cocos2dx 3.1.1 用tinyxml2.h解释xml (C++)

cocos2dx 3.1.1怎样用tinyxml2.h解释xml? (C++)@H_403_2@

cocos2dx已经自带了tinyxml2用于xml的解释,很早之前从2.x的版本开始已经无需再特地去下载.@H_403_2@

不过,tinyxm2关于3.x引擎的文档比较少,特此来贡献一个!@H_403_2@
@H_403_2@

@H_403_2@

首先加入头文件:

#include"cocos-ext.h”

#include "tinyxml2/tinyxml2.h”

using namespace tinyxml2;

using@H_403_2@namespace@H_403_2@std@H_403_2@;@H_403_2@

例子1:

text.xml文件内容如下

<?xml version="1.0"?>

<Hello>World</Hello>

xml解释:

[cpp]view plaincopy 
     
 stringfile_path=FileUtils::getInstance()->fullPathForFilename(@H_403_2@"testset.xml"@H_403_2@);@H_403_2@//如果新建的是lua项目中需要写("res/text.xml");@H_403_2@@H_403_2@@H_403_2@
 log("externalfilepath=%s"@H_403_2@,file_path.c_str());@H_403_2@@H_403_2@
 XMLDocumentdoc;@H_403_2@
 //加载文件@H_403_2@@H_403_2@@H_403_2@
 doc.LoadFile(file_path.c_str());@H_403_2@
 const@H_403_2@@H_403_2@char@H_403_2@*content=doc.FirstChildElement(@H_403_2@"Hello"@H_403_2@)->GetText();@H_403_2@@H_403_2@
 log("Hello,%s"@H_403_2@,content);@H_403_2@@H_403_2@

输出结果Hello,World

例子2:

hello.xml文件内容

<?xml version="1.0"@H_403_2@?>

<scenename@H_403_2@="Depth"@H_403_2@>

@H_403_2@<node@H_403_2@type@H_403_2@=@H_403_2@"camera">@H_403_2@

<eye>@H_403_2@0 10 10</eye>@H_403_2@

@H_403_2@<front>0 0 -1@H_403_2@</front>

@H_403_2@<refUp>0 1 0@H_403_2@</refUp>

@H_403_2@<fov>90@H_403_2@</fov>

@H_403_2@</node>

=@H_403_2@"Sphere">@H_403_2@

@H_403_2@<center>0 10 -10@H_403_2@</center>

@H_403_2@<radius>10@H_403_2@</radius>

@H_403_2@</node>

@H_403_2@<nodetype@H_403_2@="Plane"@H_403_2@>

@H_403_2@<direction>0 10 -10@H_403_2@</direction>

@H_403_2@<distance>10@H_403_2@</distance>

</scene>

xml解析:

[cpp] 
      @L_301_4@ 
      copy 
      
 stringfile_path=FileUtils::getInstance()->fullPathForFilename(@H_403_2@"hello.xml"@H_403_2@);@H_403_2@@H_403_2@
403_2@@H_403_2@
 @H_403_2@
 @H_403_2@
 XMLDocumentdocument;@H_403_2@
 document.LoadFile(file_path.c_str());@H_403_2@
 XMLElement*scene=document.RootElement();@H_403_2@
 XMLElement*surface=scene->FirstChildElement("node"@H_403_2@);@H_403_2@@H_403_2@
 while@H_403_2@(surface)@H_403_2@@H_403_2@
 {@H_403_2@
 XMLElement*surfaceChild=surface->FirstChildElement();@H_403_2@
char@H_403_2@*content;@H_403_2@@H_403_2@
const@H_403_2@XMLAttribute*attributeOfSurface=surface->FirstAttribute();@H_403_2@@H_403_2@
 log("%s:%s"@H_403_2@,attributeOfSurface->Name(),attributeOfSurface->Value());@H_403_2@@H_403_2@
while@H_403_2@(surfaceChild)@H_403_2@@H_403_2@
 {@H_403_2@
 content=surfaceChild->GetText();@H_403_2@
 surfaceChild=surfaceChild->NextSiblingElement();@H_403_2@
 log("%s"@H_403_2@,content);@H_403_2@@H_403_2@
 }@H_403_2@
 surface=surface->NextSiblingElement();@H_403_2@
 }@H_403_2@

输出结果:

cocos2d: type:camera

cocos2d: 0 10 10

cocos2d: 0 0 -1

cocos2d: 0 1 0

cocos2d: 90

cocos2d: type:Sphere

cocos2d: 0 10 -10

cocos2d: 10

cocos2d: type:Plane

cocos2d: 0 10 -10

cocos2d: 10
