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

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.

不过,tinyxm2关于3.x引擎的文档比较少,特此来贡献一个!

首先加入头文件:

#include"cocos-ext.h”

#include "tinyxml2/tinyxml2.h”

using namespace tinyxml2;

usingnamespacestd;

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("testset.xml");//如果新建的是lua项目中需要写("res/text.xml");
 log("externalfilepath=%s",file_path.c_str());
 XMLDocumentdoc;
 //加载文件
 doc.LoadFile(file_path.c_str());
 constchar*content=doc.FirstChildElement("Hello")->GetText();
 log("Hello,%s",content);

输出结果Hello,World

例子2:

hello.xml文件内容

<?xml version="1.0"?>

<scenename="Depth">

<nodetype="camera">

</node>

="Sphere">

</node>

<nodetype="Plane">

</scene>

xml解析:

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

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
