以上是一个简单 的xml文件

GDataXMLNode使用方法:

// xml解析
- (NSArray *)readDataOfXML
{
NSString *path = [[NSBundle mainBundle] pathForResource:@"Categories"
ofType:@"xml"];
NSData *xmlData = [NSData dataWithContentsOfFile:path];

//使用NSData对象初始化
GDataXMLDocument *doc = [[GDataXMLDocument alloc] initWithData:xmlData options:0
error:nil];
// 获取根节点 root
GDataXMLElement *rootElement = [doc rootElement];

//获取根节点下的节点（categories）
NSArray *categories = [rootElement elementsForName:@"categories"];
NSMutableArray *categoryArray = [NSMutableArray array];
NSMutableDictionary *dataDic = [NSMutableDictionary dictionary];
// 遍历数组
for (GDataXMLElement *element in categories) {
// 子节点数组中的第一个就是category_name 拿出来 作为字典的key
GDataXMLElement *nameElement = [[element elementsForName:@"category_name"]
objectAtIndex:0];
NSString *category_name = [nameElement stringValue];
// NSLog(@"%@", category_name);
[categoryArray addObject:category_name];
// 获取所有subcategories的子节点
NSArray *array = [element elementsForName:@"subcategories"];
NSMutableArray *tempArray = [NSMutableArray array];
// 遍历array 取得对应的值
for (GDataXMLElement *elem in array) {
NSString *str = [elem stringValue];
[tempArray addObject:str];
}
[dataDic setObject:tempArray forKey:category_name];
}
NSArray *arr = @[categoryArray, dataDic];
return arr;
}
