ElementTree and unicode

Question

I have this char in an xml file:

<data>   <products>       <color>fumè</color>   </product> </data> 

I try to generate an instance of ElementTree with the following code:

string_data = open('file.xml') x = ElementTree.fromstring(unicode(string_data.encode('utf-8'))) 

and I get the following error:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xe8' in position 185: ordinal not in range(128) 

(NOTE: The position is not exact, I sampled the xml from a larger one).

How to solve it? Thanks

Answer 1

Might you have stumbled upon this problem while using Requests (HTTP for Humans), response.text decodes the response by default, you can use response.content to get the undecoded data, so ElementTree can decode it itself. Just remember to use the correct encoding.

More info: http://docs.python-requests.org/en/latest/user/quickstart/#response-content

You need to decode utf-8 strings into a unicode object. So

string_data.encode('utf-8') 

should be

string_data.decode('utf-8') 

assuming string_data is actually an utf-8 string.

So to summarize: To get an utf-8 string from a unicode object you encode the unicode (using the utf-8 encoding), and to turn a string to a unicode object you decode the string using the respective encoding.

For more details on the concepts I suggest reading The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (not Python specific).
