xml parsing to fetch image data from the url

aEventInfo.event_Picture is an NSString?? and you are initializing it properly? because the code to retrieve the image seems to be ok, your problem seems to be the string you are passing to get the URL.

It should be something like:

NSString* urlString= @"http://static.djguide.nl/image/flyers/2010/120/91426front.jpg";

and then NSURL *url3 = [NSURL URLWithString:urlString];

I respect Open..source

This is my code.... //Parsing class.....

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName 
  namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName 
    attributes:(NSDictionary *)attributeDict{

    if ([elementName isEqualToString:@"events"]) {
        appDelegate.eventListArray=[[NSMutableArray alloc]init];
}
    if ([elementName isEqualToString:@"event"]) {
//      NSString * stringValue = [attributeDict objectForKey:@"id"];
//      [appDelegate.eventListArray addObject:stringValue];
        aEventInfo=[[EventInfo alloc]init];

        aEventInfo.event_ID=[attributeDict objectForKey:@"id"];
        aEventInfo.event_Title=[attributeDict objectForKey:@"title"];
        aEventInfo.event_Description=[attributeDict objectForKey:@"description"];
        aEventInfo.event_Date=[attributeDict objectForKey:@"date"];
        aEventInfo.event_Time=[attributeDict objectForKey:@"time"];
        aEventInfo.event_Location=[attributeDict objectForKey:@"location"];
        aEventInfo.event_Street=[attributeDict objectForKey:@"street"];
        aEventInfo.event_City=[attributeDict objectForKey:@"city"];
        aEventInfo.event_Visitors=[attributeDict objectForKey:@"visitors"];
        aEventInfo.event_Organisation=[attributeDict objectForKey:@"organisation"];
        aEventInfo.event_Price=[attributeDict objectForKey:@"price"];
        aEventInfo.event_Minimum_Age=[attributeDict objectForKey:@"minimum_age"];
        aEventInfo.event_Picture=[attributeDict objectForKey:@"picture"];
        aEventInfo.event_Genre=[attributeDict objectForKey:@"genre"];
        aEventInfo.event_LineUP=[attributeDict objectForKey:@"lineup"];
        aEventInfo.event_WebSite=[attributeDict objectForKey:@"website"];

    }
}

Have you tried using TouchXML. XML parsing becomes very easy to use with TouchXML. I was facing the same problem using NSXMLParser. Switched over to TouchXML, and XML parsing became easier.
