Best way to get InnerXml of an XElement?

XDocument doc = XDocument.Load(new StreamReader(s));
var templates = from t in doc.Descendants("template")
                where t.Attribute("name").Value == templateName
                select new
                {
                   Subject = t.Element("subject").Value,
                   Body = t.Element("body").ToString()
                };

  <strong>Thinking of using a fake address?</strong>

  Please don't. If we can't verify your address we might just
  have to reject your application.
