Save Search Results of A Search Engine

Question

I'm trying to write an application to perform a search on a search engine automatically (search for a specified phone number on a search box) and get the resulted page as anything (XML, text). I've tried several web crawlers / scrapers but I haven't found something that performs the search and saves the resulted data. They can only get the requested page data which is not what I need.

The language can be C#, VB.Net or Java, it does not matter as long as it provides the solution. Thanks.

I'm looking for a tool or code snippet that does this.

A function like this will extract the data as a string, but you will have to parse the data in it yourself:

Public Shared Function GetWebPageData(ByVal address As Uri) As String
    Dim request As HttpWebRequest
    Try
        request = DirectCast(WebRequest.Create(address), HttpWebRequest)

        Using response As HttpWebResponse = DirectCast(request.GetResponse(), HttpWebResponse)
            Using reader As StreamReader = New StreamReader(response.GetResponseStream())
                Return reader.ReadToEnd
            End Using
        End Using
    Catch ex As Exception
        'TODO handle the error here....
        Return ""
    End Try
End Function

Usage:

Dim xml As String = Networking.GetWebPageData(New Uri("http://www.hitta.se/077-570%2005%2000/f%C3%B6retag_och_personer"))
Debug.WriteLine(xml)
