很简单。只需运行NSXMLParser，然后查找命名空间元素。

例如，在didStartElement中，为您想要的每个元素执行类似的操作：

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict { 
    NSString *firstName = [attributeDict objectForKey:@"FirstName"]];
}
