I have an XML in this Format and I want to get List of Line ID and its Name
<ArrayOfLines xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<LineStatus ID="0" StatusDetails="">
<BranchDisruptions />
<Line ID="1" Name="Line1" />
<Status ID="GS" CssClass="GoodService" Description="Good Service" IsActive="true">
<StatusType ID="1" Description="Line" />
</Status>
</LineStatus>
<LineStatus ID="1" StatusDetails="">
<BranchDisruptions />
<Line ID="2" Name="Line2" />
<Status ID="GS" CssClass="GoodService" Description="Good Service" IsActive="true">
<StatusType ID="1" Description="Line" />
</Status>
</LineStatus>
</ArrayOfLines>
and This is the code I have written:
String xmlFilePath = #"C:/myXML.xml";
XDocument xmlFile = XDocument.Load(xmlFilePath);
var query = from c in xmlFile.Descendants("LineStatus") select c;
but it is not returning me any results.
Here is my idea but you have to create list "namesList" and "idList" before. Try this:
XDocument xDoc = XDocument.Load("your xml file");
foreach (var elem in xDoc.Document.Descendants("line"))
{
idList.Add(elem.Attribute("ID").Value);
namesList.Add(elem.Attribute("Name").Value);
}
And you have full controll by index of each list to this data. After that you can also create object of these 2 elements
You have an xml namespace, you need to specify it with element names:
XNamespace ns = "http://www.w3.org/2001/XMLSchema-instance";
var query = from c in xmlFile.Descendants(ns + "LineStatus") select c;
Try this...
String xmlFilePath = #"C:/myXML.xml";
XDocument xmlFile = XDocument.Load(xmlFilePath);
var query = (from c in xmlFile.Descendants("Line")
select new {
ID=c.Attribute("ID").Value,
Name=c.Attribute("Name").Value
}).ToList();;

Any help how can I achieve this query?

You can use XPath extensions
var xdoc = XDocument.Parse(response);
XElement presentations = xdoc.XPathSelectElement("//PresentationElements");
You may use the System.Xml.Linq.XDocument:
//Initialize the XDocument
XDocument doc = XDocument.Parse(yourString);
//your query
var desiredNodes = doc.Descendants("PresentationElements");
Pretty easy, have you tried:
XDocument xml = XDocument.Load("... xml");
var nodes = (from n in xml.Descendants("PresentationElements")
select n).ToList();
You could also project each individual node to an anonymous type using something like:
select new
{
ContentReference = (string)n.Element("ContentReference").Value,
.... etc
}
I have a Xml and i have to get the element name
<Data>
<Test key="G" modifier="control" />
<Test1 key="E" modifier="control" />
<Test3 />
<Test4 />
</Data>
XDocument xd = XDocument.Load("..\\Cmd.xml");
IEnumerable<XElement> xeCmdData = Cmd.XPathSelectElements(".//Data");
foreach (XElement xeData in xeCmdData)
{
// here i am getting the whole xml how to get Element name ...
// Like <Data>
// <Test key="G" modifier="control" />
// <Test1 key="E" modifier="control" />
// <Test3 />
// <Test4 />
// </Data>
}
How to get Element names ?
XDocument xd = XDocument.Load("..\\Cmd.xml");
IEnumerable<string> names = xd.XPathSelectElements("//Data/*")
.Select(e => e.Name.LocalName);
Or without XPath
IEnumerable<string> names = xd.Descendants("Data")
.Elements()
.Select(e => e.Name.LocalName);
Result:
Test
Test1
Test3
Test4

I have to insert the the data according to the id of the aaa element.

if id="1" then data of ritchtextbox will be insert into tia:address node.
i am using the following code.
private void button2_Click(object sender, EventArgs e)
{
XDocument doc = XDocument.Load(#"d:\file.xml");
XNamespace ns = XNamespace.Get("http://tia.com");
var result= (from ele in doc.Descendants("aaa")
where ((string)ele.Attribute("id")) == "1"
select ele.Element(ns+"address")).FirstOrDefault();
if (result != null)
{
result.Value = richTextBox1.Text;
doc.Save(#"d:\file.xml");
}
MessageBox.Show("done");
}
its not working. how i do that?
First of al, the XML markup you have posted is not valid. I think the easiest way to read/write an XML document is Linq-XML. You have to import System.Xml.Linq namespace to use XDocument class and its method. Take a look at MSDN article.
XDocument doc = XDocument.Load(#"c:\file.xml");
var result = (from ele in doc.Descendants("aaa")
where ((string)ele.Attribute("id")) == "1"
select ele.Element("address")).FirstOrDefault();
if (result != null)
{
result.Value = richTextBox1.Text;
doc.Save(#"c:\file.xml");
}
XML document should be:
<?xml version="1.0" encoding="utf-8"?>
<root>
<aaa id="1">
<address>Hello World</address>
</aaa>
<aaa id="2">
<address>
write text of ritchtextbox here</address>
</aaa>
</root>
EDIT:
In OP, XML markup has some issues and I've fixes the markup (added namespace).
<?xml version="1.0" encoding="utf-8"?>
<aaa testitem_id="chapter1" template="hsp_testitem_mc1.xslt" id="1" bankable="true" xmlns:tia="http://tia.com">
<tia:multipleChoiceTestItem total-points="1" questionType="Multiple Choice" sample="false" version_label="1.0">
<tia:directions>
<tia:tiDirectionLine>
<tia:textBody />
</tia:tiDirectionLine>
<tia:address>I have to edited here.(Richtextbox data)</tia:address>
</tia:directions>
</tia:multipleChoiceTestItem>
</aaa>
Code to find <tia:address> and replace its value.
XDocument doc = XDocument.Load(file);
XNamespace ns = XNamespace.Get("http://tia.com");
var result = (from ele in doc.Descendants(ns + "address")
select ele).SingleOrDefault();
if (result != null)
{
result.Value = richTextBox1.Text;
doc.Save(file);
}
EDIT : After changes made by OP in opening post.
XDocument doc = XDocument.Load(file);
//Change the namespace
XNamespace ns = XNamespace.Get("http://xml.thinkcentral.com/pub/xml/hsp/tia");
var result = (
from ele in doc.Descendants(ns + "multipleChoiceTestItem")
where ele.Parent.Attribute("id").Value == "1"
select
ele.Descendants(ns+"address").FirstOrDefault()
).FirstOrDefault();
if (result != null)
{
result.Value = "World";
doc.Save(file);
}

In above XML file using Linq i just
want to extract OrderNumber and
UniqueNumber
OrderNumber="1"
11111111111111111111111111111
Any ideas, suggestions to extract these details?
I can select elements from above xml file but UniqueNumber is not associated with OrderNumber
I am looking for something below (ignore lines where UniqueNumber is not present)
OrderNumber - assosicated UniqueNumber
Update
In "requiredElements" i am expecting two coulmns OrderNumber and UniqueNumber and holding associated values with each other as 1 and 11111 and so one
#region FileOpen with UTF8 Encoding
TextReader sr = new StreamReader(cFileName, Encoding.UTF8);
XDocument reportfile = XDocument.Load(sr, LoadOptions.SetBaseUri);
XElement xd = XElement.Parse(reportfile.ToString());
sr.Close();
#endregion
XNamespace ns = xd.Attribute("xmlns").Value;
var requiredElements = (from resultquery in reportfile.Descendants()
select new
{
OrderNumber = resultquery.Attribute("OrderNumber"),
UniqueNumber= (string)resultquery.Element(AddNameSpace(ns, "UniqueNumber")),
}
);
Here is some sample:
XDocument doc = XDocument.Load(#"file.xml");
XNamespace df = doc.Root.Name.Namespace;
var results = from request in doc.Descendants(df + "Request")
where request.Elements(df + "UniqueData").Elements(df + "UniqueNumber").Any()
select new
{
ordNumber = (int)request.Attribute("OrderNumber"),
uniqueNumber = (decimal)request.Element(df + "UniqueData").Element(df + "UniqueNumber")
};
foreach (var result in results)
{
Console.WriteLine("{0}-{1}", result.ordNumber, result.uniqueNumber);
}
I have a XML file like below:
<report timestamp="3201" reportVersion="2" request="3981135340">
<question timedOut="false" time="3163" attempts="2" correct="true" id="13">
<answer status="attempt">
<radioButton correct="false" value="true" id="17" />
</answer>
<answer status="correct">
<radioButton correct="true" value="true" id="15" />
</answer>
</question>
</report>
I want to read the child nodes based on 'status' attribute of 'answer' node.
Use XmlReader (fastest but forward only), XDocument (LINQ to XML) or XmlDocument. See the examples in the msdn documentation.
Using LINQ to XML:
using System.Xml.Linq;
var doc = XDocument.Parse(xml); // or XDocument.Load()
var elements = from e in doc.Descendants("answer")
where e.Attribute("status").Value == "attempt"
select e;
// elements will be IEnumerable<XElement>
Use XmlDocument and XPath:
XmlDocument document = new XmlDocument();
//here you should load your xml for example with document.Load();
XmlNodeList nodes = document.SelectNodes("/report/question/answer[#status = 'correct']/radioButton");
Just modify the XPath to your needs.
try this one..
foreach (XmlNode xnode in xdoc.SelectNodes("report/question/answer"))
{
if (xnode.Attributes.GetNamedItem("status").Value == "correct")
{
string value = xdoc.SelectSingleNode("report/question/answer[#status='correct']/radioButton").Attributes.GetNamedItem("id").Value;
}
if (xnode.Attributes.GetNamedItem("status").Value == "attempt")
{
string value = xdoc.SelectSingleNode("report/question/answer[#status='attempt']/radioButton").Attributes.GetNamedItem("id").Value;
}
}
