In your LINQ query xml refers to the Infos element. You could do this instead:

C#

var InfosAttribut = from xml in xdoc.Descendants("Order")
                                    where xml.Descendants("Info").Any(d => (string)d.Attribute("Status") == "Busy")
                                    select xml.Attributes();

xml will now refer to the Order element, and a check is done whether there is any Infos element marked as Busy.
