XML : Python parse an xml file pass result to array

I am attempting to parse an xml file which I have accomplished and pass the results into an array which will be used later on. The xml is opened read and parsed where I am picking out 3 elements (channel, start and title). As shown in code below, the start is date and time. I am able to split date and time and store in date. As the code loops thru each xml entry I would like to pick out the channel, start and title and store to a multidimensional array. I have done this in Brightscript but can't understand the array or list structure of Python. Once I have all entries in the array or list, I will need to parse that array pulling out all titles and dates with the same date. Can somebody guide me thru this?

       xmldoc=minidom.parse (xmldoc)        programmes= xmldoc.getElementsByTagName("programme")         def getNodeText(node):       nodelist = node.childNodes      result = []      for node in nodelist:        if node.nodeType == node.TEXT_NODE:            result.append(node.data)       return ''.join(result)      title = xmldoc.getElementsByTagName("title")[0]      #print("Node Name : %s" % title.nodeName)      #print("Node Value : %s \n" % getNodeText(title))        programmes = xmldoc.getElementsByTagName("programme")          for programme in programmes:        cid = programme.getAttribute("channel")        starts=programme.getAttribute("start")        cutdate=starts[0:15]        year= int(cutdate[0:4])        month= int(cutdate[5:6])        day= int(cutdate[7:8])        hour= int(cutdate[9:10])        minute= int(cutdate[11:12])        sec= int(cutdate[13:14])        date=datetime(year, month, day,hour, minute, sec)        title = programme.getElementsByTagName("title")[0]          print("id:%s, title:%s, starts:%s" %              (cid, getNodeText(title), starts))        print (date)
