(MFC) Create MIME Containing XML

Calls SetBodyFromXml to load XML into the MIME body. Also sets the Content-Type header to "text/xml", and the Content-Transfer-Encoding to an appropriate transfer encoding based on the characters found in the XML.

void ChilkatSample(void)
    {
    CkString strOut;

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

    CkMime mime;

    // Add a few header fields:
    bool success = mime.AddHeaderField("Description","this is a test");
    success = mime.AddHeaderField("MyId","123");

    const char *xmlData = "<something>123</something>";

    // Set the mime body via SetBodyFromXml.  This also
    // has the intended side-effect of adding the Content-Type
    // and Content-Transfer-Encoding headers.
    success = mime.SetBodyFromXml(xmlData);

    strOut.append(mime.getMime());
    strOut.append("\r\n");

    // The MIME should look like this:

    // Description: this is a test
    // MyId: 123
    // Content-Type: text/xml; 
    // Content-Transfer-Encoding: 7bit
    // 
    // <something>123</something>

    // Note: The Content-Transfer-Encoding may be changed.
    // For example, to use "base64", do this:
    mime.put_Encoding("base64");

    // Show the MIME again, this time using the base64 
    // transfer encoding:
    strOut.append(mime.getMime());
    strOut.append("\r\n");

    // It should look like this:

    // Description: this is a test
    // MyId: 123
    // Content-Type: text/xml; 
    // Content-Transfer-Encoding: base64
    //
