XmlPullParserException：解析xml时出现意外的令牌错误

Question

我发现很多人有这个问题，但找不到任何答案。我从url读取xml，它是有效的，包含xml头声明。 我做错了什么？

这是我的代码：

    String data = "";
    InputStream iStream = null;
    URL url = new URL(strUrl);
    HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
    urlConnection.connect();
    iStream = urlConnection.getInputStream();
    BufferedReader br = new BufferedReader(new InputStreamReader(iStream));
    StringBuffer sb  = new StringBuffer();
    String line = "";
    while( ( line = br.readLine())  != null){
            sb.append(line);
    }
    data = sb.toString();
     StringReader reader = new StringReader(data);
   XmlPullParser parser = Xml.newPullParser();
   parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);
   parser.setInput(reader);
   parser.nextTag();

这是我的xml：

   <organizations>
   <organization name="ps" private="true"   flag="http://wptrafficanalyzer.in/p/demo1/india.png"><country>US</country><city city="New York" />
    <OrganizationID >12</OrganizationID>
    </organization>
   </organizations>
