XDocument just reads the first title?

I need to parse xml but my code just parses one title not all.
How can I parse part ?
This is my code:
CustomResponse itemCustom = new CustomResponse ();
XDocument response = XDocument.Parse(responseXml);
XElement rootElement = response.Root;
foreach (XElement sellResponse in rootElement.Elements())
{
itemCustom .ErrorCode = sellResponse.Element("ErrorCode").Value;
itemCustom .ErrorMessage = sellResponse.Element("ErrorMessage").Value;
itemCustom .CustomerID= sellResponse.Element("CustomerID").Value;
itemCustom .CustomerType= sellResponse.Element("CustomerType").Value;
}
This is my xml:
<?xml version="1.0" encoding="utf-8"?>
<TINS_XML_DATA>
<Header>
<ErrorCode>WAATS</ErrorCode>
<ErrorMessage>UTL</ErrorMessage>
</Header>
<Customer>
<CustomerID>UTL11111111111111111111</CustomerID>
<CustomerType>NSell</CustomerType>
</Customer>
</TINS_XML_DATA>

Try something like this:
foreach (XElement sellResponse in rootElement.Elements())
{
if (sellResponse.Name == "Header")
{
itemCustom.ErrorCode = sellResponse.Element("ErrorCode").Value;
itemCustom.ErrorMessage = sellResponse.Element("ErrorMessage").Value;
}
else if (sellResponse.Name == "Customer")
{
itemCustom.CustomerID = sellResponse.Element("CustomerID").Value;
itemCustom.CustomerType = sellResponse.Element("CustomerType").Value;
}
}
Update: You could also use XPath to find required elements as like below:
var xDoc = new XmlDocument();
xDoc.LoadXml(xml);
var errorMessage = xDoc.SelectNodes("//ErrorMessage")[0].InnerText;

This is my solved:
var xDoc = new XmlDocument();
xDoc.LoadXml(responseXml);
itemSell.ErrorCode = xDoc.SelectNodes("//ErrorCode")[0].InnerText;
itemSell.ErrorMessage = xDoc.SelectNodes("//ErrorMessage")[0].InnerText;
itemSell.CustomerID= xDoc.SelectNodes("//CustomerID")[0].InnerText;

Writing xml and reading it back c# with xample xml output

Ok I am using again xmldocument to write an xml file then read it back in simple right but how to get the age this time in this example? I was asked to produce the whole problem before so here it is.
private void button1_Click(object sender, EventArgs e)
{
XmlDocument xmlDoc = new XmlDocument();
XmlNode rootNode = xmlDoc.CreateElement("users");
xmlDoc.AppendChild(rootNode);
XmlNode userNode = xmlDoc.CreateElement("user");
XmlAttribute attribute = xmlDoc.CreateAttribute("age");
attribute.Value = "42";
userNode.Attributes.Append(attribute);
userNode.InnerText = "John Doe";
rootNode.AppendChild(userNode);
userNode = xmlDoc.CreateElement("user");
attribute = xmlDoc.CreateAttribute("age");
attribute.Value = "39";
userNode.Attributes.Append(attribute);
userNode.InnerText = "Jane Doe";
rootNode.AppendChild(userNode);
xmlDoc.Save("c:\\temp\\testdoc.xml");
}
private void button2_Click(object sender, EventArgs e)
{
string files = "c:\\temp\\testdoc.xml";
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(files);
foreach (XmlNode node in xmlDoc)
{
MessageBox.Show(node.SelectSingleNode("user").InnerText);
MessageBox.Show(node.SelectSingleNode("age").InnerText);
}
}
I can read the users name correctly but not the age I get an error.
<users>
<user age="42">John Doe</user>
<user age="39">Jane Doe</user>
</users>

You can access the attributes array directly on the node with
MessageBox.Show(node.SelectSingleNode("user").Attributes["age"].InnerText);

Navigate xml nodes;

Hi I have an xml data returned from another service. It looks like this
<?xml version="1.0" encoding="UTF-8"?>
<response xmlns="http://test.com/group/application" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Response>
<Response>
<ReturnCode>0</ReturnCode>
<Message>Sucess</Message>
<Data>PRINT 'This is a test #2'</Data>
</Response>
</Response>
</response>
I need the value of Data, Message and ReturnCode. The value inside the Data(PRINT 'This is a test #2') node could be single line or thousands of lines..
I am using this C# code to get the values
XmlDocument xm = new XmlDocument();
string Response = obj.getContent(str, 1, 73810, SHA);
//Console.WriteLine("Response" + Response);
xm.LoadXml(Response);
Console.WriteLine(xm.InnerXml);
XmlNode oldCd;
XmlElement root = xm.DocumentElement;
Console.WriteLine(root.InnerText);
oldCd = root.SelectSingleNode("/response/Response/Response/ReturnCode/Message/Data/");
static void Main()
{
try
{
svc obj = new svc();
..
//XmlDocument xm = new XmlDocument();
string rsp = obj.getContent(..;
String myEncodedString;
myEncodedString = obj.XmlDecode(rsp);
XNamespace xmlns = XNamespace.Get("http://xxxx.com/xxx/xx");
XDocument doc = XDocument.Parse(myEncodedString);
Console.WriteLine(obj.Return_Message_Data("ReturnCode", myEncodedString));
Console.WriteLine(obj.Return_Message_Data("Message", myEncodedString));
Console.WriteLine(obj.Return_Message_Data("Data", myEncodedString));
Console.ReadLine();
}
catch (Exception e)
{
Console.WriteLine(e);
Console.ReadLine();
}
}

Try this
XmlDocument xml = new XmlDocument();
xml.LoadXml(myXmlString); //myXmlString is the xml file in string //copying xml to string: string myXmlString = xmldoc.OuterXml.ToString();
XmlNodeList xnList = xml.SelectNodes("/responset[#*]/Response");
foreach (XmlNode xn in xnList)
{
XmlNode response = xn.SelectSingleNode("Response");
if (response != null)
{
string rc = response["ReturnCode"].InnerText;
string msg = example["Message"].InnerText;
string data = example["Data"].InnerText;
}
}

Add attributes using XAttribute

I have a root XML which is like this:
<Root xmlns="http://schemas.datacontract.org/2004/07/" xmlns:t="http://www.w3.org/2001/XMLSchema-instance">
<Element1>somevalue</Element1>
<Data/>
<Root>
I need to add few customer related informaiton like (Name, Age etc) under Data Element Node. So, the result I expect is follows:
<Root xmlns="http://schemas.datacontract.org/2004/07/" xmlns:t="http://www.w3.org/2001/XMLSchema-instance">
<Element1>somevalue</Element1>
<Data>
<Name t:type="xs:string" xmlns="" xmlns:s="http://www.w3.org/2001/XMLSchema">Elvis</Name>
<Address t:type="xs:string" xmlns="" xmlns:s="http://www.w3.org/2001/XMLSchema">Some address</Address>
</Data>
<Root>
How can I achieve this? I am using C#, .net 4.0.
I was trying out the below code, but didn't get the result I was expecting:
string strTemplate = "<Root xmlns='http://schemas.datacontract.org/2004/07/' xmlns:t='http://www.w3.org/2001/XMLSchema-instance'><Element1>somevalue</Element1><Data/></Root>";
XDocument doc = XDocument.Parse(strTemplate);
XElement rootElement = doc.Root;
XElement dataElement = null;
foreach (XElement descendant in rootElement.Descendants())
{
if (descendant.Name.LocalName == "Data")
{
dataElement = descendant;
break;
}
}
string cusData = "<CustData><Name>Elvis</Name><Address>XYZ</Address></CustData>";
XElement customerElements = XElement.Parse(cusData);
if (dataElement != null)
{
foreach (XElement custAttributes in customerElements.Descendants())
{
XNamespace t = "http://www.w3.org/2001/XMLSchema-instance";
var attribute = new XAttribute(t + "type", "xs:string");
var attribute1 = new XAttribute(XNamespace.Xmlns + "s", "http://www.w3.org/2001/XMLSchema");
XElement element = new XElement(custAttributes.Name, attribute, attribute1);
element.Value = custAttributes.Value;
dataElement.Add(element);
}
}
string strPayload = doc.ToString();
When I execute the code I get the following:
<Data xmlns="http://schemas.datacontract.org/2004/07/">
<Name t:type="xs:string" xmlns:t="http://www.w3.org/2001/XMLSchema-instance" xmlns="">Elvis</Name>
<Address t:type="xs:string" xmlns:t="http://www.w3.org/2001/XMLSchema-instance" xmlns="">XYZ</Address>
</Data>
Any help appreciated!
Thanks,

how to determine count of tag

I have a bit of xml file named Sample.xml which is shown below
<?xml version="1.0" encoding="ISO-8859-1"?>
<countries>
<country>
<text>Norway</text>
<value>N</value>
</country>
<country>
<text>Sweden</text>
<value>S</value>
</country>
<country>
<text>France</text>
<value>F</value>
</country>
<country>
<text>Italy</text>
<value>I</value>
</country>
</countries>
i have button named submit(button1).If i click that button i need to display the count(PartitionName="AIX") in a text box named textBox1, means How many PartitionName="AIX" is belonging to Type="NIC"
Can any one give me the c# code
I did like this,,but not able to get the answaer
private void button1_Click(object sender, EventArgs e)
{
XmlDocument doc1 = new XmlDocument();
doc1.Load(#"D:\New Folder\WindowsFormsApplication3\WindowsFormsApplication3\Sample.xml");
XmlNodeList a = doc1.GetElementsByTagName("AIX");
textBox1.Text = a.Count.ToString();
}

here is a quick soln I arrived at using linq. hope you find it useful.
static void Main(string[] args)
{
XElement xElement = XElement.Load(#"C:\Labs\test.xml");
// PartitionName="AIX" is belonging to Type="NIC"
var count = xElement.Descendants().Where(x => x.Name.ToString().Contains("Port")) // namespaces might be used here for faster traversal..
.Where(x => x.HasAttributes && x.Attribute("Type").Value == "NIC")
.Descendants().Where(x => x.Name.ToString().Contains("Client"))
.Where(x => x.Attribute("PartitionName").Value == "AIX").Count();
string str = count.ToString();
Console.WriteLine("Count = {0}", str);
Console.ReadLine();
}

Using xpath something like this:
count(vendor/Slot/Port[#Type='NIC']/Client[#PartitionName='AIX'])
But you have to modify it to support your namespaces.
Also easier and shorter code than going the Linq route for this particular case.
XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);
XmlNamespaceManager nsMgr = new XmlNamespaceManager(doc.NameTable);
nsMgr.AddNamespace("inv", "http://secon.com/Ultravendor");
int count = doc.SelectNodes("inv:vendor/inv:Slot/inv:Port[#Type='NIC']/inv:Client[#PartitionName='AIX']", nsMgr).Count;

XmlDocument doc1 = new XmlDocument();
doc1.Load(#"C:\Labs\test.xml");
XmlNodeList nodes = doc1.GetElementsByTagName("inv:Port");
int count = 0;
foreach (XmlNode childNode in nodes)
{
XmlNodeReader nodeReader = new XmlNodeReader(childNode);
while (nodeReader.Read())
{
if (nodeReader.GetAttribute("PartitionName") == "AIX")
{
count++;
}
}
}
Console.WriteLine("Count = {0}", count);
Console.ReadLine();
