将python中的当前时间与xml中的时间进行比较

我正在使用python来解析XML文档。我正在以XML格式列出时间。时间格式如下：将python中的当前时间与xml中的时间进行比较

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

我需要将它与计算机中的当前时间进行比较。

基于比较，我需要将同一个节点中的数字分配给一个变量，然后将该变量传送给另一个程序。数量是按以下格式：

<SCHEDULED_HOUSE_NAM>149</SCHEDULED_HOUSE_NAM>

这是我到目前为止，但我做了比较之后，我要么得到第一号或0（零）。

到目前为止的代码：

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()

为了让时间比较工作，你需要做的是这样：

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

的这里的关键要素是con将datetime.datetime转换为datetime.time以允许仅使用一天中的时间的比较，并忽略日期。

感谢您的回复。现在我可以同时得到两个数字，但计算机的时间是24小时的时间，而xml时间是12小时的时间，我认为比较从不是真实的，所以打印和中断从不运行。 – Matzunaga

XML有AM/PM，所以它工作正常。 –
