iphone - 如何在 iPhone 上使用 NSXML 解析器获取所有值

Question

我只能解析此 xml 的第一个元素，但我想获取美食的所有内容这是我的 xml

<cuisines>
<cuisine>Asian</cuisine>
<cuisine>Nepalese</cuisine>
<cuisine>North Indian</cuisine>
<cuisine>Indian Vegetarian</cuisine>
<cuisine>Organic Cuisine</cuisine>
</cuisines>

这是要解析的代码

if ( [elementName isEqualToString:@"cuisines"]) {


        if ( [elementName isEqualToString:@"cuisine"] ) {



            elementName=[[NSMutableString alloc] init];

            keyInProgress = [elementName copy];

            // This is a string we will append to as the text arrives
            textInProgress = [[[NSMutableString alloc] init]autorelease];

            return;
        }

但它不起作用，我想获得所有的值(value)

您需要实现解析器方法以及以下 NSXMLParserDelegate 协议(protocol)方法:

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

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

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