Best way to delete elements from two arrays using delete_if

I was wondering if this can be improved upon.

I have two arrays: links and archived_releases. links contains strings, that might appear in the :url key of an archived_releases entry.

This didn't work:

links.delete_if { |link|
  archived_releases.count > archived_releases.delete_if{ |release| release[:url] == link }.count
}

So I came up with this:

links.delete_if { |link|
  archived_releases.count > archived_releases.delete_if{ |release| release[:url] == link }.count
}

I would first pull out the archived_releases entries you want to quickly compare and then you can just use a quick include? check. Something like:

urls = archived_releases.collect { |ar| ar[:url] }
links.delete_if { |link| urls.include?(link) }
