Question

I would like to use Linq to Xml to get a single XElement from a .xml file by attribute name, similar to how you retrieve single objects in Linq to Sql by Id below:

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

Is this possible?

Answer 1

Absolutely. Just use something like:

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

There may be a more efficient way of doing it, admittedly…
