the age old problem of "the root element is missing"

EDN Admin · Feb 10, 2007

Ive done a lot of searching for how to fix this error, and I cant find whats different between everything else and my code. Basically what Im doing is connecting to a bizTalk .asp service, and its being sent fine, and is recieved fine. It uses streams to get back and forth, and if I were to write it out to a string, it works fine. If I pass the same stream into the constructor of another class that parses the stream to xml, it gives the error. Heres the code: 
Encoding encoding = new UTF8Encoding();
byte[] data = encoding.GetBytes(request);
// Prepare web request...
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(this.path); // connect to mustang
WebResponse response; // POSTed response
myRequest.Method = "POST";
myRequest.ContentType = "text/xml";
//myRequest.ContentLength = data.Length;
Stream newStream = myRequest.GetRequestStream();
// Send the data.
newStream.Write(data, 0, data.Length);
response = myRequest.GetResponse();
Stream resStream = response.GetResponseStream();
//encoding = Encoding.UTF8;
StreamReader read = new StreamReader(resStream);
string line = read.ReadToEnd();
TextReader reader = new StringReader(line);
resStream.Seek(0, SeekOrigin.Begin);
IMWebResponse webResponse = new IMWebResponse(resStream);
resStream.Close();
newStream.Close();

return webResponse;
Heres the important part in IMWebResponse 
private void parseHeader(Stream xmlResponse, TextReader reader)
{
XmlDocument xDoc = new XmlDocument();
xDoc.Load(reader); //heres where the error is thrown.
XmlNodeList xmlList = xDoc.SelectNodes("PNAResponse/TransactionHeader");
header.ErrorNumber = xmlList.Item(0).SelectSingleNode("ErrorStatus")["ErrorNumber"].InnerText;
header.ErrorStatus = xmlList.Item(0).SelectSingleNode("ErrorStatus").InnerText;
header.TransID = xmlList.Item(0).SelectSingleNode("TransactionID").InnerText;
header.TimeStamp = DateTime.Parse(xmlList.Item(0).SelectSingleNode("TimeStamp").InnerText); 
}
Ive been doing a lot of playing around with this code, but the original code was something copied and pasted. The original error was the root element is missing, but now with this current code the page wont actually load, it just kinda sits there trying to load. <a title="http://www.doublenatural.com/test.aspx http://www.doublenatural.com/test.aspx www.doublenatural.com/test.aspx is where you can see the lack of action. Its an interesting error, and Im having the darndest time figuring it out. Any thoughts?
