Demonstrates how to insert any file into XML using base64 encoding, and then extract back to the original file. This example embeds a PDF in the XML, but the type of file does not matter. It can be any type of file. AutoIt

Local $bSuccess = False

; Load our PDF file.
$oBd = ObjCreate("Chilkat.BinData")
$bSuccess = $oBd.LoadFile("qa_data/helloWorld.pdf")

    ConsoleWrite("Failed to load PDF file." & @CRLF)
    Exit
EndIf

; Load the following XML:
; 
; <?xml version="1.0" encoding="utf-8" ?>
; <something>
;     <xyz>
;         <abc123>A base64 encoded PDF file will be inserted under this node.</abc123>

; Insert the PDF into the XML.
$oXml.NewChild2 "xyz|pdfData",$oBd.GetEncoded("base64")

; Show the new XML:
ConsoleWrite($oXml.GetXml() & @CRLF)

; The XML now looks like this:
; <?xml version="1.0" encoding="utf-8" ?>
; <something>
;     <xyz>
;         <abc123>A base64 encoded PDF file will be inserted under this node.</abc123>
;         <pdfData>JVBERi0xL ... UlRU9GCg==</pdfData>
;     </xyz>
; </something>

; To extract the PDF data out and restore the PDF file:
$oBd2 = ObjCreate("Chilkat.BinData")
$bSuccess = $oBd2.AppendEncoded($oXml.GetChildContent("xyz|pdfData"),"base64")
$bSuccess = $oBd2.WriteFile("qa_output/helloWorld.pdf")

ConsoleWrite("Success." & @CRLF)
