cocos2d-x使用tinyxml2存储解析xml

我用的是2.1.4的cocos2d-x,里面自带有tinyxml2库。

导入头文件：
#include "support/tinyxml2/tinyxml2.h"

using namespace tinyxml2;

一：创建xml并保存

void TinyXmlDemo::createTinyXMLFile()

{

    //储存XML文件的路径

    std::string    filePath = CCFileUtils::sharedFileUtils()->getWritablePath() + "tinyxmltest.xml";

    //xml文档

    tinyxml2::XMLDocument* pDoc = new tinyxml2::XMLDocument();

    if (pDoc == NULL)

    {

        return;

    }

     //xml声明

    XMLDeclaration* pDecl = pDoc->NewDeclaration("xml version=\"1.0\" encoding=\"UTF-8\"");

    if (pDecl == NULL)

    {

        return;

    }

    pDoc->LinkEndChild(pDecl);

    //节点plist

    XMLElement* plistElement = pDoc->NewElement("plist");

    plistElement->SetAttribute("version","1.0");

    pDoc->LinkEndChild(plistElement);

    //节点dict

    XMLElement* dictElement = pDoc->NewElement("dict");

    plistElement->LinkEndChild(dictElement);

    //节点key

    XMLElement* keyElement = pDoc->NewElement("key");

    keyElement->LinkEndChild(pDoc->NewText("keyText"));//给节点设置值

    dictElement->LinkEndChild(keyElement);

    //节点string

    XMLElement* stringElement = pDoc->NewElement("string");

    stringElement->LinkEndChild(pDoc->NewText("stringText"));//给节点设置值

    dictElement->LinkEndChild(stringElement);

    //节点array

    XMLElement* arrayElemet = pDoc->NewElement("array");

    dictElement->LinkEndChild(arrayElemet);

    for (int i = ; i<; i++)

    {

        XMLElement* strEle = pDoc->NewElement("string");

        strEle->LinkEndChild(pDoc->NewText("icon"));

        arrayElemet->LinkEndChild(strEle);

    }

    //保存文件

    pDoc->SaveFile(filePath.c_str());

    delete pDoc;

}

在win32上xml保存的路径是在D:\cocos2d-x-2.1.4\cocos2d-x-2.1.4\Debug.win32里面

<?xml version="1.0" encoding="UTF-8"?>

<plist version="1.0">

    <dict>

        <key>keyText</key>

        <string>stringText</string>

        <array>

            <string>icon</string>

            <string>icon</string>

            <string>icon</string>

        </array>

    </dict>

</plist>

二：解析xml

void TinyXmlDemo::parseTinyXMLFile()

{

    //储存XML文件的路径

    std::string    filePath = CCFileUtils::sharedFileUtils()->getWritablePath() + "tinyxmltest.xml";

    tinyxml2::XMLDocument* pDoc = new tinyxml2::XMLDocument();

    pDoc->LoadFile(filePath.c_str());

    //得到根节点

    XMLElement* rootElement = pDoc->RootElement();

    //打印根节点名字和值

    CCLog("%s,%s",rootElement->Value(),rootElement->GetText());

    //节点的第一个属性

    const XMLAttribute* attribute = rootElement->FirstAttribute();

    //打印属性的名字和值

    CCLog("%s %s",attribute->Name(),attribute->Value());

    //查找节点的属性值

    float value = 0.1f;

    rootElement->QueryFloatAttribute("version",&value);

    CCLog("%f",value);

    //设置节点属性值

    rootElement->SetAttribute("version", 1.4);

    //跟节点的第一个字节点 dict

    XMLElement *dictEle = rootElement->FirstChildElement();

    //dict下面的子节点 key

    XMLElement *keyEle = dictEle->FirstChildElement();

    //打印key节点的值

    CCLog("%s,%s",keyEle->Name(),keyEle->GetText());

    //key节点的next节点 string

    XMLElement *stringEle = keyEle->NextSiblingElement();

    CCLog("%s,%s",stringEle->Name(),stringEle->GetText());

    //string节点的子节点

    XMLElement *nulXmlEle = stringEle->FirstChildElement();

    if (NULL == nulXmlEle) {

        CCLog("string no childElement");

    }

    //array节点

    XMLElement *arrayEle= stringEle->NextSiblingElement();

    CCLog("%s,%s",arrayEle->Name(),arrayEle->GetText());

    XMLElement *array1 = arrayEle->FirstChildElement();

    CCLog("%s,%s",array1->Name(),array1->GetText());

    XMLElement *array2 = array1->NextSiblingElement();

    CCLog("%s,%s",array2->Name(),array2->GetText());

    XMLElement *array3 = arrayEle->LastChildElement();

    CCLog("%s,%s",array3->Name(),array3->GetText());

    //修改了xml记得保存

    pDoc->SaveFile(filePath.c_str());

}

打印输出：

plist,(null)
version 1.0
1.000000
key,keyText
string,stringText
string no childElement
array,(null)
string,icon
string,icon
string,icon

由于修改了节点属性值，保存后的xml

<?xml version="1.0" encoding="UTF-8"?>

<plist version="1.4">

    <dict>

        <key>keyText</key>

        <string>stringText</string>

        <array>

            <string>icon</string>

            <string>icon</string>

            <string>icon</string>

        </array>

    </dict>

</plist>
