  • tinyxml2简单使用

    引入头文件

    <span style="font-size:18px;">#include "HelloWorldScene.h"
    #include "tinyxml2/tinyxml2.h"
    USING_NS_CC;
    using namespace tinyxml2;</span>


    生成xml

    <span style="font-size:18px;">void HelloWorld::makeXml(const char* fileName)
    {
        //写入路径
        std::string filePath = FileUtils::getInstance()->getWritablePath() + fileName;
        XMLDocument *pDoc = new XMLDocument();
        //头声明
        XMLDeclaration *pDecl = pDoc->NewDeclaration("xml=version="1.0" encoding="UTF-8"");
        pDoc->LinkEndChild(pDecl);
        //注释
        XMLComment *pCom = pDoc->NewComment("test xml");
        pDoc->LinkEndChild(pCom);
        
        XMLElement *plistEl = pDoc->NewElement("plist");
        plistEl->SetAttribute("version", "1.0");
        plistEl->SetAttribute("age", 10);
        pDoc->LinkEndChild(plistEl);
        
        XMLElement *dictEl = pDoc->NewElement("dict");
        plistEl->LinkEndChild(dictEl);
        
        XMLElement *keyEl = pDoc->NewElement("key");
        keyEl->LinkEndChild(pDoc->NewText("keyValue"));
        dictEl->LinkEndChild(keyEl);
        
        XMLElement *arrayEl = pDoc->NewElement("array");
        dictEl->LinkEndChild(arrayEl);
        for (int i = 0; i<2 ; i++)
        {
            XMLElement *nameEl = pDoc->NewElement("name");
            nameEl->LinkEndChild(pDoc->NewText("array value"));
            arrayEl->LinkEndChild(nameEl);
        }
        
        pDoc->SaveFile(filePath.c_str());
        pDoc->Print();
        delete pDoc;
    }</span>

    运行结果为:

    <span style="font-size:18px;"><?xml=version="1.0" encoding="UTF-8"?>
    <!--test xml-->
    <plist version="1.0" age="10">
        <dict>
            <key>keyValue</key>
            <array>
                <name>array value</name>
                <name>array value</name>
            </array>
        </dict>
    </plist></span>

    读取xml:

    void HelloWorld::parseXml(const char* fileName)
    {
        std::string filePath = FileUtils::getInstance()->getWritablePath() + fileName;
        XMLDocument *pDoc = new XMLDocument();
        XMLError errorID = pDoc->LoadFile(filePath.c_str());
        if (errorID != 0)
        {
            return;
        }
        
        XMLElement *rootEl = pDoc->RootElement();
        const XMLAttribute *attribute = rootEl->FirstAttribute();
        while (attribute)
        {
            CCLOG("name=%s, value = %s", attribute->Name(), attribute->Value());
            attribute = attribute->Next();
        }
        
        XMLElement *dictEl = rootEl->FirstChildElement("dict");
        XMLElement *keyEl = dictEl->FirstChildElement("key");
        if (keyEl)
        {
            CCLOG("key el is = %s", keyEl->GetText());
        }
        
        XMLElement *arrayEl = keyEl->NextSiblingElement();
        XMLElement *childEl = arrayEl->FirstChildElement();
        while (childEl)
        {
            CCLOG("child el is = %s", childEl->GetText());
            childEl = childEl->NextSiblingElement();
        }
        
    }

    结果为:
    cocos2d: name=version, value = 1.0
    cocos2d: name=age, value = 10
    cocos2d: key el is = keyValue
    cocos2d: child el is = array value
    cocos2d: child el is = array value
