TypeError while working with Nokogiri

Nokogiri returns me a page of code:

As you see there only links with hrefs. And I want get it href content. And if I try to do so:

data1 = data.css("li")
data2 = data1.css("a")

puts data2["href"]

I got an error:

test.rb:93:in `[]': no implicit conversion of String into Integer (TypeError)

Why? Sure I can get href content with simple RegExp. But there is a simple way I see.

When I added:

data2.each { |x|
      puts x["href"]
}

I got the results. Simple. Too simple.
