OpenOffice.org DocBook Filters

Hi

I'm trying to convert soffice to DocBook
with reffering an instruction, but it's not worked.
http://xml.openoffice.org/xmerge/docbook/

If someone have tried to convert DocBook from soffice,
I hope them to let me have more actual information.
Following is my test env.

OS            : Windows XP SP2
OpenOffice : 1.1.4

Any comments would be very appreciated.
