Any Hints and Solution really appreciated.

my methods are.

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

	
    NSLog(@"Processing Element: %@", elementName);


    }

    - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { 
	
    
    }

    - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName 
      namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
	

    }
