How to hold more than one values in XML element?

xWaarde.Value is overriding with new values and flushing old values.
how to stored multiple values in Xelement.
private XElement[] AddCoordinatenList(XElement childElements)
{
XmlNode xmlCoordinatenNode = Utility.GetMappingValues(Constants.BMCoordinaten, ConnectionType.BM);
XmlNode xWaardeNode = Utility.GetMappingValues(Constants.BMXwaarde, ConnectionType.BM);
XmlNode yWaardeNode = Utility.GetMappingValues(Constants.BMYwaarde, ConnectionType.BM);
XmlNode CoordinateX = Utility.GetMappingValues(Constants.XCoordinate, ConnectionType.BM);
XmlNode CoordinateY = Utility.GetMappingValues(Constants.YCoordinate, ConnectionType.BM);
var coordinatenList = from document in childElements.DescendantsAndSelf() where document.Name.LocalName == xmlCoordinatenNode.Name select document;
List<XElement> xcoordinatenList = new List<XElement>();
XElement xWaarde = new XElement(CoordinateX.Name);
XElement yWaarde = new XElement(CoordinateY.Name);
if (coordinatenList.Count() > 0)
{
foreach (XElement element in coordinatenList.Descendants())
{
if (element.Name.LocalName == xWaardeNode.Name)
{
xWaarde.Value = element.Value;
}
if (element.Name.LocalName == yWaardeNode.Name)
{
yWaarde.Value = element.Value;
}
}
}
return xcoordinatenList.ToArray();
}

It's not possible. Use Attributes:
XAttribute attribute = new XAttribute("name1", <value>);
element.Add(attribute);
attribute = new XAttribute("name2", <value>);
element.Add(attribute);
You can also add a list of child elements or add all strings as one string, separated by a comma for instance.

Need help retrieving XML data using Linq

I am trying to retrieve data from an XML file and return the parsed data in a list. Depending on what I use to access the data (Element or Attributes) I either get null (in case of Element) or something I cannot decipher (in case of Attributes).
XML Looks like this:
<DATA_RESPONSE>
<HEADER>
<MSGID>IS20101P:091317125610:98::34:0</MSGID>
</HEADER>
<DATA>
<ROW ID='IS20101P' PE_NAME='APP-029' PE_ID='4' CODE='4829' DATA='5,1,500,1' />
<ROW ID='IS20101P' PE_NAME='APPS-029' PE_ID='4' CODE='4829' DATA='4,1,500,1' />
...
</DATA>
<SUMMARY>
</SUMMARY>
<ERRORS>
</ERRORS>
</DATA_RESPONSE>
I am using the following to get the data. I read the file and store XML in a string and call a method with this string as argument:
public static Hashtable GetIDSData(string sXMLString)
{
Hashtable result = new Hashtable();
result.Add("Success", false);
result.Add("ErrorMessage", "");
result.Add("ID", "");
result.Add("PE_NAME", "");
result.Add("PE_ID", "");
result.Add("CODE", "");
result.Add("DATA", "");
xmlDoc.InnerXml = sXMLString;
XmlElement root = xmlDoc.DocumentElement;
XDocument doc = XDocument.Parse(sXMLString);
XmlNode node = xmlDoc.SelectSingleNode("DATA_RESPONSE/DATA");
if (node != null)
{
var AddressInfoList = doc.Root.Descendants("ROW").Select(Address => new
{
ID = Address.Attributes("ID")?.ToString(),
PEName = Address.Attributes("PE_NAME")?.ToString(),
PEID = Address.Attributes("PE_ID")?.ToString(),
Code = Address.Attributes("CODE")?.ToString(),
Data = Address.Attributes("DATA")?.ToString(),
}).ToList();
foreach (var AddressInfo in AddressInfoList)
{
if (string.IsNullOrEmpty(AddressInfo.Code))
{
result["Success"] = false;
result["ErrorMessage"] = "Invalid Code; code is empty.";
}
else
{
result["Success"] = true;
result["ErrorMessage"] = "";
result["ID"] = AddressInfo.ID;
result["PE_NAME"] = AddressInfo.PEName;
result["PE_ID"] = AddressInfo.PEID;
result["CODE"] = AddressInfo.Code;
result["DATA"] = AddressInfo.Data;
}
}
return result;
}
In Linq section, if I use Address.Element("ID").Value, I get null returned.
There is no namespace used in XML.

First off, the GetIDSData() method does not compile as is, because at the line xmlDoc.InnerXml = sXMLString, xmlDoc has not been defined.
I'm assuming you want xmlDoc to be an XmlDocument loaded with the contents of the sXMLString parameter, so I'm changing that line to:
XmlDocument xmlDoc = new XmlDocument {InnerXml = sXMLString};
Also, your root variable is never used, so I removed it for clarity.
Now as for the main part of your question, given your current syntax, you are calling .ToString() on a collection of attributes, which is obviously not what you want. To fix this, when you're iterating the AddressInfoList, You want to fetch the attribute values like:
ID = Address.Attributes("ID")?.Single().Value
or
ID = address.Attribute("ID")?.Value
...rather than Address.Attributes("ID")?.ToString() as you have above.

You are not selecting values of attributes. In your code you are selecting attributes. Not sure what are you trying to achieve, but here is my modified version of your code that loads all elements into DataTable
public static DataTable GetIDSData(string sXMLString)
{
DataTable result = new DataTable();
result.Columns.Add("Success");
result.Columns.Add("ErrorMessage");
result.Columns.Add("ID");
result.Columns.Add("PE_NAME");
result.Columns.Add("PE_ID");
result.Columns.Add("CODE");
result.Columns.Add("DATA");
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.InnerXml = sXMLString;
XmlElement root = xmlDoc.DocumentElement;
XDocument doc = XDocument.Parse(sXMLString);
XmlNode node = xmlDoc.SelectSingleNode("DATA_RESPONSE/DATA");
if (node != null)
{
var AddressInfoList = doc.Root.Descendants("ROW").Select(Address => new
{
ID = Address.Attributes("ID").Select(i=>i.Value) ,
PEName = Address.Attributes("PE_NAME").Select(i=>i.Value),
PEID = Address.Attributes("PE_ID").Select(i=>i.Value),
Code = Address.Attributes("CODE").Select(i=>i.Value),
Data = Address.Attributes("DATA").Select(i=>i.Value),
}).ToList();
AddressInfoList.ForEach(e =>
{
e.Code.ToList().ForEach(c =>
{
DataRow row = result.NewRow();
if (!string.IsNullOrEmpty(c))
{
row["Success"] = true;
row["ErrorMessage"] = "";
row["ID"] = e.ID.First();
row["PE_NAME"] = e.PEName.First();
row["PE_ID"] = e.PEID.First();
row["CODE"] = e.Code.First();
row["DATA"] = e.Data.First();
}
else
{
row["Success"] = false;
row["ErrorMessage"] = "Invalid Code; code is empty.";
}
result.Rows.Add(row);
});});
result.Dump();
return result;
}
return result;
}
And this is the result that you will get in your datatable.

ID = Address.Attributes("ID")?.ToString(),
You want to use Attribute(name) (without s) instead:
ID = Address.Attributes("ID")?.Value,

OneNote NavigateTo() responds with hrObjectDoesNotExist(0x80042014) when opening a page

I am trying to programmatically open a one note page. I am doing that in C# and using OneNote2013.

how to get xml nth element name in wpf

public partial class XML_3 : Window
{
public XML_3()
{
this.InitializeComponent();
XmlDocument doc = new XmlDocument();
doc.Load("D:/sample.xml");
XmlNodeList student_list = doc.GetElementsByTagName("Student");
foreach (XmlNode node in student_list)
{
XmlElement student = (XmlElement)node;
int element_count = student.ChildNodes.Count;
}
}
}
In above code.I can get the count of element except root element(Student). now the count is 3.
But i have to get 2ed element name(Kavi),it's attribute element name(ID) and it's child element name(FName,MName).
what should i do to get those stuff.
Please help me...

Use XDocument (why?):
var doc = XDocument.Parse(xml); // OR Load(...)
var nodeCount = doc.Elements().Count();
var secondNode = doc.Elements().Skip(1).First();
var studentName = secondNode.Name;
var studentId = secondNode.Attribute("ID").Value;
or (for your code):
var secondNode = student.ChildNodes[1] as XmlElement;
var studentName = secondNode.LocalName;
var studentId = secondNode.Attributes["ID"];
Added:
var secondNode = student.ChildNodes[1];
var fName =
secondNode.ChildNodes.Cast<XmlElement>().FirstOrDefault(x => x.LocalName == "FName").InnerText;
var mName =
secondNode.ChildNodes.Cast<XmlElement>().FirstOrDefault(x => x.LocalName == "MName").InnerText;
var studentId = secondNode.Attributes["ID"].Value;

Convert xmlstring into XmlNode

i have one xml string like this
string stxml="<Status>Success</Status>";
I also creaated one xml document
XmlDocument doc = new XmlDocument();
XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
doc.AppendChild(docNode);
XmlNode rootNode = doc.CreateElement("StatusList");
doc.AppendChild(rootNode);
i need an output like this.
<StatusList>
<Status>Success</Status>
</StatusList>
How can i achieve this.if we using innerhtml,it will insert.But i want to insert xml string as a xmlnode itself

A very simple way to achieve what you are after is to use the often overlooked XmlDocumentFragment class:
XmlDocument doc = new XmlDocument();
XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
doc.AppendChild(docNode);
XmlNode rootNode = doc.CreateElement("StatusList");
doc.AppendChild(rootNode);
//Create a document fragment and load the xml into it
XmlDocumentFragment fragment = doc.CreateDocumentFragment();
fragment.InnerXml = stxml;
rootNode.AppendChild(fragment);

Using Linq to XML:
string stxml = "<Status>Success</Status>";
XDocument doc = new XDocument(new XDeclaration("1.0", "utf-8", "yes"),
new XElement("StatusList", XElement.Parse(stxml)));

You could instead use the XElement class:
string stxml = "<Status>Success</Status>";
var status = XElement.Parse(stxml);
var statusList = new XElement("StatusList", status);
var output = statusList.ToString(); // looks as you'd like
If you want to write the new statusList content to a file:
statusList.Save(#"C:\yourFile.xml", SaveOptions.None);

you ca try it using xmlwriter
using (XmlWriter writer = XmlWriter.Create("new.xml"))
{
writer.WriteStartDocument();
writer.WriteStartElement("StatusList");
writer.WriteElementString("Status", "Success"); // <-- These are new
writer.WriteEndDocument();
}

From my experience it is always better to work with unique id's i suggest u look in that situation first and then come back to this page, and research/position my code for a try if u did not yet have a solution for it.
I just finished it on my side for my own project, i have modified abit to look more integrated for your project.
Good luck. Sorry for the late response ;-)
