Question

I have a org.w3c.dom.Document.
To generate the xml is no problem.
But how can I generate json out of the document ?

this is the code to get the xml string

        TransformerFactory transfac = TransformerFactory.newInstance();
        Transformer trans = transfac.newTransformer();
        trans.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
        trans.setOutputProperty(OutputKeys.INDENT, "yes");

        // create string from xml tree
        StringWriter sw = new StringWriter();
        StreamResult result = new StreamResult(sw);
        DOMSource source = new DOMSource(document);
        trans.transform(source, result);
        String xmlString = sw.toString();

Just to solve this question.
At the end I used a different approach.
I saved the data in a Tree.

Then for Rendering the JSONView I used the JacksonJsonView Mapper.
And for Rendering the XML I used an XML Marshaller.
