// 1. url
NSURL *url = [NSURL URLWithString:@"http://192.168.10.9/videos.xml"];

// 2. 请求
NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:1 timeoutInterval:2.0f];

// 3. 连接
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {

// 将XML整个读入内存, 对应的就是GDataXMLDocument对象
GDataXMLDocument *document = [[GDataXMLDocument alloc] initWithData:data error:NULL];

//        NSLog(@"%@", document.rootElement.children);// document.rootElement.children--》videos

for (GDataXMLElement *element in document.rootElement.children) {

//            NSLog(@"---->%@", element); // ---> 对应的是video对象
// 创建video对象
Video *video = [[Video alloc] init];

// 这个遍历就是取出Video对应的所有属性值
for (GDataXMLElement *node in element.children) {
//                NSLog(@"＝＝＝>%@ ---> %@", node.name, node.stringValue);
// 在这里给给对象赋值
[video setValue:node.stringValue forKeyPath:node.name];
}

// 跟踪attributes
//            NSLog(@"%@", element.attributes);
// 遍历element.attributes数组，拿到属性值
for (GDataXMLNode *att in element.attributes) {

//                NSLog(@"att.name = %@ att.stringValue = %@", att.name, att.stringValue);

// kvc
[video setValue:att.stringValue forKeyPath:att.name];
}

// 模型添加到数组
[self.videos addObject:video];
