I also ran into this recently, but just worked around it by using a QBuffer
to collect data for use in a QByteArray. Since the QXmlQuery writes its
results encoded as UTF-8, you can then create a QString from the QByteArray.
array = QByteArray()
buf = QBuffer(array)
buf.open(QIODevice.WriteOnly)
if query.isValid():
if query.evaluateTo(buf):
results = QString.fromUtf8(array)
print results
buf.close()
