I have an array which its structure is:
<data>
<id></id>
<list></list>
</data>
And I want to write an array to list node
<data>
<id></id>
<list>
<item>1</item>
<item>2</item>
<item>3</item>
<item>4</item>
</list>
</data>
Then, delete an element in that array:
<data>
<id></id>
<list>
<item>1</item>
<item>3</item>
<item>4</item>
</list>
</data>
Next, modify that array:
<data>
<id></id>
<list>
<item>1</item>
<item>2</item>
<item>3</item>
</list>
</data>
How to write / read/ modify an array which inside the xml array?
Any ideas?
To read:
XDocument doc = XDocument.Load("data.xml");
var listPath = from elements in doc.Elements("data").Elements("list") select elements;
foreach (var docItem in listPath)
{
var itemVar= Convert.ToInt32(doc .Element("item").Value);
}
To write:
XDocument doc = XDocument.Load("data.xml");
var list = doc.Root.Element("list");
list.Add(new XElement("item", value));
To edit:
XDocument doc = XDocument.Load("data.xml");
var list = doc.Root.Element("list");
list.Element("item").Value = newValue;
any powerful and faster solution?

I have a c# console application where I update, add and delete information from an xml which works so far. But when i show the xml in my console with WriteLine it shows like this:
<ArrayOfKunde xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Kunde id="1">
<firstName>Hasan 2</firstName>
<lastName>sad</lastName>
<adress>sdfd</adress>
<birthday>vcxbgf</birthday>
<bankDetails>bcgh</bankDetails>
</Kunde>
<Kunde id="2">
<firstName>ghf</firstName>
<lastName>nbv</lastName>
<adress>bjk</adress>
<birthday>hjvn</birthday>
<bankDetails>jhgj</bankDetails>
</Kunde>
<Kunde id="3">
<firstName>mbn,</firstName>
<lastName>hgj</lastName>
<adress>ghj</adress>
<birthday>ghjg</birthday>
<bankDetails>hghj</bankDetails>
</Kunde>
</ArrayOfKunde>
it is probably due to my code to print it:
string filepath = "customerdatabase2.xml";
var xDoc = XDocument.Load(filepath);
Console.WriteLine(xDoc);
I wanted to ask if there is any way for me to filter what is shown? For example I do not want to show:
<ArrayOfKunde xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
Use: XDocument.Descendants
So your code can be:
string filepath = "customerdatabase2.xml";
var xDoc = XDocument.Load(filepath);
foreach (var node in xDoc.Descendants().Skip(1))
Console.WriteLine(node);
But this is very much tied to your Xml structure. Note that I am skipping 1st descendant because that will be the Top level ArrayOfKunde node.

XDocument doc = XDocument.Load(filename);
IEnumerable<XElement> collection =
doc.Elements("BCIRequest").Elements("Card").Elements("SelectedPIN");

I need to update the element value in the above values. The old value is:
<SelectedPIN>0123</SelectedPIN>
And the new value should be:
<SelectedPIN EncryptedPIN="TKDS" FormNumber="000793906306">****</SelectedPIN>
Can anyone can help me on this?
If I selected the BCIRequest element, it's returning a null value. I've tried many solutions but unable to get one working on this XML file.
There many ways an Xml can be be modified, I prefer XDocument
XDocument doc = XDocument.Parse(input);
foreach (var element in doc.Descendants("SelectedPIN")) // filter if you want single element, in example I modifed for all elements.
{
element.Add(new XAttribute("EncryptedPIN", "TKDS"));
element.Add(new XAttribute("FormNumber", "000793906306"));
element.Value = "xxxxx"; //new value
}
and finally you can save the document using
doc.Save();
Take a look at this Demo
The root node (BCIRequest) contains a namespace so you need to include that into your query. Something like this should work:
XNamespace ns = "urn:xxxxxx:bci:request";
IEnumerable<XElement> collection = doc.Elements(ns + "BCIRequest").Elements(ns + "Card").Elements(ns + "SelectedPIN");
I have a XML which looks like:
<users>
<user id="0">
<name>John</name>
<lastName>Smith</lastName>
<bills>
<bill id="0">
<name>Water</name>
<forMonth>2013-12-01</forMonth>
<money>235</money>
<lastDayToPay>2014-01-02</lastDayToPay>
<payed>False</payed>
</bill>
<bill id="1">
<name>Telephone</name>
<forMonth>2013-11-01</forMonth>
<money>690</money>
<lastDayToPay>2014-01-01</lastDayToPay>
<payed>True</payed>
</bill>
</bills>
</user>
How can i add new bill for the user, i have problem accessing "bills" node and adding element to it. I'm using c#.
use following code
XmlDocument myDocument = new XmlDocument();
myDocument.Load(XMLFile);
XmlNode newNode = myDocument.CreateElement("bill");
//add values;
var requiredNode = myDocument.ChildNodes.OfType<XmlElement>().Where(o => o.Name == "bills").First();
requiredNode.AppendChild(newNode);
myDocument.Save(XMLFile);
I have a xml document like this and I need to access the "employees", "employee" elements so I am trying to use linq's XDocument class to get the employee elements but it always returns empty value.
Sample xml:
<organization>
<metadata>
</metadata>
<main>
<otherInfo>
</otherInfo>
<employeeInfo>
<employees>
<employee>
<id>1</id>
<name>ABC</name>
</employee>
<employee>
<id>2</id>
<name>ASE</name>
</employee>
<employee>
<id>3</id>
<name>XYZ</name>
</employee>
</employees>
</employeeInfo>
</main>
</organization>
C# code:
XDocument xDoc = XDocument.Parse(xmlString);
var allEmployees = from d in xDoc.Descendants("employeeInfo")
from ms in d.Elements("employees")
from m in ms.Elements("employee")
select m;
It kind of depends on what information you need. Your select returns an IEnumerable list.
This code will print out each employee
string xmlString = #"<organization>
<metadata>
</metadata>
<main>
<otherInfo>
</otherInfo>
<employeeInfo>
<employees>
<employee>
<id>1</id>
<name>ABC</name>
</employee>
<employee>
<id>2</id>
<name>ASE</name>
</employee>
<employee>
<id>3</id>
<name>XYZ</name>
</employee>
</employees>
</employeeInfo>
</main>
</organization>";
XDocument xDoc = XDocument.Parse(xmlString);
var allEmployees = from d in xDoc.Descendants("employeeInfo")
from ms in d.Elements("employees")
from m in ms.Elements("employee")
select m;
foreach (var emp in allEmployees) {
Console.WriteLine(emp);
}
Console.Read();
XDocument xDoc = XDocument.Parse(xmlString);
var allEmployees = (from r in xDoc.Descendants("employee")
select new
{
Id = r.Element("id").Value,
Name = r.Element("name").Value
}).ToList();
foreach (var r in allEmployees)
{
Console.WriteLine(r.Id + " " + r.Name);
}
Just use Descendants("Employee");
XDocument xDoc = XDocument.Parse(xmlString);
var allEmployees = xDoc.Descendants("employee").ToList();
I'm trying to get all elements with a given value, "John", from an xml document.
Is this possible with LINQ to XML?
What I want to achieve is to replace all "John" values with "Wayne". I know this can easily be done with xslt, but I need to do this by code.
My XML:
<Root>
<Parents>
<Parent>
<Name>John</Name>
<Age>18</Age>
</Parent>
<Parent>
<Name>John</Name>
<Age>25</Age>
</Parent>
<Parent>
<Name>Peter</Name>
<Age>31</Age>
</Parent>
</Parents>
</Root>
I have tried this:
XmlDocument doc = new XmlDocument();
doc.Load(#"C:/Temp/test.xml");
var elements = doc.Elements().Where(w => w.Value == "John");
foreach (var element in elements)
{
element.Value = "Wayne";
}
You may use System.Xml.Linq.XDocument. It's more easy to work with.
XDocument doc = XDocument.Load(your file path);
var elements = doc.Descendants("Name").Where(i => i.Value == "John");
foreach (var element in elements)
{
element.Value = "Wayne";
}
doc.Save(your save file path);
Here is the output:
<?xml version="1.0" encoding="utf-8"?>
<Root>
<Parents>
<Parent>
<Name>Wayne</Name>
<Age>18</Age>
</Parent>
<Parent>
<Name>Wayne</Name>
<Age>25</Age>
</Parent>
<Parent>
<Name>Peter</Name>
<Age>31</Age>
</Parent>
</Parents>
</Root>
Here is an approach that will get all elements with the value John, regardless of what element (although only at the same level; you'd have to modify it to look at different levels too; you could use the Descendants approach described previously):
XDocument doc = XDocument.Load(#"C:\temp\test.xml");
var ns = doc.Root.GetDefaultNamespace();
var elements = doc.Element(ns + "Root").Element(ns + "Parents").Elements(ns + "Parent").Elements().Where(w => w.Value == "John");
foreach (var element in elements)
{
element.Value = "Wayne";
}
var stream = new FileStream(#"C:\temp\test.xml", FileMode.Create);
doc.Save(stream);
