$in is not being opened. Check the return value. Check for errors.

`$in` is not being opened. That seems to be very unlikely. Based on `dir(...)`, `->children` and `->openr`, I am guessing this is Path::Class. Its `openr` throws an error if the file couldn't be opened. Even if `$in` were `undef`, there would need to be a file named `tocsvfd.xml` in the same path as the script, otherwise `XMLin` would throw an error.	[reply] [d/l] [select]
