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
