()

  profilePath =xbmc.translatePath(os.path.join('special://userdata/addon_data/script.tvguide', ''))
  profilePath = profilePath + 'source.db'
  con = database.connect(profilePath)
  cur = con.cursor()
  channels = OrderedDict()

  for elem in tv_elem.getchildren():
    if elem.tag == 'channel':
       channels[elem.attrib['id']] =self.load_channel(elem)
    elif elem.tag == 'programme':
       # get channel
       channel =channels[elem.attrib['programme']]
       channel =channels[elem.attrib['title']]
       # load program in channel
       channel.get_programs().append(self.load_programme(elem))
       for channel_key in channels:
         channel = channels[channel_key]
         display_name =channel.get_display_name()
         print channel.get_display_name()

您能否帮我解释如何从标题标签中的start =“”和stop =“”标签打印格式列表？
