Extract Files from Binary SOAP MTOM MIME

See more MIME Examples

This example demonstrates how to extract files from a binary SOAP MTOM MIME document. PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

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

$mime = New-Object Chilkat.Mime

# In this example, we have a MIME file containing 8bit (non-encoded) binary data,
# and it is what I call "headless".  MIME is headless when it omits
# the top-level header.  The file we have here begins with the first
# boundary string.

# The structure the MIME to be loaded is:

# multipart/mixed (inferred because it is headless)
#     application/xop+xml
#     image/jpeg
#     image/gif
#     image/gif
# 

$success = $mime.LoadMimeFile("qa_data/mime/headless_binary_soap_mtom_mime.mim")
if ($success -eq $false) {
    $($mime.LastErrorText)
    exit
}

# The MIME file loaded in this example contains this:
