Question

I have the following Xml in my Resources.xmltest:

<?xml version="1.0" encoding="utf-8" ?>   
<Response xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://DFISofft.com/SmartPayments/">
    <Result>0</Result>
    <Message>Pending</Message>
    <PNRef>222131</PNRef>
    <ExtData>InvNum=123</ExtData>   
 </Response>

I’ve tried several ways to get the values, Result,Message,PNRef,ExtData, out of it and I’ve had no luck. I always get a null value for the NodePath so it never goes into the loop:

  var XmlDoc = new XmlDocument();

  XmlDoc.LoadXml(Resources.xmltest);
  XmlElement NodePath = (XmlElement) XmlDoc.SelectSingleNode("/Response");

  while (NodePath != null)
  {
    foreach (XmlNode Xml_Node in NodePath)
    {
      Console.WriteLine(Xml_Node.Name + " " + Xml_Node.InnerText);
    }
  }

I’ve tried this:

  XmlNode node3 = XmlDoc.SelectSingleNode("PNRef");
  Console.WriteLine(node3.Value);

  Console.WriteLine(XmlDoc.InnerXml);

  var tst = XmlDoc.GetElementsByTagName("PNRef");
  Console.WriteLine(tst);

And this:

  NodePath = (XmlElement) XmlDoc.SelectSingleNode("/Response");

  if (NodePath != null)
  {
    foreach (XmlNode node in NodePath)
    {
      Console.WriteLine("NodeName: " + Xml_NodeX.Name);
      Console.WriteLine("NodeValue: " + node.InnerText);
    }
   }

Apparently, I’m not getting the xml read/write. I’ve done it with DataSets but they do all the work for you.

Can someone point me in the right direction? I’ve been at this for longer than I should have been already.

Thank you!

That is because the node isn’t called response; you need to take the namespace into account:

var XmlDoc = new XmlDocument();
var nsmgr = new XmlNamespaceManager(XmlDoc.NameTable);
nsmgr.AddNamespace("x", "http://DFISofft.com/SmartPayments/");
XmlDoc.LoadXml(yourXml);
XmlElement NodePath = (XmlElement)XmlDoc.SelectSingleNode("/x:Response", nsmgr);
