// multipart/alternative
// text/plain
// multipart/related
// text/html
// image/jpeg

// Convert to XML.

// (and also to demonstrate how to access the MIME content from XML).

// Using the Chilkat XML API, there are many different ways of accomplishing a goal.
// This example shows only a few possibilities...

// and one level down (to the <body> node). We can get the HTML content from here:
string htmlContent = xml.ChilkatPath("..|..|body|*");
Debug.WriteLine(htmlContent);
Debug.WriteLine("-");
}
// Back to the root...
xml.GetRoot2();
// How to iterate over all image/jpeg bodies and access the bytes of each?

// "$" in the Chilkat path indicates to update the internal reference of the caller
// if the path could be traversed.
