-(void)startParsingForSendFriendRequest:(NSString )userID Friend:(NSString)friendID
{

NSString *urlString =[NSStringstringWithFormat:@"http:///user_id=%@&friend_id=%@",userID,friendID];

////NSLog(@"urlString : %@",urlString);
NSURL *xmlURL = [NSURL URLWithString:urlString];

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] initWithURL:xmlURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:30.0]autorelease];

NSURLResponse *returnedResponse = nil;
NSError *returnedError = nil;
NSData *itemData  = [NSURLConnection sendSynchronousRequest:request returningResponse:&returnedResponse error:&returnedError];
//NSString *itemString = [[[NSString alloc] initWithBytes:[itemData bytes] length:[itemData length] encoding:NSUTF8StringEncoding]autorelease];

//NSLog(@"itemString : %@",itemString);


NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:itemData];       
[xmlParser setDelegate:self];

[xmlParser parse];

}
