初识Jsoup之解析HTML

按照国际惯例,我首先应该介绍下Jsoup是个什么东西,然后在介绍下具体用法,然后在来个demo演示,其实我也是这么想的,小编今天花了一天的时间从学习—>解析页面,总算是成果圆满了吧,啊哈,但是,一个不会总结的程序猿不是一个帅气的程序猿,啊哈,这就意味着我是个帅气的猿猿


什么是Jsoup?

官网网站:http://jsoup.org/ 通俗的将Jsoup就是一个解析网页的东西,然后我们在看下官方的解释:

jsoup

Jsoup的基本用法

demo演示

写在前面:忽略链接内容,小编就是找到一个不错的网站~,啊哈,别想歪了

我们来看下这段的源代码:

由此我们知道了大体的样子,现在我们来写编码

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

import java.io.IOException;

/**
 * 使用Jsoup解析url
 * @tag:url :http://sex.guokr.com/
 * Created by monster on 2015/12/11.
 */
public class JsoupZX {
    public static void main(String[] args){
        final String url="http://sex.guokr.com/" ;

        try {

            Document doc = Jsoup.connect(url).get();

           Elements container = doc.getElementsByClass("container");

            Document containerDoc = Jsoup.parse(container.toString());

            Elements module = containerDoc.getElementsByClass("module-list");

            Document moduleDoc = Jsoup.parse(module.toString());

            //Elements clearfix = moduleDoc.getElementsByClass("clearfix");  //DOM的形式

            Elements clearfix = moduleDoc.select(".clearfix");  //选择器的形式

            for (Element clearfixli : clearfix){
                Document clearfixliDoc = Jsoup.parse(clearfixli.toString());
                Elements kind = clearfixliDoc.select(".board-tag");  //选择器的形式
                Elements title = clearfixliDoc.select(".tit-post");
                Elements author = clearfixliDoc.select("span a");


               System.out.println("类别"+kind.text());  //分类
               System.out.println("标题"+title.text());  //标题
               System.out.println("作者"+author.text());  //作者
                System.out.println("详情链接"+title.attr("href"));  //标题下的链接

                System.out.println("=====================");

            }
              //  String title = clearfixli.getElementsByTag("a").text();


          //  System.out.println(clearfix);

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

输出结果:

内容如下:

然后我们看下源码:

编码:

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

import java.io.IOException;

/**
 * 使用Jsoup解析帖子详情和评论
 * @tag: url:http://sex.guokr.com/post/1100992/
 * Created by monster on 2015/12/11.
 */
public class JSoupDetail {

    public static void main(String args[]){
        final String url=  "http://sex.guokr.com/post/1100992/";


        try {

            Document doc = Jsoup.connect(url).get();

            Elements container = doc.getElementsByClass("container");

            Document containerDoc = Jsoup.parse(container.toString());

            String articleTitle =  containerDoc.getElementById("articleTitle").text();
            String authorName = containerDoc.getElementById("authorName").text();
            String time = containerDoc.select("span").first().text();
            String imgphotoUrl=containerDoc.select("img").get(1).attr("src");
            System.out.println("标题:" + articleTitle); //标题
            System.out.println("作者:"+authorName); //作者
            System.out.println("发布时间:"+time); //发布时间
            System.out.println("作者头像的url:"+imgphotoUrl); //发布时间


            Element articleContent =  containerDoc.getElementById("articleContent");
            Document articleContentDoc = Jsoup.parse(articleContent.toString());


           int size=  articleContentDoc.select("p").size();
            System.out.println("段落数:"+size);

            System.out.println("帖子内容:");

            for (int i=0;i<size;i++){
               String content =  articleContentDoc.select("p").get(i).text();
                System.out.println(content);
            }

            System.out.println("================================================");
        System.out.println("帖子评论区域(按照楼层分布)");

            Elements cmts =containerDoc.getElementsByClass("cmts");
            Document cmtsDoc = Jsoup.parse(cmts.toString());
            System.out.println("评论楼层:"+cmtsDoc.select("span").first().text());

            Elements cmtslist =cmtsDoc.getElementsByClass("cmts-list");

            for (Element clearfix:cmtslist){
                String user =  clearfix.select("a").get(1).text();
                String userPhotoUrl =clearfix.select("img").get(0).attr("src");
                String replyTime = clearfix.select("a").get(3).text();
               String floor=clearfix.select("span").text();

                System.out.println("评论者:"+user+"\n"+"评论者头像url:"+userPhotoUrl+"\n"+"回复时间:"+replyTime+"\n"+"所在楼层:"+floor);
                Document replyContentDoc = Jsoup.parse(clearfix.toString());
               Elements replyContent =  replyContentDoc.getElementsByClass("cmt-content");
                System.out.println("评论内容:");
                int s =replyContent.select("p").size();
               for (int j=0;j<s;j++){
                 String replycontent =   replyContent.select("p").get(j).text();
                   System.out.println(replycontent);


               }
                System.out.println("================================================");
            }

        } catch (IOException e) {
            e.printStackTrace();
        }


    }

}

输出结果:

以上就是小编的demo,写的有点简单,希望理解,233
