cocos2dx如何读取xml

这些天被cocos2dx如何读取xml困惑着，现在总结总结，如有错误，欢迎指正！

先新建一个cocos2dx的工程

HelloWorldScene.cpp中的代码如下：

[cpp] view plain copy

1. #include"HelloWorldScene.h"
3. usingnamespacecocos2d;
4. CCScene*HelloWorld::scene()
5. {
6. CCScene*scene=NULL;
7. do
8. {
9. //'scene'isanautoreleaseobject
10. scene=CCScene::create();
11. CC_BREAK_IF(!scene);
13. //'layer'isanautoreleaseobject
14. HelloWorld*layer=HelloWorld::create();
15. CC_BREAK_IF(!layer);
16. //addlayerasachildtoscene
17. scene->addChild(layer);
18. }while(0);
19. //returnthescene
20. returnscene;
21. }
22. //on"init"youneedtoinitializeyourinstance
23. boolHelloWorld::init()
24. boolbRet=false;
25. //////////////////////////////////////////////////////////////////////////
26. //superinitfirst
27. CC_BREAK_IF(!CCLayer::init());
28. //addyourcodesbelow...
29. //1.Addamenuitemwith"X"image,whichisclickedtoquittheprogram.
30. //Createa"close"menuitemwithcloseicon,it'sanautoreleaseobject.
31. CCMenuItemImage*pCloseItem=CCMenuItemImage::create(
32. "CloseNormal.png",
33. "CloseSelected.png",
34. this,153); list-style:decimal-leading-zero outside; color:inherit; line-height:18px; margin:0px!important; padding:0px 3px 0px 10px!important"> menu_selector(HelloWorld::menuCloseCallback));
35. CC_BREAK_IF(!pCloseItem);
36. //Placethemenuitembottom-rightconner.
37. pCloseItem->setPosition(ccp(CCDirector::sharedDirector()->getWinSize().width-20,20));
38. //Createamenuwiththe"close"menuitem,it'sanautoreleaseobject.
39. CCMenu*pMenu=CCMenu::create(pCloseItem,NULL);
40. pMenu->setPosition(CCPointZero);
41. CC_BREAK_IF(!pMenu);
42. //AddthemenutoHelloWorldlayerasachildlayer.
43. this->addChild(pMenu,1);
44. //2.Addalabelshows"HelloWorld".

50. pDict_2->retain();
51. pDict_2=(CCDictionary*)pDict->objectForKey("special");
52. /*
53. 如果在同一个key下面存在<string>hhhhh</string>
54. <string>comeontom</string>
55. <true></true>
56. 这些关键词，则输出最后一个

58. CCLOG("pDict_2:%s",((CCString*)pDict_2->valueForKey("special_1"))->getCString());

strings.xml代码如下：
