How to determine if XElement.Elements() contains a node with a specific name?

Question

For example for the following XML

 <Order>   <Phone>1254</Phone>   <City>City1</City>   <State>State</State>  </Order> 

I might want to find out whether the XElement contains "City" Node or not.

Answer 1

Just use the other overload for Elements.

bool hasCity = OrderXml.Elements("City").Any(); 

Answer 2

It's been a while since I did XLinq, but here goes my WAG:

from x in XDocument where x.Elements("City").Count > 0 select x 

;
