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

mime = Chilkat::CkMime.new()

success = mime.LoadMimeFile("qa_data/mime/sampleMime.txt")
if (success != true)
    print mime.lastErrorText() + "\n";
    exit
end

# Examine the structure in text format:
txtStruct = mime.getStructure("text")
print txtStruct + "\n";

# The MIME structure as indented text is:
# multipart/alternative
#     text/plain
#     multipart/related
#         text/html
#         image/jpeg
# 

# Now examine the structure in XML format:
xmlStruct = mime.getStructure("xml")
print xmlStruct + "\n";

# The MIME structure as XML is:
# <multipart-alternative>
#     <text-plain />
#     <multipart-related>
#         <text-html />
#         <image-jpeg />
#     </multipart-related>
# </multipart-alternative>
