    Default Need enlightenment working with xmllistmodel

    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. Just to be sure I also tested with another and more simple xml file - https://www.w3schools.com/xml/books.xml - and all went fine.

    A portion of the "problematic" XML file:
    Qt Code:
    1. <?xml version="1.0"?>

    My QML code:
    Qt Code:
    1. import QtQuick 2.9
    2. import QtQuick.Window 2.2
    3. import QtQuick.XmlListModel 2.0
    4.  
    5. Window {
    6. visible: true
    7. width: 640
    8. height: 480
    9. title: qsTr("Hello World")
    10.  
    11. XmlListModel {
    12. id: xmlModel
    13. source: "qrc:/xml/dataFULL.xml"
    14. query: "/Envelope/Body/RecebeResponse/RecebeResult/Pedido/Actualizacoes/Actualizacao/Postos/Existentes/Posto"
    15.  
    16.  
    17. namespaceDeclarations: "declare default element namespace 'http://schemas.xmlsoap.org/soap/envelope/';"+
    18. "declare namespace u='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd';"+
    19. "declare namespace o='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd';"+
    20. "declare namespace xsi='http://www.w3.org/2001/XMLSchema-instance';"+
    21. "declare namespace xsd='http://www.w3.org/2001/XMLSchema';"
    22.  
    23.  
    24. XmlRole { name: "Nome"; query: "Nome/string()"}
    25.  
    26. }
    27.  
    28. ListView{
    29. id: list
    30. width: 300; height: 300
    31. model: xmlModel
    32. delegate: Text { text: Nome }
    33. }
    34. }

    Hope someone can give me a hand figuring this out!

    ... Since I couldn't use xmllistmodel I have changed my approach.
    Created a class derived from QAbstractItemModel applied this model to QML.

    For now it works.
