Why this XPathSelectElements() returns false?

Question

Consider the snippet below:

var xpath = "//i[@a='1']";
var item = new XElement("i",
    new XAttribute("a", "1"),
    new XAttribute("b", "2"),
    new XAttribute("c", "3"));

Console.WriteLine(item); // <i a="1" b="2" c="3" />
Console.WriteLine("{0} = {1}", xpath, item.XPathSelectElements(xpath).Any());

I was expecting the .Any() result to be true, but I keep getting false.

Problem is with your root element.

You can also test it with this xml

var item = new XDocument(new XElement("i",
                new XAttribute("a", "1"),
                new XAttribute("b", "2"),
                new XAttribute("c", "3")));

This will return TRUE

`i[@a='1'] = False` – Rubens Farias Jul 05 '18 at 20:40
Trying to match the _root item_ should make no difference for the `//` axis. – zx485 Jul 05 '18 at 20:43
give the snippet a try ;) – Rubens Farias Jul 05 '18 at 20:44

Using self::i[@a='1'] or adding that XElement into a XDocument did the trick.
