【求助】python xml文件读取和转换问题
#将GB2312格式转为UTF-8格式
f = codecs.open('e:\TestResult.xml', "rb", "gb2312")
text = f.read().encode("utf-8")
f.close
f = open(options.TestResultFile, "wb")
f.write(text)
f.close()
提示 File "E:\TOOLS\ICP\ICP-23\cruisecontrol\userData\groups\group01\projects\R12ProductTest\script\pyt
hon_script\StaticResult.py", line 29, in main
text = f.read().encode("utf-8")
File "C:\Python25\lib\codecs.py", line 606, in read
return self.reader.read(size)
UnicodeDecodeError: 'gb2312' codec can't decode bytes in position 55-56: illegal multibyte sequence
是f.read()出了问题，因为。encode("utf-8") 去掉仍然是该现象。
不知道我这里读取有何问题？
这是成熟的产品代码，已经有别人在使用。而且我使用他们同样的文件来操作，以及同样的python版本（2.5）也是这样的问题，好奇怪！
[解决办法]
试试改gbk范围比gb2312大。codecs好像是python基本模块，真的有问题的话大家的都一样要错的吧...
下面是wingdows下官版shell里一个简单测试，gbk能而gb2312不能：
Python 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> s = '\x81\x40'
>>> print s
丂
>>> s.decode('gbk')
u'\u4e02'
>>> s.decode('gb2312')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'gb2312' codec can't decode bytes in position 0-1: illegal m
ultibyte sequence
>>>

我是这样转的
- Python code
def open(self, xmlfile): returnStatus = False try: data = self._openAnything(xmlfile) if data: data = data.decode('GBK').encode('UTF-8') data = data.replace('gb2312', 'utf-8') data = data.replace('GB2312', 'utf-8') self.__xmldom = xml.dom.minidom.parseString(data) self.__isOpenFile = True returnStatus = True except Exception, e: print Exception, e returnStatus = False return returnStatus
