' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Mime")
set mime = Server.CreateObject("Chilkat.Mime")

' The contents of this MIME file are shown below, 
' and is also available at https://www.chilkatsoft.com/sampleMime.txt
success = mime.LoadMimeFile("qa_data/mime/sampleMime.txt")
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( mime.LastErrorText) & "</pre>"
    Response.End
End If

' The MIME used in this example has the following nested structure
' 
' multipart/alternative
'     text/plain
'     multipart/related
'         text/html
'         image/jpeg
' 

' Convert to XML.
xmlStr = mime.GetXml()

' Load into a Chilkat XML object so we can emit in indented format.
' (and also to demonstrate how to access the MIME content from XML).
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Xml")
set xml = Server.CreateObject("Chilkat.Xml")
success = xml.LoadXml(xmlStr)
' The XML emitted by this statement is shown below, following the remainder of sample code.
Response.Write "<pre>" & Server.HTMLEncode( xml.GetXml()) & "</pre>"

' To get the top-level Subject header field:
Response.Write "<pre>" & Server.HTMLEncode( "Subject = " & xml.ChilkatPath("header|subject|*")) & "</pre>"

' Another way of getting the Subject:
success = xml.FirstChild2()
Response.Write "<pre>" & Server.HTMLEncode( "Subject = " & xml.GetChildContent("subject")) & "</pre>"
xml.GetRoot2 

' Using the Chilkat XML API, there are many different ways of accomplishing a goal.
' This example shows only a few possibilities...

' Let's go to the <body> tag containing the HTML.
' First we find the XML node where the content-type is text/html.
' (XML methods ending in "2" update the internal reference to the XML node.)
success = xml.SearchForContent2(xml,"content-type","text/html")
If (success = 1) Then
    ' From this point, we know the HTML content is two levels up (to the <mime_message> node),
    ' and one level down (to the <body> node).  We can get the HTML content from here:
    htmlContent = xml.ChilkatPath("..|..|body|*")
    Response.Write "<pre>" & Server.HTMLEncode( htmlContent) & "</pre>"
    Response.Write "<pre>" & Server.HTMLEncode( "-") & "</pre>"
End If

' Back to the root...
xml.GetRoot2 

' How to iterate over all image/jpeg bodies and access the bytes of each?
success = xml.SearchForContent2(xml,"content-type","image/jpeg")
Do While success = 1
    ' "$" in the Chilkat path indicates to update the internal reference of the caller
    ' if the path could be traversed.
    notUsed = xml.ChilkatPath("..|..|body|$")
    If (xml.LastMethodSuccess = 1) Then

        jpgBytes = xml.GetBinaryContent(0,0,"")

        Response.Write "<pre>" & Server.HTMLEncode( "Found JPG image!") & "</pre>"

        ' Find the next JPG image.
        success = xml.SearchForContent2(xml,"content-type","image/jpeg")
    Else
        success = 0
    End If
