#include "xhtml_doc.h"
#include <iostream>
int main(int argc, char* argv[])
{
using namespace Xport;
stylesheet ss;
stylesheet::iterator it = ss.insert(stylesheet_rule("html"));
it->insert(declaration(css::margin, "5px"));
it->insert(declaration(css::padding, "5px"));
it->insert(declaration(font_family, "Tahoma"));
it = ss.insert(stylesheet_rule("#sidebar"));
it->insert(declaration(css::position, "absolute"));
it->insert(declaration(css::right, "5px"));
it->insert(declaration(css::top, "10px"));
it->insert(declaration(css::width, "100px"));
it = ss.begin();
std::cout << "The html rule has " << it->size() << " declarations.\n";
++it;
std::cout << "The #sidebar rule has " << it->size() << " declarations.\n\n";
std::cout << "Clearing the declarations from both rules.\n\n";
it->clear();
--it;
it->clear();
std::cout << "The html rule now has " << it->size() << " declarations.\n";
++it;
std::cout << "The #sidebar rule now has " << it->size() << " declarations.\n\n";
}
