Description:

a tool to extract the rich text of some html 
(either a constructed tree, or from a parser).

Can be used to extract text (aka strings with emphasis) for display in
a tooltip or similar. 
Ignores everything, except <B>...</B> and <UL>..</UL>.

CAVEAT:
    I am not sure if this implementation is good enough for
    other uses in its current state 
    (maybe we have to look for specialities like PRE.../PRE or     
    text within form-elements to make this really correct).
