Refreshing RSS data in TableView

Question

I am trying to refresh my TableView while I am parsing RSS. Once I update the xml and then I press on refresh button it wont make anything but when I close and open the app it runs the new updated xml. Where could be my problem?

-(void)refreshButton{

[self.MyTableView reloadData];

NSLog(@"RSS refreshed");
}

Thanks from now.

@LuaiKalkatawi: no, I'm asking where are you calling the parse method? The didStartElement method will work only after calling the parse method. — Midhun MP, Nov 20 '12 at 03:31
@LuaiKalkatawi: if you want to parse an XML, you need to call like: `[parser parse];` . Where did you wrote that ? — Midhun MP, Nov 22 '12 at 10:08

The issue is you are parsing the xml from the viewDidLoad. So if the xml is changed then you need to parse it again.

So change the refresh data method like:

-(void)refreshButton
{
  NSXMLParser *parser = [[NSXMLParser alloc] initWithData:newXMLData];
  [parser parse];
  [self.MyTableView reloadData];
}

newXMLData is an instance of NSData and it holds the XML file in the form of bytes.

Thanks it works :) I have small question where is the better place to parse the xml in? While I have parsed it in the `viewDidLoad`. – Luai Kalkatawi Nov 22 '12 at 10:49
For the first time it is in the viewDidLoad or viewDidAppear. and another place is in the refreshing methods. – Midhun MP Nov 22 '12 at 10:50
and call the [tableView reloadData] in the parserDidEndDocument method. That is the best place to reloadData – Midhun MP Nov 22 '12 at 10:52
I think I have to search about the `DidEndDocument` because I am using that method. – Luai Kalkatawi Nov 22 '12 at 11:47
