[tex4ht] htlatex and docbook

[philippe]

Hi,

i work with MikTeX 2.9 on windows7 i use to convert from latex to 
html+css with htlatex but i need now to produce docbook   from my latex 
files, so I've tried the command

htlatex --dtd=docbook fichier.tex

but it doesn't work. It seems that option "--dtd=docbook" is not 
recognized ( I get a message like " try another file name" ?!?) I have 
also eared about "htrun" but I have not found "htrun" in MiKTeX2.9.

Does any one knows something about this ?

Philippe.
