Hi, This looks nice.. We are already using JTidy for the HTML -> XHTML conversion before we export to PDF. A good way to do this is indeed as an XWiki plugin. I would suggest 2 plugins: 1/ Importer It would be great if the importer have a generic part and a format specific part. We could use the base code as the code to import from other wiki formats. There is one case which is complex in importing is when you want to handle links. You might need to read multiple files to convert links from one format to another. For example if you have a set of HTML files with relative links you might want to convert them to wiki links. An importer framework which allows to handle this would be great. 2/ Validator/Cleaner It would be great to be able to use each part separately and have some options when calling it. Besides cross side scripting being able to allow/refuse tag lists would be great and also allow/refuse velocity and groovy I guess Vincent would like to see the plugin outside of the core, but I'll leave this to him.
