This example demonstrates how to extract files from a binary SOAP MTOM MIME document. Chilkat2 Perl

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

my $mime = Chilkat2::Mime->new;

# 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
#

my $success = $mime->LoadMimeFile('qa_data/mime/headless_binary_soap_mtom_mime.mim');

    print $mime->LastErrorText, "\n";
