    try //database structure
    {

        Element username = doc.createElement("username");
        username.appendChild(doc.createTextNode("testusername"));
        rootElement.appendChild(username);

        Element lat = doc.createElement("latitude");
        lat.appendChild(doc.createTextNode(String.valueOf(latitude)));
        rootElement.appendChild(lat);
        //longitude
        Element longi = doc.createElement("longitude");
        longi.appendChild(doc.createTextNode(String.valueOf(longitude)));
        rootElement.appendChild(longi);

        //caption text …
