I'm using HTML Agility Pack to parse and transform a HTML file, but I get an exception "Item has already been added" when try to create a new HTMLNode because of the index parameter.
HtmlNode node1 = new HtmlNode(HtmlNodeType.Element, doc, 0); node1.Name = "div"; HtmlNode node2 = new HtmlNode(HtmlNodeType.Element, doc, 0); node2.Name = "div";
This is how you can create a node (it basically mimics System.Xml semantics, on purpose):
HtmlNode div = doc.CreateElement("div"); myNode.Append(div);
I don't know about this constructor you use, maybe a new one available in version 1.4?
