Question

我正在使用python来解析XML文档。我得到了XML中列出的时间。时间采用以下格式：

<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。

根据比较，我需要将同一节点中的数字分配给一个变量，然后该变量将被传输到另一个程序。该号码采用以下格式：

<SCHEDULED_HOUSE_NAM>149</SCHEDULED_HOUSE_NAM>

这是我到目前为止所做的，但在比较之后，我要么得到第一个数字，要么得到0（零）。

到目前为止

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

Answer 1

要进行时间比较，您需要执行以下操作：

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

此处的关键元素是将datetime.datetime转换为datetime.time以允许仅使用时间的比较，并忽略日期。

将python中的当前时间与从xml解析的时间进行比较
