[xwiki-devs] [Rendering] XHTML placeholder for links

Hi, Since recognizing links to be xwiki links is hard (not even always possible) we need to add some extra information when we render wiki syntax content into XHTML (for the WYSIWYG editor for ex) so that we can convert it back to wiki syntax. We have 2 solutions I can think of: 1) Using a span with a class value: <span class="wikilinkplaceholder wikilink"><! [CDATA[Space.ExistingPage]]><a href="/xwiki/bin/view/Space/ ExistingPage">Space.ExistingPage</a></span> 2) Using a comment: <!-- startwikilink:Space.Existing --><span class="wikilink"><a href="/ xwiki/bin/view/Space/ExistingPage">Space.ExistingPage</a></span><!-- stopwikilink --> Pros and cons: * 2) allows not generating visible content in XHTML so that if someone copy/paste our generated XHTML he won't have to add some CSS rule to prevent it from being visible. BTW I'm not even sure we can find a CSS rule to do that in solution 1) so we might need to have 2 spans as in: <span class="startwikilink"><![CDATA[Space.ExistingPage]]></span><span class="wikilinkplaceholder wikilink"><a href="/xwiki/bin/view/Space/ ExistingPage">Space.ExistingPage</a></span><span class="stopwikilink"/> * 1) is harder to code since it requires using a SAX2 LexicalHandler, which btw is not supported by all XML parsers: "This is an optional extension handler for SAX2 to provide lexical information about an XML document, such as comments and CDATA section boundaries. XML readers are not required to recognize this handler, and it is not part of core-only SAX2 distributions." It also requires that I make some modifications to wikimodel since wikimodel currently ignores comments. Solution 2) seems slightly better to me but as it's quite more complex to implement I'd like to be sure that it's the best solution. WDYT? Thanks -Vincent
