java Element.setTextContent删除换行符

Question

我在创建xml文件时遇到问题。我需要在从数据库中检索并存储到节点中的sting中保留换行符。我无法让它发挥作用。我尝试了以下变化。

Element ele = doc.createElement("productDescription");
ele.setTextContent(text); // this drops the newlines.
ele.appendChild(doc.createTextNode(text)); // this drops the newlines.
ele.setTextContent(text.replace("\n", "
")); // this changes all the newlines to the text "
"

我正在输出文件。

String QueryResults(String query) {
  Document doc = CreateDoc(query);
  StringWriter sw = new StringWriter();
  StreamResult result = new StreamResult(sw);
  DOMSource source = new DOMSource(doc);
  try {
    docTransformer.transform(source, result);
  } catch (TransformerException ex) {
    System.out.println("Failed to convert doc to string: " + ex.getMessage());
    return null;
  }
  return sw.toString();
}

输出的样本将是。

<result>
  <Orders>
    <productName>Widget thingy</productName>
    <productDescription>A really cool widget thingy.\nReally, its cool.</productDescription>
  </Orders>
</result>

这样怎么样：

ele.setTextContent(text.replace("\n", System.getProperty("line.separator")));
