android - 从 xml webservice 解析只包含一个字符串

Question

我遇到了下一个问题，我有一个 xml 网络服务只包含一个字符串示例：您输入了 Invalis 数据，我想将此字符串读入我的应用程序。我的代码运行良好，但突然开始返回一个 html 代码，而不是我想要的字符串 :( 这是我的代码：

try {

    String xx;

    DefaultHttpClient httpClient = new DefaultHttpClient();
;


    HttpGet httpPost = new HttpGet(urlString);

    HttpResponse httpResponse = httpClient.execute(httpPost);
    HttpEntity httpEntity = httpResponse.getEntity();
    inputStream = httpEntity.getContent();

    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"),
            8);
    StringBuilder stringBuilder = new StringBuilder();
    String line = null;
    if ((line = reader.readLine()) != null) {
        stringBuilder.append(line + "\n");
        xx = stringBuilder.toString();
        }



    inputStream.close();


    }
    catch (UnsupportedEncodingException e) {
        System.err.print("UnsupportedEncodingException: " + e);
    }
    catch (ClientProtocolException e) {
        System.err.print("ClientProtocolException: " + e);
    }
    catch (IOException e) {
        System.err.print("IOException: " + e);
    }

如果有人可以提供帮助，请！
