Strings to SAX events
Folks,
We're in the process of writing a Transformer, which, of course, outputs
SAX
events... but, in the midst of this stream , we need to insert an
XML element stored in a string.
To do this we're groping in the dark trying something like this:
JaxpParser respParser = new JaxpParser();
respParser.parse( new InputSource(new StringReader(str)),
new EmbeddedXMLPipe(contentHandler));
Which fails giving this:
org.apache.cocoon.ProcessingException: Failed to execute pipeline.:
java.lang.ClassCastException
...
Caused by: java.lang.ClassCastException

The classes we use are:
org.apache.avalon.excalibur.xml.JaxpParser;
org.xml.sax.InputSource;
java.io.StringReader;
org.apache.cocoon.xml.EmbeddedXMLPipe;
And the environment is:
Solaris 5.8
JDK 1.4.1_01
Tomcat 4.1.12-LE-jdk14
Cocoon 2.0.3
May someone please help us ?

R: R: Strings to SAX events
Posted by Luca Morandini <sp...@ipzs.it>.
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.
Best regards,
Luca Morandini

Re: R: Strings to SAX events
Posted by Marcus Crafter <cr...@fztig938.bank.dresdner.net>.
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: Strings to SAX events
Posted by Ludovic de Beaurepaire <lu...@axonie.com>.
Luca
I have the same type of need to produce SVG for barcodes. I have a String
code as parameter, and an external java module to produce graphic
informations. I will do it with an Action obtaining these informations as
java objects, a generator generating corresponding XML datas
(<svg>...</svg>) . A Stylesheet transform it.
But i'm not expert, surely there are other possibilities.

Ludovic

R: Strings to SAX events
Posted by Luca Morandini <sp...@ipzs.it>.
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
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 ?

Hi Damian,
Perhaps it helps : If you are in XSP, the following tags resolve it without
java code :
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsp:page language="java" xmlns:xsp="http://apache.org/xsp"
xmlns:util="http://apache.org/xsp/util/2.0">
...
<util:include-expr>
<util:expr><xsp:expr>
yourXMLString
</xsp:expr></util:expr>
</util:include-expr>
...
Regards,
Ludovic

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

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.

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.

Luca,
In a generator I use flowing code within the generate()-Method. Maybe this
helps:
parser = (Parser)this.manager.lookup(Parser.ROLE);
parser.setConsumer(super.xmlConsumer);
parser.parse(new InputSource(new StringReader(sb.toString())));

R: Strings to SAX events
Posted by Luca Morandini <sp...@ipzs.it>.
Ludovic,
thanks for your kind answer, but we are not in an XSP page (we're writing a
Transformer instead), hence, your suggestion is not truly useful to us.

Re: Strings to SAX events
Posted by Ludovic de Beaurepaire <lu...@axonie.com>.
Try in a XSP the following, data is your xml string :
<util:include-expr>
<util:expr><xsp:expr>
data
</xsp:expr></util:expr>
</util:include-expr>
