[Qgis-user] argument 1 has unexpected type error when parse xml with ElementTree

[Suryo Miles]

I try to make plugin in QGIS Dufour to open and read xml metadata and then
to show some information in metadata i try to parse it with ElementTree and
then show it in QLineEdit, this code i use to open metadata and parse
metadata :

from PyQt4 import QtCore, QtGui
from ui_testparse import Ui_testparse
import xml.etree.ElementTree as ETree
# create the dialog for zoom to point


class testparseDialog(QtGui.QDialog):
    def __init__(self):
        QtGui.QDialog.__init__(self)
        # Set up the user interface from Designer.
        self.ui = Ui_testparse()
        self.ui.setupUi(self)

        opendata = self.ui.btnCari
        QtCore.QObject.connect(opendata,
QtCore.SIGNAL('clicked()'),self.openxml)

    def openxml(self, event=None):

        #open dialog
        openfile = QtGui.QFileDialog.getOpenFileName(self, 'Open File', '*.xml')

        self.ui.lineLokasi.setText(openfile)

        #call XML data
        self.isiData(openfile)

    def isiData(self, nmsatu):
        #open teks with read mode
        openteks = open(nmsatu, 'r').read()

        self.ui.textXml.setText(openteks)

        #Parse XML from Above
        self.parsenow(openteks)

    def parsenow(self, parse):
        element = ETree.fromstring(parse)
        xml_obj = ETree.ElementTree(element)
        for title_obj in
xml_obj.findall('.//{http://www.isotc211.org/2005/gmd}dateStamp/'
             '{http://www.isotc211.org/2005/gco}Date'):
            print element
        self.ui.lineSkala.setText(element)

however when i try to run it, it give me a error message, the error message say:

Traceback (most recent call last):
  File "C:\Users\Mr.Pakde/.qgis2/python/plugins\testparse\testparsedialog.py",
line 47, in openxml
    self.isiData(openfile)
  File "C:\Users\Mr.Pakde/.qgis2/python/plugins\testparse\testparsedialog.py",
line 56, in isiData
    self.parsenow(openteks)
  File "C:\Users\Mr.Pakde/.qgis2/python/plugins\testparse\testparsedialog.py",
line 64, in parsenow
    self.ui.lineSkala.setText(element)
TypeError: QLineEdit.setText(QString): argument 1 has unexpected type 'Element'

Python version:
2.7.4 (default, Apr  6 2013, 19:54:46) [MSC v.1500 32 bit (Intel)]

and xml file i want to parse look like this :

<gmd:dateStamp>
      <gco:Date>2013-12-12</gco:Date>
