Help with SAXSource and javax.xml.transform.Transformer

[Andreas]

Hi!

I fail to catch events when transforming xml.
I have some code that successfully transforms an xml

... code ...
// Setup XSL transformer
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(xslStreamSource);

// Setup XML result
ByteArrayOutputStream baos = new ByteArrayOutputStream();
BufferedOutputStream bos = new BufferedOutputStream(baos);
StreamResult transformResult = new StreamResult(bos);

// Do the transform
StreamSource ss = new StreamSource(source);
transformer.transform(ss, transformResult);
... end code ...

Now I need this code to perform some "side effects" when parsing the
original xml. I know it is possible to catch events in a ContentHandler
when parsing xml with XMLReader. I tried this with the following code.

... code ...
// Perform Sideeffects
InputSource is = new InputSource(source);
MyContentHandler mch = new MyContentHandler();
XMLReader reader = XMLReaderFactory.createXMLReader();
reader.setContentHandler(sch);
reader.parse(is);
... end code ...

Ok, so know I know that XMLReader.parse will fire events. Why can't I
use this reader with a SAXSource to catch these events when doing the
transform?

Something like:

... code ...
SAXSource ss = new SAXSource(reader, is);
transformer.transform(ss, transformResult);
... end code ...

Unfortunately this code doesn't produce any events

Any solution for this problem?

Perhaps if you posted a short, self-contained code example (SSCCE) it
would be easier to help you.
