私は HTML アジリティ パックを使用しています...[星の間] のみのアドレスを抽出したい..どのような構文が必要ですか?? 親切に助けてください。

更新:次のコードを使用しています

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim webGet = New HtmlWeb()
        Dim document = webGet.Load("http://www.justdial.com/Guwahati/Bachelor-Cake/ct-10070075")

        Dim nodes1 = document.DocumentNode.SelectNodes("//*[@class='logoDesc']")

        For Each node In nodes1
            MsgBox(node.InnerText)
        Next node
    End Sub

このコード スニペットを使用して、div 内のすべての詳細を取得します...アドレスだけが必要です。

Answer 1

これを試してください（XPathの最後に「/ text（）」を追加します）：

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim webGet = New HtmlWeb()
    Dim document = webGet.Load("http://www.justdial.com/Guwahati/Bachelor-Cake/ct-10070075")
    Dim nodes1 = document.DocumentNode.SelectNodes("//*[@class='logoDesc']/text()")
    For Each node In nodes1
        MsgBox(node.InnerText)
    Next node
End Sub

Answer 2

No idea on agility pack, but here's a straight up screen scraper:

    string page = Methods.GetPage("http://www.yoururl.com");
    int firstStars = page.IndexOf("***");
    string second = page.Substring(firstStars);
    int secondStars = second.IndexOf("***");

    //Add 3 to skip over the first three stars. May not need the +3, can't recall.
    string address = page.Substring(0 + 3, secondStars);


    public static string GetPage(string url)
    {
        WebClient webClient = new WebClient();
        byte[] reqHTML;
        string page = string.Empty;

        UTF8Encoding objUTF8 = new UTF8Encoding();
        try
        {
            reqHTML = webClient.DownloadData(url);
            page = objUTF8.GetString(reqHTML);
        }
        catch (Exception theex)
        {

        }
        return page;
    }
