如何将一个Document对象转换为XML文本文件 没分了 恳请帮忙

Question

DOM4j:
OutputFormat format = OutputFormat.createPrettyPrint(); // 格式化输出
format.setEncoding("GBK"); // 指定XML编码
writer = new XMLWriter(new FileWriter(new File(fileName)), format);
writer.write(document); // 将document中的内容写入文件中
另外一个类似,给分吧.

Answer 1

粗心的人
org.jdom.output 下还有两个输出器SAXOutputter
和
DOMOutputter不过这两个输出器都要求参数提供一个输出流,而不是直接输出到字符串

Answer 2

//用DOM规范将生DOM对象树输出到输出流中
    public static void saveToOutputStreamUseDom(Document doc,
                                                String encoding,
                                                OutputStream outputStream) {
        try {
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            DOMImplementation impl = builder.getDOMImplementation();
            DOMImplementationLS implls = (DOMImplementationLS) impl;
            LSSerializer domWriter = implls.createLSSerializer();
            DOMConfiguration domConfig =domWriter.getDomConfig();
            boolean isSupport =domConfig.canSetParameter("format-pretty-print",new Boolean("true"));
            if(isSupport){
                domConfig.setParameter(
                                      "format-pretty-print",
                                       new Boolean("true"));
            }else{
                System.out.println("不支持美化文档！");
            }
            LSOutput output = implls.createLSOutput();
            output.setByteStream(outputStream);
            output.setEncoding("GBK");
            domWriter.write(doc, output);        } catch (Exception e) {
            e.printStackTrace();
        }    }

Answer 3

DOM用XMLSerializer ，DOM4j用XMLWriter
