我是在VC下編譯運行。
2.下載後解壓這個壓縮包,把所有的東西放到一個找的着的地方(比如,E:/開發庫/TinyXML)
3.用Visual C++(推薦VC++.NET2003)創建一個新的工程(Win32控制檯)
4.在TinyXML的目錄裏面找到tinystr.h, tinyxml.h, tinystr.cpp, tinyxml.cpp, tinyxmlerror.cpp, tinyxmlparser.cpp六個文件加入到剛剛創建的項目中去
5.打開tinyxml.h, 在第一行加入下面這行:
#define TIXML_USE_STL //標誌使用STL的內容
#define TIXML_USE_STL //標誌使用STL的內容
6.然後創建一個cpp文件,輸入下面的內容:
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include "tinyxml.h"
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
//原先代碼是直接加載XML文件，我作了一下修改，把內容讀到字符串後再解析，實際使用時就去掉讀取XML文件這一步
string filename = "first.xml";
//TiXmlDocument* doc = new TiXmlDocument(filename.c_str());
//////////////////////////////////////////////////////////////////////////
// 在這裏複製文件
//////////////////////////////////////////////////////////////////////////
std::ifstream ifs(filename.c_str());
char buffer[1024];
char c, *p = buffer;
while(ifs.get(c))
{
*p++=c;
}
*p = 0;
ifs.close();
//////////////////////////////////////////////////////////////////////////
//這裏開始從字符串中解析XML
//創建TiXmlDocument對象
TiXmlDocument* doc = new TiXmlDocument();
//解析
if(!doc->Parse(buffer))
{
cout << doc->ErrorDesc() << endl;
}
//獲取根節點
const TiXmlElement* root = doc->RootElement();
//循環獲取該根節點下面的節點
for( const TiXmlNode* child = root->FirstChild();
child;
child=child->NextSibling())
{
//判斷爲元素類型並且是staticbox元素，Value()獲取該標籤的名稱
if((child->Type() == TiXmlNode::ELEMENT) && (!strcmp(child->Value(),"staticbox")))
{
const TiXmlElement *box = (const TiXmlElement*)child;
double px, py, pz;
double dx, dy, dz;
//獲取屬性值
std::string mesh;
mesh = box->Attribute("mesh");
//繼續循環獲取子節點相關數據
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()方法來獲取該標籤的值，如這裏獲取的是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.然後在項目的文件夾中加入一個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.編譯運行
附另一個TinyXML讀寫XML的例子，此處寫XML是直接寫入XML文件，如果要使用這裏的函數不寫入文件而是組織成XML流，需要相應修改代碼。代碼在VS2005中測試運行成功。
#define TIXML_USE_STL //標誌使用STL的內容
#include "stdafx.h"
#include <iostream>
#include <sstream>
#include <fstream>
#include "tinyxml.h"
using namespace std;
int WriteXML() ;
int ReadXML() ;
//讀取內存裏的一段XML
int ReadXML2() ;
int _tmain(int argc, _TCHAR* argv[])
{
cout << "開始測試!" <<endl;
WriteXML() ;
ReadXML() ;
ReadXML2() ;
cout << "結束測試!" << endl ;
return 0;
}
int WriteXML()
{
TiXmlDocument xmlDoc( "test.xml" ); // 建立一個XML文件
TiXmlDeclaration Declaration( "1.0","gb2312", "yes" ); // 聲明XML的屬性
xmlDoc.InsertEndChild( Declaration ); // 寫入基本的XML頭結構
TiXmlNode * pNode = NULL;
TiXmlElement* pRootElm = NULL;
TiXmlElement* pChildeElm = NULL;
TiXmlElement* pItemElm = NULL;
TiXmlText* pText = NULL; // 一個指向Text的指針
pText = new TiXmlText("good") ;
pRootElm = new TiXmlElement( "todo" );
pNode = xmlDoc.InsertEndChild(*pRootElm) ;
pRootElm = pNode->ToElement() ;
pChildeElm = new TiXmlElement("child1") ;
pChildeElm->SetAttribute("num", 9) ;
pNode = pRootElm->InsertEndChild(*pChildeElm) ;

pChildeElm->SetAttribute("num", 10) ;
pNode = pRootElm->InsertBeforeChild (pChildeElm1, *pChildeElm) ;
TiXmlElement* pChildeElm2 = NULL;
pChildeElm2 = pNode->ToElement() ;
pChildeElm2->InsertEndChild(*pText) ;
xmlDoc.Print() ;
xmlDoc.SaveFile(); // 把XML文件寫入硬盤
return 0 ;
}
int ReadXML()
{
cout<<endl ;
cout<<"開始read XML"<<endl ;
