How to read the XML data returned from an API with VB Script?

I am trying to learn a bit more about VB scripting, as well as better understand how a client would use a simple API I have parked at a web site I own and have hosted at a cloud server.  I can successfully access the URL (no credentials needed at this point) and properly submit the requested fields and operand.  What comes back is a bunch of API text to my monitor.  I need to know how to capture the stream without it being displayed, and then use the saved page of XML lines as TXT so that I can have my script then pick off what I want and present it in a MSGBOX.

Here is what successfully accesses it:

  Set oShell = CreateObject("Wscript.Shell")
  oShell.Exec "C:\Program Files\Internet Explorer\iexplore.exe https://api.niftywebsite.net/?opts=WORD1&whatiwant=123456"

Here is what I get back in my browser:

<?xml version="1.0" encoding="UTF-8"?>
-<response>
-<entity>
<whatiwant>123456</whatiwant>
<WORD1>Just some test stuff</WORDS1>
</entity>
</response>

So can I suppress the monitor echo and pipe the XML text to a file?  Better would be if I could just hold the text and access it without a file save / open / read.

I would use the HTTP object and the xml Dom Document to get the values and parse them.

Something like this:

Dim objHttp, objXMLDoc

Set objHttp = CreateObject("MSXML2.ServerXMLHTTP.6.0")
Set objXMLDoc = CreateObject("Msxml2.DOMDocument") 

With objHttp
	.Open "GET", "https://api.niftywebsite.net/?opts=WORD1&whatiwant=123456"
	.Send
	objXMLDoc.LoadXML .responseText
End With

msgbox objXMLDoc.SelectSingleNode("//whatiwant").text

set objHttp = nothing
set objXMLDoc = nothing

Perfect!  Exactly what I was looking for.  I frankly don't understand all of the code, but I'll let Mr. Google teach me the details.  Thanks so much.
