How display image for different RSSfedd's Key. like (media:content , image, thumbnail)

[badalpub1991]

I am working on RSSFeed project. i want to fetch data from five different url's XML.

1. http://rss.news.yahoo.com/rss/world - Yahoo.com

2. http://news.google.com/news?pz=1&ned=us&hl=en&topic=w&output=rss - Google.com

3. http://rssfeeds.usatoday.com/UsatodaycomWorld-TopStories - USA Today

I am able to Fetch data like Title and Description or etc with

Object for key @"Ttile" and Object for key "@PUBDATE"

But in Terms of Image all RSS Feed using Different Key for image Like
Object for key @"image" , Object for key @"src" , Object for key @"Media:content"

I am able to fetch few of the Image with Objectforkey:@"media:content"
but other link uses different Objectforkey like @"image" or @"Media:thumbline".

How can i fetch it this different key or how can i set it in single tableview?

I am Using MWFeedParser for XML Parsing.

Here is my code from which i am able to fetch image with objectforkey:@"Media:content" but i can't understand how to set other keys for image.

    //MWFeeditem.h
#import <Foundation/Foundation.h>
@interface MWFeedItem : NSObject <NSCoding> {

NSString *identifier; // Item identifier
NSString *title; // Item title
NSString *link; // Item URL
NSDate *date; // Date the item was published
NSDate *updated; // Date the item was updated if available
NSString *summary; // Description of item
NSString *content; // More detailed content (if available)
NSString *author; // Item author
NSString *image; // image for the feed

// Enclosures: Holds 1 or more item enclosures (i.e. podcasts, mp3. pdf, etc)
//  - NSArray of NSDictionaries with the following keys:
//     url: where the enclosure is located (NSString)
//     length: how big it is in bytes (NSNumber)
//     type: what its type is, a standard MIME type  (NSString)
NSArray *enclosures;

}

@property (nonatomic, copy) NSString *identifier;
@property (nonatomic, copy) NSString *title;
@property (nonatomic, copy) NSString *link;
@property (nonatomic, copy) NSDate *date;

@property (nonatomic, copy) NSString *author;
@property (nonatomic, copy) NSArray *enclosures;
@property (nonatomic, copy) NSString *image;
@end

    date = [decoder decodeObjectForKey:@"date"];

    author = [decoder decodeObjectForKey:@"author"];
    enclosures = [decoder decodeObjectForKey:@"enclosures"];

       }
 return self;
}

                        if ([self.currentElementAttributes objectForKey:@"url"])
                            item.image = self.currentElementAttributes[@"url"];

                }

and here is my UITableview Method where i have to set image in cell.

   - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

     static NSString *MainTableIdentifier = @"MainTableIdentifier";
     MainViewTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MainTableIdentifier];

 if (cell == nil)
  {
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MainViewTableViewCell" owner:self options:nil];
    cell = [nib objectAtIndex:0];
   }


MWFeedItem *item = [itemsToDisplay objectAtIndex:indexPath.row];
if (item) {

    // Process
    NSString *itemTitle = item.title ? [item.title stringByConvertingHTMLToPlainText] : @"[No Title]";
    NSString *itemSummary = item.summary ? [item.summary stringByConvertingHTMLToPlainText] : @"[No Summary]";


    cell.lblTitle.text = itemTitle;
    NSMutableString *subtitle = [NSMutableString string];
    if (item.date) [subtitle appendFormat:@"%@ ", [formatter stringFromDate:item.date]];
    //[subtitle appendString:itemSummary];
    cell.lblDateTime.text = subtitle;
    cell.lblDescription.text=itemSummary;


}
NSURL *url = [NSURL URLWithString:item.image];

   [cell.ImgMainView sd_setImageWithURL:url];
