我有一个名为data.xml的本地 xml 文件。我已经使用PullParser对其进行了解析。解析后logcat输出为：

我已经使用这种方法来解析 XML 文件：

//local XML
         private String getEventsFromAnXML(Activity activity)
                    throws XmlPullParserException, IOException
                    {
                     StringBuffer stringBuffer = new StringBuffer();
                     Resources res = activity.getResources();
                     XmlResourceParser xpp = res.getXml(R.xml.data);
                     xpp.next();

                     int eventType = xpp.getEventType();
                     while (eventType != XmlPullParser.END_DOCUMENT)
                     {
                      if(eventType == XmlPullParser.START_DOCUMENT)
                      {
                      // stringBuffer.append("--- Start XML ---");
                       Log.i("Start:", "--- Start XML ---");
                      }
                      else if(eventType == XmlPullParser.START_TAG)
                      {
                       stringBuffer.append("\nSTART_TAG: "+xpp.getName());

                       Log.i("Start:", stringBuffer.toString());
                      }
                      else if(eventType == XmlPullParser.END_TAG)
                      {
                       stringBuffer.append("\nEND_TAG: "+xpp.getName());
                       Log.i("End:", stringBuffer.toString());
                      }
                      else if(eventType == XmlPullParser.TEXT)
                      {
                       stringBuffer.append("\nTEXT: "+xpp.getText());
                       Log.i("Text:", stringBuffer.toString());
                      }
                      eventType = xpp.next();
                     }
                     stringBuffer.append("\n--- End XML ---");
                     return stringBuffer.toString();
                    }

但是，我希望输出是这样的：

我哪里错了？如果我可以将 xml 数据存储在 String 变量中，那将是最好的。

尝试这个 ：

            int eventType = parser.getEventType();

            done = false;

            while (eventType != XmlPullParser.END_DOCUMENT && !done) {
                String name = null;
                switch (eventType) {
                case XmlPullParser.START_DOCUMENT:

                    break;

                case XmlPullParser.START_TAG:
                    name = parser.getName();


                    if (name.equalsIgnoreCase("mchoice")) {

                        // Initialize your list

                    } else if (list!= null) {

                        if (name.equals(question)) {

                            System.out.println("question : " + parser
                                    .nextText());

                        }

                        else if (name.equalsIgnoreCase("id")) {

                            System.out.println("id : " + parser
                                    .nextText());

                        }

                        else if (name.equalsIgnoreCase("option1")) {

                            System.out.println("option 1 : " + parser
                                    .nextText());

                        }

                        else if (name.equalsIgnoreCase("option2")) {

                            System.out.println("option 2 : " + parser
                                    .nextText());

                        }
