演示示例
这是输入需要解析xml文件：
<?xml version="1.0"?>
<class>
<student rollno="393">
<firstname>dinkar</firstname>
<lastname>kad</lastname>
<nickname>dinkar</nickname>
<marks>85</marks>
</student>
<student rollno="493">
<firstname>Vaneet</firstname>
<lastname>Gupta</lastname>
<nickname>vinni</nickname>
<marks>95</marks>
</student>
<student rollno="593">
<firstname>jasvir</firstname>
<lastname>singn</lastname>
<nickname>jazz</nickname>
<marks>90</marks>
</student>
</class>

演示示例：
DOM4JQueryDemo.java
package com.yiibai.xml import java.io.File import java.util.List import org.dom4j.Document import org.dom4j.DocumentException import org.dom4j.Element import org.dom4j.Node import org.dom4j.io.SAXReader public class DOM4JQueryDemo { public static void main(String[] args) { try { File inputFile = new File("input.txt") SAXReader reader = new SAXReader() Document document = reader.read( inputFile ) System.out.println("Root element :" + document.getRootElement().getName()) Element classElement = document.getRootElement() List<Node> nodes = document.selectNodes("/class/student[@rollno=&apos493&apos]" ) System.out.println("----------------------------") for (Node node : nodes) { System.out.println("\nCurrent Element :" + node.getName()) System.out.println("Student roll no : " + node.valueOf("@rollno") ) System.out.println("First Name : " + node.selectSingleNode("firstname").getText()) System.out.println("Last Name : " + node.selectSingleNode("lastname").getText()) System.out.println("First Name : " + node.selectSingleNode("nickname").getText()) System.out.println("Marks : " + node.selectSingleNode("marks").getText()) } } catch (DocumentException e) { e.printStackTrace() } } }
这将产生以下结果:
Root element :class ---------------------------- Current Element :student Student roll no : 493 First Name : Vaneet Last Name : Gupta First Name : vinni Marks : 95
