Here is how you can check for it:

        string example = @"<xml>
            <message display='yes'></message>
            </xml>";

        XDocument doc = XDocument.Parse(example);
        if (doc.Element("xml").Element("message") != null)
        {
            // node "message" exists within node "xml" which is located at the root of the document
        }

You can use XDocument class to check for existence of any node at any location in the hierarchy of an XML document. You can load contents from string or file easily.

</Order>

    List<string> getNodes(string path, string nodeName) {

    List<string> nodes = new List<string>(); 

    XDocument xmlDoc = XDocument.Load(path); //Create the XML document type

    foreach (var el in xmlDoc.Descendants(nodeName)) {
            //for debugging
            //nodes.Add(el.Name + " " + el.Value);

            //for production
            nodes.Add(el.Value);
    }
   return nodes;
} //end getNodes

List<string> skuNodes = xml.getNodes(@"AmazonSalesOrders.xml", "SKU");
