You can do it like this:

var xmlDocument = XDocument.Load("Xml filePath");

var books = xmlDocument
            .Descendants("Specification")
            .Where(x => ((string) x.Element("value")).Contains("John"))
            .Select(x => x.Parent.Parent);

But keep in mind you shouldn't ask for code.First you should do some research, read documentation & tutorials, spend some effort then if you have problems abour your attempt(s) you should come and ask for those specific problems.
