java - 如何在“with\”转义时避免转义 &

Question

作为特殊要求，我一直在尝试越狱"与 \"写作时XML使用 DOM .

不幸的是，当我用 Document.createTextNode(TextValue) 写文本时, 它输出 \" .但是，预期的是 \"

详细信息:

写入文本值:

    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;
    }
}

编写 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;
    }
}

当您使用 DOM 构建文本节点时，您应该简单地在其中输入任何字符串，例如doc.createTextNode("\"")。当您序列化 DOM 树时，序列化程序将根据需要转义任何字符(但在文本节点中不需要转义 double 或单精度字符)引号，仅在属性值内部是必需的，具体取决于属性值定界符)。
