ServerXMLHTTP.3.0 parsing problem

[=?Utf-8?B?SmFzb24=?=]

I'm using an ASP 3.0 page to query the USPS site for shipping rate info using
the ServerXMLHTTP.3.0 object. The code is as follows:

set objSrvHTTP = Server.CreateObject("Msxml2.ServerXMLHTTP.3.0")
objSrvHTTP.open "GET",
"http://production.shippingapis.com/ShippingAPI.dll?API=RateV2&XML=" &
xmlDoc.xml, False
objSrvHTTP.send

The request is successful, as indicated when I pretty print the resulting
response like this:

Response.ContentType = "text/xml"
Response.Write(objSrvHTTP.responseText)

The result is a well-formed XML document in the expected format. However,
when I try to parse the actual XML from objSrvHTTP.responseXML, I get
nothing. It's as if the XML doesn't exist. I also tried parsing
objSrvHTTP.responseXML.xml instead, but that didn't work either. I know the
XML response is being returned properly (as indicated when I pretty print the
responseText), but no matter what I try, I can't parse, print, or otherwise
access the actual XML! I'm hoping there's a simple solution to this, since
it's only a few lines of code but has been causing me no small amount of
frustration...

Thanks in advance,

Jason

Please check
objSrvHTTP.GetAllResponseHeaders()
to see whether the server sends the proper Content-Type header (e.g.
application/xml or text/xml) so that MSXML populates the responseXML
document.

Hi Martin,

The only result I get from
Response.Write(objSrvHTTP.GetAllResponseHeaders()) is this:

Server: Microsoft-IIS/5.0 Date: Thu, 31 May 2007 16:08:53 GMT
Connection: close

Do I need to use a different method to get the content-type header? As you
can see, I'm not very familiar with this server object. I did try explicitly
setting the content-type of the Response object to "text/xml", but that
didn't seem to have any effect.

Thanks for considering my problem, and further help would be greatly
appreciated.

The server you are making your request to needs to set the HTTP response
header
Content-Type: application/xml
so that MSXML populates the responseXML document.
If you can't change the server settings of that server then, if you want
a DOM document, you are left with e.g.
Set responseXML = CreateObject("Msxml2.DOMDocument.3.0")
responseXML.async = False
responseXML.load objSrvHTTP.responseStream

..responseStream was the key. I was already using an XML DOM document, but
was attempting to load it via the objSrvHTTP.responseXML. Thanks so much for
your help!
