高分就教 xml问题！

我用ms xml写xml文档，用ue打开就只有一行，怎么在里面加上回车换行符号啊？谢谢！

appending "\n" or "\t" textnodes

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.4.0");
xmlDoc.async = false;


// preserveWhiteSpace is useful when loading
// existing documents.
xmlDoc.preserveWhiteSpace = true;
xmlDoc.appendChild(xmlDoc.createElement("root"));
xmlDoc.documentElement.appendChild(
xmlDoc.createTextNode("\r\n\t"));
xmlDoc.documentElement.appendChild(
xmlDoc.createElement("child"));
xmlDoc.documentElement.appendChild(
xmlDoc.createTextNode("\r\n"));
xmlDoc.save("test.xml");
you can also use MXXMLWriter and set its indent property

思路：在要换行的地方插入只有'\n'和'\t'的节点
BSTR bstr_wsn = SysAllocString(L"\n");
BSTR bstr_wsnt= SysAllocString(L"\n\t");
BSTR bstr_wsntt=SysAllocString(L"\n\t\t");

void AddWhiteSpaceToNode(IXMLDOMDocument* pDom,
BSTR bstrWs, //此参数是你要插入的回车或TAB又你自己定义，如上
IXMLDOMNode *pNode //pNode为要在之后插入TAB或回车的节点
)
{
HRESULT hr;
IXMLDOMText *pws=NULL;
IXMLDOMNode *pBuf=NULL;
HRCALL(pDom->createTextNode(bstrWs,&pws), " ");
HRCALL(pNode->appendChild(pws,&pBuf)," ");
clean:
if (pws) pws->Release();
pws=NULL;
if (pBuf) pBuf->Release();
pBuf=NULL;
}

IXMLDOMDocument *pXMLDom=NULL;
IXMLDOMProcessingInstruction *pi=NULL;
BSTR bstr = NULL;
BSTR bstr1 = NULL;
...

bstr = SysAllocString(L"xml");
bstr1 =SysAllocString(L"version='1.0' encoding='UTF-8'");
pXMLDom->createProcessingInstruction(bstr,bstr1, &pi);
AppendChildToParent(pi, pXMLDom);

上面掉了一个函数
void AppendChildToParent(IXMLDOMNode *pChild, IXMLDOMNode *pParent)
{
IXMLDOMNode *pNode=NULL;
pParent->appendChild(pChild, &pNode);
clean:
if (pNode) pNode->Release();
pNode=NULL;
}

也可以用此函数直接这样，不过用完最后都要释放的！
IXMLDOMDocument *pXMLDom=NULL;
IXMLDOMProcessingInstruction *pi=NULL;
IXMLDOMNode *pNode=NULL;
BSTR bstr = NULL;
BSTR bstr1 = NULL;
...

bstr = SysAllocString(L"xml");
bstr1 =SysAllocString(L"version='1.0' encoding='UTF-8'");
pXMLDom->createProcessingInstruction(bstr,bstr1, &pi);
pXMLDom->appendChild(pi,&pNode);

也可以不用此函数。呵呵写错了

在最前面加上<?xml version="1.0" encoding="UTF-8" ?>怎么加啊?
