var document = parser.LoadDocument( "http://www.cnblogs.com/" );
 
var elements = document.Find( "#post_list > .post_item" );
foreach ( var e in elements )
{
  Console.WriteLine( "title: {0}", e.FindFirst( "h3 > a" ).InnerText() );
  Console.WriteLine( "link: {0}", e.FindFirst( "h3 > a" ).Attribute( "href" ).Value() );
  Console.WriteLine( "votes: {0}", e.FindFirst( ".diggnum" ).InnerText() );
  Console.WriteLine( "author: {0}", e.FindFirst( ".post_item_foot a.lightblue" ).InnerText() );
  Console.WriteLine( new string( '-', 30 ) );
