Re: R: Strings to SAX events
Hi Luca, Have you seen the WingsTransformer in 2.1 scratchpad ? It converts xcml (over at Krysalis) chart markup to svg which you can then give to svg2png/etc. I'm using it at the moment and it works quite well for pie, line and bar charts. Perhaps that might be of use, as it works nicely with Cocoon ?

RE: R: Strings to SAX events
Luca, I'm doing something very similar to implement a SOAPTransformer. What I've done is implement an XMLConsumer so that it passes ALL events that it recieves directly to the transformer's super-class (super.startElement, super.endElement... etc.) Because you've probably already started an output SAX stream that you want to embed the content of the string in, you simply neglect to pass along the startDocument and endDocument events. This is very important. Otherwise, the solution is pretty simple. Hope this helps. /S Luca Morandini [EMAIL PROTECTED] wrote: Ludovic, we're writing a Transformer to produce SVG (and JPEG/PNG optionally) charts.
