responseXML Property (ServerXMLHTTP/IServerXMLHTTPRequest)
Represents the response entity body as parsed by Microsoft® XML Core Services (MSXML).
For security reasons, the parser validation features are always turned off to prevent MSXML from attempting to download a document type definition (DTD) or XML-Data definition.
If the response entity body is not valid XML, this method returns the DOMDocument object that was parsed so that you can access the error object. This property does not return the error object IXMLDOMParseError itself. That object is accessible from the DOMDocument object.
If the response was generated by an Active Server Pages (ASP) page and the Multipurpose Internet Mail Extension (MIME) type was not correctly set to "text/xml" or "application/xml" using the ASP method Response.ContentType, responseXML will be empty.
