How to avoid escaping & while escaping " with \"

Question

As a special requirement, I have been trying to escape " with \" while writing XML using DOM.

Unfortunately, when I write text with Document.createTextNode(TextValue), it outputs \". However, the expected is \"

Details:

Writing Text Value:

    public static boolean setDOMElementValue(Document doc, Element elem, String nodeValue) {
    try {
        elem.appendChild(doc.createTextNode(nodeValue));
        return true;
    } catch (DOMException ex) {
        LOG.log(Level.SEVERE, ex.toString());
        return false;
    }
}

Writing XML:

    public static boolean writeDOMToXML(Document doc, String xmlFilePath) {
    try {
        doc.setXmlStandalone(true);
        // write content into xml file

        // Creating TransformerFactory and Transformer
        Transformer tr = TransformerFactory.newInstance().newTransformer();
        // Setting Transformer's output properties
        tr.setOutputProperty(OutputKeys.INDENT, "yes");
        tr.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
        tr.setOutputProperty(OutputKeys.METHOD, "xml");
        tr.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
        tr.setOutputProperty(OutputKeys.STANDALONE, "no");

        // Setting DOMSource and StreamResult
        DOMSource source = new DOMSource(doc);
        File file = new File(xmlFilePath);
        StreamResult result = new StreamResult(new OutputStreamWriter(new FileOutputStream(file)));

        // Transform and Return
        tr.transform(source, result);
        return true;
    } catch (TransformerFactoryConfigurationError | TransformerConfigurationException ex) {
        LOG.log(Level.SEVERE, ex.toString());

        return false;
    } catch (TransformerException | FileNotFoundException ex) {
        LOG.log(Level.SEVERE, ex.toString());
        return false;
    }
}

When you build a text node with the DOM, you should simply put in any string in there literally e.g. doc.createTextNode("\""). When you serialize the DOM tree the serializer will take care of escaping any character as needed (but within a text node there is no need to escape a double or single quote, that is only necessary inside an attribute value, depending on the attribute value delimiter).
