//EDIT Sorry i'm very new stackoverflow.. yes this is from a program that i've written.

That's part of code from the program

try {
        DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder docBuilder = docFactory.newDocumentBuilder();

        // XML Kok Ismi
        Document doc = docBuilder.newDocument();
        Element rootElement = doc.createElement("ARTICLES");
        doc.appendChild(rootElement);

        for (Nesne nesne : userList) {
            // ARTICLE ELEMENT
            Element ARTICLE_ID= doc.createElement("ARTICLE ");
            rootElement.appendChild(ARTICLE_ID);

            //ID
            Attr attr = doc.createAttribute("ID");
            attr.setValue(String.valueOf(nesne.getArticleID()));
            MAKALE_ID.setAttributeNode(attr);

            //ARTICLE_CATEGORY_ID
            Element ARTICLE_CATEGORY_ID= doc.createElement("ARTICLE_CATEGORY_ID");
                 ARTICLE_CATEGORY_ID.appendChild(doc.createTextNode(String.valueOf(nesne.getARTICLE_CATEGORY_ID())));
            ARTICLE_ID.appendChild(ARTICLE_CATEGORY_ID);
            //[ARTICLE_NAME]
            Element ARTICLE_NAME= doc.createElement("ARTICLE_NAME");
            ARTICLE_NAME.appendChild(doc.createTextNode(nesne.getARTICLE_NAME()));
            ARTICLE_ID.appendChild(ARTICLE_NAME);

            //[ARTICLE_EXTENSION]
            Element ARTICLE_EXTENSION= doc.createElement("ARTICLE_EXTENSION");
            ARTICLE_EXTENSION.appendChild(doc.createTextNode(nesne.getARTICLE_EXTENSION()));
            ARTICLE_ID.appendChild(ARTICLE_EXTENSION);

            //[ARTICLE_BYTE]
            Element ARTICLE_BYTE= doc.createElement("ARTICLE_BYTE");
            ARTICLE_BYTE.appendChild(doc.createTextNode(nesne.getARTICLE_BYTE().toString()));
            ARTICLE_ID.appendChild(ARTICLE_BYTE);

            //[ARTICLE_DATE]
            Element ARTICLE_DATE = doc.createElement("ARTICLE_DATE");
            ARTICLE_DATE.appendChild(doc.createTextNode(nesne.getARTICLE_DATE()));
            ARTICLE_ID.appendChild(ARTICLE_DATE);

            //[ARTICLE_ACTIVE]
            Element ARTICLE_ACTIVE= doc.createElement("ARTICLE_ACTIVE");
          ARTICLE_ACTIVE.appendChild(doc.createTextNode(String.valueOf(nesne.getArticleActive())));
            ARTICLE_ID.appendChild(ARTICLE_ACTIVE);

        }
        // write the content into xml file
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        DOMSource source = new DOMSource(doc);
        StreamResult result = new StreamResult(new File("dosyalar.xml"));

        // Output to console for testing
        // StreamResult result = new StreamResult(System.out);
        transformer.transform(source, result);

        System.out.println("File saved!");

Your problem appears to be here:

nesne.getARTICLE_BYTE().toString()

I'm not familiar with your Nesne class, but I can tell that the method, getARTICLE_BYTE() returns a byte array, that calling toString() on it will return the useless information that you're currently seeing, and that if this needs to be stored, then you somehow need to store the entire array. Using a for loop and storing the array as the String representations of each byte would not be the most efficient thing to do and would lead to a super-large unreadable XML, so perhaps you could store it off of the XML and pass a reference to the byte array file in the XML. Or store in a database as a BLOB. Note that this is not something I do much of, and so I'm no expert.
