Java HTML解析

问题描述

我正在研究一个从网站上抓取数据的应用程序，我想知道如何获取数据。具体而言，我需要包含在使用特定CSS类的多个div标签中的数据 - 目前（用于测试目的）我只是检查

 <$在每一行HTML中使用c $ c> div class =classname
  

不禁感到有更好的解决方案。

有没有什么好的方法可以让一个类有一行HTML，并且有一些漂亮的方法：

  boolean usesClass（String CSSClassname）; 
 String getText（）; 
 String getLink（）; 
  

解决方案

几年前，我用JTidy来达到同样的目的：

http://jtidy.sourceforge.net/ b
$ bJTidy是HTML Tidy的一个Java端口，它是一种HTML语法检查器和漂亮的打印机。与其非Java表兄弟类似，JTidy可以用作清理工具修复格式不正确和错误的HTML，另外，JTidy为正在处理的文档提供了一个DOM接口，这使得您可以使用JTidy作为真实世界HTML的DOM解析器。

JTidy是由Andy Quick撰写的，后者从维护者的职位上退出。现在JTidy由一群志愿者维护。

更多关于JTidy的信息可以在JTidy SourceForge项目页面找到。

I'm working on an app which scrapes data from a website and I was wondering how I should go about getting the data. Specifically I need data contained in a number of div tags which use a specific CSS class - Currently (for testing purposes) I'm just checking for

div class = "classname"

in each line of HTML - This works, but I can't help but feel there is a better solution out there.

Is there any nice way where I could give a class a line of HTML and have some nice methods like:

boolean usesClass(String CSSClassname);
String getText();
String getLink();

解决方案

Several years ago I used JTidy for the same purpose:

http://jtidy.sourceforge.net/

"JTidy is a Java port of HTML Tidy, a HTML syntax checker and pretty printer. Like its non-Java cousin, JTidy can be used as a tool for cleaning up malformed and faulty HTML. In addition, JTidy provides a DOM interface to the document that is being processed, which effectively makes you able to use JTidy as a DOM parser for real-world HTML.

JTidy was written by Andy Quick, who later stepped down from the maintainer position. Now JTidy is maintained by a group of volunteers.

More information on JTidy can be found on the JTidy SourceForge project page ."
