搜索XML属性以解析XML元素

Question

我正在尝试基于某些XML属性解析XML元素。我的XML文件是：

<?xml version="1.0" encoding="utf-8"?>
<products updated="9/1/2017">
  <product name="o365">
    <addresslist type="IPv6">
      <address>2603:1020:200::682f:a1d8/128</address>
      <address>2603:1020:201::3c4/128</address>
      <address>2603:1030:603::6a/128</address>
      <address>2603:1030:603::72/128</address>

我不能让我的代码工作，但我怀疑有一个更好的方法来解决这个问题。如果product name=“o365”和addresslist是“type=“IPv6”，我想获取所有地址元素。我的代码是：

tree = ET.fromstring(r.text)

for node in tree.iter('product'):
    list = node.attrib.get('addresslist')
    address = node.attrib.get('address')
    if list and address:
        print '  %s :: %s' % (list, address)
    else:
        print name

这对我很有用：

import xml.etree.ElementTree as ET

tree = ET.parse('1.xml')

for x in tree.iter('product'):
if x.attrib.get('name') == 'o365':
    for y in tree.iter('addresslist'):
        if y.attrib.get('type') == 'IPv6':
            for z in tree.iter('address'):
                print z.text

具有以下输出：

2603:1020:200::682f:a1d8/128 
2603:1020:201::3c4/128
2603:1030:603::6a/128
2603:1030:603::72/128
