visual studio 2010 - VB.NET - How do I search through Webpage source for particular div and output inside txt as msgbox? -

vb.net - how search through webpage source particular div , output inside txt msgbox?

so far can download webpage's source code. don't know how search through particular string of information.

code far:

dim source string = new  system.net.webclient().downloadstring("http://pagewantingtouse.com") 

the division called "description", i'm after information within it. want output message-box.

example below:

<div class="description">         amazing spider-man 2012 american superhero film based on marvel  comics character spider-man. fourth installment of spider-man film series, serving  reboot. </div> 

i had laying around project did. takes page , stream reads web browser, , pulls out whatever want it. looked @ reading string before, problem me, @ least, had find length between tags, etc. worked me:

 dim request webrequest = webrequest.create("http://pagewantingtouse.com") 'create web request html file     using response webresponse = request.getresponse() 'get response request         using reader new streamreader(response.getresponsestream) 'identify how want read response , assign streamreader             dim webtext string = reader.readtoend() 'read response (web page) string end of file   dim wbc webbrowser = new webbrowser() 'create web browser handle data. sift through              wbc.documenttext = ""              wbc.document                 .opennew(true)                 .write(webtext) 'write web page response web browser control                   dim itemlist htmlelementcollection = .getelementsbytagname("div")                      each item in itemlist 'look @ each item in collection                     if item.classname = "description"                          msgbox item.innertext 'this msgbox description                     exit 'exit once found                     end if                    next 'do every item in collection until find              end           wbc.dispose()          end using      end using  

if want tell me page, can update code, should @ least answer question.
