[pmwiki-devel] another regex pattern question

[Hans]

so far I got this preg_match_all pattern:

"/\\[([@=])([^\\1][^\\]]*?)($pat)(.*?)\\1\\]/"

to match a [@ ..... $pat ..... @] or [= .... $pat ....=]
sequence.
But it does not match if there is a closing ] inside.
How can i precisely match each individual escape code sequence
containg a string var $pat, without it getting too greedy?

[ followed by = or @, followed by any character, but not by
 characters @] or =] (matching the opening @ or = ), unless
 $pat comes first.

thanks for help on this!
