libgexf python and unicode

[paul]

Hi dear gephi community,

My first post here so I start by a big Thank you to the all community of people around gephi and libgexf, you work rocks !

So I am starting to use libgexf through th python bindings.

I do have some nodes label which are unicode strings containing french accents.
When I try a

Code: Select all

data.setNodeLabel("id",myUnicodeString)

I got this error :

Traceback (most recent call last):
Traceback (most recent call last):
File "sqlToGexf.py", line 61, in ?
data.setNodeLabel(str(idNode),topic)
File "libgexf.py", line 776, in setNodeLabel
def setNodeLabel(self, *args): return _libgexf.Data_setNodeLabel(self, *args)
TypeError: in method 'Data_setNodeLabel', argument 3 of type 'std::string const &'

Ok now if I do this :

Code: Select all

data.setLabel("id",str(myUnicodeString))

it works till topic contains a unicode char (i.e. contains a french accent)

Traceback (most recent call last):
File "sqlToGexf.py", line 61, in ?
data.setNodeLabel(str(idNode),str(topic))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 2: ordinal not in range(128)

Of course I could get rid of accents but well I first want to be sure there's no way to keep my dear french accents ?

thank for your help

Paul

ps: I don't understand the difference between data.setLabel() and data.setNodeLabel()
the first one doesn't accept id, string as parameters... ?

ok I found the way thanks to this very good link http://diveintopython.org/xml_processing/unicode.html

Code: Select all

data.setNodeLabel("id",myUnicodeString.encode("utf-8"))

Hi Paul,

I don't see any data.setLabel() function (http://gexf.net/lib/api/functions_func.html#index_s). Where did you find it?
