How to transform DTD with JAXP

[Juhan Voolaid]

Hi

I use JAXP and dom with my xml file to read data, change it and then write the data back to xml file. Problem is that in my new xml file DTD specification is gone. Shortly, from the second line in my xml file that row is missing:
<!DOCTYPE scores SYSTEM "scores.dtd">

this is how i write data(Document document) to my xml file:

DOMSource source= new DOMSource(document.getDocumentElement());
   StreamResult result=new StreamResult(new File("xml/scores.xml"));
   
   TransformerFactory tFactory=TransformerFactory.newInstance();
   try{
   Transformer transformer=tFactory.newTransformer();
   transformer.transform(source, result);
   }
   catch(TransformerConfigurationException e){
   System.out.println(e);
   }
   catch(TransformerException e){
   System.out.println(e);
   }

I don't know what should i do.

OK, found it. If anyone is interested then this should be added to transformer:
transformer.setOutputProperty(javax.xml.transform.OutputKeys.DOCTYPE_SYSTEM, dtd);
where dtd is string "dtdFile.dtd"
