Thanks a lot for your answer. This week end I will:
1. look up a wikipedia article on xml and work my way to understanding what it is from there with reference articles...
2. download the OO SDK, look at the documentation and try to gather what it takes to "develop" something for OO
3. look at the code of the plugins already written
4. post here a template of what a complete html code would look like

Maybe by then you'll be able to help me further too !

Thanks
