Subject: [ruby-talk:14167] Ruby way to delete entries from an array

I have an array where I need to delete several entries.
Here is how I am doing it.

a = ["cat\n", "dog\n", "bird \n"]
rm = ["cat", "bird"]

rm.each do |del|
  for i in (0...a.size).collect.reverse
    a.delete_at(i) if /#{del}/ =~ a[i]
  end
end

Is there a more compact way to do this?
