I am trying to build a GUI for navigating through a large XML database on a Mac running OS
10.7, Python 3.3, PyQt 4. I want to get a list of the text in all of the nodes
called<Orth> and put them into a QListWidget called "hLexNav". To do this, I
wrote the following bit of code (this isn't the whole thing, just the parts that are supposed
to add items to the listbox):
import sys
from PyQt4 import QtCore, QtGui
from xml.dom import minidom
import xml.etree.ElementTree as etree
from fieldbookGui import Ui_Fieldbook
import images
import btnCmds
class MyForm(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_Fieldbook()
self.ui.setupUi(self)
xmltree = etree.parse('BabyDb.xml')
root = xmltree.getroot()
for child in root:
self.ui.hLexNav.addItem(child.findtext('Orth'))
The first 25 items that are returned by child.findtext('Orth') are:
['a:', 'a:cháj', 'a:chulá:', "a:hé:xtu'", 'a:ho:tán', 'a:kús', "a:li:ma'htín", 'a:li:stá:n', 'a:má', "a:ma'ha:'pi'tzí'n", 'a:mixtzayán', 'a:nanú:', 'a:tú:n',
'a:tzá:', "a:tzemá'j", 'a:xí:lh', 'a:xtúm', 'a:xú:x', "a:'hála'", "a:'j", "a:'jmá", "a:'jnanú:", "a:'jtzá:",
"a:'jtzananú:", "a:'kní:"]
In the QListWidget created by this code, I see only items corresponding to those elements that do
not contain accented vowels (here, those that don't contain "á", "ú", etc.);
items that correpsond to strings with accented vowels are left empty. Further experimentation with
addItem( ), addItems(), and insertItem( ) show that any string that contains an non-ASCII character
results in an empty Item being inserted into the QListWidget.
Any ideas about what is going on would be appreciated.
Are you 100 % sure that unicode is handled properly while reading the
xml? I never had problems with unicode and PyQt but I strictly using
unicode strings only in my apps.
This for example works for me (Python 2.7):
# -*- coding: utf-8 -*-
if __name__ == "__main__":
import sys
from PyQt4.QtGui import *
app = QApplication(sys.argv)
list_widget = QListWidget()
list_widget.addItem(u"ÄÜ^° là lÁ")
list_widget.show()
app.exec_()
