Hi Vincent, I try to make the xhtmlparser work for the link. I have see the test case links.test in xwiki-core-rendering. I have some questions. 1) the xhtmlparser don't handle the rel attribute. Because wikimodel don't pass the information in xhtmlparser. see http://code.google.com/p/wikimodel/issues/detail?id=47. When this is fixed, I think rel can works. 2) The output of <a href="mailto:[email protected]">mailto:[email protected]</a> should be [[mailto:[email protected]>mailto:[email protected]]] but not [[mailto:[email protected]]]. We should not remove the label information of mailto. Consider if the input is <a href="mailto:[email protected]">Contact me</a>, the output should be [[mailto:[email protected]>Contact me]] -- Thanks Wang Ning
