Htmlagilitypack: create html text node
Question
In HtmlAgilityPack, I want to create HtmlTextNode, which is a HtmlNode (inherts from HtmlNode) that has a custom InnerText.
HtmlTextNode CreateHtmlTextNode(string name, string text)
{
HtmlDocument doc = new HtmlDocument();
HtmlTextNode textNode = doc.CreateTextNode(text);
textNode.Name = name;
return textNode;
}
The problem is that the textNode.OuterHtml and textNode.InnerHtml will be equal to "text" after the method above.
e.g. CreateHtmlTextNode("title", "blabla") will generate:
textNode.OuterHtml = "blabla" instead of <Title>blabla</Title>
Is there any better way to create HtmlTextNode?
Accepted Answer
A HTMLTextNode contains just Text, no tags.
It's like the following:
<div> - HTML Node
<span>text</span> - HTML Node
This is the Text Node - Text Node
<span>text</span> - HTML Node
</div>
You're looking for a standard HtmlNode.
HtmlDocument doc = new HtmlDocument();
HtmlNode textNode = doc.CreateElement("title");
textNode.InnerHtml = HtmlDocument.HtmlEncode(text);
Be sure to call HtmlDocument.HtmlEncode() on the text you're adding. That ensures that special characters are properly encoded.

The following lines creates a outer html with content
var doc = new HtmlDocument();
// create html document
var html = HtmlNode.CreateNode("<html><head></head><body></body></html>");
doc.DocumentNode.AppendChild(html);
// select the <head>
var head = doc.DocumentNode.SelectSingleNode("/html/head");
// create a <title> element
var title = HtmlNode.CreateNode("<title>Hello world</title>");
// append <title> to <head>
head.AppendChild(title);
// returns Hello world!
var inner = title.InnerHtml;
// returns <title>Hello world!</title>
var outer = title.OuterHtml;
Hope it helps.
