    copied!<p>I'm parsing flight times in my iPhone app. </p> <p>Here's a snippet from the XML</p> <pre><code>&lt;?xml version="1.0" encoding="iso-8859-1"?&gt; &lt;airport xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"&gt; &lt;flights lastUpdate="2011-11-07T10:49:43"&gt; &lt;flight uniqueID="2131560"&gt; &lt;airline&gt;DY&lt;/airline&gt; &lt;flight_id&gt;DY1052&lt;/flight_id&gt; &lt;dom_int&gt;S&lt;/dom_int&gt; &lt;schedule_time&gt;2011-11-04T06:00:00&lt;/schedule_time&gt; &lt;arr_dep&gt;D&lt;/arr_dep&gt; &lt;airport&gt;SVG&lt;/airport&gt; &lt;via_airport&gt;CPH&lt;/via_airport&gt; &lt;check_in&gt;C&lt;/check_in&gt; &lt;/flight&gt; &lt;flight uniqueID="2136807"&gt; &lt;airline&gt;SK&lt;/airline&gt; &lt;flight_id&gt;SK308&lt;/flight_id&gt; &lt;dom_int&gt;D&lt;/dom_int&gt; &lt;schedule_time&gt;2011-11-07T07:15:00&lt;/schedule_time&gt; &lt;arr_dep&gt;D&lt;/arr_dep&gt; &lt;airport&gt;SVG&lt;/airport&gt; &lt;via_airport&gt;SVG&lt;/via_airport&gt; &lt;check_in&gt;EF&lt;/check_in&gt; &lt;/flight&gt; ... </code></pre> <p>I store each flight in a Flight object which looks like this:</p> <pre><code>@interface Flights : NSObject{ NSInteger flightUniqueID; NSString *airline; NSString *flight_id; NSString *dom_int; NSDate *schedule_time; NSString *arr_dep; NSString *airport; NSString *check_in; NSString *status; NSString *via_airport; NSString *gate; NSString *delayed; } @property(nonatomic, readwrite)NSInteger flightUniqueID; @property(nonatomic, retain)NSString *airline; @property(nonatomic, retain)NSString *flight_id; @property(nonatomic, retain)NSString *dom_int; @property(nonatomic, retain)NSDate *schedule_time; @property(nonatomic, retain)NSString *arr_dep; @property(nonatomic, retain)NSString *airport; @property(nonatomic, retain)NSString *check_in; @property(nonatomic, retain)NSString *status; @property(nonatomic, retain)NSString *via_airport; @property(nonatomic, retain)NSString *gate; @property(nonatomic, retain)NSString *delayed; </code></pre> <p>I use an NSXMLParser to parse the XML</p> <pre><code>- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict{ if ([elementName isEqualToString:@"airport"]) { allFlights = [[NSMutableArray alloc]init]; } else if([elementName isEqualToString:@"flight"]){ flight = [[Flights alloc]init]; flight.flightUniqueID = [[attributeDict objectForKey:@"uniqueID"]integerValue]; } } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(!currentElementValue) currentElementValue = [[NSMutableString alloc] initWithString:string]; else [currentElementValue appendString:string]; } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"flights"]) { return; } if ([elementName isEqualToString:@"flight"]) { NSLog(@"Adding object: %@" , flight); [allFlights addObject:flight]; [flight release]; flight = nil; }else [flight setValue:currentElementValue forKey:elementName]; [currentElementValue release]; currentElementValue = nil; } </code></pre> <p>When i NSLog "flight", I get this output:</p> <pre><code>Adding object: &lt;Flights: 0xsomenumber&gt; ... Adding object: &lt;Flights: 0x7064360&gt; </code></pre> <p>which goes on for however many flights there are in the xml.</p> <p>However, the array I add each object to only stores the last flight object. If I try to NSLog the array after the parsing is done, it prints out the last object, and nothing else.</p> <p>Obviously I need to have all the flights stored in the array, so I can show all of them in my tableview after the parsing is done. </p> <p>How can I achieve this? Am I missing something?</p> <p>I tried to parse the XML without releasing the flight object, but that didn't work either.</p>
