[Bioperl-l] regexp / protein database

[Mauricio Herrera Cuadra]

Supposing that you have an array with all the desired regexps you want 
to search on a record, you can try something like this:

my @regexp = ("regexp1", "regexp2", "regexp3");
for my $i (0 .. $#regexp) {
     while ($record =~ /$i/g) {
         # Do something fancy
     }
}

Regards,
Mauricio.
