在Rails中将HTML添加到我的RSS / Atom提要

The default rails XML builder escapes all HTML, so something like:

默认的rails XML构建器会转义所有HTML,因此类似于:

atom_feed do |feed|  
  @stories.each do |story|  
    feed.entry story do |entry|   
      entry.title story.title
      entry.content "<b>foo</b>"
    end  
  end  
end

will produce the text:

将产生文字:

<b>foo</b>

instead of: foo

而不是:foo

Is there any way to instruct the XML builder to not escape the XML?

有没有办法指示XML构建器不转义XML?

3 个解决方案

#1

turns out you need to do

结果你需要做

entry.content "<b>foo</b>", :type => "html"

althought wrapping it in a CDATA stops it working.

虽然将它包装在CDATA中会阻止它工作。

#2

entry.content "type" => "html" do
    entry.cdata!(post.content)
end

#3

The special XML characters <, >, and & are converted to <, > and & automatically. Use the << operation to insert text without modification.

特殊的XML字符<,>和&将自动转换为<,>和&。使用< <操作插入文本而不进行修改。< p>
