httpclient请求去掉返回结果string中的多余转义字符

public String doGet()
    {
        String uriAPI = "http://XXXXX?str=I+am+get+String";
        String result= "";
//      HttpGet httpRequst = new HttpGet(URI uri);
//      HttpGet httpRequst = new HttpGet(String uri);
//      创建HttpGet或HttpPost对象，将要请求的URL通过构造方法传入HttpGet或HttpPost对象。
        HttpGet httpRequst = new HttpGet(uriAPI);

//      new DefaultHttpClient().execute(HttpUriRequst requst);
        try {
   //使用DefaultHttpClient类的execute方法发送HTTP GET请求，并返回HttpResponse对象。
            HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequst);//其中HttpGet是HttpUriRequst的子类
            if(httpResponse.getStatusLine().getStatusCode() == 200)
            {
                HttpEntity httpEntity = httpResponse.getEntity();
                result = EntityUtils.toString(httpEntity);//取出应答字符串
            // 一般来说都要删除多余的字符
                result.replaceAll("
", "");//去掉返回结果中的"
"字符，否则会在结果字符串后面显示一个小方格
            }
                   else
                        httpRequst.abort();
           } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            result = e.getMessage().toString();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            result = e.getMessage().toString();
        }
        return result;
    }
