[Rails] Re: Good Rubyistic way Looking for nokogiri program

Love U Ruby wrote in post #1112338:

> doc.search('div').children.reject(&:text?).map{|n| n.name if
> !n.child.to_str.strip.empty? }.compact
> # => ["dt", "dt", "dd"]

I found one shortest way using `css` rules :

doc.search("dt,dd").map{|n| n.name unless n.to_str.strip.empty?
}.compact
# => ["dt", "dt", "dd"]
