Try this
\[{2}(?:[^]|]+?\|)?([^]]+?)\]{2}

-- It searches for yyy| but makes it optional, either way it will capture
xxx into backreference 1.

You can test it here: http://tinyurl.com/jrz2u

When plugging it into a preg/ereg statement (I've only tested it with preg
though), it's good practice to double up your backslashes -- one for php,
one for the regex engine. So it would look like

$text = ereg_replace('\\[{2}(?:[^]|]+?\\|)?([^]]+?)\\]{2}', '\\1', $text);
