I have the following piece of code in which I'm trying to split a filename into a prefix, a number, and a suffix:

sub get_split {
  my $filename = shift;
  my $switches = shift;

  my %filesplit;

  my @digits = $filename =~ /(\d+)/g or die "Error: Could not extract 
+a number from filename '$filename'.\n";
  $filesplit{digit} = $digits[$switches->{numindex}];

  ### This won't work for files like 01-file01.html!! FIX!!
  ($filesplit{prefix}, $filesplit{suffix}) = split (/$filesplit{digit}
+/, $filename, 2);
  ### This won't work for files like 01-file01.html!! FIX!!

  return \%filesplit;
}

Where this breaks down is if I'm trying to slice up a filename where the number is repeated more than once and I'm trying to slice the filename at a specific instance (the instance I'm interested in is recorded in $switches->{numindex}), e.g. I would like to be able to split 01-file-01.html into ('01-file-', '01', '.html'). The code above will always split the filename into ('', '01', '-file-01.html') which is frequently not what I want.

Help is, as always, appreciated.
