This will be true if there is a node in nodeset, that reterned by
//pageTitle[../linkID = $activeLink] expression, equals to empty string.

True if the first node in nodeset, that reterned by //pageTitle[../linkID =
$activeLink] expression, equals to empty string.

I use string function, 'cause you said
[q]
I'm trying to find the _one_ (well, _first_, I suppose, though there is only
one)
[/q]

 d> The first one seems to work, but the second one doesn't. I'm guessing

Please, be more precise and post some snippets of the original xml.
