Question

如何将RapidXML中的内容保存到xml文件？我的应用程序是MFC，我使用CString很多，因为它更容易操纵字符串。因此，如果我有下面的代码，我该如何保存到xml文件？

#include "rapidxml.hpp"
rapidxml::xml_document<> doc;
rapidxml::xml_node<>* decl = doc.allocate_node(rapidxml::node_type::node_declaration, 0,0,0,0);
decl->append_attribute(doc.allocate_attribute("xml version", "1.0"));
doc.append_node(decl);  

rapidxml::xml_node<>* comment = doc.allocate_node(rapidxml::node_type::node_comment, 0, "Application Config");
doc.append_node(comment);

rapidxml::xml_node<>* subsytem = doc.allocate_node(rapidxml::node_type::node_element, "Subsystem");
subsytem->append_attribute(doc.allocate_attribute("Name", "My App"));
subsytem->append_attribute(doc.allocate_attribute("Version", "1.0"));
doc.append_node(subsytem);

感谢。

using namespace rapidxml;
int testmain()
{
    xml_document<> doc;
    xml_node<>* decl = doc.allocate_node(node_declaration);
    decl->append_attribute(doc.allocate_attribute("version", "1.0"));
    decl->append_attribute(doc.allocate_attribute("encoding", "UTF-8"));
    doc.append_node(decl);  



    xml_node<> *files = doc.allocate_node(node_element, "Files");
    doc.append_node(files);
    xml_attribute<> *attr = doc.allocate_attribute("dummy", "google.com");
    files->append_attribute(attr);

    for(int i = 0;i<10;++i)
    {
        xml_node<> *file = doc.allocate_node(node_element, "File");
        files->append_node(file);

        xml_node<> *path = doc.allocate_node(node_element, "Path","File_path");
        file->append_node(path);
        xml_node<> *name = doc.allocate_node(node_element, "Name""File_name");
        file->append_node(name);
    }

    std::ofstream myfile;
    myfile.open ("c:/example.xml");
    myfile << doc;
    //print(std::cout, doc, 0);
    return 0;
};
