Vb-script parse webpages with username and password - vbscript

Question

NOTE: I need to use something like Vb-Script or batch because that is what i am familiar with and i also need to be able to run, edit, and create files.
I need to name MS Word files values on a webpage. I decided to first download the webpage as HTML using this code:
function download(sFileURL, sLocation, async)
set objXMLHTTP = CreateObject("MSXML2.XMLHTTP")
objXMLHTTP.open "GET", sFileURL, async
on error resume next
objXMLHTTP.send()
if err.number = 0 then
do until objXMLHTTP.Status = 200
wscript.echo objXMLHTTP.Status
wcript.sleep(200)
loop
if objXMLHTTP.Status = 200 Then
set objADOStream = CreateObject("ADODB.Stream")
objADOStream.Open
objADOStream.Type = 1
objADOStream.Write objXMLHTTP.ResponseBody
objADOStream.Position = 0
set objFSO = Createobject("Scripting.FileSystemObject")
If objFSO.Fileexists(sLocation) Then objFSO.DeleteFile sLocation
Set objFSO = Nothing
objADOStream.SaveToFile sLocation
objADOStream.Close
set objADOStream = Nothing
download = true
end if
else
download = false
end if
set objXMLHTTP = Nothing
end function
if download("https://web.example.com\login.php", "C:\", false) then
wscript.echo "download ok"
else
wscript.echo "download nok"
end if
The only problem is that to view this page you need to be logged in with a username and password.
NOTE: I can't use the actual webpage for security reasons.
