我花了好几个小时寻找这个问题的解决方案，但都空手而归。我正在尝试在 Python 中解析 xml 文档以将元素作为逗号分隔的列表返回。

这里是一个xml文档的例子：

<?xml version="1.0" encoding="utf-8"?>

  <DestinationUrlPerformanceReportColumns>
    <Column name="GregorianDate" />
    <Column name="AccountName" />
    <Column name="CampaignName" />
    <Column name="CampaignId" />
    <Column name="AdGroupName" />
    <Column name="AdGroupId" />
    <Column name="DestinationUrl" />
    <Column name="Impressions" />
    <Column name="Clicks" />
    <Column name="Spend" />
    <Column name="Conversions" />
  </DestinationUrlPerformanceReportColumns>
  <Table>
    <Row>
      <GregorianDate value="4/7/2014" />
      <AccountName value="BingAccount" />
      <CampaignName value="Campaign#1" />
      <CampaignId value="12345678" />
      <AdGroupName value="Adgroup1" />
      <AdGroupId value="901234567" />
      <DestinationUrl value="www.example.com" />
      <Impressions value="8" />
      <Clicks value="0" />
      <Spend value="0.00" />
      <Conversions value="0" />
    </Row>
    <Row>
      <GregorianDate value="4/7/2014" />
      <AccountName value="BingAccount" />
      <CampaignName value="Campaign#2" />
      <CampaignId value="83984398493" />
      <AdGroupName value="Adgroup#2" />
      <AdGroupId value="3439843983" />
      <DestinationUrl value="www.example.co.uk" />
      <Impressions value="20" />
      <Clicks value="2" />
      <Spend value="0.10" />
      <Conversions value="0" />
    </Row>
  </Table>

我想在逗号分隔的列表中返回每一行的值，所以想要的结果是： ('4/7/2014','BingAccount','Campaign#1','12345678','Adgroup1','901234567','www.example.com','8','0','0.00' ,'0') ('4/7/2014','BingAccount','Campaign#2','83984398493','Adgroup2','3439843983','www.example.co.uk','20','2',' 0.10','0')

这是我目前所拥有的，但无法进一步推进：

from xml.dom import minidom

xmldoc = minidom.parse('file.xml')

rows = xmldoc.firstChild.childNodes[3].childNodes

for i in rows:
    print tuple(i.childNodes)

试试xml.etree。
