bool success = false;

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

Chilkat.Mime mime = new Chilkat.Mime();

//  The contents of this MIME file are shown below, 
//  and is also available at https://www.chilkatsoft.com/sampleMime.txt
success = mime.LoadMimeFile("qa_data/mime/sampleMime.txt");
if (success != true) {
    Debug.WriteLine(mime.LastErrorText);
    return;
}

//  The MIME used in this example has the following nested structure
//  
//  multipart/alternative
//      text/plain
//      multipart/related
//          text/html
//          image/jpeg
//  

//  Convert to XML.
string xmlStr = mime.GetXml();

//  Load into a Chilkat XML object so we can emit in indented format.
//  (and also to demonstrate how to access the MIME content from XML).
Chilkat.Xml xml = new Chilkat.Xml();
xml.LoadXml(xmlStr);
//  The XML emitted by this statement is shown below, following the remainder of sample code.
Debug.WriteLine(xml.GetXml());

//  To get the top-level Subject header field:
Debug.WriteLine("Subject = " + xml.ChilkatPath("header|subject|*"));

//  Another way of getting the Subject:
xml.FirstChild2();
Debug.WriteLine("Subject = " + xml.GetChildContent("subject"));
xml.GetRoot2();

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

//  Let's go to the <body> tag containing the HTML.
//  First we find the XML node where the content-type is text/html.
//  (XML methods ending in "2" update the internal reference to the XML node.)
success = xml.SearchForContent2(xml,"content-type","text/html");
if (success == true) {
    //  From this point, we know the HTML content is two levels up (to the <mime_message> node),
    //  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?
success = xml.SearchForContent2(xml,"content-type","image/jpeg");
while (success == true) {
    //  "$" in the Chilkat path indicates to update the internal reference of the caller
    //  if the path could be traversed.
    string notUsed = xml.ChilkatPath("..|..|body|$");
    if (xml.LastMethodSuccess == true) {
        byte[] jpgBytes = null;
        jpgBytes = xml.GetBinaryContent(false,false,"");

        Debug.WriteLine("Found JPG image!");

        //  Find the next JPG image.
        success = xml.SearchForContent2(xml,"content-type","image/jpeg");
    }
    else {
        success = false;
    }
