//you can use LINQ for that
add below namespace
using System.Xml.Linq;
// just add parent tag in you xml like or if ur xml have then fire linq query over that tag
<Test>
<area id="1">Deverloper</area>
<area>rajni</area>
<area>xyz</area>
</Test>
//After that create object of xdocument like this
XDocument xmldoc = XDocument.Load(@"path of ur xml file/or xml in string form");
//then
var result= xmldoc.Element("Test").Elements("area").Single(a => (int?)a.Attribute("id") == 1).Value;
//This will bring your result.
Thanks
