validating xml by variable dtd

[DP]

I am requesting xml from a url. Now I want to validate this xml by a
dtd. Is it possible that i define a dtd afterwards instead of in the
xml itself? I don't like to bother the users wich provide me this url
with a dtd tag in top of the document en also things can go wrong
here.
I also want to validate different url's by different dtd wich i want
to define myself
'CODE-------------------------------------------------------------

dim xmlHTTP, xmlDomObj, xmlData
set xmlHTTP = CreateObject("Msxml2.ServerXMLHTTP.3.0")
xmlHTTP.open "POST", requestURL, False
xmlHTTP.send

' parse requested xml and make it managable via DOM
set xmlDomObj = server.CreateObject("MSXML2.DOMDocument")
xmlData = xmlHTTP.responsetext
xmlDomObj.async = true
xmlDomObj.loadXML (xmlData)
' ---??DEFINE DTD HERE?

' check if during parsing any errors were encountered
if xmlDomObj.parseError.errorCode <> 0 then
call errorOccured("Error parsing XML (error " &
xmlDomObj.parseError.errorCode & "): " & xmlDomObj.parseError.reason &
" at line " & xmlDomObj.parseError.line & " character " &
xmlDomObj.parseError.linepos & "<BR><a href=""" & requestURL & """>XML
Source</a><BR>Probably url is not returning valid xml",
"xml_handler->getXMLviaURL")
set getXMLDocument = Nothing
set getXMLviaURL = nothing
else
' return xml Dom Object object
set getXMLviaURL = xmlDomObj
end if

Not with a DTD, MSXML 4 has W3C schema support and there the schema can
be external and not referenced in the XML instance itself so script can
load a schema separately before parsing/validating the XML instance.
I also want to validate different url's by different dtd wich i want
to define myself

Msxml does the 'parse and make manabable via DOM' for you automatically
so the lines below are not necessary, you can simply set
set xmlDomObj = xmlHTTP.responseXML
set xmlDomObj = server.CreateObject("MSXML2.DOMDocument")
xmlData = xmlHTTP.responsetext
xmlDomObj.async = true
xmlDomObj.loadXML (xmlData)
