And I am reading like this:
XDocument xdoc = XDocument.Load("xmlfile1.xml");
xdoc.Root.Element("name")
it returns null element.

You have to take the XML namespace into account:
XNamespace ns = "http://www.microsoft.com/networking/WLAN/profile/v1";
XElement name = xdoc.Root.Element(ns + "name");

Reading in XML from WPF c#

I'm struggling to read in a "GPX" file to a WPF (c#) project. Sample GPX is provided below. I've tried a number of different options with the same result.
Document is loading ok, but I'm unable to break it down to access the Nodes Directly.
Any help would be greatly appreciated.
Thanks.
private void Simple_Click(object sender, RoutedEventArgs e)
{
XmlDocument xml = new XmlDocument();
xml.Load(#"C:\Users\Jonathon\Desktop\GPX_Data.gpx");
XmlNodeList nodes = xml.SelectNodes("trkpt"); // have tried: double '/' to get nodes at any level (XPath syntax)
//XmlNodeList nodes = xml.SelectNodes("/gpx/trk/trkseg/trkpt");
int count = 0;
foreach (XmlNode xn in nodes)
{
count++;
}
}
}

That's because your xml contains namespaces, so you have to set namespace when querying data.
Consider this approach:
XmlNamespaceManager nsmgr = new XmlNamespaceManager(xml.NameTable);
nsmgr.AddNamespace("x", "http://www.topografix.com/GPX/1/1");
XmlNodeList nodes = xml.SelectNodes("//x:trkpt", nsmgr);
Here we're creating NamespaceManager, setting namespace according to your data xmlns="http://www.topografix.com/GPX/1/1" attribute and using this namespace in XPath.

By XPath selection:
foreach(XElement aElement in xml.XPathSelectElements("/trk/trkseg").Elements())
{
foreach(XNode aXNode in aElement.Nodes())
{
//Access subnodes of trkpt
}
}

Beforehand thanks for answer

First of all, you'll need to generate XSD schemas for your XML. The Government Gateway should provide XSDs for your particular submission domain. If not, you can generate a reasonably good schema from the XML file by using the Visual Studio XML tools under Create Schema from the XML menu.
Once you have a schema file you can use the XSD.exe tool from the Windows SDK to generate service classes. If you have multiple schema files (say, one for the GovTalkMessage wrapper and one for a particular domain, like Inland Revenue in my example below) you can combine them in one service class file:
If the XSD tool is installed in its typical location you can run this command:
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\x64>xsd.exe /c c:\Schemas\GovTalkMessage.xsd C:\ServiceClasses\IREnvelope.xsd /o:C:\GovTalkApplication
Once you have service classes for your XML you can create new objects from your data and serialize them into XML fairly easily. In this code sample I have used AppSettings in the configuration file to store various constant values and a private DataTable called _localData to hold my body data which I am putting into an IR R68 payload (in the element). I am also using a log4net logger here, which is incidental. The CreateIRBody method is something you will have to write for whatever payload you need to include:
public GovTalkMessage CreateRequestMessage(string env)
{
try
{
log.Debug("CreateRequestMessage called");
GovTalkMessageBody Body = new GovTalkMessageBody();
IR68 ir68 = new IR68(_localData);
log.Debug("Creating IR68 body ...");
IRenvelope ire = new IRenvelope();
ire = ir68.CreateIRBody();
//serialize ire into XmlElement and then set Body.Any =
XmlElement xe = GiftAidSubmissionProcessController.SerializeIREnvelope(ire);
XmlElement[] XmlElementIRenvelope = new XmlElement[1];
XmlElementIRenvelope[0] = xe;
Body.Any = XmlElementIRenvelope;
//GovTalkDetails
GovTalkMessageGovTalkDetailsChannelRoutingChannel Channel = new GovTalkMessageGovTalkDetailsChannelRoutingChannel();
Channel.Version = ConfigurationManager.AppSettings["ChannelVersion"];
Channel.Product = ConfigurationManager.AppSettings["ChannelProduct"];
Channel.ItemElementName = ItemChoiceType.URI;
Channel.Item = ConfigurationManager.AppSettings["ChannelURI"];
GovTalkMessageGovTalkDetailsChannelRouting ChannelRouting = new GovTalkMessageGovTalkDetailsChannelRouting();
ChannelRouting.Channel = Channel;
GovTalkMessageGovTalkDetailsKey Key = new GovTalkMessageGovTalkDetailsKey();
Key.Type = ConfigurationManager.AppSettings["GovTalkDetailsKeyType"];
Key.Value = ConfigurationManager.AppSettings["GovTalkDetailsKey"];
GovTalkMessageGovTalkDetails Details = new GovTalkMessageGovTalkDetails();
GovTalkMessageGovTalkDetailsChannelRouting[] ChannelRoutings =
new GovTalkMessageGovTalkDetailsChannelRouting[1];
ChannelRoutings[0] = ChannelRouting;
Details.ChannelRouting = ChannelRoutings;
GovTalkMessageGovTalkDetailsKey[] Keys = new GovTalkMessageGovTalkDetailsKey[1];
Keys[0] = Key;
Details.Keys = Keys;
string[] TargetDetails = new string[1];
TargetDetails[0] = ConfigurationManager.AppSettings["GovTalkDetailsTargetOrganistion"];
Details.TargetDetails = TargetDetails;
//GovTalk Header
GovTalkMessageHeaderSenderDetailsIDAuthenticationAuthentication Authentication = new GovTalkMessageHeaderSenderDetailsIDAuthenticationAuthentication();
switch (ConfigurationManager.AppSettings["SenderAuthenticationMethod"])
{
case "MD5":
Authentication.Method = GovTalkMessageHeaderSenderDetailsIDAuthenticationAuthenticationMethod.MD5;
break;
case "clear":
Authentication.Method = GovTalkMessageHeaderSenderDetailsIDAuthenticationAuthenticationMethod.clear;

IDAuthentication.SenderID = ConfigurationManager.AppSettings["SenderID"];

MessageDetails.Function = GovTalkMessageHeaderMessageDetailsFunction.submit;
MessageDetails.TransformationSpecified = true;
MessageDetails.Transformation = GovTalkMessageHeaderMessageDetailsTransformation.XML;
MessageDetails.GatewayTest = ConfigurationManager.AppSettings["MessageDetailsGatewayTest"];
if (env == "local")
{
MessageDetails.GatewayTimestampSpecified = true;
MessageDetails.GatewayTimestamp = DateTime.Now;
}
else
{
MessageDetails.GatewayTimestampSpecified = false;
MessageDetails.GatewayTimestamp = DateTime.MinValue; }
GovTalkMessageHeader Header = new GovTalkMessageHeader();
Header.MessageDetails = MessageDetails;
Header.SenderDetails = SenderDetails;
GovTalkMessage GovTalkMessage = new hmrcclasses.GovTalkMessage();
GovTalkMessage.EnvelopeVersion = ConfigurationManager.AppSettings["GovTalkMessageEnvelopeVersion"];
GovTalkMessage.Header = Header;
GovTalkMessage.GovTalkDetails = Details;
GovTalkMessage.Body = Body;
log.Info("GovTalkMessage created successfully");
return GovTalkMessage;

{
log.Error(ex);
throw;
}
}
Hope this helps you get started.

Copy whole XML (CRTL+A CTRL+C)
Open Visual Studio and create new Class
Click menu - Edit -> Paste Special -> Paste XML As Classes
after that you can use XmlSerializer to generate that XML
var entity = new GovTalkMessage();
//fill entity properties with data
var writer = new StringWriter();
var serializer = new XmlSerializer(typeof(GovTalkMessage));
serializer.Serialize(writer, entity);
var xmlText = writer.ToString();
//and so on...

This is a whole XML file.

Extraction of Values from Xml SOAP response in C#

I am trying to write down a code to read a SOAP Response message and extract values without success.
I am trying to extract scalar values starting at the "structure" node.
Here is my code:
//Extracting the xml http message.
xmlDoc.LoadXml(xmlHttp.responseText);
XmlNamespaceManager nsmgr = new XmlNamespaceManager(xmlDoc.NameTable);
nsmgr.AddNamespace("ns", "http://messages.ara.algorithmics.com");
nsmgr.AddNamespace("ns2", "http://ws.ara.algorithmics.com");
XmlElement root = xmlDoc.DocumentElement;
XmlNode root1 = root.SelectSingleNode("//structure", nsmgr);
The message is looking like this:

XmlDocument and getting specific Attributes using xPath

I have seen a couple of examples on here where Xpath is used in conjunction with XmlDocument to get a specific attribute from an XmlDocument Node.... Example
Console.WriteLine(xmlDocument.SelectSingleNode("//dataTemplateSpecification/templates/template/elements/element/#name").Value.ToString());
For some reason I am getting a "Object reference not set to an instance of an object." exception. Whenever I run across that particular line of code. I have a little test app that I have set up to test out different things before I put them into my main project...
Here is the code for that...
namespace ReadXml
{
class Program
{
static void Main(string[] args)
{
//string fulXmlPath = System.Web.Hosting.HostingEnvironment.MapPath("~/App_Data/templateExample.xml");
XDocument xDocument = XDocument.Load("C:\\Users\\derekww\\Documents\\XML Documents\\templateExample.xml");
XElement elem = xDocument.Element("dataTemplateSpecification"); ;
XmlDocument xmlDocument = new XmlDocument();
StreamReader file = new StreamReader("C:\\Users\\derekww\\Documents\\XML Documents\\templateExample.xml");
xmlDocument.Load(file);
//XmlDocument theDoc = new XmlDocument();
//using (var xmlReader = xDocument.CreateReader())
//{
// xmlDocument.Load(xmlReader);
//}
//Console.WriteLine(elem.ToString());
XmlNode xNode = xmlDocument.SelectSingleNode("//dataTemplateSpecification/templates/template/elements/element");
Console.WriteLine("WORK PLEASE!!!! {0}", xNode.Value.ToString());
//Console.WriteLine(xmlDocument.SelectSingleNode("//dataTemplateSpecification/templates/template/elements/element/#name").Value.ToString());
//Console.WriteLine("This better Work>>>> {0}", xmlDocument.Attributes["/dataTemplateSpecification/templates/template/elements/element/#name"].Value);
Console.ReadLine();
//Console.WriteLine("This better Work>>>> {0}", xmlDocument.SelectSingleNode("//dataTemplateSpecification/templates/template/elements/element/#name").Value);
//foreach (String AttVal in xmlDocument.SelectSingleNode("//dataTemplateSpecification/templates/template/elements/element/#name").Value)
{
//Console.WriteLine("This better Work>>>> {0}", AttVal);
}
}
}
}
Here is part of the XML that I used...
<?xml version="1.0" encoding="utf-8"?>
<dataTemplateSpecification id="id1" name="name1" xmlns="http://EADIS.upmc.com /DataTemplateSpecification.xsd">
<description xmlns="">
<html>text</html>
</description>
<templates xmlns="">
<template>
<elements>
<element id="element0" name="PatientId" display="Patient ID" dataType="String" value="0101010111111" visable="false" readOnly="true">
<validation>
<rules>
<rule id="0" test="#element0.value == ''">
<fail>
<html><b>Patient ID is null, value must be present</b></html>
</fail>
</rule>
</rules>
</validation>
</element>
</elements>
</template>
<templates>
I just showed you the part that you need to understand the xml structure. I assure you that it is well formed. I think I asked this question before but somehow or the other it didn't get posted (maybe I forgot, who knows). Any help with this would be greatly appreciated. If I come up with a reason for why it isn't working I will be sure to let you guys know.
Thank You.

Why can't you use this XPath:
xmlDocument.SelectSingleNode("//templates/template/elements/element/#name").Value

You need to specify the namespace of the XML file in your code.
See here for more info: How to select xml root node when root node has attribute?
