Hi,
I'm using the below code to create a transformation pipeline using SAX and
filters.
The xsl stylesheet is in file style.xsl and xml data is received in the
xmlStream String.
Some static functions that I use are part of a class called SAXProcessing (that
I also
show below).
I can't see what isn't working in this code. I was first using a
XMLFilterImpl object
to generate some xml ( instead of the XMLReader ) and all was working fine. But
when
I solved to replace it with a XMLReader and parse the xml data from a xml data
stream
the problems started...
now the only output I get are the text nodes in my xml data. It seems that my
xsl is
simply being ignored.
Any suggestions?
Cheers,
Filipe

XMLReader xmlReader = null;
try {
SAXParserFactory spfactory =

spfactory.setValidating(false);
SAXParser saxParser =
spfactory.newSAXParser();
xmlReader = saxParser.getXMLReader();
XMLFilter xmlFilter =
SAXProcessing.newXMLTransformerFilter("style.xsl");
xmlFilter.setParent(xmlReader);
TransformerHandler transHand =
SAXProcessing.newTransformerHandlerSerializer( new
StreamResult(System.out));
xmlFilter.setContentHandler(transHand);
xmlReader.parse( new InputSource( new StringReader(xmlStream)));
} catch (Exception e) {

My SAXProcessing functions:

(SAXTransformerFactory)
TransformerFactory.newInstance();
return saxTFactory.newXMLFilter( new StreamSource(xslFileName));

e.printStackTrace();
System.exit(1);
}
return null;
}
private static TransformerHandler newTransformerHandlerSerializer(StreamResult
result){
try {
SAXTransformerFactory saxTFactory =
(SAXTransformerFactory)
TransformerFactory.newInstance();
TransformerHandler transHand =
saxTFactory.newTransformerHandler();
transHand.setResult( result );
Transformer transformer = transHand.getTransformer();
transformer.setOutputProperty(OutputKeys.METHOD, method);
