Hi Vincent, 1) add props.setPruneTags("script, style"); in DefaultHTMLCleaner. This will remove all the script and style tags and their contents. script and style tags are useless for the later use, IMO. 2) remove the first p tag following th li tag. <ul> <li><p>test</p></li> </ul> could not render properly in xwiki syntax 1.0 and xhtmlparser+xwikisyntaxrendering. It should change to <ul> <li>test</li> </ul> I have a filter with w3c dom: http://svn.xwiki.org/svnroot/xwiki/sandbox/xwiki-plugin-officeimporter/src/… Maybe can help. If you need a jdom version, I can provide it later if necessary. 3) empty link. like <a/> <a href="">test</a> <a>something</a> http://svn.xwiki.org/svnroot/xwiki/sandbox/xwiki-plugin-officeimporter/src/… this filter can remove empty link tag. Thanks Wang Ning
