本次介绍如何在cocos2d-x上使用tinyXml库对于tinyxml我不做多介绍，不懂朋友度娘谷哥

tinyxml 在win32上是可以直接使用没啥问题。但是放到android上会出现路径找不到，这里就是要帮大家解决这个问题。其实这个代码是人家写的我改了一点让2.X可以使用。谢谢那位朋友。具体出处忘了真不好意思

其中引擎自带了一个解析器。里面是有文件路径获取方法的。那位朋友也是根据这个原来来修改tinyXml库

具体我吧代码弄上来,其实是给tinyXml加一个加载的成员函数如下

bool TiXmlDocument::LoadFileByCocos2d( const char * filename, TiXmlEncoding encoding /*= TIXML_ENCODING_UTF8*/ ){if ( !filename ) {SetError( TIXML_ERROR_OPENING_FILE, 0, 0, TIXML_ENCODING_UNKNOWN );return false;}// Delete the existing data:Clear();location.Clear();// Get the file size, so we can pre-allocate the string. HUGE speed impact.const char *pfilePath = CCFileUtils::sharedFileUtils()->fullPathFromRelativePath(filename);TIXML_STRING __filename( pfilePath );value = __filename;unsigned long length = 0;char *pBuffer =(char*) CCFileUtils::sharedFileUtils()->getFileData(pfilePath, "rt", &length);if (!pBuffer){SetError( TIXML_ERROR_OPENING_FILE, 0, 0, TIXML_ENCODING_UNKNOWN );return false;}// Strange case, but good to handle up front.if ( length <= 0 ){SetError( TIXML_ERROR_DOCUMENT_EMPTY, 0, 0, TIXML_ENCODING_UNKNOWN );return false;}const char* p = pBuffer;// the read headchar* q = pBuffer;// the write headconst char CR = 0x0d;const char LF = 0x0a;pBuffer[length] = 0;while( *p ) {assert( p < (pBuffer+length) );assert( q <= (pBuffer+length) );assert( q <= p );if ( *p == CR ) {*q++ = LF;p++;if ( *p == LF ) {// check for CR+LF (and skip LF)p++;}}else {*q++ = *p++;}}assert( q <= (pBuffer+length) );*q = 0;Parse( pBuffer, 0, encoding );return !Error();}bool TiXmlDocument::SaveFile( const char * filename ) const{// The old c stuff lives on...FILE* fp = TiXmlFOpen( filename, "w" );if ( fp ){bool result = SaveFile( fp );fclose( fp );return result;}return false;}//具体哪里加 自己找

bool loadConfig()//如何使用 简单个例子 自己看吧{bool ret=false;do {TiXmlDocument doc;TiXmlElement *elementRoot,*elementIndex,*elementLast,*elementChildIndex,*elementChildLast;TiXmlAttribute *attribute;int id;doc.LoadFileByCocos2d("config.xml");elementRoot=doc.FirstChildElement();                                attribute=elementIndex->FirstAttribute();id=attribute->IntValue();vector<Point>vecPoint;elementChildIndex=elementIndex->FirstChildElement("vertex");elementChildLast=(TiXmlElement *)elementIndex->LastChild("vertex");while(elementChildIndex!=elementChildLast){attribute=elementChildIndex->FirstAttribute();point.x=attribute->IntValue();attribute=attribute->Next();point.y=attribute->IntValue();vecPoint.push_back(point);elementChildIndex=elementChildIndex->NextSiblingElement();}attribute=elementChildIndex->FirstAttribute();point.y=attribute->IntValue();attribute=attribute->Next();point.x=attribute->IntValue();vecPoint.push_back(point);mapArray.insert(map<int_16_u,vector<Point> >::value_type(id,vecPoint));doc.Clear();ret = true;} while (0);return ret;}

android的Android.mk配置
