[Qgis-user] Open Metadata and Show Specific Information

[Suryo Miles]

I try make plugin to open and read metadata (.xml) and show information
inside metadata like map scale, map fiture and bounding box and auto fill
it to QLineEdit

This code i use to open metadata


cariButton = self.ui.btnCari
        QtCore.QObject.connect(cariButton, QtCore.SIGNAL('clicked()'),self.cari)

    def cari(self, event=None):

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

        self.ui.lineFile.setText(filename)

        #panggil isi data
        self.isiDataFile(filename)

    def isiDataFile(self, nmfile):
        #buka dengan open mode baca
        teksFile = open(nmfile, 'r').read()

        self.ui.textFile.setText(teksFile)

but metadata have a complicated structure, like the line that have
information about scale

<gmd:scaleDenominator><gmd:MD_RepresentativeFraction><gmd:denominator>**<gco:Integer>100000</gco:Interger>**</gmd:scaleDenominator></gmd:MD_RepresentativeFraction></gmd:denominator>

it is possible to just take scale number (100000) and auto fill it in
QLineEdit when metadata has opened?
