How to check the responses of an HTTP request? - php

Question

I had completed a small Android project(MAP and Location based) 4 months before. Now I am planning to improve the App by upgrading the map API and some code tweaking. As a part of this, I would like to ask that how can I check the response for an HTTP request from the web-server efficiently. My current strategy is:
App will upload the data to PHP server by using HTTP GET method.
The response from server will be in the form of XML tagged format.
I must have to check the corresponding tag for the response from server(use xmlParser example seen in Stack Overflow xml parser).
I think this is little bit annoying for me. Is there any easy method to achieve this process?
Example:
If the user tries to log-in, the credential will be checked in SERVER and successful authentication will be replied as some code: 1 else: 0.
All the HTTP requests are handled as asynctask.

public String login(String login_url,List<NameValuePair> login_parameters_list) throws ClientProtocolException, IOException
{
int response_code = -1;
HttpPost httppost = new HttpPost(post_url);
httppost.setEntity(new UrlEncodedFormEntity(post_parameters_list));
HttpResponse response = httpclient.execute(httppost);
// coockie management
httpclient.getCookieStore().getCookies().get(0).getName();
response_code = response.getStatusLine().getStatusCode();
if(response_code == 999 || response_code == HttpStatus.SC_INTERNAL_SERVER_ERROR)
{
Log.e("HttpResponse", "Internal Server");
}
else if(response_code == -1 )
{
Log.e("HttpResponse", "Socket connection timeout");
}
if (response_code == HttpStatus.SC_UNAUTHORIZED)
{
// credential check failed
Log.e("HTTP status", "unauthorised");
}
else if (response_code == HttpStatus.SC_FORBIDDEN)
{
// forbidden
Log.e("HTTP status", "Forbidden");
}
return response_code == HttpStatus.SC_OK ? EntityUtils.toString(response.getEntity()) : null;
}
