XSLT with DOMSource

Question

I'm trying to do an XSLT transformation with DOMSource as follows:
javax.xml.transform.Transformer transformer = tFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new FileWriter(new File(FileName)));
transformer.transform(source, result);
transformer = tFactory.newTransformer(new StreamSource(new StringReader(XSLT))); // XSLT is XSLT String.
//transformer.transform(new StreamSource(FileName), new StreamResult(new FileOutputStream("C:\\tmp\\2692xslt.xml"))); // Works fine.
transformer.transform(source, new StreamResult(new FileOutputStream("C:\\tmp\\2692xslt.xml"))); // Doesn't work fine.
The last line doesn't produce intented output. But if we read from file, as in last-but-one line, it works fine. Is there something wrong in directly converting from source?
Thanks,
Viikas

Answer 1

The last line doesn't produce intented output. But if we read from file, as in last-but-one line, it works fine. I sense some deliberation of being cryptic, "intended output".
Is there something wrong in directly converting from source?There should not be.
But the problem can be looked from this angle: namely, the last line is done without the intervention of an intermediate step of passing through an identity transformation and reloading whereas the last-but-one line does.
You can do this so that you can check the output now coincide with the "intended output" or not.
//start from your first two lines
javax.xml.transform.Transformer transformer = tFactory.newTransformer();
DOMSource source=new DOMSource(doc);
DOMResult domresult=new DOMResult();
Document doc2=null;
DOMSource source2=null
transformer.transform(source, domresult);
doc2=(Document)domresult.getNode();
source2=new DOMSource(doc2);
//your line
transformer = tFactory.newTransformer(new StreamSource(new StringReader(XSLT))); // XSLT is XSLT String.
// Does it work fine (according to your sense) now?
//This should produce the same output as your last-but-one line being your "intended output" without passing through saving and reloading physical file and all done in memory.
transformer.transform(source2, new StreamResult(new FileOutputStream("C:\\tmp2692xslt.xml")));Edited by: tsuji on Feb 29, 2012 7:19 AM
