Use rx to match UI element names

[Davider]

The name of the element I want to find is a number, which can be matched by the regular expression \d{1,3}. How modify the following code?

var w = wnd.find(1, "*", "Gui").Activate();
var e = w.Elm["STATICTEXT", "1", navig: "pa"].Find(3);
e.MouseClick();
