R: R: Strings to SAX events
Steven,
first: we'd like to thank you for your help :)
Second: we've tried to use your suggestion... to no avail :(
Here's the failing code:
InputSource source= new InputSource(new StringReader(svgs));
XercesParser respParser;
respParser= new XercesParser();
ChartXMLConsumer cons= new ChartXMLConsumer((AbstractSAXTransformer)(this));
respParser.setConsumer(cons);
respParser.parse(source);
It fails at the last statement with the dreaded null pointer exc..
The parser we're using is an
org.apache.cocoon.components.parser.XercesParser, while the ChartXMLConsumer
is subclass of an org.apache.cocoon.xml.AbstractXMLConsumer, with suitable
methods added.
We think your idea is to trap some SAX events in the AbstractXMLConsumer
subclass, and pass them along to the Transfomer class; while some SAX
events, like StartDocument/EndDocument aren't passed along.
Well, we've done that, but it fails before even passing a single SAX event
to the transformer... any guess ?
Best regards,
P.S.
Here's the AbstractXMLConsumer subclass code:
public class ChartXMLConsumer extends AbstractXMLConsumer {
AbstractSAXTransformer trasf;
ChartXMLConsumer(AbstractSAXTransformer trasfIn) {
this.trasf= trasfIn;
}
public void processingInstruction(String target, String data)
throws SAXException {

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.

it seems the problem has been solved by filtering out some characters (using
the characters() method) from the input file and deleting both XML header
and DOCTYPE from the string containing the SVG.
I know this solution is weirder than the original problem... but that's a
fact :(

R: Strings to SAX events
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: venerdì 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 ?

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 ?

R: R: Strings to SAX events
Marcus, thanks for you help, but our implementation uses a SAX Transformer. We evaluated Wings and decided to go our own way: I hate re-inventing the wheel, but this time I deemed it necessary.

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.
