Pascal (Lazarus/Delphi)

Create MIME Containing XML

See more MIME Examples

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. Pascal (Lazarus/Delphi)

  success := mime.AddHeaderField('MyId','123');

  //  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);

  WriteLn(mime.GetMime());

  //  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.Encoding := 'base64';

  //  Show the MIME again, this time using the base64 
  //  transfer encoding:
  WriteLn(mime.GetMime());

  //  It should look like this:

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