You could try something like:
sub is_interesting {
my $name = shift;
# only directories are interesting
return 0 unless -d $name;
# and only those containing input.xml and output.xml
return 0 unless -f $name . "/input.xml";
return 0 unless -f $name . "/output.xml";
return 1;
}
sub preproc {
return grep { is_interesting($_) } @_;
}
Note: All usual disclaimers apply: Untested, you can keep all the bits if/when it breaks, no down payment required, no cash back, use at your own risk, dolphin-safe, contains only white meat...
