Python 解析XML文件以根据子元素检索父元素

我想解析一个xml文件，这是我的xml文件：

<group>
  <name>Services</name>
  <file>
    <name>Path\File1.c</name>
  </file>
  <file>
    <name>Path\File2.c</name>
    <excluded>
      <configuration>Configuration1</configuration>
      <configuration>Configuration2</configuration>
    </excluded>
  </file>
  <file>
    <name>Path\File3.c</name>
    <excluded>
      <configuration>Configuration2</configuration>
      <configuration>Configuration3</configuration>
    </excluded>
  </file>
  <file>
    <name>Path\File4.c</name>
  </file>
</group>

---

如果当前配置不包括此文件，我不知道如何继续检查每个文件

我不确定你到底想做什么，但也许这段代码可以帮助你

from lxml import etree

def getSourceFile(sTree, szConfigName):
#retrieve every file used in the project
lSource = []
for data in sTree.xpath('/group'):
  file = data.findall("file")
  for x in file:
    myName = ""
    confIsExcluded=False
    for element in x:
      if(element.tag == "name"):
        myName = element.text
      if(element.tag == "excluded"):
        configurations = [config.text for config in element.findall("configuration")]
        if(szConfigName in configurations):
          confIsExcluded=True
    if(not confIsExcluded):
      lSource.append(myName)
print(lSource)

if __name__ == '__main__':
  sTree = etree.parse("myXmlFile.xml")
  lConfigName = ["Configuration1", "Configuration1", "Configuration2", "Configuration3"]

  for iIdxConfig in range(0, len(lConfigName)):
  getSourceFile(sTree, lConfigName[iIdxConfig])
  print("\n\n")

显示您的预期结果为什么在

lConfigName

中存在

“Configuration1”

两次？我指的是从Configuration1到configuration4。预期结果是：['File1'，File3'，File4']#对于配置1，['File1'，File4']#对于配置2，['File1'，File2'，File4']#对于配置3，['File1'，File2'，File3'，File4']#对于配置4，谢谢，请注意，我编辑了列表lConfigName，其中有一个错误，并在Configuration1中写入了两次，而不是从Configuration1到Configuration4

from lxml import etree

def getSourceFile(sTree, szConfigName):
#retrieve every file used in the project
lSource = []
for data in sTree.xpath('/group'):
  file = data.findall("file")
  for x in file:
    myName = ""
    confIsExcluded=False
    for element in x:
      if(element.tag == "name"):
        myName = element.text
      if(element.tag == "excluded"):
        configurations = [config.text for config in element.findall("configuration")]
        if(szConfigName in configurations):
          confIsExcluded=True
    if(not confIsExcluded):
      lSource.append(myName)
print(lSource)

if __name__ == '__main__':
  sTree = etree.parse("myXmlFile.xml")
  lConfigName = ["Configuration1", "Configuration1", "Configuration2", "Configuration3"]

  for iIdxConfig in range(0, len(lConfigName)):
  getSourceFile(sTree, lConfigName[iIdxConfig])
  print("\n\n")
