如何用java生成一个xml文件

一个XML文档，可以先构造一个DOM，然后将DOM转化为xml序列，输出或者生成文件。package test;

import java.io.ByteArrayOutputStream;

import java.io.File;

import java.io.FileOutputStream;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.transform.Transformer;

import javax.xml.transform.TransformerFactory;

import javax.xml.transform.dom.DOMSource;

import javax.xml.transform.stream.StreamResult;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

public class Test {

public static void generate(){

try {

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

DocumentBuilder builder = factory.newDocumentBuilder();

Document document = builder.newDocument();

document.setXmlVersion("1.0");

document.setXmlStandalone(true);

Element root = document.createElement_x("MobileNet"); //创建根节点

document.appendChild(root); //将根节点添加到Document对象中

Element pageElement = document.createElement_x("page"); //设置第一个page元素到

pageElement.setAttribute("name", "list.jsp"); //设置page节点的name属性

Element methodElement = document.createElement_x("method"); //设置method节点

methodElement.setTextContent("get"); //给method设置值

pageElement.appendChild(methodElement); //添加method节点到page节点内

Element displayElement = document.createElement_x("display"); //设置method节点

displayElement.setTextContent("list撒旦发放"); //给display设置值

pageElement.appendChild(displayElement); //添加display节点到page节点内

Element request_paramElement = document.createElement_x("request_param");

request_paramElement.setTextContent("request_param1|request_param2");

pageElement.appendChild(request_paramElement);

root.appendChild(pageElement);

pageElement = document.createElement_x("page"); //设置第二个page元素到

pageElement.setAttribute("name", "content.jsp"); //设置page节点的name属性

methodElement = document.createElement_x("method");

methodElement.setTextContent("post");

pageElement.appendChild(methodElement);

displayElement = document.createElement_x("display");

displayElement.setTextContent("content");

pageElement.appendChild(displayElement);

Element url_titleElement = document.createElement_x("url_title"); //设置url_title节点

url_titleElement.setTextContent("title,publisher,published_calendar"); //给url_title设置值

pageElement.appendChild(url_titleElement); //添加url_title节点到page节点内

root.appendChild(pageElement); //将page段加人根节点内

TransformerFactory transFactory = TransformerFactory.newInstance(); //开始把Document映射到文件

Transformer transFormer = transFactory.newTransformer();

DOMSource domSource = new DOMSource(document); //设置输出结果

File file = new File("MobileNetRule.xml"); //生成xml文件

if (!file.exists()) {

file.createNewFile();

}

FileOutputStream out = new FileOutputStream(file); //文件输出流

StreamResult xmlResult = new StreamResult(out); //设置输入源

transFormer.transform(domSource, xmlResult); //输出xml文件

System.out.println(file.getAbsolutePath()); //测试文件输出的路径

TransformerFactory tf = TransformerFactory.newInstance();

Transformer t = tf.newTransformer();

t.setOutputProperty("{/encoding/}","GB2312/");

ByteArrayOutputStream boc = new ByteArrayOutputStream();

t.transform(new DOMSource(document), new StreamResult(boc));

String xmlstring = boc.toString();

System.out.println(xmlstring);

} catch (Exception e) {

e.printStackTrace();

}

}

public static void main(String[] args){

Test.generate();

}

}

JAVA如何写XML文件？

import java.io.*;\x0d\x0a \x0d\x0aimport org.dom4j.*;\x0d\x0a import org.dom4j.io.OutputFormat;\x0d\x0a import org.dom4j.io.XMLWriter;\x0d\x0a \x0d\x0apublic class DOM4JTest {\x0d\x0a public static void main(String[] args) {\x0d\x0a Document doc = DocumentHelper.createDocument();\x0d\x0a doc.addProcessingInstruction("xml-stylesheet", "type='text/xsl href='students.xsl'");\x0d\x0a Element root = doc.addElement("students");\x0d\x0a \x0d\x0a Element eltStu1 = root.addElement("student").addAttribute("sn", "01");\x0d\x0a Element eltName1 = eltStu1.addElement("name");\x0d\x0a Element eltAge1 = eltStu1.addElement("age");\x0d\x0a eltName1.setText("张三");\x0d\x0a eltAge1.setText("20");\x0d\x0a \x0d\x0a Element eltStu2 = root.addElement("student").addAttribute("sn", "02");\x0d\x0a Element eltName2 = eltStu2.addElement("name");\x0d\x0a Element eltAge2 = eltStu2.addElement("age");\x0d\x0a eltName2.setText("李四");\x0d\x0a eltAge2.setText("18");\x0d\x0a \x0d\x0a try {\x0d\x0a OutputFormat format = new OutputFormat("\x0d\x0a ", true);\x0d\x0a format.setEncoding("gb2312");\x0d\x0a // 可以把System.out改为你要的流。\x0d\x0a XMLWriter xmlWriter = new XMLWriter(new PrintWriter(System.out), format);\x0d\x0a xmlWriter.write(doc);\x0d\x0a xmlWriter.close();\x0d\x0a } catch (IOException e) {\x0d\x0a e.printStackTrace();\x0d\x0a }\x0d\x0a }\x0d\x0a }

如何用java代码创建xml文件

用java自带的就可以，有问题可以问我

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;

//构造

public XMLUtil(String name) throws ParserConfigurationException {

filename = name;

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

builder = factory.newDocumentBuilder();

document = builder.newDocument();

}

/**

* 保存到文件

*/

public void toSave() {

try {

TransformerFactory tf = TransformerFactory.newInstance();

Transformer transformer = tf.newTransformer();

DOMSource source = new DOMSource(document);

transformer.setOutputProperty(OutputKeys.ENCODING, "GB2312");

transformer.setOutputProperty(OutputKeys.INDENT, "yes");

PrintWriter pw = new PrintWriter(new FileOutputStream(filename));

StreamResult result = new StreamResult(pw);

transformer.transform(source, result);

} catch (TransformerException mye) {

mye.printStackTrace();

} catch (IOException exp) {

exp.printStackTrace();

}

}

如何用java生成一个XML文件，并且将该文件压

package com.test.io;

import java.io.File;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.OutputStream;

public class CreateXmlFile {

private static final String XML_TITLE = "?xml version=\"1.0\" encoding=\"utf-8\"?";

private static final String FILE_PATH = "d:";

private static final String FILE_SPE = "/";

private static final String CHANGE_LINES = "\n";

private static final String FILE_NAME = "text.xml";

public static void main(String[] args) {

String xml = appendStr();

try {

File file = createXmlFile(FILE_PATH + FILE_SPE + FILE_NAME);

writeDoc(file, xml);

System.out.println("文件已经创建:");

System.out.println("目录:" + FILE_PATH + FILE_SPE + FILE_NAME);

System.out.println("文件内容为:");

System.out.println(xml);

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

/**

* 组装XML内容

* @return

*/

private static String appendStr(){

StringBuffer sb = new StringBuffer();

sb.append(XML_TITLE).append(CHANGE_LINES);

sb.append("book").append(CHANGE_LINES);

sb.append("name").append(CHANGE_LINES);

sb.append("《好玩》").append(CHANGE_LINES);

sb.append("/name").append(CHANGE_LINES);

sb.append("/book").append(CHANGE_LINES);

return sb.toString();

}

/**

* 将内容写入文件

* @param file

* @param str

*/

private static void writeDoc(File file,String str){

OutputStream out = null;

try {

out = new FileOutputStream(file);

out.write(str.getBytes());

}catch(Exception ex){

//

ex.printStackTrace();

}finally{

if(out != null){

try {

out.close();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

}

/**

* 创建文件

* @param path

* @return

* @throws IOException

*/

private static File createXmlFile(String path) throws IOException{

File file = new File(path);

if(!file.exists()){

file.createNewFile();

}

return file;

}

}
