XML 解析思路大致相同 大家可以对比一下 方便使用
#import "ViewController.h"
#import "GdataxMLNode.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view,typically from a nib.
    
    NSString *path = [[NSBundle mainBundle] pathForResource:@"user" ofType:@"xml"];
    NSString *str = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
    
    //xml解析器
    GdataxMLDocument *document = [[GdataxMLDocument alloc] initWithXMLString:str options:0 error:nil];
    
    NSArray *array = [document nodesForXPath:@"/Users/User/name" error:nil];
    
    for (GdataxMLElement *nameElement in array)
    {
        NSLog(@"%@",[nameElement stringValue]);
        
//        [nameElement elementsForName:<#(NSString *)#>];
//        [nameElement attributeForName:<#(NSString *)#>];
    }
    
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
