Rails String in View with whitespaces

I'm trying to show a string with xml content (correct with whitespaces etc.) in a rails view.

My Controller action read a xml file and put this content into a string. For example 

  @xml_content = "
     <main>
      <children>
         <a>
         </a>
         <b>
         </b>
      </children>
    </main>
    "

Then I get this string from my controller and want to show this xml content in a view.

<%= @xml_content %>

But when I print this string in the view all whitespaces get lost and I get something like this: 

     <main><children><a></a><b></b></children></main>

Printing the same string in the console with "puts @xml_content" create the correct output.

What can I do to show this xml content with all whitespaces in the view?

EDIT: Controller:

@file = File.open(@xml_device_description.get_file_path)

@xml_content = Nokogiri::XML @file

To conserve whitespaces of your content, you can wrap it in a pre tag.

<pre>
 <%= @xml_content %>
</pre>
