Retrive html content using System.Net.HttpWebRequest Romania
  • 10 years ago


    I want to retrive some html content from a given website. For that I use the System.Net.HttpWebRequest:

    Dim connectionString As String = "some url here"

    Dim myRequest As
    System.Net.HttpWebRequest = WebRequest.Create(connectionString)
                myRequest.Credentials = CredentialCache.DefaultCredentials

    '// Get the response

       Dim webResponse As WebResponse = myRequest.GetResponse
       Dim respStream As Stream = webResponse.GetResponseStream


       Dim ioStream As StreamReader = New StreamReader(respStream)
       Dim pageContent As String = ioStream.ReadToEnd


    '// Close streams

    Catch ex As Exception
            Me.Label1.Text = ex.Message

    End Try


    The above code works, but the problem is that it retrieves all the html content...and I don't nee it all.

    All I need is all the content between <head> and </head>

    Just parse the html and take what's between the head tags.

    The nature of the request is that you can't specify that you want just the head tags, because the server always sends the full data when it gets a request.

    Hi pcmattman, and thank you for the reply!

    I thought about what you've said myself, but there is a problem...I don't know how to do it Sad [:(]...

    I've searched the net and I couldn't find an example on how to do it...They were only showing the way of retrieving all the content and not parts of it.

    I'm a seo consultant and a web designer. I always liked VB but my knowledge is limited though...
    (I use programming only when I have to)

    Maybe you can help me providing a sample code, please?


    [ I should start learn more...]
