Local $bSuccess
$oHttp = ObjCreate("Chilkat.Http")

$oReq = ObjCreate("Chilkat.HttpRequest")

; ...
; Insert code here to construct some kind of HTTP request.
; this example is to show how to parse a particular kind of response.
; ...
; ...

; Send the request (whatever it may be in your case) to get the HTTP response object.
Local $oResp = $oHttp.SynchronousRequest("www.somedomain.com",443,True,$oReq)
If ($oHttp.LastMethodSuccess <> True) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

; Get the response body (which is expected to be binary)
$oRespBody = ObjCreate("Chilkat.BinData")
$oResp.GetBodyBd($oRespBody)

; For this example, the response body contains something like this:

; ------=_Part_21302_2029949381.1547401515443
; Content-Type: application/xop+xml; charset=UTF-8; type="text/xml"
; Content-Transfer-Encoding: 8bit
; Content-ID: <rootpart@ws.jboss.org>
; 
; <env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'><env:Header></env:Header><env:Body>...</env:Body></env:Envelope>
; ------=_Part_21302_2029949381.1547401515443
; Content-Type: application/octet-stream
; Content-Transfer-Encoding: binary
; Content-Id: <fileArchivio-7d302908-4d64-43d3-bf4e-79ce806d43b3@ws.jboss.org>
; 
; BINARY_CONTENT_HERE...
; 
; ------=_Part_21302_2029949381.1547401515443--
; 

; Load it into a Chilkat MIME object.
$oMime = ObjCreate("Chilkat.Mime")
$bSuccess = $oMime.LoadMimeBd($oRespBody)
If ($bSuccess <> True) Then
    ConsoleWrite($oMime.LastErrorText & @CRLF)
    Exit
EndIf

Local $iNumParts = $oMime.NumParts
If ($iNumParts < 2) Then
    ConsoleWrite("Expected multipart MIME with at least 2 sub-parts." & @CRLF)
    Exit
EndIf

; Get the 1st sub-part, which is the XML.
Local $oPart0 = $oMime.GetPart(0)
; Should be OK because we checked NumParts above..
Local $sXmlStr = $oPart0.GetBodyDecoded()
ConsoleWrite($sXmlStr & @CRLF)
ConsoleWrite("----" & @CRLF)

; Save the 2nd part to a file.  (It is a .zip file in our test case..)
Local $oPart1 = $oMime.GetPart(1)
$bSuccess = $oPart1.SaveBody("qa_output/attachedZip.zip")

; Alternatively, we could extract the binary data to a BinData and use elsewhere..
$oZipData = ObjCreate("Chilkat.BinData")
$bSuccess = $oPart1.GetBodyBd($oZipData)
$bSuccess = $oZipData.WriteFile("qa_output/attachedZip_again.zip")

ConsoleWrite("OK." & @CRLF)
