Fix html & xml feeds encoding

Are there any quick methods that don't require external libraries that can fix webresponse encodings back to the original text. (I'm not sure if the encoding is the actual cause or if my terminology is correct here?)

As an example, my code below returns the first line but I need the second line. So doc.InnerXML reads:

<description>S&amp;P500</description> //What I get <description>S&P500</description> //What I want 

I was looking for a generic solution that would fix all instances such as spaces, apostrophes, ampersand etc.

The html agility pack seems a bit overkill for this and was hoping there was a setting on either the response or XML doc?

private List<rss> GetRSS() { List<rss> rssList = new List<rss>(); try { string url = Properties.Settings.Default.RSSFeedURL; string un = Properties.Settings.Default.RSSUN; string pw = Properties.Settings.Default.RSSPW; if (url != "") { // Make Remote Request Uri uri = new Uri(url); HttpWebRequest wr = (HttpWebRequest)WebRequest.Create(url); if (un != "") { wr.Credentials = new NetworkCredential(un, pw); } // Set the HTTP properties wr.Timeout = 10000; // Read the Response WebResponse resp = wr.GetResponse(); Stream stream = resp.GetResponseStream(); // Load XML Document XmlTextReader reader = new XmlTextReader(stream); reader.XmlResolver = null; XmlDocument doc = new XmlDocument(); doc.Load(reader); //Load rssList; } } catch (Exception ex) { //Bubble Exception up to DoWork and then RunWorkComplete throw; } finally { //Cleanup } return rssList; }
