如何在Ruby中编码/解码HTML实体？ [英] How do I encode/decode HTML entities in Ruby?

问题描述

我试图解码一些HTML实体，例如'& lt;'变成'<'

我有一个老宝石（ html_helpers ），但它似乎已被放弃两次。

任何建议？我将需要在模型中使用它。

解决方案

HTMLEntities 可以做到这一点：

 ：jmglov @ laurana; sudo gem install htmlentities 
成功安装htmlentities-4.2.4 
：jmglov @ laurana; irb 
 irb（main）：001：0>要求'htmlentities'
 => [] 
 irb（main）：002：0> HTMLEntities.new.decode& iexcl;我很高兴并且带有人物参考！ 
 => 我非常讨厌角色参考！ 
  

I am trying to decode some HTML entities, such as '<' becoming '<'.

I have an old gem (html_helpers) but it seems to have been abandoned twice.

Any recommendations? I will need to use it in a model.

解决方案

HTMLEntities can do it:

: jmglov@laurana; sudo gem install htmlentities
Successfully installed htmlentities-4.2.4
: jmglov@laurana;  irb
irb(main):001:0> require 'htmlentities'
=> []
irb(main):002:0> HTMLEntities.new.decode "¡I'm highly annoyed with character references!"
=> "¡I'm highly annoyed with character references!"
