將python中的當前時間與xml中的時間進行比較

我正在使用python來解析XML文檔。我正在以XML格式列出時間。時間格式如下：將python中的當前時間與xml中的時間進行比較

<SCHEDULED_START_TIME>5:16:26 PM</SCHEDULED_START_TIME>

我需要將它與計算機中的當前時間進行比較。

基於比較，我需要將同一個節點中的數字分配給一個變量，然後將該變量傳送給另一個程序。數量是按以下格式：

<SCHEDULED_HOUSE_NAM>149</SCHEDULED_HOUSE_NAM>

這是我到目前爲止，但我做了比較之後，我要麼得到第一號或0（零）。

到目前爲止的代碼：

import xml.dom.minidom as minidom 
from datetime import datetime 

sponsorTimeArray = [] 
houseNumberArray = [] 
sponsorTimeIndex = 0 
currentHouseNumber = 0 


def readFeed(): 
    #myTime = datetime.now().strftime('%I:%M:%S %p').lstrip('0') 
    #print myTime 

    sponsorsXML = minidom.parse("/Users/jobregon/Desktop/test_output.xml") 

    sponsorTimes = sponsorsXML.getElementsByTagName("ITEM") 

    for sprTime in sponsorTimes: 
     currentTime = sprTime.getElementsByTagName("SCHEDULED_START_TIME")[0].firstChild.data 
     if currentTime not in sponsorTimeArray: 
      sponsorTimeArray.append(currentTime) 
# for each in sponsorTimeArray: 
#  print each 

    houseNumbers = sponsorsXML.getElementsByTagName("ITEM") 

    for hsNumber in houseNumbers: 
     currentHousNumber = hsNumber.getElementsByTagName("SCHEDULED_HOUSE_NAM")[0].firstChild.data 
     if currentHousNumber not in houseNumberArray: 
      houseNumberArray.append(currentHousNumber) 
# for each in houseNumberArray: 
#  print each 


    for i in sponsorTimeArray: 
     global sponsorTimeIndex 
     global currentHouseNumber 
     #print myTime 
     #currentHouseNumber = houseNumberArray[sponsorTimeIndex] 
     if datetime.now().lstrip('0') <= datetime.strptime(i,'%I:%M:%S %p'): 
      print 'running if' 
      currentHouseNumber = houseNumberArray[5] 
      break 
     sponsorTimeIndex += 1 


readFeed()

爲了讓時間比較工作，你需要做的是這樣：

sponsor_time = datetime.strptime(i, '%I:%M:%S %p').time() 
now_time = datetime.now().time() 
if now_time <= sponsor_time: 
    print('running if @ %s' % sponsor_time) 
    break

的這裏的關鍵要素是con將datetime.datetime轉換爲datetime.time以允許僅使用一天中的時間的比較，並忽略日期。

感謝您的回覆。現在我可以同時得到兩個數字，但計算機的時間是24小時的時間，而xml時間是12小時的時間，我認爲比較從不是真實的，所以打印和中斷從不運行。 – Matzunaga

XML有AM/PM，所以它工作正常。 –
