如何使用HTMLAgility选择类rel

Question

<div id="id_language" class="sBody text select_m" rel="1">Français</div>

From this HTML code. I want HTMLAgility or something else to find it.

And next is my code

 while (htmldoc.DocumentNode.SelectNodes("Français") == null)
                {
                    webBrowser1.Document.GetElementById("id_language").Focus();

                    SendKeys.Send("{DOWN}");
                }

In my code, I want to find to keydown until it found "Français" (or rel=1) and then stop. Anyone can help me? Thank you.

Answer 1

So First Francais is the value of your div node. If you want to search for the div Html Node with value Francais. You should have.

var divNode = htmldoc.DocumentNode.Descendants().
                       Where(x => x.Name == "div" && x.InnerText == "Français").
                       FirstOrDefault();

If you want to find the div with attribute rel=1, you should have something like this:

var divNode = htmldoc.DocumentNode.Descendants().
                   Where(x => x.Name == "div" && x.Attributes["rel"].Value == "1").
                   FirstOrDefault();

Answer 2

This might do the trick for you

var french = doc.DocumentNode.SelectSingleNode("//div[@rel]")
var relVal = french.Attributes["rel"].Value;

so you can do

while(htmldoc.DocumentNode.SelectSingleNode("//div[@rel]").Attributes["rel"].Value == "1")
{
    SendKeys.Send("{DOWN}");
}
