Parse OPML into a flat hash. OPML Saw supports nesting (folders) through the tag attribute. the most immediate parent of the outline will become the tag.
Add this line to your application's Gemfile:
gem 'opml_saw', :git => "git://github.com/feedbin/opml_saw.git", :branch => "master"
And then execute:
$ bundle
Or install it yourself as:
$ gem install opml_saw
subscriptions.xml
<?xml version="1.0" encoding="UTF-8"?>
<opml version="1.0">
<head>
<title>Subscriptions</title>
</head>
<body>
<outline text="Riding Rails - home" title="Riding Rails - home" type="rss" xmlUrl="http://feeds.feedburner.com/RidingRails" htmlUrl="http://weblog.rubyonrails.org/"/>
</body>
</opml>file = File.open('subscriptions.xml', 'r')
contents = file.read
opml = OpmlSaw::Parser.new(contents)
opml.parse
pp opml.feeds
