XML 04 dom4j Element和Attribute类

以解析NewFile.xml 中的数据为例

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

public class ParseXML{
      public static void main(String[] args) throws Exceptions{
            SAXReader reader = new SAXReader();
            Document document = reader.read("src/NewFile.xml");

            Element root = document.getRootElement();

            Iterator<Element> it = root.elementIterator();  //在本例中, 获取到了根元素, goodslist 
            while(it.hasNext()){
                    Element ele = it.next();  //在本例中, 获取到了第一个子元素, good
   /* 获取指定标签下的指定标签 */
            if(ele.getName().equals("good"))  //  检查
元素名称是否为good
            {  
              Element name = ele.element("name");  //获取到了good下名字为name(商品名称)的元素
              if(name != null)
                System.out.println(name.getText());  //输出商品名称的内容
            }

                    System.out.println(ele.getName());
                    Iterator<Attribute> attributes = ele.attributeIterator();
                    while(attributes.hasNext()){
                        Attribute ab = attribute.next();
                        System.out.println(ab.getName()+":"+ab.getValue());
                    }
            }
       /*
        Element ele = null;
        ele.elementIterator("good");  //遍历所有名字为good的子元素
       
        Attribute ab = null;
        ab.getName();   //获取属性的名字
        ab.getValue();  //获取属性的值 
       ab.getDocument(); //得到所在的文档对象

       */ } }

/* Output:
  香蕉
  good
  id:1001
  production_date:2018-4-1
苹果
  good
  id:1002
  ...
*/

NewFile.xml

<?xml version="1.0" encoding="UTF-8"?>  
<goodslist>  
    <good id="1001" production_date="2018-4-1"> 
         <price>12</price>  
         <name>香蕉</name>
         <place>广州</place>
    </good>     
    <good id="1002">
         <price>39</price>  
         <name>苹果</name>
         <place>北京</place>
    </good>     
    <good id="1003">

         <name>芒果</name>
