我是一个单线程妞～

NSString* path = [[NSBundle mainBundle] pathForResource:@"StudentXML" ofType:@"xml"];    NSData* data = [[NSData alloc] initWithContentsOfFile:path];    GDataXMLDocument* doc = [[GDataXMLDocument alloc] initWithData:data options:0 error:nil];    GDataXMLElement* root = [doc rootElement];//所有内容        // 取标签中的内容方法:1，路径。2，childAtIndex    //(1)路径    NSArray* fistName = [root nodesForXPath:@"//student/name/fistName" error:nil];// 所t有标签为fistName的元素。    NSLog(@"1:%@",[[fistName objectAtIndex:1] stringValue]);    // (2)childAtIndex    GDataXMLNode* lastName = [[[root childAtIndex:1] childAtIndex:0] childAtIndex:1];    NSLog(@"2:%@",[lastName stringValue]);

解析稍微复杂的页面：http://api.hudong.com/iphonexml.do?type=focus-c

代码如下：

#import "ViewController.h"@interface ViewController ()@end@implementation ViewController@synthesize recieveData = _recieveData;- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil{    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];    if (self) {        // Custom initialization    }    return self;}- (void)viewDidLoad{    [super viewDidLoad];    NSURL* url = [NSURL URLWithString:@"http://api.hudong.com/iphonexml.do?type=focus-c"];        NSURLRequest* request = [NSURLRequest requestWithURL:url];    [NSURLConnection connectionWithRequest:request delegate:self];            // Do any additional setup after loading the view from its nib.}- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{    _recieveData = [[NSMutableData alloc] init];    }- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{    [self.recieveData  appendData:data];}- (void)connectionDidFinishLoading:(NSURLConnection *)connection{    NSString* str = [[NSString alloc] initWithData:self.recieveData encoding:NSUTF8StringEncoding];        _recieveData = nil;        GDataXMLDocument* doc = [[GDataXMLDocument alloc] initWithXMLString:str options:0 error:nil];    GDataXMLElement* root = [doc rootElement];         NSArray* array =[root nodesForXPath:@"//response/docList/docInfo" error:nil];    for (int i =0; i<array.count; i++) {         NSLog(@"每项内容的题目：%@",[[[[array objectAtIndex:i] elementsForName:@"docTitle"] objectAtIndex:0] stringValue] );    }                       _recieveData = nil;        }- (void)didReceiveMemoryWarning{    [super didReceiveMemoryWarning];    // Dispose of any resources that can be recreated.}@end
