怎样优雅解决 python 解析 xml gb2312 编码的问题？

This topic created in 4274 days ago, the information mentioned may be changed or developed.

用Python解析编码为gb2312的xml，
<?xml version="1.0" encoding="gb2312" ?>
<node>...</node>
会报错：
ValueError: multi-byte encodings are not supported
试过ElementTree和minidom，都是如此。

最后采用了先解码再编码为utf8：
dstr = dstr.decode('gb2312').encode('utf-8'),
然后再字符串替换
dstr = dstr.replace('gb2312', 'utf-8')
才可以解析xml。很不优雅！

有什么好的解决方案？

@icedx Python3已经解决了中文字符编码问题了么? 冲着这个我也要升级到python3啊...

Python3 +1
先decode再encode的方法实在是悲摧

优雅的定义是什么

xml本来就应该统一成utf-8的编码，用gb也太不专业了吧

@pi1ot 优雅就是不粗暴

所有 Python 问题都可以用 «换 Python 3» 解决？

@wangleineo 请用 lxml。

@ZavierXu 大部分奇葩问题Py3都解决的很好

@icedx NICE, 现在的Python3是越来越有用的理由了, 把手头Python27的项目做完之后, 以后都常使用3了
