蓋莫游戲引擎1.x版本是采用libxml操作xml文件的
這個庫弄得太復雜了
現在計劃從2.1.2開始使用rapidxml操作xml
首先上一個簡單的xml寫文件
如下:
#include <iostream>
#include <rapidxml/rapidxml.hpp>
#include <rapidxml/rapidxml_utils.hpp>
#include <rapidxml/rapidxml_print.hpp>
using namespace rapidxml;
int main()
{
xml_document<> doc;
xml_node<>* rot = doc.allocate_node(rapidxml::node_pi,doc.allocate_string("xml version='1.0' encoding='utf-8'"));
doc.append_node(rot);
xml_node<>* node = doc.allocate_node(node_element,"config","information");
xml_node<>* color = doc.allocate_node(node_element,"color",NULL);
doc.append_node(node);
node->append_node(color);
color->append_node(doc.allocate_node(node_element,"red","0.1"));
color->append_node(doc.allocate_node(node_element,"green","0.1"));
color->append_node(doc.allocate_node(node_element,"blue","0.1"));
color->append_node(doc.allocate_node(node_element,"alpha","1.0"));
xml_node<>* size = doc.allocate_node(node_element,"size",NULL);
size->append_node(doc.allocate_node(node_element,"x","640"));
size->append_node(doc.allocate_node(node_element,"y","480"));
node->append_node(size);
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("config.xml");
out << doc;
system("PAUSE");
return EXIT_SUCCESS;
}
生成的xml文件為:
<?xml version='1.0' encoding='utf-8' ?>
<config>
<color>
<red>0.1</red>
<green>0.1</green>
<blue>0.1</blue>
<alpha>1.0</alpha>
</color>
<size>
<x>640</x>
<y>480</y>
</size>
<mode fullscreen="false">screen mode</mode>
</config>
說實話 感覺這個比較不錯
希望更多的人使用它!
