VC MSXML ADO简单读写

1. 导入MSXML.dll

#import "msxml3.dll"

using namespace MSXML2;

2. 创建实例

IXMLDOMDocumentPtr pXMLDoc; //XML文档

HRESULT hr = pXMLDoc.CreateInstance(__uuidof(MSXML2::DOMDocument30));

if (!SUCCEEDED(hr))

return FALSE;

3. 加入XML版本信息

IXMLDOMProcessingInstructionPtr pPi = pXMLDoc->createProcessingInstruction((_bstr_t)"xml", (_bstr_t)"version='1.0'");

if (pPi)pXMLDoc->appendChild(pPi);

4.创建节点,添加节点属性,插入节点

IXMLDOMElementPtrXMLColWidthNode = pXMLDoc->createElement((_bstr_t)"ColumnWidth");

if (XMLColWidthNode == NULL)

return FALSE;

((IXMLDOMElementPtr)XMLColWidthNode)->setAttribute((_bstr_t)"description", (_bstr_t)(LPCTSTR)"列宽设置");

XMLRootNode->appendChild(XMLColWidthNode);

5. 插入换行

IXMLDOMTextPtr XMLTextNode = pXMLDoc->createTextNode((_bstr_t)"\n\t\t");

XMLColWidthNode ->appendChild(XMLTextNode);

6. 保存文档

pXMLDoc->save((_bstr_t)(LPCTSTR)strFullPath);

7.导入文档

pXMLDoc->Load((_bstr_t)(LPCTSTR)strFullPath);

8. 转换为Text文本

_bstr_t bstrText = pXMLDoc->Getxml();

9. 导入Text文本

pXMLDoc->loadXML((_bstr_t)bstrText );

10.其他

GetchildNodes 获得所有子节点

GetnodeName 获取节点名称

Gettext 获得节点字符串
