thanks for you fast reply.
I tried it again, and now it works, without me knowing why :( -
The same code, the same input file, but I must have changed something
But anyway, that's the way I read in the data:
from xml.dom import Node
from xml.dom import ext
from xml.dom.ext.reader import PyExpat
from xml import xpath
from xml.xpath import Util
from Ft.Lib.pDomlette import PyExpatReader
from StringIO import StringIO
self.reader = PyExpatReader()
self.doc = self.reader.fromUri(fileName)
self.result = xpath.Evaluate('//entry', contextNode=self.doc)
To be honest, I just thought that strings would just be unicode strings. I will
do some reading on unicode objects.
