How to read the external page title?

Question

I think this is possible with jQuery, but any ASP.NET server code is good for my situation.

With jQuery, I can load a page, for example, into a div, and filter out the div for the tag <title>, but I think it is not good for heavy pages to read all the content first and then read the title tag .. or maybe this is a very simple solution? In any case, I could not find anything about it from the Internet. thanks

Answer 1

Ok thanks to cjjer and Boo, I just read more about regex, and finally the code works for me.

Dim qq As New System.Net.WebClient
    Dim theuri As New Uri(TextBox1.Text)
    Dim res As String = qq.DownloadString(theuri)
    Dim re As Regex = New Regex("<title\b[^>]*>(.*?)</title>", RegexOptions.Singleline)
    Dim ma As Match = re.Match(res)


    If Not ma Is Nothing And ma.Success Then
        Response.Write(ma.Groups(1).Value.ToString())
    Else
        Response.Write("error")
    End If

Match tMatch = new RegEx(@"<title>(?<Content>.*?)?</title>").Match(new System.Net.WebClient().DownloadString(url));

if ((null != tMatch) && (tMatch.IsSuccess)) {
    //  yay.
    title = tMatch.Groups("Content").value;
}
