I have one XML file as follow:

XML

<Employees>
 <Employee>
   <EmpId>10</EmpId>
 </Employee>
 <Employee>
  <EmpId>11</EmpId>
 </Employee>
</Employees>

Using C# I just want to make this file as follow:

XML

<Employees>
 <Employee>
   <EmpId>10</EmpId>
    <EName>AA</EName>
 </Employee>
 <Employee>
  <EmpId>11</EmpId>
   <EName>BB</EName>
 </Employee>
</Employees>

Thank U.

Solution 1

The XML files you show are very small and simple, so you could use probably the simplest way: read the whole file in a DOM structure by using available XML parser into the DOM, System.Xml.XmlDataDocument:
http://msdn.microsoft.com/en-us/library/system.xml.xmldocument%28v=vs.110%29.aspx[^].

You parse the file into DOM, add children to DOM, save it to file.

You tag says C#.2.0, but you did not tell us if you can use .NET Framework 3.5 or later. If you can, you have another option:

You can do something similar, if you prefer, with the class System.Xml.Linq.XDocument, supporting LINQ to XML programming:
http://msdn.microsoft.com/en-us/library/system.xml.linq.xdocument%28v=vs.110%29.aspx[^],
http://msdn.microsoft.com/en-us/library/vstudio/bb387098%28v=vs.100%29.aspx[^].

No issue if you use .Net 3.5
Would you please give the sample example to do the same. But without Linq.
Thank u.

Why should I write a sample? Documentation explains everything. Write your code by yourself, ask further questions if you fave some problems...

I m not asking you to write code, I just want to know the methodoly or logic, If you can?

Brijesh Kr 23-Nov-13 1:54am

One more thing, the link you have posted, i already have gone through. Posting a link is very easy. I can show You more than 50 link.

Sergey Alexandrovich Kryukov 23-Nov-13 1:57am

Stop it. Nobody will want to waste time on something which is not easy on a person with such attitude.
You have done nothing, otherwise you would not ask for help.
Helping lazy people is a waste of time, so please continue on your own.

No use of link you post.
If have used XmlNode.AppendChild(), it appends the node only to last employee node and not to both employee. That is the only problem.

Sergey Alexandrovich Kryukov 23-Nov-13 1:52am

Very nice, not you are going to blame the link. No use of your working capability. If you cannot solve simple problem having a ready-to-use class, nothing can help you.

No,
today or tommorrow i will find the answer definetly and post it here only just wait. I just have been looking for the help, that't is.

Sergey Alexandrovich Kryukov 23-Nov-13 1:59am

Very good. No need to post anything. Of course you can solve the problem. It's just doing some job, nothing else.
Good luck.

Look at the correct answer.

XmlDocument doc = new XmlDocument();
doc.Load("d:\\test\\book.xml");

XmlElement elmRoot = doc.DocumentElement;

foreach (XmlNode n in doc.DocumentElement)
{
XmlElement newtitle = doc.CreateElement("EName");
newtitle.InnerText = "SomeText";
n.AppendChild(newtitle);
}

doc.Save("d:\\book.xml");

XmlDocument doc = new XmlDocument();
           doc.Load("d:\\test\\book.xml");

           XmlElement elmRoot = doc.DocumentElement;

           foreach (XmlNode n in doc.DocumentElement)
           {
               XmlElement newtitle = doc.CreateElement("EName");
               newtitle.InnerText = "SomeText";
              n.AppendChild(newtitle);
           }

            doc.Save("d:\\book.xml");
