dom4j如何处理转义字符

public static void execute(/*一些参数*/) throws Exception {     filepath = "D:\\form.xml";     SAXReader reader = new SAXReader();     Document doc = reader.read(new File(filepath));               //......一些处理               XMLWriter xmlWriter = new XMLWriter(new FileOutputStream(filepath));     xmlWriter.write(doc);     xmlWriter.close(); }

得到的xml文件里面的"变成了双引号，>没变。
我想让他都不变，"还是"，不要变成双引号

saxRead.setEncoding("UTF-8");指定你使用的格式，GB2312

OutputFormat format = OutputFormat.createPrettyPrint();             format.setEncoding("utf-8");             XMLWriter writer = new XMLWriter(new OutputStreamWriter(new FileOutputStream(filename), "utf-8"), format);             writer.write(document);             writer.close();
