set mime [new_CkMime]

set success [CkMime_LoadMimeFile $mime "qa_data/mime/sampleMime.txt"]
if {$success != 1} then {
    puts [CkMime_lastErrorText $mime]
    delete_CkMime $mime
    exit
}

# Examine the structure in text format:
set txtStruct [CkMime_getStructure $mime "text"]
puts "$txtStruct"

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

# Now examine the structure in XML format:
set xmlStruct [CkMime_getStructure $mime "xml"]
puts "$xmlStruct"

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