HTTPWEBREQUEST Extract URLS or Links.....

I would like to use the httpwebrequest to pull all the links from my blog. I would like for the links to be extracted and sent to a textbox1.text from the httpwebrequest method.

Here's the example that I have to extract all the html source code, but all I need is the URLs from my web page:

Try
TextBox1.Text = ""
Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("http://membersofilluminati.blogspot.com/")
Dim response As System.Net.HttpWebResponse = request.GetResponse()
Dim sr As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream())
Dim sourcecode As String = sr.ReadToEnd()
TextBox1.Text = sourcecode
Catch ex As Exception
End Try


Could someone please show me how to convert this to extract/parse only links or URLs from the web page and send it to Textbox1.text???


Thanks...

This will extract all http:// links from the webpage.

vb.net Code:

Imports System.Text.RegularExpressions
Imports System.Net
Imports System.Text
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim sb As New StringBuilder
        Dim html As String
 
        Using wc As New WebClient
            html = wc.DownloadString("http://membersofilluminati.blogspot.nl/")
        End Using
 
        Dim regx As New Regex("http://([\w+?\.\w+])+([a-zA-Z0-9\~\!\@\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\,]*)?", RegexOptions.IgnoreCase)
        Dim matches As MatchCollection = regx.Matches(html)
 
        For Each match As Match In matches
            sb.AppendLine(match.Value)
        Next
 
        TextBox1.Text = sb.ToString
    End Sub
