visual studio 2010 - Parsing Financial information from HTML -


first attempt @ learning work html in visual studio , c#. using html agility pack library. parsing.

from page attempting pull out numbers "net income" row each quarter.

here current progress, (but uncertain of how proceed further):

        string url = "http://www.google.com/finance?q=nasdaq:txn&fstype=ii"         var webget = new htmlweb();         var document = webget.load(url);         var body = document.documentnode.descendants()                             .where(n => n.name == "body")                             .firstordefault();          if (body != null)         {          }

well, first of there's no need body first, can directly query document want. finding value you're looking for, how it:

htmlnode tdnode = document.documentnode.descendantnodes()   .firstordefault(n => n.name == "td"     && n.innertext.trim() == "net income"); if (tdnode != null) {   htmlnode trnode = tdnode.parentnode;   foreach (htmlnode node in trnode.descendantnodes().where(n => n.nodetype == htmlnodetype.element))   {     console.writeline(node.innertext.trim());     //output:     //net income     //265.00     //298.00     //601.00     //672.00     //666.00   } }

also note trim calls because there newlines in innertext of elements.
