You're testing only the positive case of ifexists, right? You need a
test for the negative case (i.e. the attribute does not exist) too.
Ideally, check that the ifexist actually applies to the right attribute,
like

--format '%(ifexist:<%s>)%(attribute1) %(ifexist:[%s])%(attribute2)'

and manage to get an output like

<foo>
 [bar]
<foobar> [barfoo]

You have a double || that is not useful. Not really harmful either, but
it may distract the reader. You may want to s/||/|/.
