When I do something like the following $("div/a"), is there a way to

find(expr) looked like the one but it returns a jQuery object. Can I
interrogate this to see if it is "empty"?
Thanks.

Adrian, to check if that set is empty, try:
var isEmpty = !$("div/a").length
But jQuery has that goodness build in and most of the time you don't
need that check, because
$("div/a").hide();
won't do anything, if the selector "div/a" does not match any elements,
e.g. the jQuery object is empty.
