解析XML与元素树

Question

我试图用ElementTree的解析XML，但我得到这个错误：

xml.etree.ElementTree.ParseError: encoding specified in XML declaration is incorrect 

我file.py：

from suds.client import Client 
import xml.etree.ElementTree as ET 

url = 'http://www.webservicex.com/globalweather.asmx?WSDL' 
client = Client(url) 
weather = client.service.GetWeather('Sao Paulo', 'Brazil') 
print weather 

parseWeather = ET.fromstring(weather) # >>>> Here I got my problem! 

当我尝试解析我的XML从串天气。任何人都知道如何解决这类问题？

Answer 1

的weather响应不的字符串：

>>> type(weather) 
<class 'suds.sax.text.Text'> 

但ElementTree的会把它变成文字。所要求的编码然而UTF16：

>>> weather.splitlines()[0] 
'<?xml version="1.0" encoding="utf-16"?>' 

打开这个响应转换成文本由它明确地编码到UTF-16：

>>> weather = weather.encode('utf16') 
>>> parseWeather = ET.fromstring(weather) 

Answer 2

虽然你不能确定文件的编码应该是，我试着将xml编码声明更改为utf-8，并且ElementTree能够解析它。
