need to add comments in an existing xml document

Question

I need to add comments in an existing xml document.a sample xml is shown below i need to write code in c#. XML serialization was used to generate this xml any help would be great... thanks in advance

<?xml version="1.0" encoding="utf-8"?>
<Person>
<Name>Job</Name>
<Address>10dcalp</Address>
<Age>12</Age>
</Person>

Answer 1

Try it like this:

        string input = @"<?xml version=""1.0"" encoding=""utf-8""?><Person><Name>Job</Name><Address>10dcalp</Address><Age>12</Age></Person>";
        XDocument doc = XDocument.Parse(input);
        XElement age = doc.Root.Element("Age");
        XComment comm = new XComment("This is comment before Age");
        age.AddBeforeSelf(comm);

This code gets the document, finds the element named "Age" which is expected to be under the root element ("Person") and adds comment before it.
