Flexirest: XML Responses

Flexirest uses Crack to allow parsing of XML responses. For example, given an XML response of (with a content type of application/xml or text/xml):

<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom">

  <title>Example Feed</title>
  <link href="http://example.org/"/>
  <updated>2003-12-13T18:30:02Z</updated>

  <entry>
    <title>Atom-Powered Robots Run Amok</title>
    <link href="http://example.org/2003/12/13/atom03"/>
    <id>urn:uuid:1225c695-cfb8-4ebb-aaaa-80da344efa6a</id>
    <updated>2003-12-13T18:30:02Z</updated>
    <summary>Some text.</summary>
  </entry>

  <entry>
    <title>Something else cool happened</title>
    <link href="http://example.org/2015/08/11/andyjeffries"/>
    <id>urn:uuid:1225c695-cfb8-4ebb-aaaa-80da344efa6b</id>
    <updated>2015-08-11T18:30:02Z</updated>
    <summary>Some other text.</summary>
  </entry>

</feed>

You can use:

class Feed < Flexirest::Base
  base_url "http://www.example.com/v1/"
  get :atom, "/atom"
end

@atom = Feed.atom

puts @atom.feed.title
puts @atom.feed.link.href
@atom.feed.entry.each do |entry|
  puts "#{entry.title} -> #{entry.link.href}"
end

For testing purposes, if you are using a fake content response when defining your endpoint, you should also provide fake_content_type: "application/xml" so that the parser knows to use XML parsing.
