RE: XML 2 XML using XSL,DTD XALAN - JAVA

Hi,
thanks for the tip.
I'm using Jaxp, with Xalan 2.6.0, and the transformation result is stored in a 
DOMResult object(I tryed to obtain de DocType like this: ((Document) 
result.getNode()).getDoctype(), it returns null even with the output property 
of the XSL indicating the correct location of the DTD file, besides it even 
keep the XSL encoding). Do you have any ideia of what is going on?I don't know 
why the result Dom tree doesn't have the DTD and encoding desclared in the XSL 
file...
So, If I use XSL 1.0,Will I have to parse the result DOM tree again?
The code that I use to transform is:
-------begin code
 public Document Transform(Document DOM, String XSlFileName) throws Exception{
  TransformerFactory transformerFactory = null;
  Transformer transformer = null;
  DOMResult result = null;
  StreamSource oLocFonteAqruivoXsl = new StreamSource(new 
FileInputStream(XSlFileName));
  transformerFactory = TransformerFactory.newInstance();
  result = new DOMResult();

  transformer = transformerFactory.newTransformer(new StreamSource(new 
FileInputStream(XSlFileName)));
  transformer.transform(new DOMSource(DOM), result);
  return ((Document) result.getNode());
 }
--------end code
thanks a lot,
Roger.


Hi,
thanks for the tip.
The only way to validade the result DOM tree is to parse it
again? The XSL that I'm using has the output property below:

doctype-system="../DTD/MyDTD.dtd"/>

Even with this, the result DOM tree doesn't have a DocType
with it. Does anyone knows why? I tryed to setup the DocType
by code:
Transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"MyDTD.dtd");

Even with this, the resulting DOM tree doesn't have a DocType wiht it.


You will need give some more information:

What processor are you using?

How are you creating the 'result DOM' - ie a DOMResult?

How are you viewing the result to decide that it doesn't contain the
doctype?

Ultimately the answer is 'yes' that the only XSLT 1.0 way to validate
the result is to parse it again. With 2.0 and a schema aware processor
(Saxon 8.x) you should be able to provide a result schema and Saxon will
flag up (halt or warn... not sure?) at transform time any non-valid
output.
