Pascal (Lazarus/Delphi)

Load MIME from a String

Demonstrates the Chilkat Mime.LoadMime method, which parses complete MIME text and replaces the current object's headers, body, and multipart tree. The only argument is the MIME string.

Background: MIME is the structure behind email messages and many other content containers — a set of headers, a blank line, then a body that may itself be a tree of nested parts. Loading parses that text into an object you can then inspect and modify part by part. A successful load fully replaces whatever the object held before, and Chilkat is tolerant of common real-world formatting quirks. When the content may contain raw 8-bit or NUL bytes, prefer LoadMimeBd so nothing is forced through a text string.
