c# Parsing XML issue

I am using this code to try and read this XML below, but it is not read anything in the foreach loop and skipping that. Thanks.

C#

 XElement _xml;
 _xml = XElement.Parse(PostResult);
 foreach (XElement value in _xml.Elements("ServiceDelivery")
                                .Element("StopMonitoringDelivery")
                                .Elements("MonitoredStopVisit"))
          {
             StopFeed _item = new StopFeed();
             _item.A= value.Element("PublishedLineName").Value;
             _item.B = value.Element("DirectionName").Value;

              listBox1.Items.Add(_item);
           }

XML:

<?xml version="1.0" encoding="UTF-8" st开发者_如何转开发andalone="yes"?>

                </MonitoredCall>
            </MonitoredVehicleJourney>
        </MonitoredStopVisit>
    </StopMonitoringDelivery>
</ServiceDelivery>
</Siri>

I think you forgot the namespace. Have a look at XNamespace

XNamespace xn= "http://www.siri.org.uk/";

foreach (XElement value in _xml.Elements(xn+ "ServiceDelivery")
                            .Element(xn+ "StopMonitoringDelivery")
                            .Elements(xn+ "MonitoredStopVisit"))
{
      ....
}

The root element is Siri.

Either use:

XElement value in _xml.Root.Elements("ServiceDelivery")
                            .Element("StopMonitoringDelivery")
                            .Elements("MonitoredStopVisit"))

or

XElement value in _xml.Element("Siri")
                            .Elements("ServiceDelivery")
                            .Element("StopMonitoringDelivery")
                            .Elements("MonitoredStopVisit"))

/B

try _xml.Elements("//ServiceDelivery") or _xml.Elements("Siri/ServiceDelivery"), you forgot that your ServiceDelivery node is child of Siri node.

Or maybe the XML namespace is the problem, check this page and see how XmlNamespaceManager can be used.
