请问各位，我使用msxml4.0和vc6，有以下几个问题
1）为什么使用TransformNodeToObject总是得不到正确的结果树，我参考的是msxml4
sdk中的例子，例子如下，
// p is the XML source that is to be transformed, pXSL is the style sheet.
// Create an empty DOM document for the result. (Error checking omitted
// for brevity.)
hr = CoCreateInstance(CLSID_DOMDocument40, NULL, CLSCTX_INPROC_SERVER,
IID_IXMLDOMDocument, (void**)&p);
hr = p->QueryInterface(IID_IDispatch, (void **)&pDisp);
vObject.vt = VT_DISPATCH; // the new object
vObject.pdispVal = pDisp;
hr = p->transformNodeToObject(pXSL, vObject); // Transformation is
// present in pDoc.
但是p->xml总是为空，也就是得不到xslt转化好的结果树。而我使用transformNode则可以得到xslt转化好的结果字符串。有高手是否可以帮忙解答？
2）xslt转化在客户端进行与在服务器端进行的比较（难度和时间比较），能否告诉？

2.
xslt转化在客户端进行: the client browser requirement is higher
xslt转化在服务器端进行: affects the scalability of the server
speed-wise, as long as the files are not big, the difference shouldn't be noticeable
