Why does XDocument.Parse throw NotSupportedException?

Question

I am trying to parse xml data using XDocument.Parse wchich throws NotSupportedException, just like in topic: Is XDocument.Parse different in Windows Phone 7? and I updated m

Answer 1

There are special symbols like '&' in e.Result.

I just tried replace this symbols (all except '<', '>', '"') with HttpUtility.HtmlEncode() and XDocument parsed it

UPD:

I didn't want to show my code, but you left me no chance :)

 string y = "";
 for (int i = 0; i < s.Length; i++)
 {
      if (s[i] == '<' || s[i] == '>' || s[i] == '"')
      {
           y += s[i];
      }
      else
      {
           y += HttpUtility.HtmlEncode(s[i].ToString());
      }
 }
 XDocument document = XDocument.Parse(y);
 var options = (from option in document.Descendants("option")
      select option.Value).ToList();

It's work for me on WP7. Please, do not use this code for html conversion. I wrote it quickly just for test purposes
