解决方案

 公共静态无效getAllXML（字符串URL）抛出XmlPullParserException，IOException异常，{的URISyntaxException  XmlPullParserFactory工厂= XmlPullParserFactory.newInstance（）;  factory.setNamespaceAware（真）;  XmlPullParser解析器= factory.newPullParser（）;  parser.setInput（新的InputStreamReader（getUrlData（URL）））;  XmlUtils.beginDocument（分析器，结果）;  INT EVENTTYPE = parser.getEventType（）;  做{    XmlUtils.nextElement（分析器）;    parser.next（）;    EVENTTYPE = parser.getEventType（）;    如果（EVENTTYPE == XmlPullParser.TEXT）{      Log.d（测试，parser.getText（））;    }  }而（EVENTTYPE = XmlPullParser.END_DOCUMENT！）;}公众的InputStream getUrlData（字符串URL）抛出的URISyntaxException，ClientProtocolException，IOException异常{  DefaultHttpClient客户端=新DefaultHttpClient（）;  HTTPGET方法=新HTTPGET（新的URI（URL））;  HTT presponse解析度= client.execute（法）;  返回res.getEntity（）的getContent（）。}

解决方案

public static void getAllXML(String url) throws 

XmlPullParserException, IOException, URISyntaxException{ 

  XmlPullParserFactory factory = XmlPullParserFactory.newInstance();

  factory.setNamespaceAware(true);

  XmlPullParser parser = factory.newPullParser(); 

  parser.setInput(new InputStreamReader(getUrlData(url)));  

  XmlUtils.beginDocument(parser,"results");

  int eventType = parser.getEventType();

  do{

    XmlUtils.nextElement(parser);

    parser.next();

    eventType = parser.getEventType();

    if(eventType == XmlPullParser.TEXT){

      Log.d("test",parser.getText());

    }

  } while (eventType != XmlPullParser.END_DOCUMENT) ;       

}

public InputStream getUrlData(String url) 

throws URISyntaxException, ClientProtocolException, IOException {

  DefaultHttpClient client = new DefaultHttpClient();

  HttpGet method = new HttpGet(new URI(url));

  HttpResponse res = client.execute(method);

  return  res.getEntity().getContent();

}
