我试图提取<player>中的项的数据值，这些项都位于根<players>

^{pr2}$

它工作正常（这不是提取items值，而是提取<player>中的内容），但它不能处理错误：

player =  c.find('.//player').text
AttributeError: 'NoneType' object has no attribute 'text'

这很令人困惑，因为它似乎对其他人都有效。如果我做错了，正确的方法是什么？在

Answer 1

下面是如何为每个player元素获取items属性的值：

from xml.etree import ElementTree as etree

root = etree.parse("players.xml")
players = root.findall('player')
for p in players:
    items = p.get("items")  
    print items

输出：

^{pr2}$
