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 = 0; i<3; 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>
