how to get value of a node in nokogiri

Question

I have this

1.9.3-p286 :073 > doc.css("tr[class~=strong]").children[3].children
 => [#<Nokogiri::XML::Element:0x3fee5e077e98 name="a" attributes=[#
      <Nokogiri::XML::Attr:0x3fee5e077dd0 name="href" 
      value="http://somelink">]>] 

Sample html:

<tr class='strong bf highbeam'>
  <td>December 6th</td>
  <td>Foo</td>
  <td><a href='http://somelink' title='bar'>December 6th 2012 Episode</a></td>
  <td><a href='http://somelink/#disqus_thread'></a></td>
</tr>

How can I fetch the value http://somelink at this point?

不要使用children ，优化CSS选择器，直到获得所需的元素：

doc.at('tr.strong a')[:href]
