reading elements based on dynamic names, c#, linq to xml, part II

My xml file is set up like this:

<ord>
  <item>
    <sku>123456</sku>
  </item>
</ord>

With the help of kaufMed in another question, I am able to set up a configuration file to tell my application:  You can find item number at <ord><item><sku> then use that information to read my xml file dynamically.,

The code looks like this:

            string itemNo = @"//ord/item/sku";

            try
            {
                foreach (string XMLFileName in FilesIn)
                {
                    XDocument xDoc = XDocument.Load(XMLFileName);

                    foreach (var node in xDoc.XPathSelectElements(itemNo))
                        MessageBox.Show(node.Value);

which successfully returns all the skus in the file.


In reality, a given file will have more than one order, a given order will have more than one item, and descending from the item element, there are other elements besides sku that I need to read.

Is there any way I can enhance the above code to look at a specific occurence of the given node?  Is there any way I can, for example, recognize that I have three orders in the file, then read for each order individually (they do have an order number attribute not shown above, like this:  <ord> OrderNumber=998889), and then look at the item elements within that specific order?

Thanks in advance for any thoughts you might have.
