Answer 1

有有效的两种方法来解析XML - 事件驱动的一个（如由使用的NSXMLParser）和树的方法（如通过使用NSXML ）。

如果您只是在特定元素之后，那么使用NSXML使用的树方法可能会容易得多，因为它可以使您使用XPath（实际上是XQuery）查询XML文档以返回特定节点等你感兴趣。

如果这听起来像是使用NSXMLParser遍历整个结构可能是更有成效的方法，那么我建议读the Introduction to Tree-Based XML Programming Guide for Cocoa。 （在“查询XML文档”部分应该是特别感兴趣的。）

Answer 2

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{  
    if ([elementName isEqualToString:@"book"]) 
    { 
    item = [[NSMutableDictionary alloc] init]; 

     item_name = [[NSMutableString alloc] initWithString:[attributeDict valueForKey:@"name"]]; 
} 

//然后在ITEM_NAME你有值创
//尝试解析这样
编辑：看了之后注释

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

      item_name1 = [[NSMutableString alloc] initWithString:[attributeDict valueForKey:@"number"]]; 
    } 

//在item_name1你将得到的值作为1次
