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:
XmlListModel{
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
console.log(xmlModel.get(0).fullscreen)
}
}
}
httpReq.send();
}
Am I doing something wrong?
