elementtree w/utf8

[Tim Arnold]

Hi, I'm getting the by-now-familiar error:
return codecs.charmap_ decode(input,er rors,decoding_m ap)
UnicodeEncodeEr ror: 'ascii' codec can't encode character u'\xa9' in position
4615: ordinal not in range(128)

the html file I'm working with is in utf-8, I open it with codecs, try to
feed it to TidyHTMLTreeBui lder, but no luck. Here's my code:
from elementtree import ElementTree as ET
from elementtidy import TidyHTMLTreeBui lder

fd = codecs.open(htm file,encoding=' utf-8')
tidyTree =
TidyHTMLTreeBui lder.TidyHTMLTr eeBuilder(encod ing='utf-8')
tidyTree.feed(f d.read())
self.tree = tidyTree.close( )
fd.close()

what am I doing wrong? Thanks in advance.

On a related note, I have another question--where/how can I get the
cElementTree.py module? Sorry for something so basic, but I tried installing
cElementTree, but while I could compile with setup.py build, I didn't end up
with a cElementTree.py file anywhere. The directory structure on my system
(HPux, but no root access) doesn't work well with setup.py install.

thanks,

You feed decoded data to `TidyHTMLTreeBu ilder`. As the `encoding`
argument suggests this class wants bytes not unicode. Decoding twice
doesn't work.

Being to clever for your own good.. sorry to say so. But
TidyHTMLTreeBui lder takes the encoding for a reason: it expects a
byte-string that it will decode itself.

But you decode first, creating a unicode-object. When feeding that to
the string-expecting feed-method, python attempts a conversion to a
byte-string using the default-encoding.

Not using codecs but a file instead should do the trick.

well now that you say it, it seems so obvious...
some day I will get the hang of this encode/decode stuff. When I read about
it, I'm fine, it makes sense, etc. maybe even a little boring. And then I
write stuff like the above!

Thanks to you and Diez for straightening me out.

I had the same question a while ago .... and the answer is ElementTree
is now
part of the standard library.

That's because it compiles into a binary extension module, not a plain Python
module (mind the 'c' in its name, which stands for the C language here).

I don't know what the standard library extension is under HP-UX, but look a
little closer at the files that weren't there before, you'll find it.
Depending on what you did to build it, it might also end up in the "build"
directory or as an installable package in the "dist" directory.

The directory structure on my system
(HPux, but no root access) doesn't work well with setup.py install.

That shouldn't be a problem as long as you keep the binary in your PYTHONPATH.

As suggested before, if you have Python 2.5, you don't even need to install it
yourself.

very nice--thanks. I saw the cElementTree.sl file, but didn't realize it
would work as-is.
