Description:

Please read the Caveat & Warning in HTMLDocumentPainter.

An abstract class to walk through a list of HTML elements
(i.e. the document) and perform an action on each
(by sending self-messages named after the elements tag).

Not useful by its own, but provides a framework for
both HTML displayers and processors 
(i.e. must be subclassed).

 doesNotUnderstand: aMessage

(comment from inherited method)
this message is sent by the runtime system (VM) when
a message is not understood by some object (i.e. there
is no method for that selector). The original message has
been packed into aMessage (i.e. the receiver, selector and
any arguments) and the original receiver is then sent the
#doesNotUnderstand: message.
Here, we raise another signal which usually enters the debugger.
You can of course redefine #doesNotUnderstand: in your classes
to implement message delegation,
or handle the MessageNotUnderstood exception gracefully.

 processFrom: firstElement while: aBlock

process elements starting with firstElement, while aBlock
returns true. Should be called from a saveExcursion block.

 process: aDocument

 elementsDo: aBlock

enumerate the html elements

 elementsWithType: typeOrNil do: aBlock
