Just in case anybody else lands here from Google, I was bitten by this error message when using XDocument.Load(Stream) method.

XDocument xDoc = XDocument.Load(xmlStream);

Make sure the stream position is set to 0 (zero) before you try and load the Stream, its an easy mistake I always overlook!

if (xmlStream.Position > 0)
{
    xmlStream.Position = 0;
}
XDocument xDoc = XDocument.Load(xmlStream);

Hi this is odd way but try it once   Read the file content into a string print the string and check whether you are getting proper XML or not  you can use XMLDocument LoadXML xmlstring    I try with your code and same XML without adding any XML declaration it works for me  XmlDocument doc   new XmlDocument            doc Load   H  WorkSpace C  TestDemos TestDemos XMLFile1 xml            XmlNodeList nodes   doc GetElementsByTagName  Product            XmlNode node   null          foreach  XmlNode n in nodes                        Console WriteLine  HI                Its working perfectly fine

Check the trees config file which located in config folder    sometimes  I don t know why  this file became to be empty like someone delete the content inside    keep backup up of this file in your local pc then when this error appear - replace the server file with your local file  This is what i do when this error happened  check the available space on the server  sometimes this is the problem    Good luck

If you are loading the XML file from a remote location  I would check to see if the file is actually being downloaded correctly using a sniffer like Fiddler   I wrote a quick console app to run your code and parse the file and it works fine for me

Make sure you XML looks like this    lt  xml version  1 0  encoding  utf-8   gt   lt rootElement gt       lt  rootElement gt    Also  a blank XML file will return the same Root elements is missing exception  Each XML file must have a root element   node which encloses all the other elements
