You're right. I checked the test case for msxml3.dll, and modified my code to:

    hres = IXMLDOMDocument_loadXML(xmldoc, str, &vbool);
    if(vbool != VARIANT_TRUE) {
        ERR("loadXML(%s) failed: %08x\n", debugstr_w(str), hres);
        IXMLDOMDocument_Release(xmldoc);
        SysFreeString(str);
        return hres;
    }
    SysFreeString(str);

Sorry, I'm not sure the meaning of "trace xml"
If loadXML() fails, I think the terminal output should provide verbose
information
