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;

using namespace std;

例子1:

text.xml文件内容如下

<?xml version="1.0"?>

<Hello>World</Hello>

xml解释:

    string file_path = FileUtils::getInstance()->fullPathForFilename("testset.xml");//如果新建的是lua项目中需要写("res/text.xml");    log("external file path = %s",file_path.c_str());    XMLDocument doc;    //加载文件    doc.LoadFile(file_path.c_str());    const char* 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"?>

</node>

</node>

</node>

</scene>

xml解析:

    string file_path = FileUtils::getInstance()->fullPathForFilename("hello.xml");    log("external file path = %s",file_path.c_str());    XMLDocument document;    document.LoadFile(file_path.c_str());    XMLElement *scene=document.RootElement();    XMLElement *surface=scene->FirstChildElement("node");    while (surface)    {        XMLElement *surfaceChild=surface->FirstChildElement();        const char* content;        const XMLAttribute *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
