Python讀取xml報錯解析--ExpatError: not well-formed (invalid token)

xml文件內容如代碼所示存入的名字為login.xml：

<?xml version="1.0" encoding="utf-8"?>
<info>
   <explain>126</explain>
      <url>http://www.126.com</url>
      <null username="" password="">請先輸入您的郵箱帳號</null>
      <pawd_null username="testingwtb" password=""></pawd_null>
      <user_null username="" password="a123456">
      </user_null>
      <error username="xxx" password="xxx"></error>
</info>

Python源代碼代碼本身是沒有錯誤的：

#coding =utf-8
import xml.dom.minidom

dom=xml.dom.minidom.parse('D:\Python27\lianxidanma\login.xml')
root = dom.documentElement
logins=root.getElementsByTagName('null')
username=logins[0].getAttribute("username")
password=logins[0].getAttribute("password")
prompt_info = logins[0].firstChild.data

print username
print prompt_info

 

使用xml.dom.mindom庫解析xml文件時，報如下錯誤：

Traceback (most recent call last):
  File "D:\Python27\lianxidanma\xml11.py", line 4, in <module>
    dom=xml.dom.minidom.parse('D:\Python27\lianxidanma\login.xml')
  File "D:\Python27\lib\xml\dom\minidom.py", line 1918, in parse
    return expatbuilder.parse(file)
  File "D:\Python27\lib\xml\dom\expatbuilder.py", line 924, in parse
    result = builder.parseFile(fp)
  File "D:\Python27\lib\xml\dom\expatbuilder.py", line 207, in parseFile
    parser.Parse(buffer, 0)
ExpatError: not well-formed (invalid token): line 5, column 36

其實報這個錯誤主要還是“轉碼”的問題，如果xml文件中沒有中文，自然能夠輸入所需要的數據，但是現在xml文件中有中文。

一般情況我們在做自動化測試的時候，習慣用txt來編輯xml文件進行數據保存，但是在用txt編輯完xml文件后，都習慣性的直接點擊保存，默認保存的編碼方式是ANSI

問題就出在編碼方式，如果我們用UTF-8的編碼方式保存后，重新執行腳本，那么程序執行成功，正確輸出中文：
