Nokogiri Node Set

I am trying to use Nokogiri to scrape a web page. Right now, I am able to set a variable links to the following on a web page:

links = page.css('.item_inner')

and links is a:

Nokogiri::XML::NodeSet

Then I iterate through this NodeSet(links):

links.each{|link| puts link.css('.details a')}

In order to get some more information. But now the method above's class is now a:

Fixnum

and returns a list of (I'm not sure exactly what they are returning but it looks like a list of these:

<a se:clickable:target="true" href="/nyc/sale/1056207-coop-150-sullivan-street-soho-new-york?featured=1">150 Sullivan Street #34</a>

Now I know that there are key/value pairs within this but I am unable to access them at this point. How can I access say the href here and the actual name?

Once you have a single link as a node, its href is link['href'] and so forth, and the link text ("150 Sullivan Street") is its content.

NOTE: A css search always yields what is effectively an array of found nodes (actually a NodeSet). If you are quite sure that there is only one of something to be found by your search, you can skip past that by using at_css instead, thus yielding a single node.
