saving data to a file in metro style apps

Question

Hi, 

  I have code regarding writing data to an xml file .

 

 

addTask: function (task) {  

            var packaged = Windows.ApplicationModel.Package.current;
            var installedLocation = packaged.installedLocation;

            installedLocation.createFileAsync("\data\\mydata.xml", Windows.Storage.CreationCollisionOption.replaceExisting).then(function (dataFile) {

                xml.XmlDocument.loadFromFileAsync(dataFile).then(function (xmldoc) {

                    var taskNode = xmldoc.createElement("Task");
                    var parentnode = xmldoc.selectSingleNode("PM");
                    //===insertion goes here ==============

                    taskNode.appendChild(xmldoc.createElement("TaskID")).innerText = new Date().getTime();
                    taskNode.appendChild(xmldoc.createElement("Title")).innerText = task.title;
                    parentnode.appendChild(taskNode);

                    xmldoc.saveToFileAsync(dataFile).done(function () {});

                   
                });

            });

            return true;
        }
