VS2008 VC++ XML操作

VS2008 VC++ XML操作1.msxmlchs.msi的安装安装msxml 4.0 sp2时要注意不要用默认安装,要选择自定义安装（全部安装）才能选择安装SDK,若没有选择安装SDk会发现安装完成后安装目录下什么也没有,而选择了SDK的安装可以在目录下看到LIB INC doc 3个文件夹2.注册dll命令行输入如下命令可以弹出注册成功的对话框cd c:\windows\system32regsvr32 msxml4.dll (也可在运行框中直接输入这句)3.VS2008 设置工具->选项->项目和解决方案->VC++目录Include添加INC的的路径C:\Program Files\MSXML 4.0\INCLibrary添加INC的的路径C:\Program Files\MSXML 4.0\LIB4.VC60 设置Tools->Options... ->Directories tab->Include添加INC的的路径C:\Program Files\MSXML 4.0\INCTools->Options... ->Directories tab->Library添加INC的的路径C:\Program Files\MSXML 4.0\LIB5.新建项目，链接库代码中#include <msxml2.h>VC60 open Project Settings by clicking Settings from the Project menu. Select the Link tab.Append "msxml2.lib" to the Object/library modules: textbox.6.Code1://部分变量无法识别时在前面加命名空间MSXML2::#include<stdio.h>#import<msxml4.dll>using namespace MSXML2;int main(int argc, char* argv[]){MSXML2::IXMLDOMDocument2Ptr pXMLDom;HRESULT hr;CoInitialize(NULL);hr = pXMLDom.CreateInstance(__uuidof(DOMDocument40));if (FAILED(hr)){printf("Failed to CreateInstance on an XML DOM");return NULL;}pXMLDom->preserveWhiteSpace = VARIANT_TRUE;// Create a processing instruction targeted for xml.MSXML2::IXMLDOMProcessingInstructionPtr pi;pi = pXMLDom->createProcessingInstruction("xml", "version='1.0'");if (pi != NULL) {pXMLDom->appendChild(pi);pi.Release();}// Create a processing instruction targeted for xml-stylesheet.pi = pXMLDom->createProcessingInstruction("xml-stylesheet","type='text/xml' href='dom.xsl'");if (pi != NULL) {pXMLDom->appendChild(pi);pi.Release();}// Create a comment for the document.MSXML2::IXMLDOMCommentPtr pc;pc = pXMLDom->createComment("sample xml file created using XML DOM object.");
