jdom2 Encoding Problem in XML UTF-8 Output

Question

I try to update some attribute values an existing XML file using jdom2. I'm getting the utf8 encoding problem when I create the xml file.

The attribute value is "1 student Noun".

But the value I see in the output is :

1	student	Noun

The code I have written is shown below:

SAXBuilder builder = new SAXBuilder();
            Document document = document = builder.build(filePath);

            Element root = document.getRootElement();

            for(Element sentenceElement : root.getChildren("sentence")){

                String transcriptionText = "";

                 for(Element transcriptionElement : sentenceElement.getChildren("transcription")){

                     for(Element wordElement : transcriptionElement.getChildren("word")){
                            transcriptionText += " "+wordElement.getAttributeValue("text");
                     } 

                     transcriptionParser = ParserUtil.getResponse(transcriptionText);
                     transcriptionElement.getAttribute("text").setValue(transcriptionText);
                     transcriptionElement.getAttribute("parser").setValue(transcriptionParser);
                 }

                 for(Element translationElement : sentenceElement.getChildren("translation")){

                        translationParser = getResponse(translationElement.getAttributeValue("text"));
                        translationElement.getAttribute("parser").setValue(translationParser);

                 }
            }

            Format format = Format.getPrettyFormat();

            XMLOutputter xmlOutput = new XMLOutputter(format);


            /*try (OutputStream out = new FileOutputStream(filePath)) {
               xmlOutput.output(document, out);
              }catch(Exception e){
                 e.printStackTrace();
              }
            }*/

            xmlOutput.output(document, Files.newBufferedWriter(Paths.get(filePath),StandardCharsets.UTF_8));

I have used both of the options:

xmlOutput.output(document, Files.newBufferedWriter(Paths.get(filePath),StandardCharsets.UTF_8));

and

    try (OutputStream out = new FileOutputStream(filePath)) {
         xmlOutput.output(document, out);
   }catch(Exception e){
         e.printStackTrace();
   }

But none of them have been solved the problem. How to solve the problem?

Answer 1

The string "1 student Noun" obviously contains tab characters between the words.

So if the XML output contains 1	student	Noun thats' perfectly ok. The tab characters has the Unicode value 9 and 	 is a proper XML entity to represent that.
