源码如下：
CoInitialize(NULL);
// 创建文档
MSXML2::IXMLDOMDocument2Ptr pXMLDoc = NULL;
//创建DOMDocument对象
HRESULT hr = pXMLDoc.CreateInstance(__uuidof(MSXML2::DOMDocument));
if (!SUCCEEDED(hr))
{
AfxMessageBox("==1");
return;
}
// Create the Processing Instruction
MSXML2::IXMLDOMProcessingInstructionPtr pXMLProc = NULL;
pXMLProc = pXMLDoc->createProcessingInstruction("xml", "version='1.0' encoding='UTF-8'");
_variant_t vNullVal;
vNullVal.vt = VT_NULL;
pXMLDoc->insertBefore(pXMLProc, vNullVal);
// 创建根结点
_variant_t varNodeType((short)MSXML2::NODE_ELEMENT);
MSXML2::IXMLDOMNodePtr pXMLNodeRoot= NULL;
pXMLNodeRoot = pXMLDoc->createNode(varNodeType, _T("Cases"), _T(""));
// 添加根结点
pXMLDoc->appendChild(pXMLNodeRoot);
// 创建并添加下级结点
MSXML2::IXMLDOMNodePtr pXMLNodeNode= NULL;
pXMLNodeNode = pXMLNodeRoot->appendChild(pXMLDoc->createElement(_T("Case")));
// 创建下级元素结点
MSXML2::IXMLDOMElementPtr pXMLEle = NULL;
pXMLEle = pXMLDoc->createElement(_T("CopyFile"));
// 创建并设置下级结点属性
MSXML2::IXMLDOMAttributePtr pXMLAttr = NULL;
pXMLAttr = pXMLDoc->createAttribute(_T("src"));
pXMLAttr->nodeTypedValue = "C:\test.txt";
pXMLEle->attributes->setNamedItem(pXMLAttr);
pXMLAttr = pXMLDoc->createAttribute(_T("dest"));
pXMLAttr->nodeTypedValue = "D:\Test.txt";
pXMLEle->attributes->setNamedItem(pXMLAttr);
// 添加元素结点
pXMLNodeNode->appendChild( pXMLEle);
MSXML2::IXMLDOMElementPtr pXMLEle1 = NULL;
pXMLEle1 = pXMLDoc->createElement(_T("DelFile"));
pXMLEle1->appendChild(pXMLDoc->createTextNode("C:\test.txt"));
// 添加元素结点
pXMLNodeNode->appendChild( pXMLEle1);
// 保存文档
pXMLDoc->save(_T("\Test.xml"));
问题：生成的Test.xml中的信息用 记事本 或者 UltraEdit 打开 是在一行显示的，如下：
