（四）Jsoup 获取 DOM 元素属性值

第一节： Jsoup 获取 DOM 元素属性值

Jsoup获取DOM元素属性值

比如我们要获取博客的href属性值：

我们这时候就要用到Jsoup来获取属性的值 ：

我们给下示例代码：

 package com.javaxk.jsoup;

 import org.apache.http.HttpEntity;
 import org.apache.http.client.methods.CloseableHttpResponse;
 import org.apache.http.client.methods.HttpGet;
 import org.apache.http.impl.client.CloseableHttpClient;
 import org.apache.http.impl.client.HttpClients;
 import org.apache.http.util.EntityUtils;
 import org.jsoup.Jsoup;
 import org.jsoup.nodes.Document;
 import org.jsoup.nodes.Element;
 import org.jsoup.select.Elements;

 public class Demo4 {

     public static void main(String[] args) throws Exception{
         CloseableHttpClient httpclient = HttpClients.createDefault(); // 创建httpclient实例
         HttpGet httpget = new HttpGet("http://www.cnblogs.com/"); // 创建httpget实例

         CloseableHttpResponse response = httpclient.execute(httpget); // 执行get请求
         HttpEntity entity=response.getEntity(); // 获取返回实体
         String content=EntityUtils.toString(entity, "utf-8");
         response.close(); // 关闭流和释放系统资源

         Document doc=Jsoup.parse(content); // 解析网页 得到文档对象

         Elements linkElements=doc.select("#post_list .post_item .post_item_body h3 a"); //通过选择器查找所有博客链接DOM
         for(Element e:linkElements){
             System.out.println("博客标题："+e.text());
             System.out.println("博客地址："+e.attr("href"));
             System.out.println("target:"+e.attr("target"));
         }

         Element linkElement=doc.select("#friend_link").first();
         System.out.println("纯文本："+linkElement.text());
         System.out.println("html："+linkElement.html());

     }
 }
