我是在VC下编译运行。
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 //标志使用STL的内容
#define TIXML_USE_STL //标志使用STL的内容
6.然后创建一个cpp文件,输入下面的内容:
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include "tinyxml.h"
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
//原先代码是直接加载XML文件，我作了一下修改，把内容读到字符串后再解析，实际使用时就去掉读取XML文件这一步
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();
//////////////////////////////////////////////////////////////////////////
//这里开始从字符串中解析XML
//创建TiXmlDocument对象
TiXmlDocument* doc = new TiXmlDocument();
//解析
if(!doc->Parse(buffer))
{
cout << doc->ErrorDesc() << endl;
}
//获取根节点
const TiXmlElement* root = doc->RootElement();
//循环获取该根节点下面的节点
for( const TiXmlNode* child = root->FirstChild();
child;
child=child->NextSibling())
{
//判断为元素类型并且是staticbox元素，Value()获取该标签的名称
if((child->Type() == TiXmlNode::ELEMENT) && (!strcmp(child->Value(),"staticbox")))
{
const TiXmlElement *box = (const TiXmlElement*)child;
double px, py, pz;
double dx, dy, dz;
//获取属性值
std::string mesh;
mesh = box->Attribute("mesh");
//继续循环获取子节点相关数据
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;
}
else if(!strcmp(sub_tag->Value(),"test"))
{
//使用GetText()方法来获取该标签的值，如这里获取的是test的值1和2
string temp = sub_element->GetText();
}
}
}
cout << "<StaticBox>\n";
cout << "\tPosition = (" << px << ", " << py << ", " << pz << ")\n";
cout << "\tDimension = (" << dx << ", " << dy << ", " << dz << ")\n\n";
}
}
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" />
<test>1</test>
</staticbox>
<staticbox mesh="crate.mesh">
<position x="3" y="2" z="4" />
<dimension x="2" y="4" z="2" />
<test>2</test>
</staticbox>
</Scene>
8.编译运行
附另一个TinyXML读写XML的例子，此处写XML是直接写入XML文件，如果要使用这里的函数不写入文件而是组织成XML流，需要相应修改代码。代码在VS2005中测试运行成功。
#define TIXML_USE_STL //标志使用STL的内容
#include "stdafx.h"
#include <iostream>
#include <sstream>
#include <fstream>
#include "tinyxml.h"

WriteXML() ;
ReadXML() ;
ReadXML2() ;
cout << "结束测试!" << endl ;
return 0;
}
int WriteXML()
{
TiXmlDocument xmlDoc( "test.xml" ); // 建立一个XML文件

return 0 ;
