 1) /.+/ is too greedy. You should use something like /[^]+/ or /.+?/
instead
(second is supported only in Perl-compatible regexps). The best
solution
could be /[^']+?/ however.
 2) /a / doesn't match \n after a.

$body = preg_replace(
'#[Aa]\s[^]*?[Hh][Rr][Ee][Ff]\s*=\s*([\'])([^\']+?)\1[^]*?'
.
'([^]*?)/a[^]*?#s',
'A href=\2 target=_blank class=down_txt' .
'strong\3/strong/a',
$body
);

This regexp is not perfect, but I hope it has enough margin of safety,
at
least if your HTML code is more or less correct. E. g., all href values
must be quoted and '', '', '' and ' without special meaning must
be
written as HTML entities.
