python之Unicode 和 lxml 对象化数据

我收到标准的 UnicodeEncodeError: 'ascii' codec can't encode character u'\xa9' in position 15: ordinal not in range(128)，但我无法得到通常的补救措施。

我尝试将第 72 行更改为 gName = getattr(root, u"name", "").encode('utf-8').strip() 它给了我 AttributeError: no such child: encode 我在第 84 行尝试了 gName.encode('utf-8')，结果相同。

请您参考如下方法:

为什么不尝试以 utf8 格式写入您的文件

OutFile = open(Output_File,'ab', 'utf8') 
OutFile.write(tup) 
OutFile.close()
