Need help to parse Xml file

[modjo756]

I have already open a topic here on another problem (solved) about a xml file that i need to parse. Now i'm trying to get the data and organize it.
In this file i need to query the Item Value and it's children. To do that i use this code :

    XmlListModel {
        id: xmlModelValue
        source: Qt.resolvedUrl(path)
        query: "/Product/CommandClass/Value"
        namespaceDeclarations:"declare default element namespace 'http://code.google.com/p/open-zwave/';"
        roles: [
            XmlRole { name: "type"; query: "@type/string()" },
            XmlRole { name: "genre"; query: "@genre/string()" },
            XmlRole { name: "instance"; query: "@instance/number()" },
            XmlRole { name: "index"; query: "@index/number()" },
            XmlRole { name: "label"; query: "@label/string()" },
            XmlRole { name: "value"; query: "@value/number()" },
            XmlRole { name: "min"; query: "@min/number()" },
            XmlRole { name: "max"; query: "@max/number()" },
            XmlRole { name: "size"; query: "@size/number()" },
            XmlRole { name: "help"; query: "Help/string()"}

        ]
        onStatusChanged: status === XmlListModel.Ready ? console.log("nbr instance value : "+xmlModelValue.count):console.log("loading data ...")
    }

To display the the data i use a ListView like that :

 ListView {
        anchors.fill: parent
        anchors.margins: 4
        model: xmlModelValue
        header:
            Rectangle{
            implicitHeight: childrenRect.height+5
            implicitWidth: childrenRect.width+10
            anchors.horizontalCenter : parent.horizontalCenter
            color: "transparent"
            Text {
                horizontalAlignment: Qt.AlignHCenter
                text: "Zwave configuration for : "+path
                color:"white"
                font.pixelSize: 32
            }
        }
        delegate:
            RowLayout{
            anchors.left: parent.left
            anchors.right: parent.right
            Rectangle{
                Layout.preferredHeight: childrenRect.height+5
                //                implicitWidth: parent.width
                Layout.fillWidth: true
                color: "transparent"
                border.color: "gray"
                border.width: 1
                radius: 3
                RowLayout{
                    Text {
                        text: model.label
                        color:"white"
                        font.pixelSize: 20
                    }

                    Text {
                        text: "?"
                        color:"white"
                        font.pixelSize: 30
                        MouseArea{
                            anchors.fill: parent
                            onClicked: popup.open()
                        }
                    }
                }
            }
            Popup {
                     id: popup
                     x: main.width/2
                     width: 400
                     height: childrenRect.height
                     modal: true
                     focus: true
                     closePolicy: Popup.CloseOnEscape | Popup.CloseOnPressOutsideParent
                     ColumnLayout{
                     Text {
                         anchors.fill: parent
                         text: model.help
                         wrapMode: Text.WordWrap
                     }
                     Button{
                         text: "Close"
                         onClicked: popup.close()
                     }
                     }
                 }
        }
    }

This work fine. But i also need to query the item "Item" that is inside Value :

<Value type="list" genre="config" instance="1" index="34" label="Reaction to alarms" value="63" min="1" max="63" size="1">
      <Help>Type of transmitted control frame for association group 1, activated via input IN1. The parameter allows to specify the type of alarm frame or to force transmission of control commands (BASIC_SET)</Help>
      <Item label="ALARM GENERIC" value="1" />
      <Item label="ALARM SMOKE" value="2" />
      <Item label="ALARM CO" value="4" />
      <Item label="ALARM CO2" value="8" />
      <Item label="ALARM HEAT" value="16" />
      <Item label="ALARM WATER" value="32" />
      <Item label="ALARM ALL" value="63" />
    </Value>

I can't get the Item role like this :

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

Do you known how i can get it ? Do i need to create another XmlListModel ? If i did that i can't determine where to place it (in the good section) in my listView ...
