Jsoup解析Html标签(Java后台解析)

　　

　　中文API网站(下载地址):　http://www.open-open.com/jsoup/　

　　有时候编辑器传到后台的内容是带Html标签的，或者有时候需要形成一个完整的Html文档，也或者需要解析其中的文字(text()),Java后台处理用Jsoup非常方便，也可以用选择器快速获取元素，类似于jQuery。获取到文档对此之后对其处理与JS处理DOM一样方便，选取元素也类似于JS，也有类似于jQuery的语法，官方的解释

1.最基本的解析Html字符串

    @Test
    public void testHtmlToString2() {
        String html = "<p>这是一个段落<img src=\"test.img\"/>内容;</p>";
        Document doc = Jsoup.parse(html);
        System.out.println(doc); // 输出带标签的html文档
        System.out.println("---------------------\n"+doc.text()); // 输出内容
        Elements element = doc.getElementsByTag("p");
        System.out.println("---------------------\n"+element.get(0).html());
    }

结果:

<html>
 <head></head>
 <body>
  <p>这是一个段落<img src="test.img">内容;</p>
 </body>
</html>
---------------------
这是一个段落内容;
---------------------
这是一个段落<img src="test.img">内容;

2.解析字符串

    // 解析html字符串
    @Test
    public void testHtmlToString() {
        String html = "<html><head><title>First parse</title></head>"
                + "<body><p style=‘center‘>Parsed HTML into a doc.</p></body></html>";
        Document doc = Jsoup.parse(html);
        System.out.println(doc); // 输出带标签的html文档
        System.out.println("---------------------\n"+doc.text()); // 输出内容
    }

结果:

<html>
 <head>
  <title>First parse</title>
 </head>
 <body>
  <p style="center">Parsed HTML into a doc.</p>
 </body>
</html>
---------------------
First parse Parsed HTML into a doc.

3.// 解析body片段

    @Test
    public void test2() {
        String html = "<div><p>Lorem ipsum.</p>";
        Document doc = Jsoup.parseBodyFragment(html);
        System.out.println(doc);
        System.out.println(doc.text());
    }

结果:

<html>
 <head></head>
 <body>
  <div>
   <p>Lorem ipsum.</p>
  </div>
 </body>
</html>
Lorem ipsum.

4.// 解析一个url与用选择器选择元素(相当于查看源码)

    @Test
    public void test4() throws IOException {
        Document doc = Jsoup.connect("http://qiaoliqiang.cn:8080/").get();
        String title = doc.title();// 获取title
        System.out.println(title);
        System.out.println("---------------------\n"+doc.toString()+"---------------------\n");// 输出文档全部
        Elements links = doc.getElementsByTag("a");
        for (Element ele : links) {
            System.out.println(ele.toString());
        }
    }

Jsoup解析Html标签(Java后台解析)的相关文章

Java后台解析android端发送的JSON字符串

在设备通讯中,往往会用到数据交互.我们这里用的是通过HTTP协议发送JSON数据,android客户端把数据进行打包,发送到后台服务器,后台解析出来. //android客户端拼装JSON字符串 //如下的拼装结果为: {"data":[{"id":"12345","name":"张三"},{"id":"54321","name":"李四

java 后台解析excel上传数据 工具类

后台调用: MultipartFile file: List<String[]> excelDate package com.holike.crm.partner.sys; import java.io.IOException; import java.io.InputStream; import java.util.ArrayList; import java.util.List; import org.apache.log4j.Logger; import org.apache.poi.h

jsoup: Java HTML 解析器

jsoup 是一款Java 的HTML解析器,可直接解析某个URL地址.HTML文本内容. 请参考:jsoup.org 例如: beanshell 抓取CSDN极客头条内容  soup.bsh // package org.jsoup.examples; import org.jsoup.Jsoup; import org.jsoup.helper.Validate; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element;

使用 jsoup 对 HTML 文档进行解析和操作

jsoup 简介 Java 程序在解析 HTML 文档时,相信大家都接触过 htmlparser 这个开源项目,我曾经在 IBM DW 上发表过两篇关于 htmlparser 的文章,分别是:从 HTML 中攫取你所需的信息和 扩展 HTMLParser 对自定义标签的处理能力.但现在我已经不再使用 htmlparser 了,原因是 htmlparser 很少更新,但最重要的是有了 jsoup . jsoup 是一款 Java 的 HTML 解析器,可直接解析某个 URL 地址.HTML 文本内

Java数据解析---PULL

安卓和JAVA解析xml文件的三种方式: 1.PULL解析 2.SAX解析 3.DOM解析 三者各有所长,依情况选择解析方式 1.PULL和SAX均采用流式解析,意味着只能从头读到底,无法像DOM解析一样随机访问xml文件中的任意一个节点 2.PULL和SAX占用更少的内存解析,更适用于安卓上的解析xml文件 3.DOM解析时将文件全部解析完,最后让用户任意取特定的信息 ---------------------------------------------------------------

JSP页面中使用JSTL标签出现无法解析问题解决办法

今天建立一个JavaWeb工程测试JNDI数据源连接,在jsp页面中引入了JSLT标签库,代码如下: 1<%@ page language="java"import="java.util.*"pageEncoding="UTF-8"%> 2<%@ taglib uri="http://java.sun.com/jsp/jstl/core"prefix="c"%> 3<%@ ta

Java泛型解析(03)：虚拟机执行泛型代码

Java泛型解析(03):虚拟机执行泛型代码 Java虚拟机是不存在泛型类型对象的,所有的对象都属于普通类,甚至在泛型实现的早起版本中,可以将使用泛型的程序编译为在1.0虚拟机上能够运行的class文件,这个向后兼容性后期被抛弃了,所以后来如果用Sun公司的编译器编译的泛型代码,是不能运行在Java5.0之前的虚拟机的,这样就导致了一些实际生产的问题,如一些遗留代码如何跟新的系统进行衔接,要弄明白这个问题,需要先了解一下虚拟机是怎么执行泛型代码的. 虚拟机的一种机制:擦除类型参数,并将其替换成特

Java数据解析---SAX

一.Sax解析 是从头到尾逐行逐个元素读取内容,修改较为不便,但适用于只读的大文档. Sax采用事件驱动的方式解析文档.简单点说,如同在电影院看电影一样,从头到尾看一遍就完了,不能回退(Dom可来来回回读取) 在看电影的过程中,每遇到一个情节,一段泪水,一次擦肩,你都会调动大脑和神经去接收或处理这些信息 同样,在Sax的解析过程中,读取到文档开头.结尾,元素的开头和结尾都会触发一些回调方法,你可以在这些回调方法中进行相应事件处理 这四个方法是:startDocument() . endDocum
