Gdata XML解析配置和简单使用
导入libxml2,使用第三方AFNetworking网络请求,第三方XML解析GData
GData需要的配置 Build Settings 里搜索,添加如下
如果是ARC ,需要加上 -fno-objc-arc
首先找一个xml网址使用AFNetworking请求得到NSData数据
#define HTTP_URL_GET @"http://lab.hudong.com/ipad/zutujingxuan.xml"
- (void)getRequest { AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] init]; //返回数据解析 manager.responseSerializer = [AFHTTPResponseSerializer serializer]; //AFJSONResponseSerializer responseObject就是jeson解析后的对象(有可能是字典) //AFXMLParserResponseSerializer responseObject就是NSXMLPareser对象 //AFHTTPRequestOperationManager responseObject就是NSData [manager GET:HTTP_URL_GET parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"%@",responseObject); // NSXMLParser [self xml:responseObject]; } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"error:%@.",error.localizedDescription); }]; }
先打开火狐浏览器看xml的层次结构(复制网址在火狐浏览器上打开)
使用GData解析,记住一层一层解析
- (void)xml:(NSData *)data { //创建一个解析对象 GDataXMLDocument *document = [[GDataXMLDocument alloc]initWithData:data options:0 error:nil]; //获取根节点 GDataXMLElement *rootElement = document.rootElement; NSLog(@"name: %@,stringvaule: %@",rootElement.name,rootElement.stringValue); GDataXMLElement *channeName = [rootElement elementsForName:@"channelName"].firstObject; NSLog(@"%@---%@",channeName.name,channeName.stringValue); //取多组 // //docInfo 直接跳过前面的子节点,知道取到名字对应的子节点 // NSArray *docInfos = [rootEiement nodesForXPath:@"//docInfo" error:nil] NSArray *docInfos = [[rootElement elementsForName:@"docList"].firstObject elementsForName:@"docInfo"]; for (GDataXMLElement *docInfoElement in docInfos) { NSMutableDictionary * dic = [NSMutableDictionary dictionary]; for (GDataXMLElement *elment in [docInfoElement children]) { [dic setObject:elment.stringValue forKey:elment.name]; } [_allInfos addObject:dic]; } NSLog(@"%@",_allInfos); }
最后是用一个全局的NSMutableArray接收打印,~
