java中xml解析器的应用实例

  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());

  }

  }

  public static void main(String[] argv) {

  Dom4jTest dom4j = new Dom4jTest();

  dom4j.generateDocument();

  }

  }
