    Hello everyone,

    I hope this is the right place to ask for help in the following matter, if not just point me in the right direction.
    I'm trying to use XmlListModel with a xml file I got from a server. I think the problem may be with namespace declarations but I have tried many combinations without success. To be sure I could use this qml type, I tried this with another xml file - https://www.w3schools.com/xml/books.xml - all went good!

    Here's a portion of the "problematic" xml file:

    <?xml version="1.0"?>
    <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
    	<s:Header>
    		<o:Security xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" s:mustUnderstand="1">

    			</u:Timestamp>
    		</o:Security>
    	</s:Header>
    	<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

    Here's my qml code:

    import QtQuick 2.9
    import QtQuick.Window 2.2
    import QtQuick.XmlListModel 2.0
    
    Window {
        visible: true
        width: 640
        height: 480
        title: qsTr("Hello World")
    
        XmlListModel {
            id: xmlModel
    		source: "qrc:/xml/dataFULL.xml"
            query: "/Envelope/Body/RecebeResponse/RecebeResult/Pedido/Actualizacoes/Actualizacao/Postos/Existentes/Posto"
    
    
            namespaceDeclarations: "declare default element namespace 'http://schemas.xmlsoap.org/soap/envelope/';"+
                                   "declare namespace u='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd';"+
                                   "declare namespace o='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd';"+
                                   "declare namespace xsi='http://www.w3.org/2001/XMLSchema-instance';"+
                                   "declare namespace xsd='http://www.w3.org/2001/XMLSchema';"
    
    
            XmlRole { name: "Nome"; query: "Nome/string()"}
    
        }
    
        ListView{
            id: list
            width: 300; height: 300
            model: xmlModel
            delegate: Text { text: Nome }
        }
    }
    

    With this code the "Text" in the ListView doesn't show anything.
    I'm think this model have some error but I don't know how to retrieve the error to fix it.

    Hope someone can give me a hand figuring this out!

      ... Since I couldn't use xmllistmodel I changed my approach.
      Created a class derived from QAbstractItemModel and applied this model to QML.
      Don't know if this is the best way but for now it works.
