cocos2dx 3.1.1 用tinyxml2.h解释xml (C++)

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"?>

<scene name="Depth">

<node type="camera">
<eye>0 10 10</eye>

<front>0 0 -1</front>

<refUp>0 1 0</refUp>

<fov>90</fov>

</node>

<node type="Sphere">

<center>0 10 -10</center>

<radius>10</radius>

</node>

<node type="Plane">

<direction>0 10 -10</direction>

<distance>10</distance>

</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
