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

我正在尝试解码一些 HTML 实体，例如 '<' 变成 '<'.

我有一个旧 gem (html_helpers)，但它似乎已被废弃两次.>

有什么推荐的吗?我需要在模型中使用它.

解决方案

HTMLEntities 可以做到:

: jmglov@laurana;sudo gem 安装 htmlentities成功安装 htmlentities-4.2.4: jmglov@laurana;irbirb(主):001:0>需要'htmlentities'=>[]irb(main):002:0>HTMLEntities.new.decode "&ieexcl;我'非常 对字符引用感到恼火！"=>¡我对角色参考非常恼火！"

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!"
