Ludovic, we're writing a Transformer to produce SVG (and JPEG/PNG optionally) charts. The idea is having the chart description and associated data in XML as input, transform them, ending up with a nice SVG to be serialized.
We're using a charting library which doesn't produce a SAX stream, but outputs the SVG element as a string, hence, the need to insert this XML elements in the output SAX stream. I hope this clears the matter :) Luca Morandini Istituto Poligrafico e Zecca dello Stato [EMAIL PROTECTED] [EMAIL PROTECTED] > -----Messaggio originale----- > Da: Ludovic de Beaurepaire [mailto:ludovic.debeaurepaire@;axonie.com] > Inviato: venerd́ 8 novembre 2002 11.26 > A: [EMAIL PROTECTED] > Oggetto: Re: Strings to SAX events > > > Luca > > Sorry if it is NOK, but i didn't understand why you want to add > XML datas in > the transformer instead of in your pipeline's generator ?
