This is a classical problem of default namespace. Your XML has default namespace declared at the root element :


All elements without prefix are considered in the above mentioned default namespace. To select element in namespace, you need to use XmlNamespaceManager:

var nsmgr = new XmlNamespaceManager(new NameTable());
//register mapping of prefix to namespace uri 
nsmgr.AddNamespace("d", "https://mws.amazonservices.com/Orders/2013-09-01");

string query = "/d:ListOrderItemsResponse/d:ListOrderItemsResult/d:OrderItems/d:OrderItem/d:ItemPrice/d:Amount";
XmlNode node = xd1.SelectSingleNode(query, nsmgr);
string itemPrice = node.InnerText;
