Question

我在转换文档后得到了这个返回XML。以下是XML返回示例：

</ERROR>

这就是我进行转换的方式：

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder parser = factory.newDocumentBuilder();
Document document = parser.newDocument();

Element errorNode = document.createElement("ERROR");
Element detailNode = document.createElement("DETAILS");
CDATASection cd = document.createCDATASection(stackTraceDetails);
detailNode.appendChild(cd);
errorNode.appendChild(detailNode);              
document.appendChild(errorNode);

TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();

Writer stringWriter = new StringWriter();          
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
transformer.setOutputProperty(OutputKeys.CDATA_SECTION_ELEMENTS, "DETAILS");
transformer.transform(new DOMSource(document.getDocumentElement()), new StreamResult(stringWriter));

return stringWriter.toString();

我无法弄清楚这是怎么回事。任何机构都知道这是怎么回事？

异常堆栈跟踪包含行结尾\r\n（Windows）。然而，\n是本地行结束（Linux？），而\r表示为数字XML实体。这只能在<![CDATA[...]]>部分之外表示。

CDATASection cd = document.createCDATASection(stackTraceDetails.replace("\r", ""));

变化可以想象。
