Encoding issues with python's etree.tostring
提问by smock
I'm using python 2.6.2's xml.etree.cElementTree to create an xml document:
我正在使用 python 2.6.2 的 xml.etree.cElementTree 创建一个 xml 文档：
import xml.etree.cElementTree as etree
elem = etree.Element('tag')
elem.text = (u"Würth Elektronik Midcom").encode('utf-8')
xml = etree.tostring(elem,encoding='UTF-8')
At the end of the day, xml looks like:
在一天结束时，xml 看起来像：
<?xml version='1.0' encoding='UTF-8'?>
<tag>Würth Elektronik Midcom</tag>
It looks like tostring ignored the encoding parameter and encoded 'ü' into some other character encoding ('ü' is a valid utf-8 encoding, I'm fairly sure).
看起来 tostring 忽略了编码参数并将 'ü' 编码为其他一些字符编码（'ü' 是有效的 utf-8 编码，我很确定）。
Any advice as to what I'm doing wrong would be greatly appreciated.
任何关于我做错了什么的建议将不胜感激。

You're encoding the text twice. Try this:
您对文本进行了两次编码。试试这个：
import xml.etree.cElementTree as etree
elem = etree.Element('tag')
elem.text = u"Würth Elektronik Midcom"
xml = etree.tostring(elem, encoding='UTF-8')

etree.tostring(elem, encoding=str)
etree.tostring(elem, encoding=str)
will return strbut not binaryin Python 3
将返回str但不在binaryPython 3 中
You can also serialise to a Unicode string without declaration by passing the
unicodefunction as encoding (orstrin Py3), or the name 'unicode'. This changes the return value from a byte string to an unencoded unicode string.
您还可以通过将
unicode函数作为编码（或str在 Py3 中）或名称“unicode”传递来序列化为Unicode 字符串而无需声明。这会将返回值从字节字符串更改为未编码的 unicode 字符串。
