Get href HTML attribute in C#

I have the following code in a Razor view:

<div id="HTMLreturned" class="row">

   @Html.Raw(ViewBag.HTMLreturned);

 </div>

<script>

        var nrLinks = 0;

        $(".enlacesMas > a").each(function(){

            nrLinks++;
            var link = "http://www.meu.site" + $(this).attr('href').replace("..","");

            // Agora preciso de guardar todos os link num array ou algo do género


        });


</script>

In the controller put in the Viewbag.Htmlreturned the result of this line:

ViewBag.HTMLreturned = WebClient.client.DownloadString(meuUrl)

How can I run my code view in my controller to keep each href in variable C#?

Obs:

The html which jQuery works with is rendered before the script is executed, so these classes are from html within the viewbag

    What do you mean, young man? Explain better what you want to do.

  • @jbueno I think it’s clearer now

  • After running each, you want to store all href in an array and return it to a controller. This?

  • @Aline, I don’t want to have a viewat all, I want to do it all in controller

  • Yeah, I didn’t quite understand.

  • I realized now that what I wanted to do is not going to be possible, basically what I need now to turn this jQuery code into code c#

  • Can you explain why you wanted to use backend code instead of Jquery? What was your use case?

  • I had a string that was an html, and I wanted to extract information from it using a language like jQuery, because I already know some techniques

I was able to get exactly the same result in C# by installing the Csquerylatest with Nuget, and writing the following code:

 string htmlCode = "";
        List<string> links = new List<string>();

        using (WebClient client = new WebClient())
        {
            htmlCode = client.DownloadString("https://www.boe.es/buscar/anboe.php?campo%5B0%5D=TIT&dato%5B0%5D=&operador%5B0%5D=and&campo%5B1%5D=ID_DEM&dato%5B1%5D=&operador%5B1%5D=and&campo%5B2%5D=DOC&dato%5B2%5D=&operador%5B2%5D=and&campo%5B3%5D=ID_TIP&dato%5B3%5D=&operador%5B3%5D=and&campo%5B4%5D=GEO&dato%5B4%5D=&operador%5B4%5D=and&campo%5B5%5D=DOC&dato%5B5%5D=&operador%5B6%5D=and&campo%5B6%5D=FPU&dato%5B6%5D%5B0%5D=02%2F01%2F2017&dato%5B6%5D%5B1%5D=02%2F01%2F2017&page_hits=200&sort_field%5B0%5D=FPU&sort_order%5B0%5D=desc&sort_field%5B1%5D=ref&sort_order%5B1%5D=asc&accion=Buscar");
            var query = CQ.Create(htmlCode);
            var rows = query[".enlacesMas a"];
            foreach (var row in rows)
            {
                var newLink = row.Attributes["href"];
                links.Add(newLink);
                // aqui guardo todos os link numa lista
            }

        }
