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
