Question

I’ve got unformatted html in a string.

I am trying to format it nicely and output the formatted html back into a string. I’ve been trying to use The System.Web.UI.HtmlTextWriter to no avail:

System.IO.StringWriter wString = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter wHtml = new System.Web.UI.HtmlTextWriter(wString);  wHtml.Write(sMyUnformattedHtml);  string sMyFormattedHtml = wString.ToString(); 

All I get is the unformatted html, is it possible to achieve what I’m trying to do here?

Here’s a function that does exactly that:

    // Attractively format the XML with consistant indentation.      public static String PrettyPrint(String XML)     {         String Result = '';          using (MemoryStream MS = new MemoryStream())         {             using (XmlTextWriter W = new XmlTextWriter(MS, Encoding.Unicode))             {                 XmlDocument D = new XmlDocument();                  try                 {                     // Load the XmlDocument with the XML.                     D.LoadXml(XML);                      W.Formatting = Formatting.Indented;                      // Write the XML into a formatting XmlTextWriter                     D.WriteContentTo(W);                     W.Flush();                     MS.Flush();                      // Have to rewind the MemoryStream in order to read                     // its contents.                     MS.Position = 0;                      // Read MemoryStream contents into a StreamReader.                     StreamReader SR = new StreamReader(MS);                      // Extract the text from the StreamReader.                     String FormattedXML = SR.ReadToEnd();                      Result = FormattedXML;                 }                 catch (XmlException ex)                 {                     Result= ex.ToString();                 }                  W.Close();             }             MS.Close();         }         Debug.WriteLine(Result);         return Result;     }
