Jdom方式创建/解析xml

?

1.新建文件名为：Jdomdemo.java，代码：

package com.test; import java.io.File;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.util.Iterator;import java.util.List; import org.jdom.Attribute;import org.jdom.Document;import org.jdom.Element;import org.jdom.JDOMException;import org.jdom.input.SAXBuilder;import org.jdom.output.XMLOutputter; import com.inter.XmlDocument; public class JDomDemo implements XmlDocument{     public void createXml(String fileName)    {        Document document;          Element  root;          root=new Element("employees");          document=new Document(root);          Element employee=new Element("employee");          root.addContent(employee);          Element name=new Element("name");          name.setText("ddvip");          employee.addContent(name);          Element sex=new Element("sex");          sex.setText("m");          employee.addContent(sex);          Element age=new Element("age");          age.setText("23");          employee.addContent(age);          XMLOutputter XMLOut = new XMLOutputter();          try {              XMLOut.output(document, new FileOutputStream(fileName));              } catch (FileNotFoundException e) {                 e.printStackTrace();                  } catch (IOException e) {                     e.printStackTrace();                      }      }     public void parserXml(String fileName)    {        SAXBuilder sax = new SAXBuilder();        try {         Document xmlDom = sax.build(new File(fileName));         Element root = xmlDom.getRootElement();         System.out.println(root.getName());         List childList = root.getChildren();         Iterator listIt = childList.iterator();         while(listIt.hasNext()){          Element element = (Element)listIt.next();          System.out.println(element.getName());         }         Element firstChild = (Element) childList.get(0);         List attrList = firstChild.getAttributes();         Iterator attrIt = attrList.iterator();         while(attrIt.hasNext()){          Attribute  attr = (Attribute ) attrIt.next();          System.out.println(attr.getName());          System.out.println(attr.getValue());          System.out.println(attr.getAttributeType());         }         List sonList = firstChild.getChildren();         Iterator sonIt = sonList.iterator();         while(sonIt.hasNext()){          Element temp = (Element)sonIt.next();          System.out.println(temp.getName()+"："+temp.getValue());         }        } catch (JDOMException e) {         e.printStackTrace();        } catch (IOException e) {         e.printStackTrace();        }        System.out.println("----jdom 解析完毕-----");    } }

2.编写测试类，TestJdom.java，代码如下：

public class TestDom{    public static void main(String[] args)    {Jdomdemo    jdom=  new  Jdomdemo();//创建的xml见图一jdom.createXml("D://employee.xml");//解析的xml见图二jdom.parseXml("E://employee.xml");          }}
