Ruby's built-in URI does this already:

From extractdocs:

require "uri"

URI.extract("text here http://foo.example.org/bla and here mailto:test@example.com and here also.")
# => ["http://foo.example.com/bla", "mailto:test@example.com"]

require 'uri'

text = %{"test
<a href="http://www.a.com/">http://www.a.com/</a>, and be sure
to check http://www.a.com/blog/. Email me at <a href="mailto:b@a.com">b@a.com</a>.}


END_CHARS = %{.,'?!:;}
p URI.extract(text, ['http']).collect { |u| END_CHARS.index(u[-1]) ? u.chop : u }
