Demonstrates how to iterate over the email header fields.

Download Chilkat Ruby Library

require 'chilkat'

email = Chilkat::CkEmail.new()

#  First, load an email from a file.
#  Note: an email object may be loaded from a file, or
#  downloaded directly from a POP3 or IMAP server...

success = email.LoadEml("testReceivedHdrs.eml")
if (success != true)
    print email.lastErrorText() + "\n"
    exit
end

#  How many header fields?

n = email.NumHeaderFields()
if (n > 0)

    #  Display the name and value of each header:

    for i in 0 .. n - 1
        name = email.getHeaderFieldName(i)
        value = email.getHeaderFieldValue(i)
        print i.to_s() + "\n";
        print name + "\n";
        print value + "\n";

    end

end
