How to remove all children nodes of selected node - html-agility-pack

If you meant to keep only text nodes within the outer <div>, you can select all html child nodes using star XPath selector (*) and remove them. Here is an example in console application :

var html = @"<div class=""Price fs30 clr8"">
   7,
   <span class=""PriceCurrency"">73 TL
   <span class=""kdv"">KDV Dahil</span>
   </span>
   <div class=""SaleDiv"">
      %15
      <span>Ä°ndirim</span>
   </div>
</div>";
var doc = new HtmlDocument();
doc.LoadHtml(html);
var div = doc.DocumentNode.SelectSingleNode("//div[@class='Price fs30 clr8']");
foreach (HtmlNode node in div.SelectNodes("*"))
{
    node.Remove();
}
var innerText = div.InnerText.Trim();
Console.WriteLine(innerText);
