Dear monks

I need to read the files contained in a directory and select them according to their extensions. I'd like to use grep as it seems to be a very fast and concise solution, but I am having problems in matching more than one extention at a time. How can improve the following (it doesn't produce any result, the problem being in the regexp in combination with grep)?

    opendir (DIR, "$MyDir") or die "$!";
        my @Documents = grep {/\.[docx|pdf]$/}  readdir DIR;
        my $number_of_files = scalar @Documents;
        print "Total number of files found in folder: $number_of_files
+\n";
    close DIR;
