Apache概述:在解析之前处理DOM

问题描述

我想从页面响应中删除特定元素，然后再将其付诸实践.具体来说，我想在网页的某些部分加上标记，例如

I want to remove specific elements from the page response, before it is handed down to nutch.Specifically, I want to mark parts of my pages with i.e.

 <div class="noindex">I shall not be indexed</div>

并希望在进行小节分析之前将其删除，以便随后在NutchDocument中不出现我不会被索引".我计划以此围绕导航，页眉，页脚内容，因为现在，它们出现在索引中的每个文档中.

And want to remove them before nutch parse, so that "I shall not be indexed" is not present in the NutchDocument afterwards. I plan die surround my navigation, header, footer content with this because right now, they are present in every document in the index.

谢谢，保罗

推荐答案

您可以使用一些替代方法:

You have some alternativer for doing that:

• 您可以为此编写一个插件.该博客提供了一个执行示例的完整示例: http://sujitpal.blogspot.com/2009/07/nutch-custom-plugin-to-parse-and-add.html

使用提取器内容:此处 http://tomazkovacic. com/blog/122/evaluating-text-extraction-algorithms/有一些算法.也许做这件事的最好方法也是在胡说八道.

Using an extractor content: Here http://tomazkovacic.com/blog/122/evaluating-text-extraction-algorithms/ have some algorithmics. Maybe the best way of doing that it´s also in a pluggin in nutch.
