I'm having trouble using elementtree with an XML file that has some
gbk-encoded text. (I can't read Chinese, so I'm taking their word for
it that it's gbk-encoded.) I always have trouble with encodings, so I'm
sure I'm just screwing something simple up. Can anyone help me?
Here's the interactive session. Sorry it's a little verbose, but I
figured it would be better to include too much than not enough. I
basically expected et.ElementTree(file=...) to fail since no encoding
was specified, but I don't know what I'm doing wrong when I use
codecs.open(...)
Thanks in advance for the help! import elementtree.ElementTree as et
import codecs
et.ElementTree(file=filename)

The first and most important lesson to learn here is that well-formed
XML must contain a xml-header that specifies the used encoding. This has
two consequences for you:
1) all xml-parsers expect byte-strings, as they have to first read the
header to know what encoding awaits them. So no use reading the xml-file
with a codec - even if it is the right one. It will get converted back
to a string when fed to the parser, with the default codec being used -
resulting in the well-known unicode error.
2) your xml is _not_ well-formed, as it doesn't contain a xml-header!
You need ask these guys to deliver the xml with header. Of course for
now it is ok to just prepend the text with something like <?xml
version="1.0" encoding="gbk"?>. But I'd still request them to deliver it
with that header - otherwise it is _not_ XML, but just something that
happens to look similar and doesn't guarantee to be well-formed and thus
can be safely fed to a parser.

Thanks, that's very helpful. I'll definitely harrass the people
producing these files to make sure they put encoding declarations in them.

absolutely!
pyexpat has only limited support for non-standard encodings; the core
expat library only supports UTF-8, UTF-16, US-ASCII, and ISO-8859-1,
and the Python glue layer then adds support for all byte-to-byte en-
codings support by Python on top of that.
if you're using any other encoding, you need to recode the file on the
way in (just decoding to Unicode doesn't work, since the parser expects
an encoded byte stream). the approach shown on this page should work http://effbot.org/zone/celementtree-encoding.htm
except that it uses the new XMLParser interface which isn't available in
ET 1.2.6, and the corresponding XMLTreeBuilder interface in ET doesn't
support the encoding override argument...
the easiest way to fix this is to modify the file header on the way in; if
the file has an <?xml encoding?> header, rip out the header and recode
from that encoding to utf-8 while parsing.

good advice, but note that an envelope (e.g a HTTP request or response
body) may override the encoding in the XML file itself. if this arrives in a
MIME message with the proper charset information, it's perfectly okay to
leave out the encoding from the file.

It might be practical - still, a xml parser _should_ puke on you, ans
certainly some will (elemnttree not being one of those, I know :))
So even if it goes over the wire headerless, you should be prepending it
when dealing with teh data later.

Interesting.

no, the parser must not to choke on a file for which the encoding has been
overridden.
for example, the HTTP standard allows the transport layer to recode text/* re-
sources as long as it updates the charset properly, so if you e.g send an XML
document as text/xml and charset=iso-8859-1, the transport layer can recode
that to charset=utf-8, *without* rewriting the XML header.

I have to correct myself: I was under the impression that XML _has_ to
contain an XMLDecl (which is the header, possibly with encoding) to be
well-formed.
Interestingly enough, that has not to be the case. A document can very well
be well-formed without a header. The constraints for well-formedness are
scattered throughout the spec, so I'm not sure what they say about the used
encoding in absence of a header.
I am certain though that I've met parsers which weren't able to digest xml
without XMLDecl - which formed my impression. But then, that wasn't
correct.
Boy, that XML-stuff is always full of surprises - even after so many years
dealing with it..

if there's no header, and no external override, the document must use either
UTF-8 or UTF-16, and for UTF-16, a leading byte order mark must be present
(ASCII is of course a subset of UTF-8, but e.g. ISO-8859-1 isn't).
reading
http://www.w3.org/TR/2004/REC-xml-20.../#sec-guessing
may also help (at least if you read between the lines).

Thanks (to both Fredrik and Just). You stare at XML too long and you
start to miss the obvious things too. =)
Everything works great now: text = open(filename).read()
text = re.sub(r'<S ID=(\w+)', r'<S ID="\1"', text)
text = text.decode('gbk').encode('utf-8')
et.fromstring(text)
