[Code] Parse all runescape worlds from website!

Well, at least it used to be able to do it. This is the code i used to parse runescape website before they made an update and turned it all into javascript. I've parsed the new one, but i'm giving out my old code in an attempt to teach you all about string manipulation. Here it is:

Code:

    Dim html_parser As New MIL.Html.HtmlDomainTreeParser()
    Dim html_document As New MIL.Html.HtmlDocument
    Dim html_node As MIL.Html.HtmlNode
    Dim html_nodelist As New MIL.Html.HtmlNodeCollection

Code:

    Public Sub grabWorldsOld()

        Dim tmp() As String
        Dim worldType As String = Nothing
        Dim worldPrefix As String = Nothing
        Dim worldNumber As String = Nothing

        If My.Computer.FileSystem.FileExists(My.Application.Info.DirectoryPath & "\worldlist.lst") Then
            My.Computer.FileSystem.DeleteFile(My.Application.Info.DirectoryPath & "\worldlist.lst")
        End If

        Dim out As New IO.StreamWriter(My.Application.Info.DirectoryPath & "\worldlist.lst")
        Dim htmlgrabber As New Net.WebClient()
        html_document = html_parser.Parse(htmlgrabber.DownloadString("http://www.runescape.com/sl.ws?lores.x=420&plugin=0&order=WLPM"))
        html_nodelist = html_document.Nodes.FindAllElements(True)

        For Each html_node In html_nodelist
            If html_node.HTML.Contains("<tr>") And html_node.HTML.Contains("</tr>") And Not html_node.HTML.Contains("</div>") And Not html_node.HTML.Contains("<table") Or html_node.HTML.Contains("<tr class=" & Chr(34) & "r2" & Chr(34) & ">") And html_node.HTML.Contains("</tr>") And Not html_node.HTML.Contains("</div>") And Not html_node.HTML.Contains("<table") Then
                'Getting World Number
                worldNumber = html_node.HTML.Substring(InStr(html_node.HTML(), "World") + 5)
                tmp = worldNumber.Split("<")
                worldNumber = tmp(0).Trim()
                tmp = Nothing

                'Getting World Prefix
                If html_node.HTML.Contains("http") Then
                    tmp = html_node.HTML.Split(".")
                    tmp = tmp(0).Split("/")
                    worldPrefix = tmp(2)
                    tmp = Nothing
                Else
                    worldPrefix = "Full"
                End If


                'Getting World Type
                If html_node.HTML.Contains("<td class=" & Chr(34) & "m" & Chr(34) & ">") Then
                    worldType = "members"
                ElseIf html_node.HTML.Contains("<td class=" & Chr(34) & "f" & Chr(34) & ">") Then
                    worldType = "free"
                End If
                out.WriteLine(worldNumber & "," & worldPrefix & "," & worldType)
            End If
        Next
        out.Close()
        MsgBox("Success! All worlds have been parsed.")
    End Sub

To use that html parser, you will need to reference the file i've attached.

Enjoy
