asp.net - How to avoid System.Xml.Linq.XElement escaping HTML content?

Question

I'm using the XElement object to build some HTML in the code-behind on an ASP.NET page.

I may or may not add some XAttributes to this XElement as I go along, in the following fashion:

var elmnt = new XElement("div",
     new XAttribute("id", "myDiv"),
     );

Now, if I want to add some content into myDiv which contains HTML, the XElement automatically escapes this which, in my situation, is undesirable.

So if I have:

var elmnt = new XElement("div",
     new XAttribute("id", "myDiv"),
     "<span id='content'>hello world</span>"
     );

And then I render this into a Placeholder object using the following code:

myPlaceholder.Controls.Add(new System.Web.UI.WebControls.Literal { Text = elmnt.CreateNavigator().OuterXml });

When the page loads, the source reveals that the inner content inside elmnt has been escaped, and has the following format in the page's source:

<span id='content'>hello world</span>

Given that the XML I'm compiling here is valid HTML, and the inner content is also valid HTML, how can I tell the XElement parent object to not escape the inner content? How can I leave it in its native format?

Answer 1

 var elmnt = new XElement("div",
   new XAttribute("id", "myDiv"),
   new XRaw("<span id='content'>hello world</span>")
 );


public class XRaw : XText
{
  public XRaw(string text):base(text){}
  public XRaw(XText text): base(text){}

  public override void WriteTo(System.Xml.XmlWriter writer)
  {
    writer.WriteRaw(this.Value);
  }
}
