XML解析----- SAXReader

1.直接使用SAXReader 

package com.crown.saxdecoder;

import java.io.InputStream;
import java.util.Iterator;
import java.util.List;

import org.apache.commons.lang3.StringUtils;
import org.dom4j.Attribute;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

public class SaxReaderTest{
	
	
	public static void main(String[] args) {
		new SaxReaderTest().doParse();
	}
	
	
	public void doParse() {
		SAXReader reader= new SAXReader();
		Document document =null;
		try {
			document= reader.read(getInputStream());			
		} catch (DocumentException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		Element rootElement = document.getRootElement();
		getNodes(rootElement);
	}
	
	
	public  InputStream getInputStream(){
		return this.getClass().getClassLoader().getResourceAsStream("student.xml");
	}
	
	public void getNodes(Element rootElement) {
		System.out.println("节点名称："+ rootElement.getName());
		//获得当前节点的所有属性
		List<Attribute> attributes = rootElement.attributes();
		attributes.forEach(attribute -> {
			System.out.println("属性名称："+attribute.getName()+","+"属性值:"+attribute.getText());
		});
		
		if (!StringUtils.isEmpty(rootElement.getTextTrim())) {
			System.out.println("节点名称："+ rootElement.getName()+"<"+"节点值："+rootElement.getText()+">");
		}else {
//			System.out.println(rootElement.getText());
		}
		//获得所有节点
		Iterator<Element> elementIterator = rootElement.elementIterator();
		while(elementIterator.hasNext()) {
			getNodes(elementIterator.next());
		}
		
	}
}
