Java USES Jdom to read the XML parsing instance

This article illustrates an example of how Java USES Jdom to read XML parsing. Share with you for your reference, as follows:

package com.yanek.demo.xml.test;
import java.io.File;
import java.io.IOException;
import java.util.Iterator;
import java.util.List;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.JDOMException;
import org.jdom.input.SAXBuilder;
public class JdomReadXml {
 
 public static void main(String[] args) {
 /**
  * <?xml version="1.0" encoding="UTF-8"?> <actions m="001"><action
  * path="/test" class="com.mystruts.demo.LoginAction"><forward
  * name="success" url="test.jsp" /><forward name="failure"
  * url="failure.jsp" /></action><action path="/user"
  * class="com.mystruts.demo.UserAction"><forward name="success"
  * url="test.jsp" /><forward name="failure" url="failure.jsp" /></action></actions>
  */
 SAXBuilder sax = new SAXBuilder();
 Document doc;
 try {
  try {
  doc = sax.build(new File("mystruts.xml"));
  Element root = doc.getRootElement();
  List actions = root.getChildren();
  //Traverses to get the first-level child nodes under the root node and passes the recursive method as an input parameter
  for (Iterator i = actions.iterator(); i.hasNext();) {
   Element action = (Element) i.next();
   System.out.println(action.getAttributeValue("path"));
   System.out.println(action.getAttributeValue("class"));
   List forwards = action.getChildren();
   for (Iterator j = forwards.iterator(); j.hasNext();) {
   Element forward = (Element) j.next();
   System.out.println(forward.getAttributeValue("name"));
   System.out.println(forward.getAttributeValue("url"));
   }
  }
  } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
  }
 } catch (JDOMException e) {
  e.printStackTrace();
 }
 }
}

Output:

/test
com.mystruts.demo.LoginAction
success
test.jsp
failure
failure.jsp
/user
com.mystruts.demo.UserAction
success
test.jsp
failure
failure.jsp
