How do I use Sinatra to serve XML documents?

Question

I have some XML documents that I'd like to server from Sinatra. I did some searching but couldn't find anything specific. I did find the builder gem but I don't want to build the document from scratch.

I tried to do something like this

get '/'
  xml = '<?xml version=\"1.0\" encoding=\"UTF-8\"?> <name>My name</name> <age>90</age>'
  body xml
end

but that will add the HTML tags around it. It's probably something really basic I'm missing. Can you point me in the right direction please?

What is your expected output of get '/' xml = "My name 90" body xml? — BlueDog, Nov 19 '10 at 17:52

This is very simple with Sinatra:

get '/' do
  content_type 'text/xml'
  "<name>Luis</name><age>99</age>"
end

On get '/' the response will be the XML "<name>Luis</name><age>99</age>" with the correct content_type.

I knew it was something simple... Should've thought of that! – Luis Nov 19 '10 at 18:32

This answer is no completely right and have an exception on the Sinatra level. XML should have only one root element: http://www.w3schools.com/xml/xml_syntax.asp – naviram Jul 01 '16 at 14:40

As answered below, in addition Wagner's answer of adding the content type, you must include only one XML root element http://www.w3schools.com/xml/xml_syntax.asp otherwise Sinatra will raise an exception.

So the complete answer is:

get '/'
  content_type 'text/xml'
  '<?xml version=\"1.0\" encoding=\"UTF-8\"?><root><name>My name</name> <zage>90</age></root>'
end
