利用dom4j+xpath对xml文档进行解析示例

package com.yxfyg.test;

import java.io.File;
import java.util.List;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

public class XPathTest {

    public static void main(String[] args) {
        try {
            SAXReader reader = new SAXReader();
            Document document = reader.read(new File("src/xml/stus.xml"));
            Element rootElement = document.getRootElement();
            Element nameElement = (Element)rootElement.selectSingleNode("//name");
            System.out.println(nameElement.getText());
            System.out.println("===================");
            List<Element> elements = rootElement.selectNodes("//name");
            for(Element element:elements) {
                String name = element.getText();
                System.out.println("name:"+name);
            }
        } catch (DocumentException e) {
            e.printStackTrace();
        }
    }
}
