例程很简单,因此就不再啰嗦了,直接上代码。
test.xml内容:
<?xml version="1.0"?> <scene name="Depth"> <surface id="A001" type="Camera"> <eye>0 10 10</eye> <front>0 0 -1</front> <refUp>0 1 0</refUp> <fov>90</fov> </surface> <surface id="A002" type="Sphere"> <center>0 10 -10</center> <radius>10</radius> </surface> <surface id="A003" type="Plane"> <direction>0 10 -10</direction> <distance>10</distance> </surface> </scene>
读XML的例程:
#include <iostream> #include "tinyxml2.h" using namespace std; using namespace tinyxml2; int main( int argc,char* argv[] ) { XMLDocument doc; if ( doc.LoadFile("test.xml") ) { doc.PrintError(); exit( 1 ); } // 根元素 XMLElement* scene = doc.RootElement(); cout << "name:" << scene->Attribute( "name" ) << endl << endl; // 遍历<surface>元素 XMLElement* surface = scene->FirstChildElement( "surface" ); while (surface) { // 遍历属性列表 const XMLAttribute* surfaceAttr = surface->FirstAttribute(); while ( surfaceAttr ) { cout << surfaceAttr->Name() << ":" << surfaceAttr->Value() << " "; surfaceAttr = surfaceAttr->Next(); } cout << endl; // 遍历子元素 XMLElement* surfaceChild = surface->FirstChildElement(); while (surfaceChild) { cout << surfaceChild->Name() << " = " << surfaceChild->GetText() << endl; surfaceChild = surfaceChild->NextSiblingElement(); } cout << endl; surface = surface->NextSiblingElement( "surface" ); } return 0; }
写XML的例程:
#include <iostream> #include "tinyxml2.h" using namespace std; using namespace tinyxml2; int main( int argc,char* argv[] ) { XMLDocument doc; // 创建根元素<China> XMLElement* root = doc.NewElement( "China" ); doc.InsertEndChild( root ); // 创建子元素<City> XMLElement* cityElement = doc.NewElement( "City" ); cityElement->SetAttribute( "name","WuHan" ); // 设置元素属性 root->InsertEndChild( cityElement ); // 创建孙元素<population> XMLElement* populationElement = doc.NewElement( "population" ); populationElement->SetText( "8,000,000" ); // 设置元素文本 cityElement->InsertEndChild( populationElement ); // 创建孙元素<area> XMLElement* areaElement = doc.NewElement( "area" ); XMLText* areaText = doc.NewText( "10000" ); areaElement->InsertEndChild( areaText ); // 设置元素文本 cityElement->InsertEndChild( areaElement ); // 输出XML至文件 cout << "output xml to '1.xml'" << endl << endl; doc.SaveFile( "1.xml" ); // 输出XML至内存 cout << "output xml to memory" << endl << "--------------------" << endl; XMLPrinter printer; doc.Print( &printer ); cout << printer.CStr(); return 0; }
生成的1.xml内容:
<China> <City name="WuHan"> <population>8,000</population> <area>10000</area> </City> </China>
