Impossible to read an xml file

  • Hi all, like said in the title i have a problem to read this file (zwave configuration file) see under the code that i use :

    Rectangle {
        width: 400; height: 260
        color: "#404040"
        XmlListModel {
            id: xmlModel
            source: Qt.resolvedUrl(""
            query: "/Product"
            XmlRole { name: "title"; query: "@xmlns/string()" }
            Component.onCompleted: {
        ListView {
            anchors.fill: parent
            anchors.margins: 4
            model: xmlModel
            delegate: Text {
                text: model.title
                font.pixelSize: 32

    This code work fine with another xml file (like network.xml in qt installation) but not with it (try also locally). Do you have an idea how i can resolve this ?

    Try changing your query to "xmlns/string()"

    Thanks but why Qt can't read it ?

    well if you compare with an xml that works, with the
    XmlRole { name: "title"; query: "@xmlns/string()" }
    and the structure , you have in this file.

    What is then the difference ?

  • @mrjj
    The problem is that i can't get the value of the xml file. For example, i just want to get the first (for test) item Product. In the file this give :

    <?xml version="1.0" encoding="utf-8"?>
    <Product xmlns=''>

    In my code i want to get the value of xmlns, i proceed like this :

            query: "/Product"
            XmlRole { name: "title"; query: "@xmlns/string()" }

    But this don't give me the result ... and i don't know why !

  • Hi, with a help of my Qt instructor it seems there is a problem with the attribute xmlns in this files. If i replace this one by link (in the xml file) for example it works ! Now i can access to all data in the file ! Perhaps it's necessary to register xmlns with registerMetaType or other ... If someone have an idea ?

  • I known this is an old topic but it can help some people. I have find a solution to read this file. For that just use the namespaceDeclarations property like this :

    namespaceDeclarations:"declare default element namespace '';"

    Now i can parse the file !
