Im trying to create a tool where you just click a button and it will get you the info needed and add it to a listview
From this link:
http://www.internet-radio.com/stations/hardcore/page1
Eg when the website loads it will get the name from the radio station and the wmp link and add it to a listview
Name
Dance Uk Stream Danceradiouk.Com
The link the button with the wmp logo goes to
http://servers.internet-radio.com/tools ... pls&t=.m3u
Anyone have a clue on how i could accomplish this ?

It is unlikely that regex by itself will give the needed functionality.
You can use a WebBrowser control to access the HTML elements.
This sample will list the link names/wmp links from the table on that page:
Code: Select all Private Sub btnTest_Click(sender As System.Object, e As System.EventArgs) Handles btnTest.Click
WebBrowser1.ScriptErrorsSuppressed = True
WebBrowser1.Navigate("http://www.internet-radio.com/stations/hardcore/page1")
End Sub
Private Sub WebBrowser1_DocumentCompleted(sender As System.Object, e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
If e.Url.ToString() = "http://www.internet-radio.com/stations/hardcore/page1" Then
Dim tables As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("table")
Dim rows As HtmlElementCollection = tables(0).GetElementsByTagName("tr")
For i As Integer = 0 To rows.Count - 1
Dim cells As HtmlElementCollection = rows(i).GetElementsByTagName("td")
Dim links As HtmlElementCollection = cells(0).GetElementsByTagName("a")
Dim href As String = links(1).GetAttribute("href")
Dim links2 As HtmlElementCollection = cells(1).GetElementsByTagName("a")
Dim title As String = links2(0).InnerText
ListView1.Items.Add(New ListViewItem(New String() {title, href}))
Next
End If
End Sub
