返回子元素节点(如NSXMLElement对象)的接收方指定的名字

- (NSArray *)elementsForName:(NSString *)name

Parameters

name

A string specifying the name of the child element nodes to find and return. If name is a qualified name, then this method invokes elementsForLocalName:URI: with the URI parameter set to the URI associated with the prefix. Otherwise comparison is based on string equality of the qualified or non-qualified name.

一个字符串指定子元素节点的名称查找并返回。如果名称是一个合格的名称,那么这个方法调用elementsForLocalName:URI:URI参数设置为与前缀相关联的URI。否则比较是基于平等的合格或没有名称的字符串。

Return Value

An array of of NSXMLElement objects or an empty array if no matching children can be found.

rootElement
