Question

尝试创建python脚本来显示来自复杂XML文件的数据，该文件每5-7秒更改一次。下面是我正在使用的示例XML文件...

<bsgame source="TAS Baseball/Softball" version="5.17.00" 
generated="4/9/2019">
<venue gameid="SB0409-1"
       visid="IUP-S" homeid="JOHN" visname="Indiana (PA)" 
homename="Seton Hill"
       date="4/9/2019" location="Greensburg, PA"

       leaguegame="N" start="3:00 PM" dhgame="1"

  <lineinn inn="6" score="1"></lineinn>
  <lineinn inn="7" score="3"></lineinn>
</linescore>

  <lineinn inn="6" score="1"></lineinn>
  <lineinn inn="7" score=""></lineinn>
</linescore>

我已经注意到，诸如StretchInternet之类的服务将这样的XML转换为Json以便显示数据。我已经弄清楚了如何在Python中使用xmltodict将XML转换为Json。

 import json
 import xmltodict

 with open("/Volumes/GoogleDrive/My Drive/LIVE/XMLs/SB_Demo.xml", 'r') as f:
     xmlString = f.read()

 jsonString = json.dumps(xmltodict.parse(xmlString), indent=4)

 print("\nJSON output(output.json):")
 print(jsonString)

 with open("output.json", 'w') as f:
     f.write(jsonString)

我很困惑从这里去哪里。最终，我希望能够在视频广播中显示两个“团队”的全部RUNS（@runs）。但是，我是一个循序渐进的家伙。步骤1 ...如何使用xmltodict解析此XML，并仅显示两个团队的@runs？

对于初学者，您应保持与报价用法一致（使用“或”）

此外，您的xml在每个<linescore>之后缺少json.dumps结束标记

关于您的问题-您正在使用with open("YOUR_XML_FILE.xml", 'r') as f: xmlString = f.read() xmlDict = xmltodict.parse(xmlString) for team in xmlDict['bsgame']['team']: print(team['@name'], 'Runs :') print(team['linescore']['@runs'])将xml字典转换为JSON字符串，这对于您尝试的操作将无用。将您的xmltodict对象作为Python dict访问
