使用 xml.etree.ElementTree 获取子节点的所有实例

问题描述

我有以下 XML 文件作为输入:

I have the following XML file as input:

<Test>
  <callEvents>
    <moc>
      <causeForTermination>0</causeForTermination>
      <serviceCode>
        <teleServiceCode>11</teleServiceCode>
      </serviceCode>
      <dialledDigits>5555555</dialledDigits>
      <connectedNumber>77777</connectedNumber>
    </moc>

    <moc>
      <causeForTermination>0</causeForTermination>
      <serviceCode>
        <teleServiceCode>11</teleServiceCode>
      </serviceCode>
      <dialledDigits>2222222</dialledDigits>
    </moc>
  </callEvents>
  <callEventsCount>100</callEventsCount>
</Test> 

我想输出 dialledDigits 的所有值.但是，我的代码只显示 dialledDigits 的第一个实例.

I want to output all the values for dialledDigits. However, my code only displays the first instance of dialledDigits.

dialledDigits {} 5555555

我想要的输出应该包含这两个实例.

My desired output should contain both instances.

dialledDigits {} 5555555
dialledDigits {} 2222222

这是我的代码

import xml.etree.ElementTree as ET
tree = ET.parse('as.xml')
root = tree.getroot()
callevent=root.find('callEvents')

Moc1=callevent.find('moc')

for node in Moc1.getiterator():
    if node.tag=='dialledDigits':
        print node.tag, node.attrib, node.text

推荐答案

使用findall:

moc1 = callevent.findall('moc')

for moc in moc1:
    for node in moc.getiterator():
        if node.tag=='dialledDigits':
            print node.tag, node.attrib, node.text

输出:

dialledDigits {} 5555555
dialledDigits {} 2222222
