Preventing Nokogiri from escaping characters?

Question

I have created a text node and inserted into my document like so:

#<Nokogiri::XML::Text:0x3fcce081481c "<%= stylesheet_link_tag 'style'%>">]>

When I try to save the document with this:

File.open('ng.html', 'w+'){|f| f << page.to_html}

I get this in the actual document:

<%= stylesheet_link_tag 'style'%>

Is there a way to disable the escaping and save my page with my erb tags intact?

Thanks!

Answer 1

Perhaps you want to use the "<<" method to insert raw XML like this:

builder = Nokogiri::XML::Builder.new do |b|
  b.html do
    b.head do
      b << stylesheet_link_tag 'style'
    end
  end
end
builder.to_xml

Answer 2

You are obliged to escape some characters in text elements like:

"   "
'   '
<   &lt;
>   &gt;
&   &amp;

If you want your text verbatim use a CDATA section since everything inside a CDATA section is ignored by the parser.

Nokogiri example:

builder = Nokogiri::HTML::Builder.new do |b|
  b.html do
    b.head do
      b.cdata "<%= stylesheet_link_tag 'style'%>"
   end
  end
end
builder.to_html

This should keep you erb tags intact!
