本文介绍了如何在Python中使用xml.etree.ElementTree模块处理XML文件，特别是聚焦于XPath表达式的应用，包括选择节点、获取属性和处理命名空间等关键操作。通过实例解析XML数据，帮助开发者更高效地读取和操作XML文档。

import xml.etree.ElementTree as ET
import os
def getXMLConfigNodeText(filePath,xPath):
    if (os.path.isfile(filePath)==False):
        return;
    root=ET.parse(filePath).getroot();
    nodetext=root.find(xPath).text
    if (nodetext==""):
        print("please check the node name is right!")
    #print(nodetext)
    return nodetext

import ReadXmlConfig
if __name__ == '__main__':
    scenarioFilePath=ReadXmlConfig.getXMLConfigNodeText("C:/HackXMLConfig.xml","ScenariosFilePath")
    xpath=ReadXmlConfig.getXMLConfigNodeText("C:/HackXMLConfig.xml","AddTheTestURLForAllScenaios/ScenaiorsXpath")
    url=ReadXmlConfig.getXMLConfigNodeText("C:/HackXMLConfig.xml", "AddTheTestURLForAllScenaios/AddedURL")
    print(scenarioFilePath)
    print(xpath)
    print(url)

默认 getroot =XMLTool 所以第一可以写成 ScenariosFilePath ，默认root 可以省略。
