Here's one way: 
sub fgrep_dash_l {
   my $search = shift;
   local $/ = $search;
   my @files;
   while (my $file = glob("*")) {
      open my $fh, "<", $file or warn "error opening $file: $!" and ne
+xt;
      defined(my $buffer = <$fh>) or next;
      push @files, $file if substr($buffer, -length($search)) eq $sear
+ch;
   }
   return @files;
}

@arr = fgrep_dash_l("<value>IsFrequentlyUsed</value>");

Probably not the best WTDI if any of the files are quite large.
