下面是創建XML代碼：

//創建一個名稱為test22.xml文件 int CreateXml() {rapidxml::xml_document<> doc;rapidxml::xml_node<>* rot = doc.allocate_node(rapidxml::node_pi, doc.allocate_string("xml version='1.0' encoding='utf-8'"));doc.append_node(rot);rapidxml::xml_node<>* node = doc.allocate_node(rapidxml::node_element, "config", "information");doc.append_node(node);rapidxml::xml_node<>* color = doc.allocate_node(rapidxml::node_element, "color", NULL);node->append_node(color);color->append_node(doc.allocate_node(rapidxml::node_element, "red", "0.1"));color->append_node(doc.allocate_node(rapidxml::node_element, "green", "0.1"));color->append_node(doc.allocate_node(rapidxml::node_element, "blue", "0.1"));color->append_node(doc.allocate_node(rapidxml::node_element, "alpha", "1.0"));rapidxml::xml_node<>* size = doc.allocate_node(rapidxml::node_element, "size", NULL);size->append_node(doc.allocate_node(rapidxml::node_element, "x", "640"));size->append_node(doc.allocate_node(rapidxml::node_element, "y", "480"));node->append_node(size);rapidxml::xml_node<>* mode = doc.allocate_node(rapidxml::node_element, "mode", "screen mode");mode->append_attribute(doc.allocate_attribute("fullscreen", "false"));node->append_node(mode);std::string text;rapidxml::print(std::back_inserter(text), doc, 0);std::cout << text << std::endl;//std::ofstream out("./ljtconfig/ljtconfig1.xml");std::ofstream out("E:/canDel/ConsoleApplication1/x64/Release/test22.xml");out << doc;return 0; }
