搜索XML属性来解析XML元素

Question

我想解析基于某些XML属性的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，但我怀疑有更好的方法来解决这个问题。我想所有地址元素;如果产品名称= “O365”和AddressList中是“TYPE =” IPv6" 的我的代码是：

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

这个工作对我来说：

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 

与下面的输出：

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