    samplearray = [[NSMutableArray alloc]init];
    xmlParserObject = [[NSXMLParser alloc] initWithData:webData];
    [xmlParserObject setDelegate:self];
    [xmlParserObject parse];
    for (int i =0; i<[rssOutputData count]; i++) {
        Login *log = [rssOutputData objectAtIndex:i];
        sessid = log.userId;
        NSLog(@"%d",sessid);
        stat = log.status;
        NSLog(@"%@",stat);
        [samplearray addObject:log];
    }

    [connection release];

}

@end

```

Here is the loop which is not working

```
-(void)connectionDidFinishLoading:(NSURLConnection *)connection {
        samplearray = [[NSMutableArray alloc]init];
        xmlParserObject = [[NSXMLParser alloc] initWithData:webData];
        [xmlParserObject setDelegate:self];
        [xmlParserObject parse];
        for (int i =0; i<[rssOutputData count]; i++) {
            Login *log = [rssOutputData objectAtIndex:i];
            sessid = log.userId;
            NSLog(@"%d",sessid);
            stat = log.status;
            NSLog(@"%@",stat);
            [samplearray addObject:log];
        }

        [connection release];

    }

```

Here is the console output(output of parsed xml) :
