Re: [xwiki-users] Rendering mail content in a wiki page

Hello, I'm back on this subject, so reviving this old thread ... 2012/5/29 Sergiu Dumitriu <sergiu(a)xwiki.com> I am currently trying to follow this path. To take advantage of blockquotes replacement (replacing "> " blocks), and icon transformations, I tried to parse my email plain text content with a xwiki/2.1 parser to generate some XDOM, then feed this to a customized xhtml/1.0 parser. The issue is that in this XDOM, many things already have been interpreted by the parser (for example, "**" into Format.BOLD, etc), and so if I want to "forget" about those formatting instructions, my customized renderer as to put back what should be the original text (with same example, do something like printRaw("**") ). Putting back all this, pretty much looks like rewritting an xwiki/2.1 renderer ... So I changed my mind, and extended the XWikiSyntaxChainingRenderer (to sort of render most things back to what they looked like before parsing), and overrided only the parts I wanted to generate XHTML for (for example, I overloaded the beginQuotation(), endQuotation() and beginQuotationLine() methods). For these overloaded parts, I used an XHTMLWikiPrinter. Going further in my Frankenstein mood, I created my own "ChainingPrintRenderer", joyfully mixing together both worlds (XHTMLRenderer and AbstractXWikiSyntaxRenderer) without no real understanding of what I was doing, and put this in the initialize() : ListenerChain chain = new XWikiSyntaxListenerChain(); setListenerChain(chain); // Construct the listener chain in the right order. Listeners early in the chain are called before listeners // placed later in the chain. chain.addListener(this); chain.addListener(new LookaheadChainingListener(chain, 2)); chain.addListener(new GroupStateChainingListener(chain)); chain.addListener(new BlockStateChainingListener(chain)); chain.addListener(new ConsecutiveNewLineStateChainingListener(chain)); chain.addListener(new EmptyBlockChainingListener(chain)); chain.addListener(new MetaDataStateChainingListener(chain)); chain.addListener(new XWikiSyntaxChainingRenderer(chain, this.linkReferenceSerializer, this.imageReferenceSerializer)); chain.addListener(new XHTMLEmailChainingRenderer(this.linkRenderer, this.imageRenderer, chain)); Obviously, weird manipulations of mad scientist ... As the mad scientist of the story, I created something that lives (and seems to produce something close to what I expected), but with bad number of legs and arms, and now I'm not sure on how to fix it. Currently, though generated XDOM contains what I expect (some QuotationBlock objects), it seems beginQuotation() is never triggered, while endQuotation() correctly occurs when supposed to be... (in fact I checked that beginQuotation() is never called). This is a bit too ugly to ask for help, but in case you have any idea on how to fix this ... I'd prefer to write a real Parser (as initially recommended by Vincent), but was frightened when looking at the samples ;-)
