This script shows you a reusable way to use "xml.parsers.expat" to parse an XML file. When re-using the "MyXML" class, all you need to define a new class, with "MyXML" as the parent. Once you have done that, all you have to do is overwrite the inherited XML handlers and you are ready to go.

HTML is the method of choice for those wishing to send emails with rich text, layout and graphics. Often it is desirable to embed the graphics within the message so recipients can display the message directly, without further downloads. Some mail agents don't support HTML or their users prefer to...
