在C＃中从xml数据创建数组

Question

I have the following XML returned when I make an API call. I need to create an array that holds the <status> and <description> values for each of <order_status> , <payment_status> , and <fulfillment_status> . Can anyone share some knowledge that would help me?

<orderwave>
  <call_result>
    <order>
      <order_number>17377</order_number>
      <orderwave_order_number>RWD-336475921</orderwave_order_number>
      <order_status>
        <status>active</status>
        <description>This order is free to be charged and shipped.  It is open in the orderwave workflow.</description>
      </order_status>
      <payment_status>
        <status>declined</status>
        <description>This order has been declined by the payment network.</description>
      </payment_status>
      <fulfillment_status>
        <status>not shipped</status>
        <description>This order has not been allocated for shipment.</description>
      </fulfillment_status>
    </order>
  </call_result>
  <warning_count>0</warning_count>
  <warnings/>
  <error_count>0</error_count>
  <errors/>
</orderwave>

Answer 1

LinqToXML is what you want I believe.

I haven't done this in a while so my syntax might not be perfect.

Something like this:

var xmlSource = contacts.Load(@"../../return.xml");

var q = xmlSource.Descendants("order").SelectMany(x => x.Elements("order_status")

Answer 2

To expand upon my earlier comment, an easy and quick way to do this is with List<T> Class and LINQ to XML .

Use a class to hold the data for each order - for example:

public class Order
{

    public int OrderNumber { get; set; }
    public string OrderStatus { get; set; }
    public string OrderDescription { get; set; }
    public string PaymentStatus { get; set; }
    public string PaymentDescription { get; set; }
    public string FulfillmentStatus { get; set; }
    public string FulfillmentDescription { get; set; }
}

Next, you can load the XML into an XDocument , parse it with LINQ to XML and create a List of Order objects:

// Parse the XML string; you can also load the XML from a file.
XDocument xDoc = XDocument.Parse("<orderwave>....</orderwave>");

// Get a collection of elements under each order node
var orders = (from x in xDoc.Descendants("order")
// Use the data for each order node to create a new instance of the order class
              select new Order
              {
                  OrderNumber = ConvertTo.Int32(x.Element("order_number").Value),
                  OrderStatus = x.Element("order_status").Element("status").Value,
                  OrderDescription = x.Element("order_status").Element("description").Value,
                  PaymentStatus = x.Element("payment_status").Element("status").Value,
                  PaymentDescription = x.Element("payment_status").Element("description").Value,
                  FulfillmentStatus = x.Element("fulfillment_status").Element("status").Value,
                  FulfillmentDescription = x.Element("fulfillment_status").Element("description").Value
              }).ToList();
          // Convert the result to a list of Order objects

This is off the top of my head without testing it, but it should point you in the right direction if you want to use Lists instead of arrays.
