XML 解析 JDOM --- --- 推荐

 

创建一个XML:

 

 package com.jdom;import java.io.FileWriter;import org.jdom.Comment;import org.jdom.Document;import org.jdom.Element;import org.jdom.output.Format;import org.jdom.output.XMLOutputter;public class JdomCreateXml {public static void main(String[] args)throws Exception {Element root = new Element("person");root.setAttribute("id", "01");Comment comment = new Comment("this is test JDOM producing xml file");root.addContent(comment);Element student1 = new Element("student").setAttribute("sId", "0101");Element name1 = new Element("name");name1.addContent("zhangsan");Element age1 = new Element("age");age1.addContent("20");Element sex1 = new Element("sex");sex1.addContent("male");student1.addContent(name1);student1.addContent(age1);student1.addContent(sex1);Element student2 = new Element("student").setAttribute("sId", "0102");Element name2 = new Element("name");name2.addContent("lisi");Element age2 = new Element("age");age2.addContent("21");Element sex2 = new Element("sex");sex2.addContent("male");student2.addContent(name2);student2.addContent(age2);student2.addContent(sex2);Element student3 = new Element("student").setAttribute("sId", "0103");Element name3 = new Element("name");name3.addContent("wangwu");Element age3 = new Element("age");age3.addContent("22");Element sex3 = new Element("sex");sex3.addContent("female");student3.addContent(name3);student3.addContent(age3);student3.addContent(sex3);root.addContent(student1);root.addContent(student2);root.addContent(student3);Document document = new Document(root);Format format = Format.getPrettyFormat();format.getExpandEmptyElements();format.setEncoding("UTF-8");XMLOutputter out = new XMLOutputter(format);out.output(document, new FileWriter("src/com/jdom/person.xml"));}}

 

 

解析XML:

 

package com.jdom;import java.io.File;import java.util.List;import org.jdom.Document;import org.jdom.Element;import org.jdom.input.SAXBuilder;public class JdomReadXml {/** * @param args */public static void main(String[] args)throws Exception {SAXBuilder sax = new SAXBuilder();Document document = sax.build(new File("src/com/jdom/person.xml"));Element root = document.getRootElement();System.out.println("<"+root.getName()+ " id="+ root.getAttributeValue("id") + " >");List<Element> listStudent = root.getChildren();for(Element student: listStudent){System.out.println(" <"+student.getName()+">");List<Element> listChid = student.getChildren();for(Element chid: listChid){System.out.print(" <"+chid.getName()+">");System.out.print(chid.getValue());System.out.println("</"+chid.getName()+">");}System.out.println(" </"+student.getName()+">");}System.out.println("</"+root.getName()+">");}}

 

 

XML:

 <?xml version="1.0" encoding="UTF-8"?><person id="01"> <!--this is test JDOM producing xml file--> <student sId="0101"> <name>zhangsan</name> <age>20</age> <sex>male</sex> </student> <student sId="0102"> <name>lisi</name> <age>21</age> <sex>male</sex> </student> <student sId="0103"> <name>wangwu</name> <age>22</age> <sex>female</sex> </student></person>
