Any IDeas....



 

re my first post on this, here is a better (well, Lazier) way:

$string = "a4r[]qy78[]x]y[114[[[[[[|]]]]]]t";
$count = $string =~ s/(\[])/$1/g;
print "$count\n";
# $count is the number of times the desired expression (DU) appears in 
the search string
# $string is the string to be searched
# the regex substitutes the DU for itself. Utterly useless, but a 
side-effect is that the number of substitutions performed is stored in 
$count.
# the $1 variable is a placeholder, it saves you the effort of typing 
the DU twice and possibly making a mistake
