Question

See more:

I have a xml like the following example, which is also used in XML Data Source. I don't want to create a new xml, rather than use this one.

XML

<App>
  <Post id="1" text="Hello"></Post>
  <Post id="2" text="Hello1"></Post>
  <Post id="3" text="Hello2"></Post>
</App>

Now I want to create a c# function to match a "string" with the "id" attribute and return the "text". I have created a function (below) but unable to solve it. Please Help. Thanks in Advance.

C#

public string GetText(string id)
{
  string selected = sid;
  XDocument doc = XDocument.Load(HttpContext.Current.Server.MapPath("application.xml"));
}
