heheh yeah, me too! Don't know where I would be without people like you on perlmonks - has saved my sanity many many times ;)

BTW - that code works a charm :)

    my $re= qr{\[\[            # opening delimiter
    (               # capture...
      (?:           # a group
        (?!\]\])    #    that does not start with ]]
        .           #    and is a single character long
      )+            # and many of these groups, at least one.
    )
    \]\]              # closing delimiter
    }x;    
    
    $section_contents =~ s{$re}{Process_Tag($1,$hidden_query,$tag_cfg,
+$is_preview)}ge; # process stuff like [[1234]] or [[http://www.site.c
+om]]
