在开发cocos2dx跨平台网络游戏的时候，数据基本都会处理成xml格式。

cocos2dx封装了libxml，处理xml可以使用封装好的类CCSAXParser,

采用key - value ，key- value方式编辑的xml可以采用CCSAXParser。

我们编辑的xml大量使用到了key-value -Attribute ，就是数据基本都写在了属性里面，所以我采用了第三方库tinyxml

下面是代码实现：

voidHXmlParse::Read_questxml(constchar*docname,char*buf_,GameBoard*gameBoardinstance){TiXmlDocumentdoc(docname);//boolloadOkay=doc.LoadFile();if(strcmp(docname,"")!=0){//这个是从网络下载的文件，缓存到本地，所以有判断char*pBytes=GOEUtilies::getFileDataFromWriteablePath(docname);//CCLog("getFileData:%s|pBytes:%d",docname,size);doc.Parse((constchar*)pBytes,0,TIXML_ENCODING_UTF8);}else{doc.Parse((constchar*)buf_,0,TIXML_ENCODING_UTF8);}//if(!loadOkay)//{//CCLOG("Couldnotloadtestfile'%s'.Error='%s'.Exiting.\n",docname,doc.ErrorDesc());//return;//}TiXmlNode*noderoot=0;//therootnode//TiXmlNode*nodearray=0;TiXmlElement*todoElement=0;//thefirstnode,likeAccout,Crop...TiXmlElement*itemElement=0;//theAccout,Crop'selementlistnoderoot=doc.RootElement()->FirstChild();gameBoardinstance->_goeStaticData->quests_=newCCDictionary();for(todoElement=noderoot->FirstChildElement();todoElement;todoElement=todoElement->NextSiblingElement()){GOEStaticQuest*quest=newGOEStaticQuest();quest->questId_=atoi(todoElement->Attribute("id"));gameBoardinstance->_goeStaticData->questId_=quest->questId_;quest->needIds_=*(CCString::create(todoElement->Attribute("needid")));quest->nextIds_=*(CCString::create(todoElement->Attribute("nextid")));quest->newId_=atoi(todoElement->Attribute("newid"));quest->exp_=atoi(todoElement->Attribute("exp"));quest->resource_=atoi(todoElement->Attribute("recource"));quest->coin_=atoi(todoElement->Attribute("coin"));quest->card_=*(CCString::create(todoElement->Attribute("card")));quest->icon_=*(CCString::create(todoElement->Attribute("icon")));quest->power_=atoi(todoElement->Attribute("power"));gameBoardinstance->_goeStaticData->quests_->setObject((CCObject*)quest,quest->questId_);for(itemElement=todoElement->FirstChildElement();itemElement;itemElement=itemElement->NextSiblingElement()){GOEStaticTask*task=newGOEStaticTask();task->taskId_=atoi(itemElement->Attribute("id"));task->action_=*(CCString::create(itemElement->Attribute("action")));task->type_=*(CCString::create(itemElement->Attribute("type")));task->value_=*(CCString::create(itemElement->Attribute("value")));task->params_=*(CCString::create(itemElement->Attribute("params")));GOEStaticQuest*q=(GOEStaticQuest*)gameBoardinstance->_goeStaticData->quests_->objectForKey(gameBoardinstance->_goeStaticData->questId_);q->tasks_.addObject((CCObject*)task);}}}

可以对比xml，很容易理解代码，主要就是节点，然后遍历

<?xmlversion='1.0'encoding='UTF-8'standalone='no'?><goe:databasexmlns:goe='http://www.elex-tech.com/sns/platform/'xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'><quests><questid="301"icon="quest2"newid="0"needid="202"nextid="401"exp="0"recource="0"coin="0"card="0"power="0"><taskid="0"action="buildingHarvest"type="301"value="0"params="0"/></quest><questid="302"icon="quest2"newid="0"needid="204"nextid="402"exp="0"recource="0"coin="0"card="0"power="0"><taskid="0"action="buildingHarvest"type="401"value="0"params="0"/></quest></quests></goe:database>
