So set up NSXML parser and its delegate and you will need the method below.
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
Then go through the XML file element by element and pull out the data you want i.e. something like this
if ([elementName isEqualToString:@"abc"]){
//Store in NSDictionary
if (!abc)
abc = [[NSDictionary alloc] init];
// Set current image for NSDictionary Image...
self.XMLImageToDisplay.image=[UIImage imageNamed:[NSDictionary productDictionary objectForKey:@"abc"]];
}
You could also then call it later and get the image with something like this if for example your using it in a UITableView:
cell.image.image = [UIImage imageNamed:[productDictionary objectForKey:@"abc"]];
Without seeing your code I can't properly comment, I hope this helps or sets you on the right track at least!
