怎么使用XMLDOMDocument生成一段xml代码?

怎么使用XMLDOMDocument生成一段xml代码?

1.
BOOL CXmlApp::InitInstance()
{
AfxOleInit();
...
}

2.
#import

3.
void CXmlDlg::OnButton1()
{
// TODO: Add your control notification handler code here

MSXML2::IXMLDOMDocumentPtr pDoc;
MSXML2::IXMLDOMElementPtr xmlRoot ;

//创建DOMDocument对象
HRESULT hr = pDoc.CreateInstance(__uuidof(MSXML2::DOMDocument30));
if(!SUCCEEDED(hr))
{
MessageBox("无法创建DOMDocument对象，请检查是否安装了MS XML Parser 运行库!");
}

//根节点的名称为china
pDoc->raw_createElement((_bstr_t)(char*)"china", &xmlRoot);
pDoc->raw_appendChild(xmlRoot, NULL);

MSXML2::IXMLDOMElementPtr childNode ;
pDoc->raw_createElement((_bstr_t)(char*)"City", &childNode);
childNode->Puttext("WuHan");//节点值
childNode->setAttribute("population","8,000,000");//属性名,属性值
childNode->setAttribute("area","10000");
xmlRoot->appendChild(childNode);

pDoc->raw_createElement((_bstr_t)(char*)"City", &childNode);
childNode->Puttext("ShangHai");
childNode->setAttribute("population","12,000,000");
childNode->setAttribute("area","12000");
xmlRoot->appendChild(childNode);

//保存到文件
//如果不存在就建立,存在就覆盖
pDoc->save("f:\he.xml");

}

生成的he.xml如下:

WuHanShangHai

---------------还有个例子
#include "stdafx.h"

#include "iostream.h"

#include "msxml.h"

#include "atlbase.h"

#import "msxml.dll" //引入类型库

#ifdef _DEBUG

#define new DEBUG_NEW

#undef THIS_FILE

static char THIS_FILE[] = __FILE__;

#endif

int Exit();

void LoadFromString();

void CreateXML();

//XML文本模板

_bstr_t XMLTemple=" -11 9 ";

int main()

{

cout << " XML编程--示范程序 " << endl;

CoInitialize(NULL); //初始化COM 环境

cout << "------生成新的XML文本 ------" << endl;

CreateXML();

cout << "------读取已有XML文本 ------" << endl;

LoadFromString();

return Exit();

}

void CreateXML()

{

MSXML::IXMLDOMDocumentPtr pDoc;

HRESULT hr =pDoc.CreateInstance(__uuidof(MSXML::DOMDocument));

if(!SUCCEEDED(hr))

{

cout << "无法创建DOMDocument对象，请检查是否安装了MS XML Parser 运行库!" << endl;

Exit();

}

MSXML::IXMLDOMElementPtr pDocElement=pDoc->createElement("China");

pDoc->appendChild(pDocElement);

cout << "生成树根：\n" << pDoc->xml << endl;

MSXML::IXMLDOMElementPtr pNewChildElement;

pNewChildElement=pDoc->createElement("Beijing");

pNewChildElement->Puttext("-11");

pDocElement->appendChild(pNewChildElement);

cout << "添加节点：\n" << pDoc->xml << endl;

pNewChildElement=pDoc->createElement("Shanghai");

pNewChildElement->Puttext("9");

pNewChildElement->setAttribute("Weather",_variant_t("Cloudy"));

pDocElement->appendChild(pNewChildElement);

cout << "再添加节点：\n" << pDoc->xml << endl;

pDocElement->removeChild (pNewChildElement);

cout << "把刚加入的节点删除：\n" << pDoc->xml << endl;

}

void LoadFromString()

{

MSXML::IXMLDOMDocumentPtr pDoc;

HRESULT hr =pDoc.CreateInstance(__uuidof(MSXML::DOMDocument));

if(!SUCCEEDED(hr))

{

cout << "无法创建DOMDocument对象，请检查是否安装了MS XML Parser 运行库!" << endl;

Exit();

}

pDoc->loadXML(XMLTemple);

cout << "读取结果：\n" << pDoc->xml << endl;

MSXML::IXMLDOMElementPtr pDocElement=pDoc->GetdocumentElement();

MSXML::IXMLDOMElementPtr pElement=pDocElement->selectSingleNode("Shanghai");

pDocElement->removeChild(pElement);

cout << "定位删除Shanghai节点：\n" << pDoc->xml << endl;

cout << "保存结果 Save .....(模拟而已)" << endl;

cout << "\n 好了，就这么简单" << endl;

}

int Exit()

{

getchar();

return 1;

}
