XMLListModel Related Questions

Hello

A while ago i needed to create a program which uses xml files. But i have never worked with neither xml nor json files. So i don't have much of an idea about them, which is why i decided to download a few xml files from the internet and work with them.

Anyways here are my questions regarding xml files

I tried loading which was very succesfull, but i couldn't read a single value from it although playing around with it for while. How can i read the values and display them on screen.
Is it possible to write values after they are changed by the user?
Can i group these together with, like one-key-one-value. So i can have them better controlled?

Thanks in advance for any help.

Here is my code and xml file:

import QtQuick 2.7
import QtQuick.Window 2.2
import QtQuick.XmlListModel 2.0

Window {
    visible: true
    width: 1200
    height: 600
    title: qsTr("Hello World")

    MainForm {
        anchors.fill: parent
        color: "#141414"

        ListView {
            spacing: 5

            model: xmlModPlist

            delegate: Text {
                color: "#ffffff"
                text: key
                font.family: "Calibri"
                font.pointSize: 16
                verticalAlignment: Text.AlignVCenter
                horizontalAlignment: Text.AlignHCenter
                antialiasing: true
            }
        }

        XmlListModel {
            id: xmlModPlist
            source: "qrc:/Res/particle.plist"
            query: "/plist/dic"

            XmlRole {name: "key"; query: "key/string()"}
        }
    }
}

Okay, so i learned a few things.

It seems writing to xml files using QML is not possible, but by using C++ side of things it can be done. So my questions are now invalid it seems.
