xml解析中,通常大家读文件,解析的时候没有问题,但是在写文件的时候常常会碰到乱码等问题,就我的个人体会是一般只要在写文件的时候采用文件流的形式,设置好当前的编码方式,通常就会避免此类问题的发生!下面有两个简单的分别是采用jdom和dom4j实现的例子:
1、dom4j
package org.lyj.xml;
import java.io.OutputStream;
import java.io.UnsupportedEncodingException;
import org.dom4j.Document;
import org.dom4j.Element;
import java.io.FileWriter;
import org.dom4j.io.OutputFormat;
import org.dom4j.Namespace;
import org.dom4j.io.XMLWriter;
import java.io.File;
import java.io.IOException;
import org.dom4j.DocumentHelper;

public class Dom4jTest {
public void generateDocument() {
org.dom4j.DocumentFactory df = new org.dom4j.DocumentFactory();
Document document = df.createDocument();//.createDocument();
Element catalogElement = document.addElement("catalog");
catalogElement.addComment("An XML Catalog");
catalogElement.addProcessingInstruction("target", "text");
Element journalElement = catalogElement.addElement("journal");
journalElement.addAttribute("title", "XML Zone");
journalElement.addAttribute("publisher", "IBM developerWorks");
Element articleElement = journalElement.addElement("article");
articleElement.addAttribute("level", "Intermediate");
articleElement.addAttribute("date", "December-2001");
Element titleElement = articleElement.addElement("title");
titleElement.setText("Java configuration with XML Schema");
Element authorElement = articleElement.addElement("author");
Element firstNameElement = authorElement.addElement("录音机");
firstNameElement.setText("Marcello");
Element lastNameElement = authorElement.addElement("刘");
lastNameElement.setText("Vitaletti");
document.addDocType("catalog",
null, "file://c:/Dtds/catalog.dtd");
document.setXMLEncoding("gb2312");
try {
OutputFormat of = OutputFormat.createCompactFormat();
of.setEncoding("gb2312");
XMLWriter output = new XMLWriter(
new java.io.FileOutputStream(new File("c:/catalog/catalog.xml")),of);
output.write(document);
output.close();
} catch (IOException e) {
System.out.println(e.getMessage());
