JAVA 使用Xpath便捷读取XML元素内容

XML内容：

`<?xml version="1.0" encoding="UTF-8"?>
<!-- 这里是注释，可以写上说明。。。。。。。。。 -->
<!-- 非法字符：< &lt;=<,& &amp;=& -->

JAVA读取代码：

package com.itxml.test;

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 xmlOpenTest1 {
	public static void main(String[] args){	
		try {
			//1. Create SAXReader Object;
			SAXReader srd = new SAXReader();
			//2. Refer xml file path to Document;
			Document content = srd.read(new File("src/xmlDemo/Demo.xml"));
			//3. Get rootelement;
			Element rootElement = content.getRootElement();
			//4. Add jaxen-1.1-beta-6.jar to build path, use Xpath to simplify process;
			//Node nametag = rootElement.selectSingleNode("//name");
			//String name = nametag.getText();
			//System.out.println(name);
			List<Node> nameList = rootElement.selectNodes("//name");
			for(Node node: nameList){
				String nametxt = node.getText();
				System.out.println(nametxt);				
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
		
	}
