Hi Reinhard,

thanks for the last post. I also need to add a string as XML elements
into an XSP generator and I used your suggestion (below). It seems
to work well, but I have two questions:

1) I've noticed that the API states that the Parser is deprecated. I'm
currently using 2.0.3, if I choose to use this method will it effect me
being able to move to a newer version of cocoon at some time in the


future?


2) When I generate my XML elements it seems that the parser is including
the ?xml version=1.0 encoding=UTF-8? header. Is there a way to get
the parser not to include it, as it is causing me problems?

Thanks in advance!
Damian.

Yep, you are right. I developed the component long time ago ... Please try
org.apache.avalon.excalibur.xml.JaxpParser.


 2) When I generate my XML elements it seems that the parser is including

Currently there is a problem with the encoding (always UTF-8 encoding is
used) when you use Xalan. As far as I know those problem don't arise if you
use Saxon.

I don't know how you can remove the processing instruction.

Reinhard

Re: R: Strings to SAX events

2002-11-08 Thread Marcus Crafter 
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 ?

Cheers,

Marcus

RE: R: Strings to SAX events

2002-11-08 Thread Steven Cummings 
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.
