Any source of Plain-text stylesheets?

[Tommy Nordgren <tommy.nordgren@comhem.se>]

I need to find docbook stylesheets that can strip off xml markup, as  
well as any content that is not plaintext.
Do someone on this list know of any such source.
Alternately, do some one know of any grammar checker for the english  
language, hosted on Mac OS X,
that retains xml markup.
