Hi all
this has been bugging me for a long time and I do not seem to be able to
understand what to do. I always have problems when dealing input text that
contains umlauts. Consider the following:
In [1]: import urllib
In [2]: f = urllib.urlopen("http://www.google.de/ig/api?weather=Muenchen";)
In [3]: xml = f.read()
In [4]: f.close()
In [5]: print xml
------> print(xml)

As you can see the umlauts in the XML are not displayed properly. When I want
to process this text (for example with xml.sax), I get error messages because
the parses can't read this.
I've tried to read up on this and there is a lot of information on the web, but
nothing seems to work for me. For example setting the coding to UTF like this:
# -*- coding: utf-8 -*- or using the decode() string method.
I always have this kind of problem when input contains umlauts, not just in
this case. My locale (on Ubuntu) is en_GB.UTF-8.

try this?
# vim: set fencoding=utf-8:
import urllib
import xml.sax as sax, xml.sax.handler as handler
f = urllib.urlopen("http://www.google.de/ig/api?weather=Muenchen";)
xml = f.read()
xml = xml.decode("cp1252")
f.close()
class my_handler(handler.ContentHandler):
def startElement(self, name, attrs):
print "begin:", name, attrs
def endElement(self, name):
print "end:", name
sax.parseString(xml, my_handler())
This is wrong. XML is a *byte*-based format, which explicitly states
encodings. So decoding a byte-string to a unicode-object and then
passing it to a parser is not working in the very moment you have data that
- is outside your default-system-encoding (ususally ascii)
- the system-encoding and the declared decoding differ
Besides, I don't see where the whole SAX-stuff is supposed to do
anything the direct print and the decode() don't do - smells like
cargo-cult to me.
