xml解析不出来

Question

import xml.etree.ElementTree as ET
root = ET.fromstring('<?xml version="1.0" encoding="utf-8" ?><root><cpid>1398</cpid><ret_result>1007</ret_result><cp_order_no>0</cp_order_no><id>0</id></root>')
a=root.find('root')
print(str(a))

为什么结果是None?
a=root.find('root').txt就直接报错了，NoneType has no attribute .txt

Answer 1

import xml.etree.ElementTree as ET
root = ET.fromstring('<?xml version="1.0" encoding="utf-8" ?><root><cpid>1398</cpid><ret_result>1007</ret_result><cp_order_no>0</cp_order_no><id>0</id></root>')

print(root.find('cpid').text)
print(root.find('ret_result').text)
