我使用VS2015/VC++来建立一个XML文件，首先引入了msxml6, 然后参考了微软的示例代码如下:

import "msxml6.dll" using namespace MSXML2;

主循环里的代码如下:

MSXML2::IXMLDOMDocumentPtr pXMLDom; HRESULT hr = pXMLDom.CreateInstance(__uuidof(MSXML2::DOMDocument60), NULL, CLSCTX_INPROC_SERVER); if (FAILED(hr)) { printf("Failed to instantiate an XML DOM.\n"); return; } try { pXMLDom->async = VARIANT_FALSE; pXMLDom->validateOnParse = VARIANT_FALSE; pXMLDom->resolveExternals = VARIANT_FALSE; pXMLDom->preserveWhiteSpace = VARIANT_TRUE; // Create a processing instruction targeted for xml. MSXML2::IXMLDOMProcessingInstructionPtr pi = pXMLDom->createProcessingInstruction(L"xml", L"version='1.0'"); **pXMLDom->appendChild(pi);** // Create a comment for the document. MSXML2::IXMLDOMCommentPtr pc = pXMLDom->createComment(L"sample xml file created using XML DOM object."); **pXMLDom->appendChild(pc);** ...... }

但是VS2015总是报class "MSXML2::IXMLDOMDocument" 没有成员 "appendChild". 编译是也是报错，网上查夜查不到答案。有没有人知道为什么?
