Answer 1

NSMutableString *xmlString;

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)nameSpaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
    xmlString = [[NSMutableString alloc] init];    
}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
    [xmlString appendString:string];
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{    
    if ([elementName isEqualToString:@"ns2:value"])
    {
        if (![xmlString isEqual:@""])
        {
            NSLog(@"%@",xmlString);
            [SomeArray addObject:xmlString];
        }
    }

    //Release string
    [xmlString release];
    xmlString = nil;
}

這里NSMutableString是一個變量，用於跟蹤foundCharacters方法中的當前元素，並使用elementName追加字符串和didEndElement方法，我們可以識別該標記的值。

UPDATE

- (void)parserDidEndDocument:(NSXMLParser *)parser
{
    //update your UI here after parsing is finished
}
