@bahman309 Use @ to get the attributes.

Example:


import QtQuick 2.5
import QtQuick.Controls 1.4
import QtQuick.XmlListModel 2.0

ApplicationWindow {
    visible: true
    width: 640
    height: 480    

    XmlListModel {
        id: xmlModel
        source: "/res/myxml.xml"
        query: "/gallery/album"

        XmlRole { name: "title"; query: "title/string()" }
        // query the img's src (the '@' indicates 'src' is an attribute, not an element)
        XmlRole { name: "img"; query: "img/@src/string()" }
    }

    ListView {
        width: 180; height: 300
        model: xmlModel
        delegate: Text { text: title + ": " + img }
    }
}

@bahman309 Are you getting the title or is it also not working?

I've uploaded my code to GitHub. Use it to check where the error is.

@tarod.net
it is so strange
when i use your code in my project, I get the title but for image just get "undefined",
and when i use your code in a new project, every thing is Ok ...

thank you so much
you are so kind and so expert

@bahman309 And what about your code in a new project?

So, did you solve the problem? I could see more code if you want to or even the whole project. Just tell me where to download it.
