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

loMime = CreateObject('Chilkat.Mime')

lnSuccess = loMime.LoadMimeFile("qa_data/mime/sampleMime.txt")
IF (lnSuccess <> 1) THEN
    ? loMime.LastErrorText
    RELEASE loMime
    CANCEL
ENDIF

* Examine the structure in text format:
lcTxtStruct = loMime.GetStructure("text")
? lcTxtStruct

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

* Now examine the structure in XML format:
lcXmlStruct = loMime.GetStructure("xml")
? lcXmlStruct

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