1.首先下载TinyXML库的文件,这里给出链接,大家自己去下吧,记着要上国际
http://prdownloads.sourceforge.net/tinyxml/tinyxml_2_3_4.zip?download
2.下载后解压这个压缩包,把所有的东西放到一个找的着的地方(比如,E:开发库TinyXML)
3.用Visual C++(推荐VC++.NET2003)创建一个新的工程(Win32控制台)
4.在TinyXML的目录里面找到tinystr.h, tinyxml.h, tinystr.cpp, tinyxml.cpp, tinyxmlerror.cpp, tinyxmlparser.cpp六个文件加入到刚刚创建的项目中去
5.打开tinyxml.h, 在第一行加入下面这行:
#define TIXML_USE_STL
6.然后创建一个cpp文件,输入下面的内容:
1. #include <iostream>
#include <fstream>
#include "tinyxml.h"
using namespace std;
int main()
{
string filename = "first.xml";
TiXmlDocument* doc = new TiXmlDocument(filename.c_str());
//////////////////////////////////////////////////////////////////////////
// 在这里复制文件
//////////////////////////////////////////////////////////////////////////
std::ifstream ifs(filename.c_str());
char buffer[1024];
char c, *p = buffer;
while(ifs.get(c))
{
*p++=c;
}
*p = 0;
ifs.close();
//////////////////////////////////////////////////////////////////////////
if(!doc->Parse(buffer))
{
cout << doc->ErrorDesc() << endl;
}
const TiXmlElement* root = doc->RootElement();
for( const TiXmlNode* child = root->FirstChild();
child;
child=child->NextSibling())
{
OutputDebugStringA(child->Value());
/*
生成一个StaticBox
<staticbox mesh="crate.mesh">
<position x="-8" y="2" z="4" />
<dimension x="2" y="4" z="2" />
</staticbox>
*/
if((child->Type() == TiXmlNode::ELEMENT) && (!strcmp(child->Value(),"staticbox")))
{
const TiXmlElement *box = (const TiXmlElement*)child;
double px, py, pz;
double dx, dy, dz;
std::string mesh;
mesh = box->Attribute("mesh");
for(const TiXmlNode *sub_tag = box->FirstChild(); sub_tag; sub_tag = sub_tag->NextSibling() )
{
if(sub_tag->Type() == TiXmlNode::ELEMENT)
{
const TiXmlElement *sub_element = (const TiXmlElement*)sub_tag;
if(!strcmp(sub_tag->Value(),"position"))
{
px = (sub_element->Attribute("x",&px))?px:0.0;
py = (sub_element->Attribute("y",&py))?py:0.0;
pz = (sub_element->Attribute("z",&pz))?pz:0.0;
}
else if(!strcmp(sub_tag->Value(),"dimension"))
{
dx = (sub_element->Attribute("x",&dx))?dx:1.0;
dy = (sub_element->Attribute("y",&dy))?dy:1.0;
dz = (sub_element->Attribute("z",&dz))?dz:1.0;
}
}
}
cout << "<StaticBox>
";
cout << " Position = (" << px << ", " << py << ", " << pz << ")
";
cout << " Dimension = (" << dx << ", " << dy << ", " << dz << ")
";
}
}
delete doc;
getchar();
return 0;
}
7.然后在项目的文件夹中加入一个xml文件,如下:
<?xml version="1.0" encoding="utf-8" ?>
<Scene>
<staticbox mesh="crate.mesh">
<position x="-8" y="2" z="4" />
<dimension x="2" y="4" z="2" />
</staticbox>
<staticbox mesh="crate.mesh">
<position x="3" y="2" z="4" />
<dimension x="2" y="4" z="2" />
</staticbox>
</Scene>
8.编译运行
