How to get Single XElement object using Linq for Xml?

Question

I would like to use Linq for Xml to get one XElement from an .xml file by attribute name, similar to how you extract individual objects in Linq to Sql by Id below:

var singleDog = context.Dogs.Single(p => p.Id == int.Parse(Id));

Is it possible?

Answer 1

That's right. Just use something like:

xdoc.Descendants()
    .Where(x => x.HasAttribute("id") && x.Attribute("id")==id)
    .Single();

Maybe a more efficient way to do this, admittedly ...
