VERY GOOD thats works.
But some small hint / possible improvement

If you translate xhtml to ehtml with

  yaws_html:parse(Infile, Outfile)

the generated text file has no period at the end.

If you try to read the file again with

    {ok, [{ehtml, [Test]}]} = file:consult(Pfad2),

it crashes.

good to know

i am now 50 years old, up to now i was able to avoid emacs for 33 
years...VAX EDT was worse enough ;-), but maybe. I tried the eclipse erl 
plugin, but eclipse itself is a monster, so i went back to mc editor + git.
