XMLHttpRequest() not working properly with XmlListModel

  • I am using XMLHttpRequest() to get xml data from a webpage and use it in a XmlListModel. The problem that I got seems to be that XmlListModel only gets a small portion of the data as .responseText using @console.log(httpReq.responseText)@ only gives me a partial xml data around 20% of what's inside the xml.

    The other issue is that XmlListModel is always behind one call, when I first call the function it says fullscreen is undefined but when I call it again it's fine. BUT this function needs to be called ever 1 second to get updated data as the xml file is always changing but only ever second call gives me right data.

    The function looks like this:

    id: xmlModel
    query: "/root"
    XmlRole{ name: "fullscreen"; query: "fullscreen/string()"}
    XmlRole{ name: "volume"; query: "volume/string()"}
    XmlRole{ name: "random"; query: "random/string()"}
    XmlRole{ name: "state"; query: "state/string()"}
    XmlRole{ name: "loop"; query: "loop/string()"}
    XmlRole{ name: "repeat"; query: "repeat/string()"}

    function getVLCstatus()
    var httpReq = new XMLHttpRequest()
    var url = "http://" + ip + ":" + port + "/requests/status.xml";

    httpReq.open("GET", url, true);
    // Send the proper header information along with the request
    httpReq.setRequestHeader("Authorization", "Basic " + Qt.btoa(username + ":" + password));
    httpReq.setRequestHeader('Content-Type',  'text/xml');
    httpReq.onreadystatechange = function()
        if(httpReq.readyState === XMLHttpRequest.DONE)
            if(httpReq.status == 200)
                xmlModel.xml = httpReq.responseText


    Am I doing something wrong?
