using .net 2.0

I get this error when calling DataSet.ReadXml(stream).  I am passing a 
memorystream that was passed to XslCompiledTransformer.Transform().  The 
resulting stream has an unprintable character just before the xml declaration.

After a couple of hours I found the issues and decided to use the following 
workaround:

string x = UTF8Encoding.UTF8.GetString(transformedXml.ToArray());
webServerDataSet.ReadXml(new StringReader(x.Trim()));

********original code**********

DataSet webServerDataSet = null;
            XPathDocument xslt;
            XPathDocument xml;
            XslCompiledTransform xslTransformer;
            MemoryStream transformedXml;
            bool blnFilter = false;

            try
            {
                string webServerXML = 
AWebService.GetWebServers(sourceServerId, blnFilter);

                if (!string.IsNullOrEmpty(webServerXML))
                {
                    //retrieve xslt from embedded resource
                    xslt = new XPathDocument(new 
StringReader(Properties.Resources.WebServerXslt));

                    //load webServerXML into an XPathDocument
                    xml = new XPathDocument(new 
System.IO.StringReader(webServerXML.Trim()));

                    //load transformer engin
                    xslTransformer = new XslCompiledTransform();
                    xslTransformer.Load(xslt);

                    using (transformedXml = new MemoryStream() )
                    {
                        //do the transformation and output into the 
memorystream
                        xslTransformer.Transform(xml, null, transformedXml);
                        
                        //load our grouped and sorted xml into a dataset
                        webServerDataSet = new DataSet();
                        string x = 
UTF8Encoding.UTF8.GetString(transformedXml.ToArray());

                        webServerDataSet.ReadXml(new StringReader(x.Trim()));
                    }
