whats the wrong in my regex

For that u need to write an application .
In the below function will take url as input and give the total webpage content  as output.
after that u need to find a unique search for capturing what u need.

    Public Function user_webrequest_current(ByVal URL1 As String) As String

        Try

            Dim request1 As WebRequest = WebRequest.Create(URL1)

            Dim response1 As WebResponse = request1.GetResponse()

            Dim reader1 As StreamReader = New StreamReader(response1.GetResponseStream())

            Dim gethtmlcode1 As String

            gethtmlcode1 = reader1.ReadToEnd

            user_webrequest_current = gethtmlcode1

        Catch e As Exception

            user_webrequest_current = ""

            MsgBox(e.Message, MsgBoxStyle.OKOnly, "current News")

            Application.Exit()

        End Try

    End Function

See WebRequest and WebResponce class for this.
Here is a sample code to retreive the page content from window form.
After this you have to parse the data you required.

public Form1()
{
InitializeComponent();
WebRequest webRequest = WebRequest.Create(“http://www.yahoo.com”);
WebResponse webResponse = webRequest.GetResponse();
Stream stream = webResponse.GetResponseStream();
StreamReader streamReader = new StreamReader(stream);
string line;
while ( (line = streamReader.ReadLine()) != null)
{
listBox1.Items.Add(line);
}
stream.Close();
}
