Iphone NSXMLParser NSCFString memory leak

The leak occurred in the didStartElement method. I was copying elementName without releasing it.

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

    NewsCurrentElement = [[elementName copy] autorelease];
    if ([elementName isEqualToString:NewsItemType]) 
    {
        // clear out our story item caches...
        NewsItem = [[NSMutableDictionary alloc] init];
        NewsCurrentElement1 = [[NSMutableString alloc] init];
        NewsCurrentElement2 = [[NSMutableString alloc] init];
        if(NewsNumElements == 3)
        {
            NewsCurrentElement3 = [[NSMutableString alloc] init];
        }

    }

}

You might also want to release (if necessary) the allocated NSMutableString properties before allocating another NSMutableString into the property like so:

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

    if (NewsCurrentElement) {
        [NewsCurrentElement release], NewsCurrentElement = nil;
    }
    NewsCurrentElement = [[elementName copy] autorelease];

    if ([elementName isEqualToString:NewsItemType]) {
        // clear out our story item caches...
        if (NewsItem) {
            [NewsItem release], NewsItem = nil;
        }
        NewsItem = [[NSMutableDictionary alloc] init];

        if (NewsCurrentElement1) {
            [NewsCurrentElement1 release], NewsCurrentElement1 = nil;
        }
        NewsCurrentElement1 = [[NSMutableString alloc] init];

        if (NewsCurrentElement2) {
            [NewsCurrentElement2 release], NewsCurrentElement2 = nil;
        }
        NewsCurrentElement2 = [[NSMutableString alloc] init];

        if(NewsNumElements == 3) {
            if (NewsCurrentElement3) {
                [NewsCurrentElement3 release], NewsCurrentElement3 = nil;
            }
            NewsCurrentElement3 = [[NSMutableString alloc] init];
        }
    }
}
