Forget about byte arrays, memory streams and encodings. Assuming you 
have a string with the markup of the XML document you want to transform 
then simply use an XmlReader over a StringReader
   using (XmlReader reader = XmlReader.Create(new 
StringReader(sOrigXMLContent)))
   {
      ...
      myXslTransform.Transform(reader, null, someWriter);
   }

Your code above also suggests you want a string as the transformation 
result. Based on that it should suffice to do e.g
   string result;
   using (XmlReader reader = XmlReader.Create(new 
StringReader(sOrigXMLContent)))
   {
     StringWriter writer = new StringWriter();
     XslCompiledTransform proc = new XslCompiledTransform();
     proc.Transform(reader, null, writer);
     result = writer.ToString();
   }

The Transform method has lots of overloads taking different types of 
arguments, make use of that instead of creating all those different 
objects (StringBuilder, StringWriter, XmlTextWriter).
